OAuth Sample

This is a trivial example of publishing to Learning Registry using OAuth 1.0 authored in python 2.7.

To use, you will need to install the oauth2 library:

    pip install oauth2

Once installed execute using:

    python oauth-sample.py

oauth-sample.py

import json, urllib, oauth2 as oauth


# Sample publish to LR Sandbox using OAuth

_netloc = "sandbox.learningregistry.org"
_testing_url = "https://%s/auth/oauth_verify" % _netloc
_publish_url = "https://%s/publish" % _netloc
_obtain_url = "https://%s/obtain?by_doc_ID=true&request_ID=%s"

# Go to https://sandbox.learningregistry.org/auth to create a publishing account, 
# Replace the Consumer and Token keys and secrets below with the ones generated there.

_consumer =  {
    "key": "jim.klo@sri.com",
    "secret": "eQMlCjUC88CjCOYgGgnHm1t48H48UF43"
}

_token = {
    "key": "node_sign_token",
    "secret": "lRMhkV6rIEl1xSvppkym7KSpwgHEYkCJ"
}
