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 set the DataToSend property or call Send, SendFile, or SendText. Data is received via the DataIn event.

The class supports both plain-text (ws://) and SSL (wss://) connections.

AcceptData Property (IPWorksSSL_WSClient Class)

This property enables or disables data reception (the DataIn event).

Object Oriented Interface

public function getAcceptData();


public function setAcceptData($value);

Procedural Interface

ipworksssl_wsclient_get($res, 1 );


ipworksssl_wsclient_set($res, 1, $value );

Default Value

true

Remarks

This property enables or disables data reception (the DataIn event). Setting this property to False, temporarily disables data reception (and the DataIn event). Setting this property to True, reenables data reception.

Note: It is recommended to use the PauseData or ProcessData method instead of setting this property.

This property is not available at design time.

Data Type

Boolean

Authorization Property (IPWorksSSL_WSClient Class)

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

Object Oriented Interface

public function getAuthorization();


public function setAuthorization($value);

Procedural Interface

ipworksssl_wsclient_get($res, 2 );


ipworksssl_wsclient_set($res, 2, $value );

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 AuthScheme 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]".

Data Type

String

AuthScheme Property (IPWorksSSL_WSClient Class)

The authentication scheme to use when server authentication is required.

Object Oriented Interface

public function getAuthScheme();


public function setAuthScheme($value);

Procedural Interface

ipworksssl_wsclient_get($res, 3 );


ipworksssl_wsclient_set($res, 3, $value );

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 AuthScheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.

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

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

Note: If you set the Authorization property and AuthScheme is not authProprietary or authOAuth, then the AuthScheme 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.

Data Type

Integer

BytesSent Property (IPWorksSSL_WSClient Class)

This property includes the number of bytes actually sent after an assignment to DataToSend .

Object Oriented Interface

public function getBytesSent();

Possible values are:

Data Type

Integer

DataToSend Property (IPWorksSSL_WSClient Class)

A string of data to be sent to the remote host.

Object Oriented Interface

public function setDataToSend($value);

Procedural Interface

ipworksssl_wsclient_set($res, 15, $value );

Default Value

''

Remarks

Assigning a string to this property makes the class send the string to the remote host. The Send method provides similar functionality.

When this property is set the class will use the value specified in DataFormat to determine the encoding options.

If the Timeout property is set to 0 the component will behave asynchronously. If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, the operation fails with error 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. . The BytesSent property shows how many bytes were sent (if any). If 0 bytes were sent, then you can wait for the ReadyToSend event before attempting to send data again.

Note: The ReadyToSend event is not fired when part of the data is sent successfully.

This property is write-only and not available at design time.

Data Type

Binary String

This property contains a user name if authentication is to be used connecting through a firewall.

Object Oriented Interface

public function getFirewallUser();


public function setFirewallUser($value);

Procedural Interface

ipworksssl_wsclient_get($res, 21 );


ipworksssl_wsclient_set($res, 21, $value );

Default Value

''

Remarks

This property contains a user name if authentication is to be used connecting through a firewall. If the FirewallHost is specified, this property and FirewallPassword properties are used to connect and authenticate to the given Firewall. If the authentication fails, the class fails with an error.

Data Type

String

FollowRedirects Property (IPWorksSSL_WSClient Class)

This property determines what happens when the server issues a redirect.

Object Oriented Interface

public function getFollowRedirects();


public function setFollowRedirects($value);

Procedural Interface

ipworksssl_wsclient_get($res, 22 );


ipworksssl_wsclient_set($res, 22, $value );

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 URLScheme 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 Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the 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.

Data Type

Integer

LineMode Property (IPWorksSSL_WSClient Class)

Indicates whether the class will fire DataIn for each line received.

Object Oriented Interface

public function getLineMode();

Procedural Interface

ipworksssl_wsclient_get($res, 23 );

Default Value

false

Remarks

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

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

This property is read-only and not available at design time.

Data Type

Boolean

LocalHost Property (IPWorksSSL_WSClient Class)

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

Object Oriented Interface

public function getLocalHost();


public function setLocalHost($value);

Procedural Interface

ipworksssl_wsclient_get($res, 24 );


ipworksssl_wsclient_set($res, 24, $value );

Default Value

''

Remarks

The LocalHost 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost 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 multi-homed hosts (machines with more than one IP interface).

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

Data Type

String

LocalPort Property (IPWorksSSL_WSClient Class)

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

Object Oriented Interface

public function getLocalPort();


public function setLocalPort($value);

Procedural Interface

ipworksssl_wsclient_get($res, 25 );


ipworksssl_wsclient_set($res, 25, $value );

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 LocalPort property after the connection is established.

LocalPort 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 in the client side.

Data Type

Integer

Origin Property (IPWorksSSL_WSClient Class)

The Origin header field value.

Object Oriented Interface

public function getOrigin();

ipworksssl_wsclient_set($res, 27, $value );

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 ContentType 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.

This property is not available at design time.

Data Type

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

Data Type

String

ProxyAuthScheme Property (IPWorksSSL_WSClient Class)

This property is used to tell the class which type of authorization to perform when connecting to the proxy.

Object Oriented Interface

public function getProxyAuthScheme();


public function setProxyAuthScheme($value);

Procedural Interface

ipworksssl_wsclient_get($res, 32 );


ipworksssl_wsclient_set($res, 32, $value );

Default Value

0

Remarks

This property is used to tell the class which type of authorization to perform when connecting to the proxy. This is used only when the ProxyUser and ProxyPassword properties are set.

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

By default, ProxyAuthScheme is authBasic (0), and if the ProxyUser and ProxyPassword properties are set, the component will attempt basic authentication.

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

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

For security reasons, setting this property will clear the values of ProxyUser and ProxyPassword.

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 DoEvents 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.
