Hi.
I’m using geoserver 2.8.1, builded from sources, and on runtime format.

I’m trying to run python code to do customs, in geoserver.

I did install the wps extension, create the data_dir/scripts/wps directory, and put my sample.py on it.
I’m not getting type py:sample on the demo/wps request builder.
I did detect (in the builded from sources version), a message “2016-06-01 18:14:22,784 DEBUG [script.wps] - Skipping sample.py, no hook found”

I did try, too, to install the python extension (documented on http://docs.geoserver.org/2.6.x/en/user/community/python/installation.html).
This method is no longer available in versions 2.8.x or higher? It was replaced by something else?

Surely I’m wrong in the process. someone can give me a hint?

TIA

Hi Jorge,

The docs you are looking at are for the old “python” extension that pre-dates the “script” extension. You should follow the documentation located here:

http://docs.geoserver.org/stable/en/user/community/scripting/index.html

In particular if you are looking to hook into wps you can find some details and samples here:

http://docs.geoserver.org/stable/en/user/community/scripting/hooks.html#web-processing-service

Hope that helps.

Ok, Justin.
I’m trying to use wps to implement my service.
I did try a basic “hello world” sample. My sample try to return a string with “hello world”:

#more scripts/wps/sample.py

from geoserver.wps import process
from StringIO import StringIO

@process(
title=‘Sample’,
description=‘Sample’,
inputs={},
outputs={‘result’: (StringIO, ‘The constant hello world’)}
)
def run():
buff = StringIO(“hello world”)
return buff;

When I try to execute the process with:
wget “http://localhost:8080/geoserver/wps?service=WPS&version=1.0.0&request=Execute&identifier=py:sample” -O -

I don’t have errors, but, I can’t to see the “hello world” text.
I’m thinking the problem is the output definition. What is the list of datatypes on this?

Ok. I did resolve it:

#from geoscript.geom import Geometry
from StringIO import StringIO

@process(
title=‘Sample’,
description=‘Sample’,
inputs={‘arg1’: (int, ‘first argument’),
‘arg2’: (int, ‘second argument’)},
outputs={‘result’: (str, ‘The buffered geometry’)}

def run(arg1, arg2):
#return “hello world”;
return str(arg1+arg2);

I’ll continue working on it. Thanks for the help.

Hi!
I’m trying to execute my wps script, using wget (to test), but, I need “login to geoserver” (like “Authenticate (will run the request as anonymous otherwise” checkbox on “WPS request builder”).
What is the method to do it?

I’m using the sentence:
wget “http://localhost:8080/geoserver/wps?service=WPS&version=1.0.0&request=Execute&identifier=py:sample1&datainputs=param1=xx;param2=yy” -O -

You need to provide the --user & --password options to WGET or if you use curl the option is -u username:passwd

Hi Jorge,

The docs you are looking at are for the old “python” extension that pre-dates the “script” extension. You should follow the documentation located here:

http://docs.geoserver.org/stable/en/user/community/scripting/index.html

In particular if you are looking to hook into wps you can find some details and samples here:

http://docs.geoserver.org/stable/en/user/community/scripting/hooks.html#web-processing-service

Hope that helps.

I’m seeing my problem is:

  • The caller is putting user and password.
  • The wps python script is running in anonymous mode.
  • What is the method to init the session on geoserver (from wps python script) with the user and password received?

You need to provide the --user & --password options to WGET or if you use curl the option is -u username:passwd

Hi!
I’m trying to execute my wps script, using wget (to test), but, I need “login to geoserver” (like “Authenticate (will run the request as anonymous otherwise” checkbox on “WPS request builder”).
What is the method to do it?

I’m using the sentence:
wget “http://localhost:8080/geoserver/wps?service=WPS&version=1.0.0&request=Execute&identifier=py:sample1&datainputs=param1=xx;param2=yy” -O -

Thanks

Ok. I did resolve it:

from geoserver.wps import process
#from geoscript.geom import Geometry
from StringIO import StringIO

@process(
title=‘Sample’,
description=‘Sample’,
inputs={‘arg1’: (int, ‘first argument’),
‘arg2’: (int, ‘second argument’)},
outputs={‘result’: (str, ‘The buffered geometry’)}
)
def run(arg1, arg2):
#return “hello world”;
return str(arg1+arg2);

I’ll continue working on it. Thanks for the help.

Ok, Justin.
I’m trying to use wps to implement my service.
I did try a basic “hello world” sample. My sample try to return a string with “hello world”:

#more scripts/wps/sample.py

from geoserver.wps import process
from StringIO import StringIO

@process(
title=‘Sample’,
description=‘Sample’,
inputs={},
outputs={‘result’: (StringIO, ‘The constant hello world’)}
)
def run():
buff = StringIO(“hello world”)
return buff;

When I try to execute the process with:
wget “http://localhost:8080/geoserver/wps?service=WPS&version=1.0.0&request=Execute&identifier=py:sample” -O -

I don’t have errors, but, I can’t to see the “hello world” text.
I’m thinking the problem is the output definition. What is the list of datatypes on this?

Hi Jorge,

The docs you are looking at are for the old “python” extension that pre-dates the “script” extension. You should follow the documentation located here:

http://docs.geoserver.org/stable/en/user/community/scripting/index.html

In particular if you are looking to hook into wps you can find some details and samples here:

http://docs.geoserver.org/stable/en/user/community/scripting/hooks.html#web-processing-service

Hope that helps.

Hi.
I’m using geoserver 2.8.1, builded from sources, and on runtime format.

I’m trying to run python code to do customs, in geoserver.

I did install the wps extension, create the data_dir/scripts/wps directory, and put my sample.py on it.
I’m not getting type py:sample on the demo/wps request builder.
I did detect (in the builded from sources version), a message “2016-06-01 18:14:22,784 DEBUG [script.wps] - Skipping sample.py, no hook found”

I did try, too, to install the python extension (documented on http://docs.geoserver.org/2.6.x/en/user/community/python/installation.html).
This method is no longer available in versions 2.8.x or higher? It was replaced by something else?

Surely I’m wrong in the process. someone can give me a hint?

TIA
