OAuth 1.0 Client in simple words

oauth

    Authorization in simple words:
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    1. Construct a client with its client credentials.

    2. Send an HTTP request for temporary credentials with a callback URL
       which the server will call with an OAuth verification code.

    3. Parse out temporary credentials from a successful server response.

    4. Using the temporary credentials build an authorization URL and
       redirect the resource owner (end-user) to the generated URL.

    5. If a callback is not provided when requesting temporary credentials,
       the server displays the OAuth verification code to the resource owner
       (end-user), which she then types into your application.

       OR

       If a callback URL is provided, the server redirects the resource owner
       (end-user) after authorization to your callback URL attaching the
       OAuth verification code as a query parameter.

    6. Using the obtained OAuth verification code from step 5 and the
       temporary credentials obtained in step 3, send an HTTP request for
       token credentials.

    7. Parse out the token credentials from a successful server response.

    8. Save the token credentials for future use (say in a database).

    Accessing a resource:
    ~~~~~~~~~~~~~~~~~~~~~
    1. Construct a client with its client credentials.

    2. Using the token credentials that you have saved (say, in a database),
       send an HTTP request to a resource URL.

    3. Obtain the response and deal with it.
