NOTE: If you're having trouble installing this, there's an equivalent JavaScript version (mojodna/node-oauth-proxy) that's installed via npm install -g oauth-proxy (once you've installed Node.js). It's intended to be drop-in compatible.

I am an OAuth proxy server. You can pass unsigned requests to me and I will sign them using OAuth before sending them to their eventual destination.

At the moment, tokens and consumer keys are configurable only at start-time, so individual proxies are limited to a single pair at a time. 2-legged OAuth (often used in lieu of API keys) is supported by omitting --token and --token-secret options.

Install via easy_install:

$ easy_install oauth-proxy

or pip:

$ pip install oauth-proxy

It will automatically download and install the Python OAuth lib (oauth) and Twisted (if necessary).

Run the proxy with the provided oauth-proxy command:

$ oauth-proxy \
    --consumer-key <consumer key> \
    --consumer-secret <consumer secret> \
    [--token <token>] \
    [--token-secret <token secret>] \
    [-p <proxy port>] \
    [--ssl]

If you'd like to run the proxy as a daemon, run it with twistd directly:

$ twistd oauth_proxy \
    --consumer-key <consumer key> \
    --consumer-secret <consumer secret> \
    [--token <token>] \
    [--token-secret <token secret>] \
    [-p <proxy port>] \
    [--ssl]

This proxy can be used with command-line tools and web browsers alike.

To use it with curl:

$ curl -x localhost:8001 https://host.name/path

To use it with ab (ApacheBench):

$ ab -X localhost:8001 https://host.name/path

To use it with Firefox, open the Network settings panel, under Advanced, and set a "Manual Proxy Configuration" after clicking the "Settings..." button. Ensure that "No Proxy for" does not include the host that you are attempting to explore.

More information on using this proxy, including instructions for obtaining access tokens, is available in Exploring OAuth-Protected APIs.
