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>
  1. 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)])
  1. Run via web browser

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

  2. 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.
