Constructor Detail

ConnectController

@Inject
public ConnectController(ConnectionFactoryLocator connectionFactoryLocator,
                                ConnectionRepository connectionRepository)

Constructs a ConnectController.

Parameters:

connectionFactoryLocator - the locator for ConnectionFactory instances needed to establish connections

connectionRepository - the current user's ConnectionRepository needed to persist connections; must be a proxy to a request-scoped bean

Method Detail

setInterceptors

public void setInterceptors(java.util.List<ConnectInterceptor<?>> interceptors)

Configure the list of interceptors that should receive callbacks during the connection process. Convenient when an instance of this class is configured using a tool that supports JavaBeans-based configuration.

Parameters:

interceptors - the connect interceptors to add

setApplicationUrl

public void setApplicationUrl(java.lang.String applicationUrl)

Configures the base secure URL for the application this controller is being used in e.g. https://myapp.com. Defaults to null. If specified, will be used to generate OAuth callback URLs. If not specified, OAuth callback URLs are generated from web request info. You may wish to set this property if requests into your application flow through a proxy to your application server. In this case, the request URI may contain a scheme, host, and/or port value that points to an internal server not appropriate for an external callback URL. If you have this problem, you can set this property to the base external URL for your application and it will be used to construct the callback URL instead.

Parameters:

applicationUrl - the application URL value

addInterceptor

public void addInterceptor(ConnectInterceptor<?> interceptor)

Adds a ConnectInterceptor to receive callbacks during the connection process. Useful for programmatic configuration.

Parameters:

interceptor - the connect interceptor to add

connectionStatus

@RequestMapping(method=GET)
public java.lang.String connectionStatus(org.springframework.web.context.request.NativeWebRequest request,
                                                        org.springframework.ui.Model model)

Render the status of connections across all providers to the user as HTML in their web browser.

connectionStatus

@RequestMapping(value="/{providerId}",
                method=GET)
public java.lang.String connectionStatus(@PathVariable
                                                        java.lang.String providerId,
                                                        org.springframework.web.context.request.NativeWebRequest request,
                                                        org.springframework.ui.Model model)

connect

@RequestMapping(value="/{providerId}",
                method=POST)
public org.springframework.web.servlet.view.RedirectView connect(@PathVariable
                                                                                java.lang.String providerId,

Process a connect form submission by commencing the process of establishing a connection to the provider on behalf of the member. For OAuth1, fetches a new request token from the provider, temporarily stores it in the session, then redirects the member to the provider's site for authorization. For OAuth2, redirects the user to the provider's site for authorization.

oauth1Callback

@RequestMapping(value="/{providerId}",
                method=GET,
                params="oauth_token")

                                                                                       java.lang.String providerId,

Process the authorization callback from an OAuth 1 service provider. Called after the user authorizes the connection, generally done by having he or she click "Allow" in their web browser at the provider's site. On authorization verification, connects the user's local account to the account they hold at the service provider Removes the request token from the session since it is no longer valid after the connection is established.

oauth2Callback

@RequestMapping(value="/{providerId}",
                method=GET,
                params="code")
public org.springframework.web.servlet.view.RedirectView oauth2Callback(@PathVariable
                                                                                       java.lang.String providerId,
                                                                                       org.springframework.web.context.request.NativeWebRequest request)

Process the authorization callback from an OAuth 2 service provider. Called after the user authorizes the connection, generally done by having he or she click "Allow" in their web browser at the provider's site. On authorization verification, connects the user's local account to the account they hold at the service provider.

removeConnections

@RequestMapping(value="/{providerId}",
                method=DELETE)
public org.springframework.web.servlet.view.RedirectView removeConnections(@PathVariable
                                                                                          java.lang.String providerId,
                                                                                          org.springframework.web.context.request.NativeWebRequest request)

Remove all provider connections for a user account. The user has decided they no longer wish to use the service provider from this application. Note: requires HiddenHttpMethodFilter to be registered with the '_method' request parameter set to 'DELETE' to convert web browser POSTs to DELETE requests.

removeConnection

@RequestMapping(value="/{providerId}/{providerUserId}",
                method=DELETE)
public org.springframework.web.servlet.view.RedirectView removeConnection(@PathVariable
                                                                                         java.lang.String providerId,
