Export Format don't appear in Lizmap about qgis-wfsoutputextension

[Gustry]

Can you try a request SERVICE=ATLAS&REQUEST=GETCAPABILITIES to check that the plugin is well installed?
Did you clear the cache of the getcapabilities response?

[Maverick83000]

Hi Gustry,

Thanks for your answer.
The request with "SERVICE=ATLAS&REQUEST=GETCAPABILITIES" don't work:

Service unknown or unsupported

But it works with "SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities"

[Gustry]

The request with "SERVICE=ATLAS&REQUEST=GETCAPABILITIES" don't work:

and

But it works with "SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities"

They are two different requests. You must have the first one working. It means the plugin is not well installed.
Did you put the folder wfsOutputExtension next to the other one? (named like this)

[Maverick83000]

I put the extension folder in the /opt/qgis-server/plugins just near the folder qgis-helloserver

[Maverick83000]

I said something wrong early,
I modified the file /etc/apache2/mods-available/fcgid.conf for adding the QGIS_PLUGINPATH
Maybe should I modified the file /etc/apache2/conf-available/serve-cgi-bin.conf ?

[Glasnost46]

J'ai le même problème avec :

QGIS 3.10.8
Lizmap 3.3.9
QGIS server 3.10.7.1
WFSoutputExtension 1.3.0 ou 1.2.3 (les deux versions ont été testées)
Windows server 2012

Le dossier du plugin est déposé ici :
\OSGeo4W64\apps\qgis-ltr\python\plugins\

Le getCapabilities ne mentionne que les formats de base GeoJson et GML

Je suis preneur d'une piste parce que je n'en ai plus moi même :)

Merci

Take a look at the QGIS Server Log, you can check if the plugin is installed and well loaded.

[Glasnost46]

Thank you for your answer.

Indeed, here is my log :

Thank you

[Gustry]

@Glasnost46 Your problem is quite different.
QGIS Server detected the plugin and tried to load it.
But it fails on the Python API:

ImportError: cannot import name 'QgsServerFilter' from 'qgis.server' (unknown location)

I have never tried to install a QGIS plugin server on Windows.

Did you use https://github.com/NaturalGIS/qgis_server_and_lizmap_on_windows ?
CC @gioman, do you know about installing QGIS Server plugin on Windows?

[Glasnost46]

Thanks for your reply Gustry.
I have use the lizmap website to install all (https://docs.lizmap.com/current/fr/install/windows.html), everything seems to work fine except this plugin. My getcapabilities requests are ok.

[gioman]

CC @gioman, do you know about installing QGIS Server plugin on Windows?

@Gustry I have not tested QGIS Server plugins on Windows, nevertheless it would intersting to do so on a machine where QGIS Server was installed and configured with the "recipe" https://github.com/NaturalGIS/qgis_server_and_lizmap_on_windows @Glasnost46 could you do it?

[Glasnost46]

@Glasnost46 could you do it?

I think my setup is ok, except for this plugin.
This plugin worked on windows2012 in my previous setup with qgis2.8 / lizmap 3.2 / qgisserver

[gioman]

qgisserver

QGIS Server 2 or 3?

[Glasnost46]

qgisserver

QGIS Server 2 or 3?

With QGIS server 2.18.28

[gioman]

QGIS Server 3 was basically rewritten from scratch, so there is a chance that something is not working with plugins on Windows.

[Gustry]

@Glasnost46 In your comment, you are talking about QGIS 3:
#15 (comment)

At the top, we can read

QGIS version: 3.10.8-A Coruña 'A Coruña', d09a4f2388

Where did you get this from?

If you are really running QGIS Server 2 (so you must have QGIS Desktop 2 too !), the AtlasPrint plugin must be an older version maybe like 1.1.0 https://github.com/3liz/qgis-atlasprint/releases That's you got the error "ImportError: cannot import name 'QgsServerFilter' from 'qgis.server' (unknown location)"

From my actual qgis_server.log

Now I'm using qgis server 3.10.7.1 with Qgis 3.10.8 and the plugin doesn't work.
Before, with qgis server 2.18.28 and qgis 2.8 it worked well.

I haven't the atlas plugin in my plugin folder.

Anyway, a conflict between old and new files is quite possible I guess.

Thanks for your help

[Maverick83000]

Hi.
I'm back from my Hollidays and the cruel life.
I will try to install the plugin again and the atlasprint plugin, but it failed to.

I try to had those lines to the 000-default.conf but the qgis-server crashed ...

Did you make some progress?

I will try to install the plugin again and the atlasprint plugin, but it failed to.

Do you have any error message?

Check :

• Where QGIS is looking for plugins?
• If the folder is correct, wfsOutputExtension with the metadata.txt inside. Better to take the zip from release
• Check the rights on the file. root might not be good when unzipping

[aeduard]

I've also tried to enable wfsOutputExtension qgis-server plug-in. At first I had difficulties, because it was not clear to me where should I put the QGIS_PLUGINPATH line (having Apache2 with FastCGI). I've checked qgis-server documentation here. I've modified my configuration at sites-available, than conf-available (serve-cgi-bin.conf). Nothing happened, GET CAPABILITIES not worked. It was not clear for me which file should I modify.

Than I started to check each qgis-server plug-in documentation I could find, and at Atlasprint plug-in I've found clearly specified /etc/apache2/mods-available/fcgid.conf
There I've pasted the following lines, reload and restart apache2 service and GET CAPABILITIES and lizmap export started to work.

FcgidInitialEnv LC_ALL "en_US.UTF-8"
FcgidInitialEnv PYTHONIOENCODING UTF-8
FcgidInitialEnv LANG "en_US.UTF-8"
FcgidInitialEnv QGIS_SERVER_LOG_FILE /tmp/qgis-000.log
FcgidInitialEnv QGIS_SERVER_LOG_LEVEL 0
FcgidInitialEnv QGIS_PLUGINPATH "/opt/qgis-server/plugins"

I've extracted as root user, seems it's not an issue.
Still having problems with accented/special characters, as it doesn't get recognized at export. I've thought the first 3 lines in the above config would help, but it didn't. But generally the plug-in is working, and I'm happy with it.

[Gustry]

I have reviewed the readme quickly and added a link to the AtlasPrint just in case.
