C#實現(xiàn)的微信網(wǎng)頁授權(quán)操作邏輯封裝示例
本文實例講述了C#實現(xiàn)的微信網(wǎng)頁授權(quán)操作邏輯封裝。分享給大家供大家參考,具體如下:
一、微信網(wǎng)頁授權(quán)登錄
前提:
1.已經(jīng)獲取的接口權(quán)限,如果是測試賬號就已經(jīng)有權(quán)限了
2.配置接口的授權(quán)域名
更多說明可以參考方倍工作室:http://www.cnblogs.com/txw1958/p/weixin71-oauth20.html
或者官網(wǎng)API:http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html
步驟:
1.用戶同意授權(quán),獲取code
2.根據(jù)code 獲取access_token及當(dāng)前操作用戶的openid、unionid
3.根據(jù)openid獲取用戶基本信息(如果需要的話)
注:如果想在網(wǎng)站使用掃一掃,授權(quán)登錄,可以講 _oauth.GetCodeUrl() 授權(quán)地址生成二維碼來使用
C#封裝微信網(wǎng)頁授權(quán)登錄使用實例:
string appid = "wx145b4a8fd07b24e8"; string appsecrect = "fe6951dcb99772411c42f724b1336065"; string redirect_url = "配置域名下的回調(diào)地址"; OAuthManage _oauth = null; /// <summary> ///控制器構(gòu)造函數(shù) /// </summary> public UserController() { _oauth = new OAuthManage(appid, appsecrect, redirect_url); } /// <summary> /// 授權(quán)登錄 /// </summary> /// <returns></returns> public ActionResult AuthLogin() { ViewBag.url = _oauth.GetCodeUrl(); return View(); } /// <summary> /// 回調(diào)處理 /// </summary> /// <returns></returns> public ActionResult OAuthHandle() { string result = ""; //注冊事件處理 _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(); //顯示結(jié)果 ViewBag.msg = result; return View(); }
