Re: [QGIS-Developer] QGIS WebSocket

[Nathan Woodrow via QGIS-Developer]

Hi,

You can use the QWebSocket (https://doc.qt.io/qt-6/qwebsocket.html) object
to do this.  Ships with Qt and QGIS.  I did some R with it a while ago
and it worked well.

Hi dev folks,

I am working on creating a connection between my exp plugin and server via
a WebSocket connection for data transferring. So my question is about
whether QGIS has a WebSocket feature/ connect algorithm.

Thanks

Re: [QGIS-Developer] PyQGIS read project from postgresql database

[Alexandre Neto via QGIS-Developer]

Hi,

Actually, after I turned off the computer, I saw the fileName() method in 
documentation.

I tried it and I realised that both my password and project name needed percent 
encoding some characters.

So I have parsed my uri string with urllob.parse.quote to make it work 
correctly.

Not sure if there's a more convenient way to do it.

Thanks for the help German.
