The document discusses the steps for implementing OAuth authentication with Facebook. It involves: 1. Sending an OAuth request to Facebook with the application ID. 2. Requesting required permissions/scopes to access the user's account. 3. Receiving an access token and access verifier from Facebook. 4. Storing the token in a database to reuse it for making API calls to get/post user status updates or other information.
OAuth Linking-Social Networks
- 2. Steps: 1. Sending the request using Oauth_id of the application to facebook 2. Sending the permission(parameter,scope) required to access and account 3. Getting the access_token,access_verfier from the server(facebook) 4. Storing it in out database to reuse the token 5. Using the token we “Get” /”Post” the status or any information of the user 6. We store the fbuserid(pageId) of the particular user/page so as to identify the user/page 7. In return if we “POST” of any status or message we get an id which is the id of the POST or message we store that in the database so as to reuse the information of the post
- 3. It was introduced in 2006 Make User grant access to the private resources of the one website(service provider) to another website (the consumer) OAuth attempts to provide a standard way for developers to offer their services via an API without forcing their users to expose their passwords
- 4. 1. Token: Unique Identifier issued by server 2. CallBack Uri: Url to which the page is redirected after authentication or Authorization 3. Oauth_token : Temporary credentials identifier 4. Oauth_token_secret : Temporary Credentials shared secret 5. Oauth_verifier: The verification code received from the server in the previous step. 6. Oauth_callback_confirmed: It must be present and set value true. This parameter is used to differentiate from previous versions of protocol 7. http/1.1 XXX: STATUS 1. 200 : Status Ok – Success 2. 403 : Status Not Ok – Un Authorized 3. 400: Status Not Ok – Bad Request
