This paper illustrates the logic encapsulation of the authorization operation of the micro-letter Web page implemented by C #. Share to everyone for your reference, specific as follows:

First, the micro-letter Web page Authorized Login

Premise:

1. The interface permission has been acquired, if the test account has already been authorized

2. Configure the interface's authorized domain name

More instructions can refer to the Square Times studio: http://www.cnblogs.com/txw1958/p/weixin71-oauth20.html

or the official website api:http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html

Steps:

1. Users agree to authorize, get code

2. According to code to obtain Access_token and current operating user's OpenID, Unionid

3. Obtain basic user information based on OpenID (if required)

Note: If you want to use a sweep on the website, authorize login, you can speak _oauth. Getcodeurl () authorization address to generate a two-dimensional code to use

C # encapsulated micro-letter Web page Authorization login usages:

string AppID = "Wx145b4a8fd07b24e8";
String appsecrect = "fe6951dcb99772411c42f724b1336065";
String Redirect_url = "The callback address under the configuration domain name";
Oauthmanage _oauth = null; <summary>///Controller Constructor///</summary> public Usercontroller () {_oauth = new Oauthmanage (AppID, Appsecrect
, Redirect_url);
  ///<summary>///Authorized login///</summary>///<returns></returns> public ActionResult Authlogin () { Viewbag.url = _oauth.
  Getcodeurl ();
return View (); 
///<summary>///callback processing///</summary>///<returns></returns> public actionresult oauthhandle ()
  {String result = ' "; Registers event handling _oauth.
    OnError = (e) => {string msg = "";
    Exception inner = e; while (inner!= null) {msg = inner.
      message; Inner = inner.
    innerexception;
    result = msg;
  Logoperate.write (msg);
  }; _oauth.
    Ongettokensuccess = (token) => {result = = "<br/>"; result = token.
  toJSONString ();
  }; _oauth. Ongetuserinfosuccess = (user) => {result = "<br/>"; result = user.
  toJSONString ();
  }; The second step is _oauth.
  Getaccess_token (); The third step is _oauth.
  GetUserInfo ();
  Display results viewbag.msg = result;
return View ();

 }
