With recent changes in QgsNetworkAccessManager this should be safe to resurrect (fingers crossed!). Also simplify code a lot, because now QgsNetworkAccessManager handles waking the worker thread after the auth request is handled. Add a lot more tests

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.

|
|
%Docstring
|
|
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.
|
|
|
|
:param 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.

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

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

this method.
