Example service

Clone the example service after having installed PyWPS:

git clone git://github.com/geopython/pywps-flask.git pywps-flask
cd pywps-flask
python demo.py

Apache configuration

1. Enable WSGI extension

2. Add configuration:

   WSGIDaemonProcess pywps user=user group=group processes=2 threads=5
   WSGIScriptAlias /pywps /path/to/www/htdocs/wps/pywps.wsgi
   
   <Directory /path/to/www/htdocs/wps/>
       WSGIProcessGroup group
       WSGIApplicationGroup %{GLOBAL}
       Order deny,allow
       Allow from all
   </Directory>

3. Create wsgi file:

   #!/usr/bin/env python3
   import sys
   sys.path.append('/path/to/src/pywps/')
   
   import pywps
   from pywps.app import Service, WPS, Process
   
   def pr1():
       """This is the execute method of the process
       """
       pass
   
   application = Service(processes=[Process(pr1)])

4. Run via web browser

   http://localhost/pywps/?service=WPS&request=GetCapabilities&version=1.0.0

5. Run in command line:

   curl 'http://localhost/pywps/?service=WPS&request=GetCapabilities&version=1.0.0'

Issues

On Windows PyWPS does not support multiprocessing which is used when making requests storing the response document and updating the status to displaying to the user the progression of a process.
