papyrus_ogcproxy
Project description
papyrus_ogcproxy provides an easy and convenient method for embeding an OGC proxy in Pyramid applications.
The source code of papyrus_ogcproxy is straightforward, so if papyrus_ogcproxy doesn’t do what you want, open its source code, get inspiration, and write your own code.
Install
papyrus_ogcproxy can be installed with easy_install:
$ easy_install papyrus_ogcproxy
Often you’ll want to make papyrus_ogcproxy a dependency of your Pyramid application, which is done by adding papyrus_ogcproxy to the install_requires list defined in the Pyramid application’s setup.py file.
Set up
Using papyrus_ogcproxy to set up an OGC proxy in a Pyramid application is easy.
Edit the application’s main file, __init__.py, and register papyrus_ogcproxy using the Configurator.include method:
def main(global_config, **settings): config = Configurator(settings=settings) import papyrus_ogcproxy config.include(papyrus_ogcproxy)
That’s it! The OGC proxy is available at /ogcproxy.
Here is a test URL: http://localhost:6543/ogcproxy?url=http%3A%2F%2Fmap1.vis.earthdata.nasa.gov/wmts-geo/wmts.cgi%3FSERVICE%3DWMTS%26REQUEST%3DGetCapabilities
Using a proxy for the proxy
If the requests made by the OGC proxy should be made through a proxy, the additional package pysocks is required. After the installation of this package, configure the proxy:
from papyrus_ogcproxy import views as ogcproxy_views from httplib2 import ProxyInfo import socks ogcproxy_views.proxy_info = ProxyInfo(socks.SOCKS5, 'localhost', 1080)
With this configuration the OGC proxy will make requests through the proxy localhost:1080. For information please refer to the documentation of PySocks and httplib2.
Set up a development environment
To set up a development environment with virtualenv, run the following commands:
$ virtualenv venv $ venv/bin/python setup.py develop $ venv/bin/pip install -r requirements-dev.txt
Run the tests
To run the tests:
$ venv/bin/nosetests --with-coverage
One test assumes that a proxy server is running at localhost:1080. To start a proxy run:
$ ssh -N -D 0.0.0.0:1080 localhost

Do not verify certificate from the remote server. https://github.com/elemoine/papyrus_ogcproxy/pull/4 from @sbrunner. (We may want to revisit this later.)
