WSClient Class

Properties   Methods   Events   Config Settings   Errors  

The WSClient class is used to establish a WebSocket connection to a server.

Syntax

class ipworks.WSClient

Remarks

The WSClient class provides a simple way to establish a WebSocket connection to a server. The server must support the WebSocket protocol. After the connection is established, data can be sent and received.

To begin, call the connect method. After the connection is established, you can send and receive data in a variety of ways. To send data, you may call send, send_file, or send_text. Data are received through the on_data_in event.

The class supports both plaintext (ws://) and Secure Sockets Layer (wss://) connections.

accept_data Property

This property indicates whether data reception is currently enabled.

Syntax

def get_accept_data() -> bool: ...

accept_data = property(get_accept_data, None)

Default Value

TRUE

Remarks

This property indicates whether data reception is currently enabled. When False, data reception is disabled and the on_data_in event will not fire. Use the pause_data and process_data methods to pause and resume data reception.

This property is read-only.

authorization Property

This property includes the Authorization string to be sent to the server.

Syntax

def get_authorization() -> str: ...
def set_authorization(value: str) -> None: ...

authorization = property(get_authorization, set_authorization)

Default Value

""

Remarks

If the authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP class can be extended with other security schemes in addition to the authorization schemes already implemented by the class.

The auth_scheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time user and password are set, they are Base64 encoded, and the result is put in the authorization property in the form "Basic [encoded-user-password]".

auth_scheme Property

This property specifies the authentication scheme to use when server authentication is required.

Syntax

def get_auth_scheme() -> int: ...
def set_auth_scheme(value: int) -> None: ...

auth_scheme = property(get_auth_scheme, set_auth_scheme)

Default Value

0

Remarks

This property will tell the class which type of authorization to perform when the user and password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the user and password properties are set, the class will attempt HTTP Basic Authentication. If auth_scheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.

If auth_scheme is set to authProprietary (2), then the authorization token must be supplied through the authorization property.

If auth_scheme is set to authOAuth (6), then the authorization string must be supplied through the authorization property.

Note: If you set the authorization property and auth_scheme is not authProprietary or authOAuth, then the auth_scheme will be set automatically to authProprietary (2) by the class.

For security, changing the value of this property will cause the class to clear the values of user, password, and Authorization.

bytes_sent Property

This property includes the number of bytes actually sent after a call to the SendBytes method.

Syntax

def get_bytes_sent() -> int: ...

bytes_sent = property(get_bytes_sent, None)

Default Value

0

Remarks

This property indicates how many bytes were sent after the last call to send_bytes. Please check the send_bytes method for more information.

Note: that bytes_sent will always return 0 when the class is operating in synchronous mode (i.e., the timeout property is set to a positive value.)

This property is read-only.

compression_method Property

This property determines whether the class will request that data in the connection be compressed.

Syntax

def get_compression_method() -> int: ...

Default Value

0

Remarks

The type of firewall to connect through. The applicable values are as follows:

firewall_host Property

The name or IP address of the firewall (optional).

Syntax

def get_firewall_host() -> str: ...
def set_firewall_host(value: str) -> None: ...

firewall_host = property(get_firewall_host, set_firewall_host)

Default Value

""

Remarks

The name or IP address of the firewall (optional). If a firewall_host is given, the requested connections will be authenticated through the specified firewall when connecting.

If this property is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, the class fails with an error.

firewall_password Property

A password if authentication is to be used when connecting through the firewall.

Syntax

def get_firewall_password() -> str: ...
def set_firewall_password(value: str) -> None: ...

firewall_password = property(get_firewall_password, set_firewall_password)

Default Value

""

Remarks

A password if authentication is to be used when connecting through the firewall. If firewall_host is specified, the firewall_user and firewall_password properties are used to connect and authenticate to the given firewall. If the authentication fails, the class fails with an error.

firewall_port Property

The Transmission Control Protocol (TCP) port for the firewall Host .

Syntax

def get_firewall_port() -> int: ...
def set_firewall_port(value: int) -> None: ...

firewall_port = property(get_firewall_port, set_firewall_port)

Default Value

0

Remarks

The Transmission Control Protocol (TCP) port for the firewall firewall_host. See the description of the firewall_host property for details.

Note: This property is set automatically when firewall_type is set to a valid value. See the description of the firewall_type property for details.

firewall_user Property

A username if authentication is to be used when connecting through a firewall.

Syntax

def get_firewall_user() -> str: ...
def set_firewall_user(value: str) -> None: ...

firewall_user = property(get_firewall_user, set_firewall_user)

Default Value

""

Remarks

A username if authentication is to be used when connecting through a firewall. If firewall_host is specified, this property and the firewall_password property are used to connect and authenticate to the given Firewall. If the authentication fails, the class fails with an error.

follow_redirects Property

Determines what happens when the server issues a redirect.

Syntax

def get_follow_redirects() -> int: ...
def set_follow_redirects(value: int) -> None: ...

follow_redirects = property(get_follow_redirects, set_follow_redirects)

Default Value

0

Remarks

This property determines what happens when the server issues a redirect. Normally, the class returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new url for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new url is retrieved automatically only if the url_scheme is the same; otherwise, the class fails with an error.

Note: Following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, user and password are also reset to empty. If, however, this property is set to frAlways (1), the same credentials are used to connect to the new server.

A on_redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the on_redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the class fails with an error instead.

line_mode Property

This property indicates whether the class will fire DataIn for each line received.

Syntax

def get_line_mode() -> bool: ...

line_mode = property(get_line_mode, None)

Default Value

FALSE

Remarks

When line_mode is False (default), the component will fire the on_data_in event once for each message received from the server. When line_mode is True, the component will instead fire on_data_in for each line of data received. The maximum length of a line can be controlled by the MaxLineLength configuration setting.

Note: This is a read-only property and should be set through the change_line_mode method.

This property is read-only.

local_host Property

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

def get_local_host() -> str: ...
def set_local_host(value: str) -> None: ...

local_host = property(get_local_host, set_local_host)

Default Value

""

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the local_host property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: local_host is not persistent. You must always set it in code, and never in the property window.

local_port Property

The TCP port in the local host where the class binds.

Syntax

def get_local_port() -> int: ...
def set_local_port(value: int) -> None: ...

local_port = property(get_local_port, set_local_port)

Default Value

0

Remarks

This property must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this property to 0 (default) enables the system to choose an open port at random. The chosen port will be returned by the local_port property after the connection is established.

local_port cannot be changed once a connection is made. Any attempt to set this property when a connection is active will generate an error.

This property is useful when trying to connect to services that require a trusted port on the client side.

origin Property

This property includes the Origin header field value.

Syntax

def get_origin() -> str: ...
def set_origin(value: str) -> None: ...

origin = property(get_origin, set_origin)

Default Value

""

Remarks

If specified, the class will include an Origin HTTP header in the connection request with the value provided. Servers may use this value to validate requests. Servers may reject requests depending on the value provided.

A typical value that would be set is in the following form: "http://example.com".

other_headers Property

Other headers as determined by the user (optional).

Syntax

def get_other_headers() -> str: ...
def set_other_headers(value: str) -> None: ...

other_headers = property(get_other_headers, set_other_headers)

Default Value

""

Remarks

This property can be set to a string of headers to be appended to the HTTP request headers created from other properties like content_type and from_.

The headers must follow the format Header: Value as described in the HTTP specifications. Header lines should be separated by CRLF ("\r\n") .

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for extending the functionality of the class beyond what is provided.

parsed_header_count Property

The number of records in the ParsedHeader arrays.

Syntax

def get_parsed_header_count() -> int: ...

parsed_header_count = property(get_parsed_header_count, None)

Default Value

0

Remarks

This property controls the size of the following arrays:

• parsed_header_field
• parsed_header_value

The array indices start at 0 and end at parsed_header_count - 1.

This property is read-only.

parsed_header_field Property

This property contains the name of the HTTP header (this is the same case as it is delivered).

Syntax

def get_parsed_header_field(parsed_header_index: int) -> str: ...

Default Value

""

Remarks

This property contains the name of the HTTP Header (this is the same case as it is delivered).

The parsed_header_index parameter specifies the index of the item in the array. The size of the array is controlled by the parsed_header_count property.

This property is read-only.

parsed_header_value Property

This property contains the header contents.

Syntax

def get_parsed_header_value(parsed_header_index: int) -> str: ...

Default Value

""

Remarks

This property contains the Header contents.

password Property

This property includes a password if authentication is to be used.

Syntax

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

password = property(get_password, set_password)

Default Value

""

Remarks

This property contains a password if authentication is to be used. If auth_scheme is set to HTTP Basic Authentication, the user and password are Base64 encoded and the result is put in the Authorization configuration setting in the form "Basic [encoded-user-password]".

If auth_scheme is set to HTTP Digest Authentication, the user and password properties are used to respond to the HTTP Digest Authentication challenge from the server.

If auth_scheme is set to NTLM, NTLM authentication will be attempted. If auth_scheme is set to NTLM and user and password are empty, the class will attempt to authenticate using the current user's credentials.

proxy_auth_scheme Property

The type of authorization to perform when connecting to the proxy.

Syntax

def get_proxy_auth_scheme() -> int: ...
def set_proxy_auth_scheme(value: int) -> None: ...

proxy_auth_scheme = property(get_proxy_auth_scheme, set_proxy_auth_scheme)

Default Value

0

Remarks

The type of authorization to perform when connecting to the proxy. This is used only when the proxy_user and proxy_password properties are set.

proxy_auth_scheme should be set to authNone (3) when no authentication is expected.

By default, proxy_auth_scheme is authBasic (0), and if the proxy_user and proxy_password properties are set, the class will attempt basic authentication.

If proxy_auth_scheme is set to authDigest (1), digest authentication will be attempted instead.

If proxy_auth_scheme is set to authProprietary (2), then the authorization token will not be generated by the class. Look at the configuration file for the class being used to find more information about manually setting this token.

If proxy_auth_scheme is set to authNtlm (4), NTLM authentication will be used.

For security reasons, setting this property will clear the values of proxy_user and proxy_password.

proxy_auto_detect Property

Whether to automatically detect and use proxy system settings, if available.

Syntax

def get_proxy_auto_detect() -> bool: ...
def set_proxy_auto_detect(value: bool) -> None: ...

proxy_server Property

If a proxy Server is given, then the HTTP request is sent to the proxy instead of the server otherwise specified.

Syntax

def get_proxy_server() -> str: ...
def set_proxy_server(value: str) -> None: ...

proxy_server = property(get_proxy_server, set_proxy_server)

Default Value

""

Remarks

If a proxy proxy_server is given, then the HTTP request is sent to the proxy instead of the server otherwise specified.

If the proxy_server property is set to a domain name, a DNS request is initiated. Upon successful termination of the request, the proxy_server property is set to the corresponding address. If the search is not successful, an error is returned.

timeout Property

This property includes the 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 return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.

If timeout is set to a positive value, data is sent in a blocking manner and the class will wait for the operation to complete before returning control. The class will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of timeout seconds.

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.

Note: By default, all timeouts are inactivity timeouts, that is, 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.

change_line_mode Method

This method controls whether the class will fire DataIn for each line received.

Syntax

def change_line_mode(line_mode: bool) -> None: ...

Remarks

When line_mode is set to False (default), the component will fire the on_data_in event once for each message received from the server. When line_mode is set to True, the component will instead fire on_data_in for each line of data received. The maximum length of a line can be controlled by the MaxLineLength configuration setting.

Note: This method is offered as a convenience feature and has no effect on the behavior of the WebSocket protocol.

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.

Remarks

The on_data_in event provides the data received from the remote host.

The incoming data are provided through the Text parameter.

The DataFormat parameter identifies the encoding (if any) of the data. Possible value are as follows:

The EOM parameter stands for End of Message. By default, the class will fire the on_data_in event as data are received. Larger messages will be fragmented and will cause the event to fire multiple times. When EOM is True within the event, this indicates the current fragment is also the final fragment of the message. The class may also be configured to buffer the message internally until the complete message is received. To enable this, set BufferMessage to True.

The EOL parameter stands for End of Line. When line_mode is False, EOL will always be False. When line_mode is True, EOL will be True if the on_data_in event fired because an EOL was received and will be False if the on_data_in event fired because MaxLineLength was reached.

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information including the URL, HTTP version, and connection status details.

The value 2 (Verbose) logs additional information about the initial HTTP request.

The value 3 (Debug) logs additional debug information (if available).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "Error"
• "Verbose"
• "Debug"

on_ping Event

This event is fired when a ping request or response is received.

Syntax

class WSClientPingEventParams(object):
  @property
  def payload() -> bytes: ...

  @property
  def response() -> bool: ...

# In class WSClient:
@property
def on_ping() -> Callable[[WSClientPingEventParams], None]: ...
@on_ping.setter
def on_ping(event_hook: Callable[[WSClientPingEventParams], None]) -> None: ...

Remarks

This event fires when a ping request or response is received. This event is informational only. When the class receives a ping request, it will automatically reply with a pong.

Payload holds the payload of the request, if any.

Response is True if the incoming packet is a ping response. If the incoming packet is a ping request, this is False.

on_ready_to_send Event

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

Syntax

class WSClientReadyToSendEventParams(object):
# In class WSClient:
@property
def on_ready_to_send() -> Callable[[WSClientReadyToSendEventParams], None]: ...
@on_ready_to_send.setter
def on_ready_to_send(event_hook: Callable[[WSClientReadyToSendEventParams], 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 send_bytes. This event also is fired immediately after a connection to the remote host is established.

on_redirect Event

Fired when a redirection is received from the server.

Syntax

class WSClientRedirectEventParams(object):
  @property
  def location() -> str: ...

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

# In class WSClient:
@property
def on_redirect() -> Callable[[WSClientRedirectEventParams], None]: ...
@on_redirect.setter
def on_redirect(event_hook: Callable[[WSClientRedirectEventParams], None]) -> None: ...

Remarks

This event is fired in cases in which the client can decide whether or not to continue with the redirection process. The Accept parameter is always True by default, but if you do not want to follow the redirection, Accept may be set to False, in which case the class fails with an error. Location is the location to which the client is being redirected. Further control over redirection is provided in the follow_redirects property.

on_set_cookie Event

Fired for every cookie set by the server.

Syntax

class WSClientSetCookieEventParams(object):
  @property
  def name() -> str: ...

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

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

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

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

  @property
  def secure() -> bool: ...

# In class WSClient:
@property
def on_set_cookie() -> Callable[[WSClientSetCookieEventParams], None]: ...
@on_set_cookie.setter
def on_set_cookie(event_hook: Callable[[WSClientSetCookieEventParams], None]) -> None: ...

Remarks

This event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (url_server) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (url_path) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class WSClientSSLServerAuthenticationEventParams(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 WSClient:
@property
def on_ssl_server_authentication() -> Callable[[WSClientSSLServerAuthenticationEventParams], None]: ...
@on_ssl_server_authentication.setter
def on_ssl_server_authentication(event_hook: Callable[[WSClientSSLServerAuthenticationEventParams], None]) -> None: ...

Remarks

During this event, the client can decide whether or not to continue with the connection process. 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 or not to continue.

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

Fired when secure connection progress messages are available.

Syntax

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

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

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
