Hi Tom,
When I run your script, I get the following response:
This script can only be used to decode form results and
should be initiated as a CGI process via a httpd server.
This answer does not contain any content-type that can be stripped with
msIO_getStdoutBufferBytes(). That's why it returns None.
Before your OWSRequest call, you need to set the Environment variable
that MapServer needs. Otherwise they are passed in the env variable and
not to MapServer. Code to add:
# List of all environment variable used by MapServer
mapserv_env = [
'CONTENT_LENGTH', 'CONTENT_TYPE', 'CURL_CA_BUNDLE', 'HTTP_COOKIE',
'HTTP_HOST', 'HTTPS', 'HTTP_X_FORWARDED_HOST', 'HTTP_X_FORWARDED_PORT',
'HTTP_X_FORWARDED_PROTO', 'MS_DEBUGLEVEL', 'MS_ENCRYPTION_KEY',
'MS_ERRORFILE', 'MS_MAPFILE', 'MS_MAPFILE_PATTERN', 'MS_MAP_NO_PATH',
'MS_MAP_PATTERN', 'MS_MODE', 'MS_OPENLAYERS_JS_URL', 'MS_TEMPPATH',
'MS_XMLMAPFILE_XSLT', 'PROJ_LIB', 'QUERY_STRING', 'REMOTE_ADDR',
'REQUEST_METHOD', 'SCRIPT_NAME', 'SERVER_NAME', 'SERVER_PORT'
]
for key in mapserv_env:
if key in env:
os.environ[key] = env[key]
else:
os.unsetenv(key)
request = mapscript.OWSRequest()
Best regards,
Julien

Hi all: we are looking into updating our Python MapScript (CGI-based) wrappers
to leverage WSGI, and are having integration issues as part of testing.
We are using 6.4.2 on Ubuntu 14.04. See example in [1] (against
any mapfile is fine). Simple run with python ./mapscript-wsgi.py which makes
the server available on localhost:8000 by default.
Issues:
- the value in
https://gist.github.com/tomkralidis/9adbd4864c03647aa7eb4f96a3c33297#file-mapscript-wsgi-py-L18
ends up being a Python None type for some reason when it should be a string of
the content-type
- issuing a, say, WMS 1.3.0 GetCapabilities request yields the venerable MapServer
"This script can ...." default message, when I am expecting Capabilities XML
Any ideas what I'm doing wrong here?
