Android Sina Weibo Certification

Sina Weibo has been very tangled, and Auth authentication is a sign of blood. Previously, the project was used by others. Recently I want to know more about it, so that I can use it better in the future.

Be sure to keep the following Constants

Public String consumerkey = "2803926882"; // key
Public String consumersecret = "d41e6f2d605bd16c785879032ec431f5"; // secret
// Customize the callback URL (this URL must be configured in the configuration file ,)
Public static final string callback_url = "jjhappyforever: // weibolistactivity ";

// Requesttokenurl
Private final string requesttokenendpointurl = "http://api.t.sina.com.cn/oauth/request_token ";
// Accesstokenurl
Private final string accesstokenendpointurl = "http://api.t.sina.com.cn/oauth/access_token ";
// Authorization
Private final string authorizationwebsiteurl = "http://api.t.sina.com.cn/oauth/authorize ";

The following two methods are used in oauth. java.

// Obtain the auth address
Public String retrieveauthurl () throws oauthmessagesignerexception,
Oauthnotauthorizedexception, oauthexpectationfailedexception,
Oauthcommunicationexception {
Authconsumer = new commonshttpoauthconsumer (consumerkey, consumersecret );
Authprovider = new commonshttpoauthprovider (requesttokenendpointurl,
Accesstokenendpointurl, authorizationwebsiteurl );
Return authprovider. retrieverequesttoken (authconsumer, callback_url );
}

// This method is used to obtain the user's userid, Token, tokensecret, and other information.

Public user getaccesstoken (string authurl)
Throws oauthmessagesignerexception, oauthnotauthorizedexception,
Oauthexpectationfailedexception, oauthcommunicationexception {

Log. I (TAG, authurl );

Authprovider. setoauth10a (true );
Authprovider. retrieveaccesstoken (authconsumer, authurl );
User user = new user ();
User. userid = authprovider. getresponseparameters (). getfirst ("user_id ");
User. Token = authconsumer. gettoken ();
User. tokensecret = authconsumer. gettokensecret ();
Return user;
}

Called in activity.

// Obtain the authurl address
String authurl = oauth. retrieveauthurl ();
// Start accessing the Sina Certification Page
Startactivity (new intent (intent. action_view, Uri. parse (authurl )));

In this way, Web authentication is performed.

The onnewintent method is implemented in this activity to execute the action after the authentication callback,

Protected void onnewintent (intent ){
Super. onnewintent (intent );
Uri uri = intent. getdata ();
String verifier = URI. getqueryparameter (oauth. oauth_verifier );
Try {
User user = NULL;
User = oauth. getaccesstoken (verifier );
Log. I (oauth. Tag, user. tostring ());
} Catch (oauthmessagesignerexception ex ){
Ex. printstacktrace ();
} Catch (oauthnotauthorizedexception ex ){
Ex. printstacktrace ();
} Catch (oauthexpectationfailedexception ex ){
Ex. printstacktrace ();
} Catch (oauthcommunicationexception ex ){
Ex. printstacktrace ();
}
}

 

Here we will talk about the configuration in the configuration file:

<Activity
Android: Name = ". testactivity"
Android: launchmode = "singleinstance"> <! --- This lanchmode mode must be set. If this mode is not set, oncreate will be executed all the time. onnewintent will not be executed. I am stuck here for a long time. -->
<Intent-filter>
<Action Android: Name = "android. Intent. Action. View"/>

<Category Android: Name = "android. Intent. Category. Default"/>
<Category Android: Name = "android. Intent. Category. browsable"/>

<Data
Android: host = "oauth"
Android: Scheme = "jjhappyforevert"/>
</Intent-filter>
</Activity>

 

The oauth authentication process is implemented here. Next, we will briefly introduce the Weibo information that can be called by users based on open platform APIs.
