Field Detail

O_AUTH_1_NO_CALLBACK

public static final OAuth1NoCallback O_AUTH_1_NO_CALLBACK

Construct the OAuth1NoCallback instance. Usually, this would be done via injection, or a configuration bean in Spring. Note: we use the preset HashMapTokenMapStrategy as the temporary token to token secret mapping strategy. It's recommended to use a custom implementation using a database.

Method Detail

main

public static void main(String[] args)
                 throws IOException,
                        OAuthBackedRequestException,
                        GetAccessTokenException,
                        GetTemporaryTokenException,
                        TokenMapException

This application: 1. Obtains and displays a temporary token and redirect URL from the service provider. 2. Waits for the user to verify the temporary token by polling until a key-press occurs. 3. After a key-press occurs, obtains and displays an access token from the service provider using their temporary token. 4. Makes a request on the behalf of the user to the resource server using their access token, and displays the result. The application assumes the entire process went smoothly, by throwing all checked exceptions. In practise, the checked exceptions would be caught and handled appropriately.

Throws:

IOException

OAuthBackedRequestException

GetAccessTokenException

GetTemporaryTokenException

TokenMapException

begin

public static BeginResult begin()
                         throws GetTemporaryTokenException,
                                TokenMapException

The begin endpoint, i.e. requesting a temporary token to obtain a redirect URL where the user shall go to verify the token. This endpoint assumes the entire process went smoothly, by throwing all checked exceptions. In practise, the checked exceptions would be caught and handled appropriately. If either a GetTemporaryTokenException or TokenMapException occurred, it can be assumed that a temporary token was unsuccessfully obtained.

Throws:

GetTemporaryTokenException

TokenMapException

authorised

public static AuthorisedResult authorised(String temporaryToken)
                                   throws GetAccessTokenException,
                                          TokenMapException

The authorised endpoint, i.e. requesting an access token corresponding to a temporary token which was verified by the user. This endpoint assumes the entire process went smoothly, by throwing all checked exceptions. In practise, the checked exceptions would be caught and handled appropriately. If either a GetAccessTokenException or TokenMapException occurred, it can be assumed that an access token was unsuccessfully obtained.

Throws:

GetAccessTokenException

TokenMapException
