本文實例講述了C#完成的微信網頁受權操作邏輯封裝。分享給年夜家供年夜家參考，詳細以下：

1、微信網頁受權登錄

條件：

1.曾經獲得的接口權限，假如是測試賬號就曾經有權限了

2.設置裝備擺設接口的受權域名

更多解釋可以參考方倍任務室：http://www.cnblogs.com/txw1958/p/weixin71-oauth20.html

或許官網API：http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html

步調：

1.用戶贊成受權，獲得code

2.依據code 獲得access_token及以後操感化戶的openid、unionid

3.依據openid獲得用戶根本信息(假如須要的話)

注：假如想在網站應用掃一掃，受權登錄，可以講 _oauth.GetCodeUrl() 受權地址生成二維碼來應用

C#封裝微信網頁受權登錄應用實例：

string appid = "wx145b4a8fd07b24e8";
string appsecrect = "fe6951dcb99772411c42f724b1336065";
string redirect_url = "設置裝備擺設域名下的回調地址";
OAuthManage _oauth = null;
/// <summary>
///掌握器結構函數
/// </summary>
public UserController()
{
  _oauth = new OAuthManage(appid, appsecrect, redirect_url);
}
/// <summary>
/// 受權登錄
/// </summary>
/// <returns></returns>
public ActionResult AuthLogin()
{
  ViewBag.url = _oauth.GetCodeUrl();
  return View();
}
/// <summary>
/// 回調解理
/// </summary>
/// <returns></returns>
public ActionResult OAuthHandle()
{
  string result = "";
  //注冊事宜處置
  _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();
  };
  //第二步
  _oauth.GetAccess_Token();
  //第三步
  _oauth.GetUserInfo();
  //顯示成果
  ViewBag.msg = result;
  return View();
}
