AbpZero之企业微信---登录（拓展第三方auth授权登录）---第二步：开始逐步实现企业微信登录

上回分解到AbpZero的auth登录机制，这里我们开始着手逐步实现我们的auth登录。

我们新建一个类库XXXX.Web.Authentication.External

在类库下新建一个类QYWechatAuthProviderApi.cs并继承ExternalAuthProviderApiBase 由于我用的是盛派的SDK，所以还要在项目Nuget盛派的工程dll

以上就是企业微信登录的代码了。

最后，我们怎么开启企业微信的登录呢？

我们还需要再运行站点下的appsettings.json文件中加上我们企业微信的appid和密钥

 1 "Facebook": {
 2       "IsEnabled": "true",
 3       "AppId": "",
 4       "AppSecret": ""
 5     },
 6     "Google": {
 7       "IsEnabled": "true",
 8       "ClientId": "",
 9       "ClientSecret": ""
10     },
11     "Wechat": {
12       "IsEnabled": "true",
13       "AppId": "xxxx",
14       "Secret": "xxx"
15  
16     },

最后一步：在站点的BanchWebHostModule.cs的ConfigureExternalAuthProviders方法下添加注册

 1  if (bool.Parse(_appConfiguration["Authentication:Wechat:IsEnabled"]))
 2             {
 3                 externalAuthConfiguration.Providers.Add(
 4                     new ExternalLoginProviderInfo(
 5                         WechatAuthProviderApi.Name,
 6                         _appConfiguration["Authentication:Wechat:AppId"],
 7                         _appConfiguration["Authentication:Wechat:Secret"],
 8                         typeof(QYWechatAuthProviderApi)
 9                     )
10                 );
11             }

自此，企业微信登录就完成了，这里主要用到的是依赖注入和反射。
