Detailed Description

network access manager for QGIS

This class implements the QGIS network access manager. It's a singleton that can be used across QGIS.

Plugins can insert proxy factories and thereby redirect requests to individual proxies.

If no proxy factories are there or none returns a proxy for an URL a fallback proxy can be set. There's also a exclude list that defines URLs that the fallback proxy should not be used for, then no proxy will be used.

Member Function Documentation

◆ abortAuthBrowser()

void QgsNetworkAccessManager::abortAuthBrowser ( )

Abort any outstanding external browser login request.

Note: Background threads will listen to aborted browser request signals from the network manager on the main thread.

Since: QGIS 3.20

Definition at line 561 of file qgsnetworkaccessmanager.cpp.

◆ authBrowserAborted

void QgsNetworkAccessManager::authBrowserAborted ( )

signal

Emitted when external browser logins are to be aborted.

Since: QGIS 3.20

◆ blockingGet()

QgsNetworkReplyContent QgsNetworkAccessManager::blockingGet	(	QNetworkRequest &	request,
		const QString &	authCfg = `QString()`,
		bool	forceRefresh = `false`,
		QgsFeedback *	feedback = `nullptr`
	)

static

Posts a GET request to obtain the contents of the target request and returns a new QgsNetworkReplyContent object for reading.

The current thread will be blocked until the request is returned.

This method is safe to call in either the main thread or a worker thread.

If forceRefresh is false then previously cached replies may be used for the request. If it is set to true then a new query is always performed.

If an authCfg has been specified, then that authentication configuration required will automatically be applied to request. There is no need to manually apply the authentication to the request prior to calling this method.

The optional feedback argument can be used to abort ongoing requests.

The contents of the reply will be returned after the request is completed or an error occurs.

◆ downloadProgress

void QgsNetworkAccessManager::downloadProgress	(	int	requestId,
		qint64	bytesReceived,
		qint64	bytesTotal
	)

signal

Emitted when a network reply receives a progress report.

The requestId argument reflects the unique ID identifying the original request which the progress report relates to.

The bytesReceived parameter indicates the number of bytes received, while bytesTotal indicates the total number of bytes expected to be downloaded. If the number of bytes to be downloaded is not known, bytesTotal will be -1.

This signal is propagated to the main thread QgsNetworkAccessManager instance, so it is necessary only to connect to the main thread's signal in order to receive notifications about requests created in any thread.

Since: QGIS 3.6

◆ excludeList()

QStringList QgsNetworkAccessManager::excludeList ( ) const

Returns the proxy exclude list.

This list consists of the beginning of URL strings which will not use the fallback proxy.

Since: QGIS 3.6

◆ insertProxyFactory()

void QgsNetworkAccessManager::insertProxyFactory ( QNetworkProxyFactory * factory )

Inserts a factory into the proxy factories list.

Ownership of factory is transferred to the manager.

See also: removeProxyFactory(); proxyFactories()

Definition at line 237 of file qgsnetworkaccessmanager.cpp.

◆ instance()

QgsNetworkAccessManager * QgsNetworkAccessManager::instance ( Qt::ConnectionType connectionType = Qt::BlockingQueuedConnection )

static

Returns a pointer to the active QgsNetworkAccessManager for the current thread.

With the connectionType parameter it is possible to setup the default connection type that is used to handle signals that might require user interaction and therefore need to be handled on the main thread. See in-depth discussion below.

Parameters

connectionType In most cases the default of using a Qt::BlockingQueuedConnection is ok, to make a background thread wait for the main thread to answer such a request is fine and anything else is dangerous. However, in case the request was started on the main thread, one should execute a local event loop in a helper thread and freeze the main thread for the duration of the download. In this case, if an authentication request is sent from the background thread network access manager, the background thread should be blocked, the main thread be woken up, processEvents() executed once, the main thread frozen again and the background thread continued.

Definition at line 197 of file qgsnetworkaccessmanager.cpp.

◆ noProxyList()

QStringList QgsNetworkAccessManager::noProxyList ( ) const

Returns the no proxy list.

This list consists of the beginning of URL strings which will not use any proxy at all

QString QgsNetworkAccessManager::setReplyPreprocessor ( const std::function< void(const QNetworkRequest &, QNetworkReply *)> & processor )

static

Sets a reply pre-processor function, which allows manipulation of QNetworkReply objects after they are created (but before they are fetched).

The processor function takes a QNetworkRequest request and a QNetworkReply as arguments, and can connect to QNetworkReply signals directly as desired.

Returns: An auto-generated string uniquely identifying the preprocessor, which can later be used to remove the preprocessor (via a call to removeReplyPreprocessor()).

See also: removeReplyPreprocessor()

Since: QGIS 3.26
