uri = '''https://vmap0.tiles.osgeo.org/wms/vmap0?LAYERS=basic&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fjpeg&SRS=EPSG%3A4326&BBOX=-90,45,-45,90&WIDTH=256&HEIGHT=256 '''
layer = QgsRasterLayer(uri, "RESA", "WMS")
if layer.isValid():
    pass
else:
    print('error')

The result is 'error'.This does not meet my expectations of adding an HTTPS type WMS service.I tried querying pyQGIS's API, but found nothing. enter image description here

  • Note that you are using `QgsVectorLayer` specifying WFS as the data provider to fetch a **raster** WMS layer. Do you know the difference between WFS and WMS? – Dima Chubarov Jul 13 '22 at 02:31
  • sorry! The question is error.I change it at now. – elephant111 Jul 13 '22 at 02:35
  • I am a python engineer.The basic concepts of GIS are not well understood,However, there is no problem with the scenario I asked, that is, how to use pyQGIS API to call the image data adding WMS class, and the protocol type is HTTPS, we call HTTP without problem – elephant111 Jul 13 '22 at 02:40

    To display a WMS layer you need to instantiate a QgsRasterLayer. – Dima Chubarov Jul 13 '22 at 03:19
  • i change my question and add some pictures to explain my dilemma. – elephant111 Jul 13 '22 at 13:00
