Application Address: Https://open.weixin.qq.com/cgi-bin/index?t=home/index&lang=zh_CN

2 View the interface provided by the micro-letter, write Java code

 public void wx () {try {response.sendredirect ("https://open.weixin.qq.com/connect/qrconnect?appid=" + sharelogind Ict. Weixinkey.getstate () + "&redirect_uri=" + Urlencoder.encode (ShareLoginDict.WEIXINURL.getState ()) + "&res
 Ponse_type=code&scope=snsapi_login&state=66666#wechat_redirect ");
 catch (IOException e) {//TODO auto-generated catch block E.printstacktrace ();
 @Override public result userwx (String return_code) {result result = new result ();
 Map<string, object> token = (map<string, object>) weixinapi. GetToken (Return_code); if (token!= null && token.get ("Access_token")!= null) {map<string, object> user = (map<string, objec
  t>) Weixinapi. Getwxuser (Token.get ("Access_token"). ToString (), Token.get ("OpenID"). ToString ());
  if (user!= null) {Result.addmodel ("OpenID", User.get ("OpenID"));
  Result.addmodel ("nickname", User.get ("nickname")); Result.addmodel ("Headimgurl", User.get ("HeadiMgurl "));
  Result.addmodel ("Data", "data_success");
  }else{Result.addmodel ("Data", "Data_null");
 }}else{Result.addmodel ("Data", "Data_null");
 return result;

 }

When the user is logged in by a micro-letter, call the micro-interface to obtain the user interface to return the micro-client OpenID, nickname, Avatar; then deposit this information in the browser's cookie, and when the user browses other information, identify if the user is logged in with a micro-letter, The interceptor directly retrieves the user's information from the cookie to display the nickname and Avatar, and at the same time determines whether the OpenID is bound to the user in the database, if no binding prompts the user to register.

2, QQ Login

1) QQ Interconnection creation Application

Access QQ before login, the site needs to apply first, to obtain the corresponding AppID and Appkey, to ensure that the following process can be correct for the site and users to authenticate and authorize.

Applications for AppID and Appkey

AppID: Unique identification of the application. During the OAuth2.0 authentication process, the AppID value is the Oauth_consumer_key value.

Appkey:appid the corresponding key to verify the legality of the application when accessing user resources. During the OAuth2.0 authentication process, the Appkey value is the Oauth_consumer_secret value.

Application Address: http://connect.qq.com/intro/login/

2 to see the interface provided by QQ, write Java code

public void QQ () {try {response.sendredirect ("https://graph.qq.com/oauth2.0/authorize?response_type=code& Client_id= "+ ShareLoginDict.QQKEY.getState () +" &redirect_uri= "+ ShareLoginDict.QQURL.getState () +" &SC
 Ope=get_user_info ");
 catch (IOException e) {//TODO auto-generated catch block E.printstacktrace ();
 @Override public result Userqq (String return_code) {result result = new result ();
 Map<string, object> token = (map<string, object>) qqapi. GetToken (Return_code); if (token!= null && token.get ("Access_token")!= null) {map<string, object> Tokenme = (map<string, Ob
  ject>) Qqapi. Gettokenmeopenid (Token.get ("Access_token"). toString ()); if (Tokenme!= null && tokenme.get ("OpenID")!= null) {map<string, object> user = (map<string, object& gt;)
  Qqapi. Getqquser (Token.get ("Access_token"). ToString (), Tokenme.get ("OpenID"). ToString ()); if (user!= null) {Result.addmodel ("OPenid ", Tokenme.get (" OpenID "));
   Result.addmodel ("nickname", User.get ("nickname"));
   Result.addmodel ("Figureurl", User.get ("Figureurl"));
  Result.addmodel ("Data", "data_success");
  }else{Result.addmodel ("Data", "Data_null");
  }}else{Result.addmodel ("Data", "Data_null");
 }}else{Result.addmodel ("Data", "Data_null");
 return result; 

 }

 Weibokey.getstate () + "&redirect_uri=" + ShareLoginDict.WEIBOURL.getState () + "&response_type=code");
 catch (IOException e) {//TODO auto-generated catch block E.printstacktrace ();
 @Override Public result USERWB (string return_url, string return_code) {result result = new result ();
 Map<string, object> token = (map<string, object>) Weiboapi.gettoken (Return_url, Return_code); if (token!= null && token.get ("Access_token")!= null) {map<string, object> user = (map<string, objec
  t>) Weiboapi. Getwbuser (Token.get ("Access_token"). ToString (), Token.get ("UID"). ToString ());
  if (user!= null) {Result.addmodel ("name", User.get ("Screen_name"));
  Result.addmodel ("Pic", User.get ("Avatar_large"));
  Result.addmodel ("Idstr", User.get ("Idstr"));
  Result.addmodel ("Data", "data_success");
}else{  Result.addmodel ("Data", "Data_null");
 }}else{Result.addmodel ("Data", "Data_null");
 return result;

 }
