WSClient Class

Properties   Methods   Events   Config Settings   Errors  

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

Syntax

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 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 (WSClient Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetAcceptData();
int SetAcceptData(int bAcceptData);

Unicode (Windows)
BOOL GetAcceptData();
INT SetAcceptData(BOOL bAcceptData);

int ipworksssl_wsclient_getacceptdata(void* lpObj);
int ipworksssl_wsclient_setacceptdata(void* lpObj, int bAcceptData);

bool GetAcceptData();
int SetAcceptData(bool bAcceptData);

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 (WSClient Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetAuthorization();
int SetAuthorization(const char* lpszAuthorization);

Unicode (Windows)
LPWSTR GetAuthorization();
INT SetAuthorization(LPCWSTR lpszAuthorization);

char* ipworksssl_wsclient_getauthorization(void* lpObj);
int ipworksssl_wsclient_setauthorization(void* lpObj, const char* lpszAuthorization);

QString GetAuthorization();
int SetAuthorization(QString qsAuthorization);

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 (WSClient Class)

The authentication scheme to use when server authentication is required.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetAuthScheme();
int SetAuthScheme(int iAuthScheme);

Unicode (Windows)
INT GetAuthScheme();
INT SetAuthScheme(INT iAuthScheme);

AUTH_BASIC(0), 
AUTH_DIGEST(1), 
AUTH_PROPRIETARY(2),

AUTH_NTLM(4), 
AUTH_NEGOTIATE(5), 
AUTH_OAUTH(6)

int ipworksssl_wsclient_getauthscheme(void* lpObj);
int ipworksssl_wsclient_setauthscheme(void* lpObj, int iAuthScheme);

int GetAuthScheme();
int SetAuthScheme(int iAuthScheme);

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

DataToSend Property (WSClient Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SetDataToSend(const char* lpDataToSend, int lenDataToSend);

Unicode (Windows)
INT SetDataToSend(LPCSTR lpDataToSend, INT lenDataToSend);

int ipworksssl_wsclient_setdatatosend(void* lpObj, const char* lpDataToSend, int lenDataToSend);

int SetDataToSend(QByteArray qbaDataToSend);

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

Data Type

String

FollowRedirects Property (WSClient Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetFollowRedirects();
int SetFollowRedirects(int iFollowRedirects);

Unicode (Windows)
INT GetFollowRedirects();
INT SetFollowRedirects(INT iFollowRedirects);

FR_NEVER(0), 
FR_ALWAYS(1), 
FR_SAME_SCHEME(2)

int ipworksssl_wsclient_getfollowredirects(void* lpObj);
int ipworksssl_wsclient_setfollowredirects(void* lpObj, int iFollowRedirects);

int GetFollowRedirects();
int SetFollowRedirects(int iFollowRedirects);

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 (WSClient Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetLineMode();

Unicode (Windows)
BOOL GetLineMode();

int ipworksssl_wsclient_getlinemode(void* lpObj);

bool GetLineMode();

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 (WSClient Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost);

Unicode (Windows)
LPWSTR GetLocalHost();
INT SetLocalHost(LPCWSTR lpszLocalHost);

char* ipworksssl_wsclient_getlocalhost(void* lpObj);
int ipworksssl_wsclient_setlocalhost(void* lpObj, const char* lpszLocalHost);

QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);

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 (WSClient Class)

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

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetLocalPort();
int SetLocalPort(int iLocalPort);

Unicode (Windows)
INT GetLocalPort();
INT SetLocalPort(INT iLocalPort);

int ipworksssl_wsclient_getlocalport(void* lpObj);
int ipworksssl_wsclient_setlocalport(void* lpObj, int iLocalPort);

int GetLocalPort();
int SetLocalPort(int iLocalPort);

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

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.

int ipworksssl_wsclient_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

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.

Data Type

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.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

public:
  int DataFormat();

  const QByteArray &Text();

  bool EOM();

  bool EOL();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void DataIn(WSClientDataInEventParams *e);

// Or, subclass WSClient and override this emitter function.
virtual int FireDataIn(WSClientDataInEventParams *e) {...}

Remarks

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

The incoming data is provided through the Text parameter.

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

The EOM parameter stands for End Of Message. By default the class will fire the DataIn event as data is 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 LineMode is false, EOL will always be false. When LineMode is true, EOL will be True if the DataIn event fired because an EOL was received, and false if the DataIn event fired because MaxLineLength was reached.

Disconnected Event (WSClient Class)

This event is fired when a connection is closed.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireDisconnected(WSClientDisconnectedEventParams *e);

class WSClientDisconnectedEventParams {
public:
  int StatusCode();

  const QString &Description();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Disconnected(WSClientDisconnectedEventParams *e);

// Or, subclass WSClient and override this emitter function.
virtual int FireDisconnected(WSClientDisconnectedEventParams *e) {...}

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error.

Please refer to the Error Codes section for more information.

void SetCookie(WSClientSetCookieEventParams *e);

// Or, subclass WSClient and override this emitter function.
virtual int FireSetCookie(WSClientSetCookieEventParams *e) {...}

Remarks

The SetCookie 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 (URLServer) 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 (URLPath) 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.

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.

SSLStatus Event (WSClient Class)

Shows the progress of the secure connection.

Trappable Errors (WSClient Class)

Error Handling (C++)

Call the GetLastErrorCode() method to obtain the last called method's result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. Known error codes are listed below. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
