WebUpload Class

Properties   Methods   Events   Config Settings   Errors  

The WebUpload Class is used to upload files to RFC1867-compliant web servers.

Syntax

WebUpload

Remarks

The WebUpload Class supports both plaintext and SSL/TLS connections. When connecting over SSL/TLS the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL related settings are also supported via the Config method.

To use the class as a file upload client, provide the file names (paths) in the FileVars properties and optional form variables in the FormVars properties.

Then, set the URL property to the address of the page or script that accepts the files, and call the Upload method. Alternatively you can call the UploadTo method with URL as a parameter.

The UploadProgress event is fired during upload which shows the progress of the upload. The Transfer event shows the server response (normally an HTML page).

Accept Property (WebUpload Class)

This property includes a list of acceptable MIME types for the request.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetAccept();
int SetAccept(const char* lpszAccept);

Unicode (Windows)
LPWSTR GetAccept();
INT SetAccept(LPCWSTR lpszAccept);

char* ipworks_webupload_getaccept(void* lpObj);
int ipworks_webupload_setaccept(void* lpObj, const char* lpszAccept);

QString GetAccept();
int SetAccept(QString qsAccept);

Default Value

""

Remarks

If this property contains a nonempty string, an HTTP Accept header is added to the request.

The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.

Data Type

String

Authorization Property (WebUpload 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);

int ipworks_webupload_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 (WebUpload 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_NONE(3), 
AUTH_NTLM(4), 
AUTH_NEGOTIATE(5), 
AUTH_OAUTH(6)

int ipworks_webupload_getauthscheme(void* lpObj);
int ipworks_webupload_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.

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.

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 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.

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* ipworks_webupload_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

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.

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.

virtual int FireSetCookie(WebUploadSetCookieEventParams *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.

// Or, subclass WebUpload and override this emitter function.
virtual int FireSSLServerAuthentication(WebUploadSSLServerAuthenticationEventParams *e) {...}

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 (WebUpload Class)

Fired when secure connection progress messages are available.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLStatus(WebUploadSSLStatusEventParams *e);

typedef struct {
  const char *Message;
  int reserved;
} WebUploadSSLStatusEventParams;


Unicode (Windows)
virtual INT FireSSLStatus(WebUploadSSLStatusEventParams *e);

typedef struct {
  LPCWSTR Message;
  INT reserved;
} WebUploadSSLStatusEventParams;

#define EID_WEBUPLOAD_SSLSTATUS 11

virtual INT IPWORKS_CALL FireSSLStatus(LPSTR &lpszMessage);

class WebUploadSSLStatusEventParams {
public:

  void SetEventRetVal(int iRetVal);
};

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

// Or, subclass WebUpload and override this emitter function.
virtual int FireSSLStatus(WebUploadSSLStatusEventParams *e) {...}

Remarks

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

StartTransfer Event (WebUpload Class)

Fired when a document starts transferring (after the headers).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireStartTransfer(WebUploadStartTransferEventParams *e);

typedef struct {
  int Direction;
  int reserved;
} WebUploadStartTransferEventParams;


Unicode (Windows)
virtual INT FireStartTransfer(WebUploadStartTransferEventParams *e);

typedef struct {
  INT Direction;
  INT reserved;
} WebUploadStartTransferEventParams;

#define EID_WEBUPLOAD_STARTTRANSFER 12

virtual INT IPWORKS_CALL FireStartTransfer(INT &iDirection);

class WebUploadStartTransferEventParams {
public:
  int Direction();

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

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

// Or, subclass WebUpload and override this emitter function.
virtual int FireStartTransfer(WebUploadStartTransferEventParams *e) {...}

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

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

Status Event (WebUpload Class)

This event is fired when the HTTP status line is received from the server.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireStatus(WebUploadStatusEventParams *e);

typedef struct {
  const char *HTTPVersion;
  int StatusCode;
  const char *Description;
  int reserved;
} WebUploadStatusEventParams;


Unicode (Windows)
virtual INT FireStatus(WebUploadStatusEventParams *e);

typedef struct {
  LPCWSTR HTTPVersion;
  INT StatusCode;
  LPCWSTR Description;
  INT reserved;
} WebUploadStatusEventParams;

#define EID_WEBUPLOAD_STATUS 13

virtual INT IPWORKS_CALL FireStatus(LPSTR &lpszHTTPVersion, INT &iStatusCode, LPSTR &lpszDescription);

class WebUploadStatusEventParams {
public:
  const QString &HTTPVersion();

  int StatusCode();

  const QString &Description();

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

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

// Or, subclass WebUpload and override this emitter function.
virtual int FireStatus(WebUploadStatusEventParams *e) {...}

Remarks

HTTPVersion is a string containing the HTTP version string as returned from the server (e.g., "1.1").

StatusCode contains the HTTP status code (e.g., 200), and Description the associated message returned by the server (e.g., "OK").

Transfer Event (WebUpload Class)

This event is fired while a document transfers (delivers document).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireTransfer(WebUploadTransferEventParams *e);

typedef struct {
  int Direction;
  int64 BytesTransferred;
  int PercentDone;
  const char *Text;
  int lenText;
  int reserved;
} WebUploadTransferEventParams;


Unicode (Windows)
virtual INT FireTransfer(WebUploadTransferEventParams *e);

typedef struct {
  INT Direction;
  LONG64 BytesTransferred;
  INT PercentDone;
  LPCSTR Text;
  INT lenText;
  INT reserved;
} WebUploadTransferEventParams;

#define EID_WEBUPLOAD_TRANSFER 14

virtual INT IPWORKS_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText);

class WebUploadTransferEventParams {
public:
  int Direction();

  qint64 BytesTransferred();

  int PercentDone();

  const QByteArray &Text();

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

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

// Or, subclass WebUpload and override this emitter function.
virtual int FireTransfer(WebUploadTransferEventParams *e) {...}

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

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.

UploadProgress Event (WebUpload Class)

Fired while the class is uploading files to the URL .

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireUploadProgress(WebUploadUploadProgressEventParams *e);

typedef struct {
  int PercentDone;
  int reserved;
} WebUploadUploadProgressEventParams;


Unicode (Windows)
virtual INT FireUploadProgress(WebUploadUploadProgressEventParams *e);

typedef struct {
  INT PercentDone;
  INT reserved;
} WebUploadUploadProgressEventParams;

#define EID_WEBUPLOAD_UPLOADPROGRESS 15

virtual INT IPWORKS_CALL FireUploadProgress(INT &iPercentDone);

class WebUploadUploadProgressEventParams {
public:
  int PercentDone();

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

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

// Or, subclass WebUpload and override this emitter function.
virtual int FireUploadProgress(WebUploadUploadProgressEventParams *e) {...}

Remarks

The PercentDone parameter shows the progress of the upload. The event is fired at least once at the beginning of the transfer, and once at the end of the transfer. The respective values for PercentDone are 0 and 100.
