网站接入qq登录

网站接入qq登录可以省去注册账号,增加网站的体验度。那么要实现我自己搭建的站点天天博客的qq单点登录需要以下几个步骤:
1,申请appid和appkey
 首先要去https://connect.qq.com/去申请一个网站的qq接入,申请成功时会给一个appid和appkey,前提是要有一个站点。
  
2,qq登录跳转
申请成功后,开始进行qq登录开发,根据官方文档,需要在放置一个qq登录的图标,然后点击这个图标跳转qq认证登录页。
如下图:

点击登录之后会跳转到相应的页面如下:要确保你的回调页面和申请里面写的一样并且要将url进行URLEncode

当qq登录成功后悔跳转到回调页面,并且会在url里面带上上Authorization Code的值。

3,获取AccessToken
通过Authorization Code获取Access Token,我选择通过后端代码调用,因为前段会出现跨域问题,以下是我的封装的方法

  /// <summary>         /// 获取AccessToken         /// </summary>         /// <param name="authorizationCode"></param>         /// <returns></returns>         public static async Task<string> GetAccessToken(string authorizationCode)         {             if (string.IsNullOrEmpty(authorizationCode))                 throw new AuthException("qq认证登录失败:authorizationCode为空");             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}&fmt=json", appId, appKey, authorizationCode, redirectUrl);             HttpClient httpClient = new HttpClient();             string response = await httpClient.GetStringAsync(url);             dynamic result = JsonHelper.DeserializeObject(response);             string error = result.error;             if (!string.IsNullOrEmpty(error))                 throw new AuthException("qq认证登录失败:" + result.error_description);             return result.access_token;          }

4,获取openid
通过token获取openid,其中openid就想当与一个qq号码,唯一的:

  /// <summary>         /// 获取OpenId         /// </summary>         /// <param name="authorizationCode"></param>         /// <returns></returns>         public static async Task<string> GetOpenId(string accessToken)         {             if (string.IsNullOrEmpty(accessToken))                 throw new AuthException("qq认证登录失败:accessToken无效");             string url = "https://graph.qq.com/oauth2.0/me?fmt=json&access_token=" + accessToken;             HttpClient httpClient = new HttpClient();             string response = await httpClient.GetStringAsync(url);             dynamic result = JsonHelper.DeserializeObject(response);             string error = result.error;             if (!string.IsNullOrEmpty(error))                 throw new AuthException("qq认证登录失败:"+result.error_description);             return result.openid;          }

5,通过token和openid获取qq信息:

  /// <summary>         /// 获取qq信息         /// </summary>         /// <param name="authorizationCode"></param>         /// <returns></returns>         public static async Task<UserModel> GetQQUser(string accessToken,string openId)         {             if (string.IsNullOrEmpty(accessToken))                 throw new AuthException("accessToken无效");             if (string.IsNullOrEmpty(openId))                 throw new AuthException("openId");             string url = string.Format("https://graph.qq.com/user/get_user_info" +                  "?access_token={0}&openid={1}&appid={2}&fmt=json", accessToken, openId, appId);             HttpClient httpClient = new HttpClient();             string response = await httpClient.GetStringAsync(url);             dynamic result = JsonHelper.DeserializeObject(response);             if (result.ret != 0)                 throw new AuthException("qq认证登录失败:" + result.msg);             UserModel userModel = new UserModel();             userModel.Account = openId;             userModel.Username = result.nickname;             userModel.LoginType = Blog.Domain.Core.LoginType.QQ;             userModel.Sex = result.gender;             userModel.HeadPhoto = result.figureurl_qq_2;             return userModel;          }

6,处理qq信息
到此,qq账号的信息以及获取完成了,接下来就是根据自己的业务来处理qq账号信息了,我选择将qq信息存入user表,后端将qq信息转为对应的user,放入jwt里面生成token:

  [Route("login/{code}")]         [HttpGet]         public async Task<ApiResult> Login(string code)         {             string accessToken =await QQClient.GetAccessToken(code);             string openId = await QQClient.GetOpenId(accessToken);             UserModel userModel = await QQClient.GetQQUser(accessToken, openId);             _userService.Insert(userModel);             IList<Claim> claims = new List<Claim>()                 {                     new Claim("account", userModel.Account),                     new Claim("username", userModel.Username),                     new Claim("sex", userModel.Sex),                     new Claim("birthDate",string.IsNullOrEmpty(userModel.BirthDate)?"":userModel.BirthDate),                     new Claim("email", string.IsNullOrEmpty(userModel.Email)?"":userModel.Email),                     new Claim("sign", string.IsNullOrEmpty(userModel.Sign)?"":userModel.Sign),                     new Claim("phone",string.IsNullOrEmpty(userModel.Phone)?"":userModel.Phone),                     new Claim("headPhoto", string.IsNullOrEmpty(userModel.HeadPhoto)?"":userModel.HeadPhoto)                 };             string jwtToken = new JWT(_cacheClient).CreateToken(claims);             return ApiResult.Success(jwtToken);         }

7,前端存储token
qq登录后根据你申请里面写的回调页面,qq会自动跳转到这个页面,我的回调页面就一个空白页面,加上一个loading提示,加载这个页面时,调用后端api,进行认证操作,成功后,存入token并且跳转到网站首页:

<!DOCTYPE html> <html>  <head>     <meta name="viewport" content="width = device-width" />     <title>qq认证登录中...</title>     <link rel="icon" href="/style/images/title.png"> </head>  <body>     <div>         qq认证登录中...     </div>     <script src="/style/js/jquery.js"></script>     <script src="/style/layui/layui.js"></script>     <script src="/style//js/request.js?v=20112171144"></script>     <script src="/style/js/util.js?v=202009091015"></script>     <script>         layui.use(["layer"], function () {             var layer = layui.layer;             var loading = layer.load(2,{offset: ['100px', '720px']});             var code = getSearchString('code');             if(code==undefined){                 layer.msg('code无效', { icon: 5 });                 return;             }             $.ajax({                 url: url + 'qq/login/' + code,                 type: 'get',                 dataType: 'json',                 success: function (res) {                     if (res.code == "200") {                         localStorage.setItem("token", res.data);                         window.location.href = "../home/index.html";                     }                     else {                         layer.close(loading)                         layer.msg(res.message, { icon: 5 });                     }                 }             })         })     </script> </body>  </html>

通过以上操作,我的个人站点:http://www.ttblog.site已经是完成了qq接入的功能,这只是我自己摸索出来的实现方式,给以参考,设计之中难免有不合理之处,希望有人能给出建议。
