asp.net website to achieve access to QQ Login Sample Code _ Practical Skills

Say not much, directly on the code bar:

  String client_id = "assigned app ID";
  string AppID = "Assigned APP KEY";
  String Return_url = "return processed URL";
  public string Authorize ()
  {
   string state = new Random (100000). Next (99, 99999). ToString ();//random number
   Httphelper http = new Httphelper ();
   String url = string. Format ("https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id={0}&redirect_uri={1}& State={2} ", client_id, Return_url, state);
   String str= "<script> location.href= '" + URL + "' </script>";
   return str;
  
  }

Click the event to call directly Authorize() on it, I was directly with the Jump link processing.

 protected void Page_Load (object sender, EventArgs e)
  { 
   Qq_login q = new Qq_login ();
   String url = q.authorize ();//Here Call
   Response.Write (URL);
  }

Effect:

Click on the image, then call the following method in the URL of the callback, and then look a little further down;

  Public User_info Back_user (string code) {String state = new Random (100000). Next (99, 99999).
   ToString ();//random number User_info UI = new User_info (); String url = string. Format ("https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&client_id={0}&client_secret=
   {1}&code={2}&redirect_uri={3}&state={4} ", client_id, AppID, code, Return_url, state); String uu = Httphelper.htmlfromurlget (URL);//processing HTTP request Help class String code1 = Uu. Split (' & ') [0]. Split (' = ') [1]. ToString ();//Get Access_token//root Access_token Get user unique OpenID string url_me = string. 
   Format ("https://graph.qq.com/oauth2.0/me?access_token={0}", Code1); String callback = Httphelper.htmlfromurlget (Url_me);//The callback obtained here = callback. Substring (callback. IndexOf (' (') + 1, callback. IndexOf (') ')-callback. IndexOf (' (')-1)).
   Trim (); Dynamic JsonP = Jvalue.fromobject (callback); Here I am using a serialized class Library Newtonsoft.Json.dll 6.0.4 version of the helpless company version is only 4.0 version of the proposed use of 6.0.4 version a JsonP = Jsonconvert.deserializeoBject<a> (callback);//newtonsoft.json.dll 4.0 or 4.5 version of the string OpenID = jsonp.openid;//Get user only OpenID//under OpenID The user information can be displayed more with just a few needed to be able to add string GetInfo = string below. Format ("Https://graph.qq.com/user/get_user_info?access_token={0}&oauth_consumer_key={1}&openid={2}",
   Code1, client_id, OpenID);
   String user = Httphelper.htmlfromurlget (getinfo);
   b info = jsonconvert.deserializeobject<b> (user); Ui.
   Name = Info.nickname; Ui.
   OpenID = OpenID;
   ui.img_qq100 = info.figureurl_qq_1;
   Ui.img_qq50 = info.figureurl_qq_2;
   ui.city = info.city;
   Ui.year = Info.year; Ui.
   Type = 1; 
 
  return UI; }

Click on the image to jump to the specified callback address, and redirect_uri after the address with Authorization Code ;

User_info UI = new User_info ();
     var verifier = request.params["code"]; Get authorization Code
     UI = Q.back_user (verifier); Drop method and return data

Then post the returned class.

  public class User_info
  {public
   string OpenID {get; set;} User unique AppID public
 
   string Name {get; set;} 
 
   public string Img_qq50 {get; set;}//qq image 40*40 public
 
   string img_qq100 {get; set;}
 
   public string City {get; set;}

   public int year {get; set;} 
  }

 public Class A {public
 
  string client_id {get; set;}
 
  public string OpenID {get; set;}
 }

Summarize

Basically finished, code on so much, interested students hands-on operation can be more familiar with the hope that this article can help.
