XMPP Class

Properties   Methods   Events   Config Settings   Errors  

The XMPP Class is used to create a lightweight messaging client using the XMPP (Jabber) protocol.

Syntax

class ipworks.XMPP

Remarks

The XMPP class supports both plaintext and SSL/TLS connections. When connecting over SSL/TLS the on_ssl_server_authentication event allows you to check the server identity and other security attributes. The on_ssl_status event provides information about the SSL handshake. Additional SSL related settings are also supported via the config method.

A call to the connect_to method will perform the entire logon process after which a on_connected event will fire indicating connection status. For simplicity, the entire interface is synchronous; the class will not return until a call is completed.

After a successful connection, the class will automatically begin the process of receiving the user's buddy list. The class will parse the XML as it comes in from the server and will set the appropriate properties. Once the entire buddy list has been retrieved, a on_sync event will fire.

Sending a message is as simple as calling a single method. One call to the send_message method will cause the class to connect if it has not already done so, send the specified message to a specified user, and return to the original connection state.

The XMPP Class interface supports messaging, list and presence management. Other features of the XMPP protocol are supported through the send_command method and on_pi_trail event.

Example (Connecting and Sending a Message)

IMControl.ConnectTo("myusername", "mypassword") IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser") Example (Sending a Single Message)

IMControl.User = "myusername" IMControl.Password = "mypassword" IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser")

Remarks

message_type is the type of the message as specified in the XMPP RFC. The possible values are defined in the protocol specification as follows:

password Property

This is the user's password.

Syntax

def get_password() -> str: ...
def set_password(value: str) -> None: ...

password = property(get_password, set_password)

Default Value

""

Remarks

This must be set before a connection is attempted. If a call to the connect method is made specifying a password, the password property will contain that password.

presence Property

This is the availability of the entity.

Syntax

def get_presence() -> int: ...
def set_presence(value: int) -> None: ...

presence = property(get_presence, set_presence)

Default Value

1

Remarks

When the class completes the initial log in, it will send information telling other entities subscribed to this entity's presence that it is online. The application must provide different status and availability information as the user changes them.

The presence property has one of four values representing general information about the user's status as defined in the Jabber protocol specification:

By default, the class sets the client presence to pcChat, meaning that the user is available. To change the initial status sent by the class set presence to the desired presence before calling connect.

Note: offline is not officially supported by the XMPP specification, however some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an on_error.

The status property is a pure-text string representing the user's presence information. Its value maybe be any random string, including the empty string, "".

Whenever the value in presence or status are changed, the class will send that information to the server. If the application or user wishes to associate a specific status message with a new presence value, it should use the change_presence method. change_presence will update both the presence and status properties, and then send that information to the server.

Note: It is recommended to use the change_presence method instead of setting this property.

resource Property

This is the resource for the current session.

Syntax

def get_resource() -> str: ...
def set_resource(value: str) -> None: ...

resource = property(get_resource, set_resource)

Default Value

"IPWorks XMPP Agent"

Remarks

Whenever an entity logs in to an XMPP (Jabber) server, it must provide account information as well as a resource. Resources allow multiple clients to log in using the same account. The server will forward all messages and PI data aimed at a specific resource to that resource. If a command or message is to be sent to a Jabber ID with no specified resource, the server will push that command or message out to all connected resources.

server_domain Property

The XMPP server's domain.

Syntax

def get_server_domain() -> str: ...
def set_server_domain(value: str) -> None: ...

server_domain = property(get_server_domain, set_server_domain)

ssl_cert_encoded = property(get_ssl_cert_encoded, set_ssl_cert_encoded)

Default Value

""

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The ssl_cert_store and ssl_cert_subject properties also may be used to specify a certificate.

When ssl_cert_encoded is set, a search is initiated in the current ssl_cert_store for the private key of the certificate. If the key is found, ssl_cert_subject is updated to reflect the full subject of the selected certificate; otherwise, ssl_cert_subject is set to an empty string.

ssl_cert_store Property

This is the name of the certificate store for the client certificate.

Syntax

def get_ssl_cert_store() -> bytes: ...
def set_ssl_cert_store(value: bytes) -> None: ...

ssl_cert_store = property(get_ssl_cert_store, set_ssl_cert_store)

Default Value

"MY"

Remarks

This is the name of the certificate store for the client certificate.

The ssl_cert_store_type property denotes the type of the certificate store specified by ssl_cert_store. If the store is password protected, specify the password in ssl_cert_store_password.

ssl_cert_store is used in conjunction with the ssl_cert_subject property to specify client certificates. If ssl_cert_store has a value, and ssl_cert_subject or ssl_cert_encoded is set, a search for a certificate is initiated. Please see the ssl_cert_subject property for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

ssl_cert_store_password Property

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

ssl_cert_subject Property

This is the subject of the certificate used for client authentication.

Syntax

def get_ssl_cert_subject() -> str: ...
def set_ssl_cert_subject(value: str) -> None: ...

ssl_cert_subject = property(get_ssl_cert_subject, set_ssl_cert_subject)

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

If a field value contains a comma it must be quoted.

FALSE

Remarks

This setting specifies whether TLS/SSL is enabled in the class. When False (default) the class operates in plaintext mode. When True TLS/SSL is enabled.

TLS/SSL may also be enabled by setting ssl_start_mode. Setting ssl_start_mode will automatically update this property value.

ssl_provider Property

This specifies the SSL/TLS implementation to use.

Syntax

def get_ssl_provider() -> int: ...
def set_ssl_provider(value: int) -> None: ...

ssl_provider = property(get_ssl_provider, set_ssl_provider)

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

ssl_server_cert_encoded Property

This is the certificate (PEM/base64 encoded).

Syntax

def get_ssl_server_cert_encoded() -> bytes: ...

ssl_server_cert_encoded = property(get_ssl_server_cert_encoded, None)

Default Value

""

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The ssl_server_cert_store and ssl_server_cert_subject properties also may be used to specify a certificate.

When ssl_server_cert_encoded is set, a search is initiated in the current ssl_server_cert_store for the private key of the certificate.

This property is read-only.

ssl_start_mode Property

Determines how the class starts the SSL negotiation.

Syntax

def get_ssl_start_mode() -> int: ...
def set_ssl_start_mode(value: int) -> None: ...

ssl_start_mode = property(get_ssl_start_mode, set_ssl_start_mode)

Default Value

3

Remarks

The ssl_start_mode property may have one of the following values:

status Property

Description of the availability of this entity.

Syntax

def get_status() -> str: ...
def set_status(value: str) -> None: ...

status = property(get_status, set_status)

Default Value

"Available for Chat."

Remarks

When the class completes the initial log in, it will send information telling other entities subscribed to this entity's presence that it is online. The application must provide different status and availability information as the user changes them.

The presence property has one of four values representing general information about the user's status as defined in the Jabber protocol specification:

By default, the class sets the client presence to pcChat, meaning that the user is available. To change the initial status sent by the class set presence to the desired presence before calling connect.

Note: offline is not officially supported by the XMPP specification, however some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an on_error.

The status property is a pure-text string representing the user's presence information. Its value maybe be any random string, including the empty string, "".

Whenever the value in presence or status are changed, the class will send that information to the server. If the application or user wishes to associate a specific status message with a new presence value, it should use the change_presence method. change_presence will update both the presence and status properties, and then send that information to the server.

Note: It is recommended to use the change_presence method instead of setting this property.

timeout Property

A timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

Default Value

60

Remarks

If the timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use do_events to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If timeout expires, and the operation is not yet complete, the class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by timeout seconds when any amount of data is successfully sent or received.

The default value for the timeout property is 60 seconds.

user Property

The user portion of this entity's Jabber ID.

Syntax

def get_user() -> str: ...
def set_user(value: str) -> None: ...

user = property(get_user, set_user)

Default Value

""

Remarks

The user property is a unique username associated with this entity and set at time of registration under the field "user".

user_domain Property

Gets or sets the domain value used for Jabber IDs.

Syntax

def get_user_domain() -> str: ...
def set_user_domain(value: str) -> None: ...

user_domain = property(get_user_domain, set_user_domain)

Default Value

""

Remarks

A Jabber ID (JID) is a unique identifier of the format "user@domain/resource". user@domain denotes the account by username and domain. The resource is given during the login process to distinguish individual connections under the same account. If the im_server contains multiple domains, this property setting allows the user to specify the domain under which to login.

If domain is empty, the value in im_server is used by default when creating the client's JID.

user_info_count Property

Syntax

def get_user_info_field(field_index: int) -> str: ...
def set_user_info_field(field_index: int, value: str) -> None: ...

Default Value

""

Remarks

This is the name of the current property necessary for registration.

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

The field_index parameter specifies the index of the item in the array. The size of the array is controlled by the user_info_count property.

user_info_value Property

This is the value for the current registration property, and should be set after calling QueryRegister and before calling Register .

Syntax

def get_user_info_value(field_index: int) -> str: ...
def set_user_info_value(field_index: int, value: str) -> None: ...

Default Value

""

Remarks

This is the value for the current registration field, and should be set after calling query_register and before calling register.

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

The field_index parameter specifies the index of the item in the array. The size of the array is controlled by the user_info_count property.

add Method

This method will add an entity to this entity's roster.

Syntax

def add(jabber_id: str, name: str, groups: str) -> None: ...

Remarks

JabberId is the Jabber ID of the entity to be added. It should be of form "user@host". If no hostname is specified, the class will assume the user's account is with the server in im_server, and will append that hostname to JabberId before sending the request.

Name will contain the name that is to be associated with JabberId in this entity's roster. It may be the empty string, "".

Groups is either the empty string ("") or a comma- separated list of groups to which JabberId is to be added. If JabberId already exists in the buddy list, it will be updated to exist only in the specified groups. A buddy's group list can also be modified by the buddies property.

The add method will make a subscription request to the presence of the specified JabberId. Upon receiving this request, the server will add an entry into this user's buddy list with a subscription of type subscriptionNone (0) if there was no previous entry (if this user has already allowed JabberId to subscribe to this user's presence, there will already be an entry of type subscriptionFrom (2)). If the contact chooses to allow the subscription, the server will update the entry and a on_buddy_update event will fire with the new subscription value (subscriptionTo (1) if this is a new contact, or subscriptionBoth (3) if the contact is now mutual).

The XMPP protocol permits XMPP (Jabber) clients to communicate with foreign IM networks such as AIM, MSN, SMS, and others through the use of gateway servers that translate between the foreign protocol and XMPP. When sending or receiving presence information, messages, or subscription requests, Domain will be a gateway for the foreign network on which the contact resides and with which this user has registered an account for that foreign network. The register method can be used to register with a foreign network gateway.

cancel Method

This will cancel another entity's subscription to this entity's presence.

Syntax

def cancel(jabber_id: str) -> None: ...

Remarks

If for any reason the user should want to undo a previously granted subscription, this can be achieved through the cancel method. The method will unsubscribe the target from this user's presence, thus preventing the target from seeing this user in the future.

change_password Method

This method will change the current user's password.

Syntax

def change_password(password: str) -> None: ...

Remarks

This method changes the current user's password to the password that is specified. The class must be connected to the server when this method is called.

change_presence Method

This method will set the availability and status of this entity.

Syntax

def change_presence(presence_code: int, status: str) -> None: ...

Remarks

PresenceCode should correspond the possible values of the presence property:

By default, the class sets the client presence to pcChat, meaning that the user is available. To change the initial status sent by the class set presence to the desired presence before calling connect.

Note: offline is not officially supported by the XMPP specification, however some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an on_error.

Status can be any random string, including the empty string "".

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

connect Method

This method will connect the class to the server.

Syntax

def connect() -> None: ...

Remarks

The connect method performs the entire connection routine. This includes connection to the im_server, authenticating with the specified user and password, and session initialization.

The on_connected event will fire once for the initial TCP connection and again when the XMPP Logon is complete.

connect_to Method

This method will connect the class to the server.

Syntax

def connect_to(user: str, password: str) -> None: ...

Remarks

The connect_to method performs the entire connection routine. This includes connection to the im_server, user logon and authentication, and session initialization.

The on_connected event will fire once for the initial TCP connection and again when the XMPP Logon is complete.

Since connect_to is called with a user and password specified, the user and password properties will updated accordingly.

disconnect Method

This method disconnects the class from the server.

Syntax

def disconnect() -> None: ...

Remarks

The disconnect method will send the disconnect command to the notification server. Upon disconnection, a on_disconnected event will be fired.

do_events Method

This method processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

interrupt Method

Interrupt the current method.

Syntax

def interrupt() -> None: ...

Remarks

If there is no method in progress, interrupt simply returns, doing nothing.

probe_presence Method

Use this method to probe for another entity's presence.

Syntax

def probe_presence(jabber_id: str) -> None: ...

Remarks

In the case that the user needs to update a particular entity's presence this method can be used to retrieve it. After a successful call, the server will either respond with the last known presence for Jabber, or will send a presence element of type "error". In either case, the respond will be returned by a on_presence event.

query_register Method

This method queries a server for the necessary registration fields.

Syntax

def query_register(xmpp_server: str) -> None: ...

Remarks

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

register Method

This method registers an account with a server.

Syntax

def register(xmpp_server: str) -> None: ...

Remarks

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

A new account can be registered at any time, including while the class is logged into the host under an existing account.

remove Method

This method will remove an entity from this entity's roster.

Syntax

def remove(jabber_id: str, name: str, group: str) -> None: ...

Remarks

JabberId is the Jabber ID of the entity to be removed. It should be of form "user@host". If no hostname is specified, the class will assume the user's account is with the server in im_server, and will append that hostname to JabberId before sending the request.

Name should contain the name that is to be associated with JabberId in this entity's roster. It may be the empty string, "".

Groups may be either the empty string ("") or a comma- separated list of groups from which JabberId is to be removed. If no group is specified, the buddy will be completely removed from the buddy list.

After calling the remove method, the server will remove the entry from the server-side roster, and will push the result out to all connected resources. A on_buddy_update event will fire with subscription of type subscriptionRemove, and the entry will be removed from the Jabber class's internally stored list.

reset Method

Reset the class.

Syntax

def reset() -> None: ...

Remarks

This method will reset the class's properties to their default values.

retrieve_roster Method

This method will retrieve this entity's roster from the server.

Syntax

def retrieve_roster() -> None: ...

Remarks

After the class connects, it will automatically send a request to the server to retrieve the roster. However, should the user or application wish to update the entire roster, this method may be used to do so.

After a successful call to the retrieve_roster method, the server will respond with this entity's roster. The class will parse the roster and fire the on_sync event once per item. This event may also fire for each entity added to or removed from the roster.

send_command Method

This method sends a command to the server.

Syntax

def send_command(command: str) -> None: ...

Remarks

The send_command method will send the Command parameter to the server. The command must be in valid XML format, and must be recognizable to the im_server.

The send_command method should only be used by programmers or users who are connecting to non-standard servers whose command list is not covered by the class. Any responses that are defined in the protocol specification will be returned by the appropriate event. Any non-standard IQ message will be returned by the on_iq event. All other responses will be returned by the on_pi_trail event.

send_file Method

Sends a file to the specified user.

Syntax

def send_file(jabber_id: str) -> None: ...

Remarks

This method sends the file specified by local_file to the user specified by the JabberId parameter.

JabberId is the intended recipient of the message. It is of the form user@domain/resource. If a resource is not supplied, all logged-in instances of the user's account will receive the message.

The class supports sending files using In-Band Bystestreams as defined in XEP-0047 and XEP-0096.

send_message Method

This method will send a message to the specified user.

Syntax

def send_message(jabber_id: str) -> str: ...

Remarks

JabberId is the intended recipient of the message. It is of the form user@domain/resource. If a resource is not supplied, all logged-in instances of the user's account will receive the message.

The class associates several properties with messages it receives and sends. When it receives a message, the class will parse out the corresponding values and set these properties before firing a on_message_in event. After the event returns control to the class, the properties will be cleared (ie, they will be set to the empty string, "").

Before sending a message, the application should set the appropriate properties to be associated with the message. The class will send only properties with non-empty string values (""), and will clear all properties after a successful send.

The associated properties are the following:

If the parameter passed to send_message is prefixed with "@" the component will interpret the value as a domain when constructing the message. This allows for sending directly to sub-domains.

Note: the XMPP class will generate and return a unique identifier for each message sent. This identifier can be used to track messages in conjunction with various Jabber Extension Protocols.

set_user_info_field Method

This method will add a user information field for registration.

Syntax

def set_user_info_field(field: str, value: str) -> None: ...

Remarks

This method will search through user_info for the field name in Field and set the corresponding value to Value. If the field was not previously contained in user_info, it will automatically added.

Before a registration can be attempted, the application should use the query_register method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server, and will populate the user_info properties accordingly. After a successful query, all entries in user_info values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification as follows:

After the user has set all of the values in user_info, and added any extra fields they may wish to include in their registration, the application should make a call to register.

If the class is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

subscribe_to Method

Use this method to subscribe to another entity's presence.

Syntax

def subscribe_to(jabber_id: str) -> None: ...

Remarks

This method will send a request for a subscription to JabberId's presence. If the entity allows the subscription, a new item will be stored in the buddy list with the appropriate subscription type. Otherwise, no change will take place.

unregister Method

This method cancels an account with the host.

Syntax

def unregister() -> None: ...

Remarks

If the user or application wishes to terminate an account with the im_server it should make a call to this method. After a successful call, the account will be canceled and the class will be logged off the server, but not disconnected.

unsubscribe_to Method

This method will cancel a subscription to another entity's presence.

Syntax

def unsubscribe_to(jabber_id: str) -> None: ...

Remarks

This method will inform the server of the cancellation of subscription to JabberId's presence. After a successful call the subscription type of the associated buddy list item will be updated.

update_buddy_group Method

Updates the buddy's associatd groups.

Syntax

def update_buddy_group(buddy_index: int, group: str) -> None: ...

Remarks

This method updates the associated groups for the buddy specified by BuddyIndex.

After the on_sync event has fired the buddy_group property is populated with a comma-separated list of groups for each buddy. To update the groups for a buddy call this method with the buddy's index and the comma-separate list of groups the buddy should be associated with. Setting Group to empty string ("") will cause the buddy to be completely disassociated from all groups.

on_buddy_update Event

This event is fired whenever a roster entry is updated.

Syntax

class XMPPBuddyUpdateEventParams(object):
  @property
  def buddy_idx() -> int: ...

# In class XMPP:
@property

Please refer to the Error Codes section for more information.

on_end_transfer Event

Fired when a file transfer completes.

Syntax

class XMPPEndTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def file_id() -> str: ...

  @property

@on_message_in.setter
def on_message_in(event_hook: Callable[[XMPPMessageInEventParams], None]) -> None: ...

Remarks

When a message is received, the XMPP class will parse the sender's Jabber ID into the From, Domain, and Resource fields. These parameters can be used to track the exact instance of a user's account that originated the message.

MessageId can be used with Jabber extension protocols. The MessageText parameter is the plaintext portion of the message body. MessageHTML will contain any HTML from the message.

Type the type of message received. See message_type for a list of possible values. For message of type "headline", Subject will reflect the subject of the message. For messages of type "chat", Thread will report the conversation thread for which the current message is a follow-up.

Other will contains any extra data associated with the message but not defined by the XMPP-IM protocol.

on_pi_trail Event

This event is fired for all protocol messages.

@on_pi_trail.setter
def on_pi_trail(event_hook: Callable[[XMPPPITrailEventParams], None]) -> None: ...

Remarks

The on_pi_trail event is useful for debugging purposes. It shows all the interaction between the client and the server, line by line.

SessionId will hold the session number that originated the PI. A value of 0 is reserved for all PI dealing with the im_server.

The direction parameter shows the originator of the message:

The Pi parameter contains the PI message.

on_presence Event

This event is fired when the presence of a subscribed entity changes.

Syntax

class XMPPPresenceEventParams(object):
  @property
  def user() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def resource() -> str: ...

  @property
  def availability() -> int: ...

  @property
  def status() -> str: ...

# In class XMPP:
@property
def on_presence() -> Callable[[XMPPPresenceEventParams], None]: ...
@on_presence.setter
def on_presence(event_hook: Callable[[XMPPPresenceEventParams], None]) -> None: ...

Remarks

This event contains the availability and status information of a particular Jabber entity to whom this entity has a subscription.

Because a user can log in multiple times using the same account, the XMPP class will parse the user's Jabber ID into the User, Domain and Resource parameters so that the client can easily track which instance of the account sent the presence.

The XMPP protocol permits XMPP (Jabber) clients to communicate with foreign IM networks such as AIM, MSN, SMS, and others through the use of gateway servers that translate between the foreign protocol and XMPP. When sending or receiving presence information, messages, or subscription requests, Domain will be a gateway for the foreign network on which the contact resides and with which this user has registered an account for that foreign network. The register method can be used to register with a foreign network gateway.

Availability corresponds to the presence property of the class, with the same possible values:

By default, the class sets the client presence to pcChat, meaning that the user is available. To change the initial status sent by the class set presence to the desired presence before calling connect.

Note: offline is not officially supported by the XMPP specification, however some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an on_error.

Status corresponds to the status property. This value may be any random string, including the empty string, "".

on_ready_to_send Event

This event is fired when the class is ready to send data.

Syntax

class XMPPReadyToSendEventParams(object):
# In class XMPP:
@property
def on_ready_to_send() -> Callable[[XMPPReadyToSendEventParams], None]: ...
@on_ready_to_send.setter
def on_ready_to_send(event_hook: Callable[[XMPPReadyToSendEventParams], None]) -> None: ...

Remarks

The on_ready_to_send event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed data_to_send. This event also is fired immediately after a connection to the remote host is established.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class XMPPSSLServerAuthenticationEventParams(object):
  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

  @property
  def status() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class XMPP:
@property
def on_ssl_server_authentication() -> Callable[[XMPPSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[XMPPSSLServerAuthenticationEventParams], None]) -> None: ...

Remarks

This event is where the client can decide whether to continue with the connection process or not. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether to continue or not.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string "OK"). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

on_ssl_status Event

Shows the progress of the secure connection.

Syntax

class XMPPSSLStatusEventParams(object):
  @property
  def message() -> str: ...

# In class XMPP:
@property
def on_ssl_status() -> Callable[[XMPPSSLStatusEventParams], None]: ...
@on_ssl_status.setter
def on_ssl_status(event_hook: Callable[[XMPPSSLStatusEventParams], None]) -> None: ...

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

on_start_transfer Event

Fired when a file transfer begins.

Syntax

class XMPPStartTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def file_id() -> str: ...

  @property
  def user() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def resource() -> str: ...

  @property
  def filename() -> str: ...
  @filename.setter
  def filename(value) -> None: ...

  @property
  def datetime() -> str: ...

  @property
  def size() -> int: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class XMPP:
@property
def on_start_transfer() -> Callable[[XMPPStartTransferEventParams], None]: ...
@on_start_transfer.setter
def on_start_transfer(event_hook: Callable[[XMPPStartTransferEventParams], None]) -> None: ...

Remarks

When a file is received, the XMPP component will parse the sender's Jabber ID into the User, Domain, and Resource fields. The FileId and Filename parameters identify the current transfer. Within this event you may override the Filename by setting the Filename parameter. At this time you may also set local_directory if it is not already set.

When a sending a file, the XMPP component will parse the receiver's Jabber ID into the User, Domain, and Resource fields.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

on_subscription_request Event

This event fires when a subscription request is received.

Syntax

class XMPPSubscriptionRequestEventParams(object):
  @property
  def from_() -> str: ...

  @property
  def domain() -> str: ...

  @property
  def accept() -> bool: ...
  @accept.setter
  def accept(value) -> None: ...

# In class XMPP:
@property
def on_subscription_request() -> Callable[[XMPPSubscriptionRequestEventParams], None]: ...
@on_subscription_request.setter
def on_subscription_request(event_hook: Callable[[XMPPSubscriptionRequestEventParams], None]) -> None: ...

Remarks

This event fires whenever another XMPP entity requests a subscription to this entity's presence. The XMPP class will parse the requesting entity's Jabber ID into the From and Domain parameters. There is no need to know which resource sent the request, since all instances of the requesting entity's account have access to the same roster.

Accept will initially be false, but setting it to true will cause the XMPP class to allow the remote subscription. Otherwise, the XMPP class will actively deny the subscription request.

on_sync Event

This event fires upon a complete information synchronization with the server.

Syntax

class XMPPSyncEventParams(object):
# In class XMPP:
@property
def on_sync() -> Callable[[XMPPSyncEventParams], None]: ...
@on_sync.setter
def on_sync(event_hook: Callable[[XMPPSyncEventParams], None]) -> None: ...

Remarks

The on_sync event will fire after each successful call to the retrieve_roster method. When the event fires, the buddy list, or roster, will be completely retrieved and the buddies properties will be filled out accordingly:

Please refer to buddies properties property for more information.

on_transfer Event

Fired during file transfer.

Syntax

class XMPPTransferEventParams(object):
  @property
  def direction() -> int: ...

  @property
  def file_id() -> str: ...

  @property
  def filename() -> str: ...

  @property
  def bytes_transferred() -> int: ...

  @property
  def percent_done() -> int: ...

  @property
  def text() -> bytes: ...

  @property
  def cancel() -> bool: ...
  @cancel.setter
  def cancel(value) -> None: ...

# In class XMPP:
@property
def on_transfer() -> Callable[[XMPPTransferEventParams], None]: ...
@on_transfer.setter
def on_transfer(event_hook: Callable[[XMPPTransferEventParams], None]) -> None: ...

Remarks

This event will fire when sending or receiving. One or more Transfer events are fired during file transfer.

The BytesTransferred parameter shows the number of bytes transferred since the beginning of the transfer.

Text contains the portion of the file data being delivered.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
