QGIS Server 3 / WMS: the SLD parameter support has been removed

[qgib]

Author Name: René-Luc ReLuc (@rldhont)
Original Redmine Issue: 19795
Affected QGIS version: 3.0.0
Redmine category:qgis_server

---

With the suppression of the class QgsHttpTransaction, the support of SLD parameter has been removed.

Here is the code:

  // SLD
  QString value = parameters.value( QStringLiteral( "SLD" ) );
  if ( !value.isEmpty() )
  {
    QgsMessageLog::logMessage( QStringLiteral( "http and ftp methods not supported with Qt5." ) );
  }

Also, the stroke width functions don't function for points and linestrings (only for polygon) although the request goes ok to the server.

You can also replicate under Desktop by:

• export a point sld file with a specific stroke-width (30 pixels for example)
• looking at the sld file the stroke width gets exported

<se:SvgParameter name="stroke-width">30</se:SvgParameter>

• importing the sld file ignores the stroke-width to the default (PROBLEM)

Hi Tudor Bărăscu,

Is there an open issue for your comment ?
Is there some tests in QGIS about SLD support ?

Hi René,

Somehow I didn't notice your reply.
Couldn't find any tests or any open issue regarding this.
The server tests are relatively easy to write.. but I cannot add the exact output image as the stroke-width is ignored and I don't know how to capture the exact image (I haven't tried) from Desktop.

I'll try and see if I can output with QGIS Server 2 and create a pull request.

All the best,
Tudor

Pull request with SLD import fix + test at #7961
The server now outputs correctly for Point and Polygon but for line SLD's it outputs nothing.
I'll try and replicate in a test with the help of the 2.18 server.
