Code

    "You are unauthenticated. (API protected by OAuth)." In browser:
    http://localhost:8000/api/posts.json

    Add/Auth new creds/token "by hand as admin":
    http://localhost:8000/admin/piston/token/ #IMPORTANT "token type"=access, "is approved":checked, User:correct one

    Authorizing Token (logged in as Admin):
    http://localhost:8000/api/oauth/authorize/?oauth_token=3Szw3AU5bkMV6QTVnR



File changed for Django Piston Oauth "blogserver" Example
---------------------------------------------------------
piston/templates/oauth/challenge.html
piston/templates/oauth/authorize_token.html
piston/templates/api/mails/consumer_accepted.txt

settings.py
oauth_client.py 
python-oauth2/oauth2/__init__.py


Running Client
--------------
    $ curl http://localhost:8000/api/posts.json -F "title=test" # No OAuth, returns "unauthorized"
    # make sure "oauth_client.py" has correct hostname
    $ python oauth_client.py #create new token/secret, put "oauth_token" link in browser, "what is PIN? aka 'oauth_verifier'"

    #using OAuth Twisted proxy as described in next section
    $ curl -x localhost:8001 http://localhost:8000/api/posts.json" -F "title=test" -F "content=blah"

OAuth Twisted Proxy (conveniently wrap each call with OAuth creds)
----------------------------------------------------------------
    pip -E piston_env/ install twisted
    cd piston_env/
    git clone git://github.com/mojodna/oauth-proxy.git
    source bin/activate
    cd oauth-proxy
    twistd -n oauth_proxy --consumer-key testkey --consumer-secret testsecret --token $TOKEN --token-secret $SECRET
