Learning Registry OAuth Sample

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
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"
}
# Just a dummy resource data document
resource_doc = {
"doc_type": "resource_data",
"doc_version": "0.23.0",
"active": True,
"resource_data_type": "metadata",
"resource_locator": "http://example.com/oauth-sample/resource",
"keys": [],
"payload_placement": "inline",
"payload_schema": ["sample"],
"resource_data": "This is sample data",
"TOS": {
"submission_TOS": "http://www.learningregistry.org/information-assurances/open-information-assurances-1-0"
}
}
def Oauth2Lib():
# Create your consumer with the proper key/secret.
consumer = oauth.Consumer(key=_consumer["key"],
secret=_consumer["secret"])
token = oauth.Token(key=_token["key"],
secret=_token["secret"])
# Create our client.
client = oauth.Client(consumer, token=token)
# we only need to do this because Sandbox uses a self-signed SSL cert that is untrusted. This should not be needed on production.
client.disable_ssl_certificate_validation=True
# This request just allows you to Test your OAuth Credentials, if it succeeds it will return the contents of your user profile
resp, content = client.request(_testing_url, "POST", body=json.dumps({"documents": [resource_doc]}), headers={"Content-Type": "application/json"})
print resp

print resp.read()
