<p class="MsoNormal"><span>Hi,<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>I think I might have just spotted the issue with my code.
<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>If you do quir.encodedUri() you get an error in version 3.4 because it is expecting a string but encodedUri returns a ByteArray. If you wrap it in the str() function you get a result because the
result in now a string however it is a string which has b’ a the front and a trailing ‘ at the end.
<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>I believe the trailing ‘ is being taken literally and the resulting getCapabilities statement is for
<a href="https://domain.name/wms'?request=GetCapabilities" target="_blank">https://domain.name/wms’?request=GetCapabilities</a><u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>If you use quir.uri() it doesn’t work and neither does quir.uri(False) so what should I be using there or should the QgsRasterLayer function just be accepting a ByteArray or String?<u></u><u></u></span></p>

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal"><span>Hi,<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>I couldn’t get it to work with “authMgr = QgsAuthManager.instance()” so following the comment at the top of (</span><a href="https://qgis.org/pyqgis/3.4/core/QgsAuthManager.html" target="_blank">https://qgis.org/pyqgis/3.4/core/QgsAuthManager.html</a><span>)
I used “authMgr = QgsApplication.authManager()” instead.<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>I changed “authMgr.authenticationDbPath()” to “authMgr.authenticationDatabasePath()”.<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>I also changed “QgsDataSourceURI()” to “QgsDataSourceUri()”.<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>p_config.setConfig("certpath", "path/to/alice-cert.pem" ))<u></u><u></u></span></p>
<p class="MsoNormal"><span>p_config.setConfig("keypath", "path/to/alice-key.pem" ))<u></u><u></u></span></p>
<p class="MsoNormal"><span>There are extra brackets on the lines above but clearly those are just typos.
<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>Finally the line “rlayer = QgsRasterLayer(quri.encodedUri(), 'states', 'wms')” only ran if I put in “rlayer = QgsRasterLayer(str(quri.encodedUri()), 'states', 'wms')”.<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>That is the issue though; whilst the line above runs in QGIS it doesn’t appear to actually be authenticating on the GetCapabilities request. This maybe because our server uses pre-authentication
because it is a GeoServer which is set to HIDE (</span><a href="https://docs.geoserver.org/latest/en/user/security/webadmin/data.html#catalog-mode" target="_blank">https://docs.geoserver.org/latest/en/user/security/webadmin/data.html#catalog-mode</a>)<span>.
<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>As far as I can tell there is no concept of that in QGIS so in effect I believe QGIS would not support HIDE mode GeoServers unless you are using some sort of token based authentication as it will
send a number of requests without the correct authentication settings. I’ve been investigating a work around given that this process is aimed at connections via our network only but perhaps I’ve missed something obvious or the use of str() in the statement
above is simply preventing the authentication manager from expanding the auth credentials at the last minute?
<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>I’ll go do a quick update for the brackets and I can update the other lines once others have confirmed my interpretations are correct; they compiled but that doesn’t mean I got them right!<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>

<p class="MsoNormal">The line “rlayer = QgsRasterLayer(quri.encodedUri(), 'states', 'wms')” was resulting in an unexpected type error as encodedUri returns a QByteArray rather than a string but I just
