Detailed Description

HTTP request/response manager that is redirect-aware.

This class extends the Qt QHttp concept by being able to recognise and respond to redirection responses (e.g. HTTP code 302)

Member Function Documentation

void QgsHttpTransaction::abort ( )

slot

Aborts the current transaction.

Definition at line 565 of file qgshttptransaction.cpp.

bool QgsHttpTransaction::applyProxySettings	(	QHttp &	http,

static

Apply proxy settings from QSettings to a http object.

Returns: true if proxy settings was applied, false else

Definition at line 437 of file qgshttptransaction.cpp.

QString QgsHttpTransaction::errorString ( )

If an operation returns 0 (e.g.

getSynchronously()), this function returns the text of the error associated with the failure. Interactive users of this provider can then, for example, call a QMessageBox to display the contents.

Definition at line 503 of file qgshttptransaction.cpp.

void QgsHttpTransaction::getAsynchronously ( )

Definition at line 86 of file qgshttptransaction.cpp.

bool QgsHttpTransaction::getSynchronously	(	QByteArray &	respondedContent,
		int	redirections = `0`,
		const QByteArray *	postData = `0`
	)

Gets the response synchronously.

Note that signals will still be emitted while in this function.

The function returns false if there is an error while getting the response.

Parameters

[out]	respondedContent	is replaced with the new content.
[in]	redirections	is used to measure how many http redirections we've been through. Clients typically don't need to set this.
	postData	data to send with the http message. This is only used for HTTP POST. If 0 then the request is done with HTTP GET.

Returns: true in case of success

void QgsHttpTransaction::networkTimedOut ( )

slot

Definition at line 490 of file qgshttptransaction.cpp.
