补充ABP Zero集成微信小程序登陆的BUG修复部分

感谢园友 @turingguo 发布的 https://www.cnblogs.com/turingguo/p/9019026.html  文章，详细介绍了ABP Zero集成微信小程序登陆的实现过程。

经测试，abp的外部登陆有几处bug，在此做记录。

1、xxxxWebHostModule.cs文件

 1         public override void PostInitialize()
 2         {
 3
 4             if (!IocManager.Resolve<IMultiTenancyConfig>().IsEnabled)
 5             {
 6                 return;
 7             }
 8
 9             if (!DatabaseCheckHelper.Exist(_appConfiguration["ConnectionStrings:Default"]))
10             {
11                 return;
12             }
13
14             var workManager = IocManager.Resolve<IBackgroundWorkerManager>();
15             workManager.Add(IocManager.Resolve<SubscriptionExpirationCheckWorker>());
16             workManager.Add(IocManager.Resolve<SubscriptionExpireEmailNotifierWorker>());
17
18             ConfigureExternalAuthProviders();
19         }

当启用多租户模式的情况下，租主站点没有将外部登陆的provider添加到集合中。

不未启用多租户模式时，第四行的逻辑判断又给跳过了。

因此将18行代码调整到第3行。

2、TokenAuthController文件

 1 public async Task<ExternalAuthenticateResultModel> ExternalAuthenticate([FromBody] ExternalAuthenticateModel model)
 2         {
 3             var externalUser = await GetExternalUserInfo(model);
 4
 5             var loginResult = await _logInManager.LoginAsync(new UserLoginInfo(model.AuthProvider, externalUser.ProviderKey, model.AuthProvider), GetTenancyNameOrNull());
 6
 7             switch (loginResult.Result)
 8             {
 9                 case AbpLoginResultType.Success:
10                     {
11                         var accessToken = CreateAccessToken(CreateJwtClaims(loginResult.Identity));
12
13                         var returnUrl = model.ReturnUrl;
14
15                         if (model.SingleSignIn.HasValue && model.SingleSignIn.Value && loginResult.Result == AbpLoginResultType.Success)
16                         {
17                             loginResult.User.SetSignInToken();
18                             returnUrl = AddSingleSignInParametersToReturnUrl(model.ReturnUrl, loginResult.User.SignInToken, loginResult.User.Id, loginResult.User.TenantId);
19                         }
20
21                         return new ExternalAuthenticateResultModel
22                         {
23                             AccessToken = accessToken,
24                             EncryptedAccessToken = GetEncrpyedAccessToken(accessToken),
25                             ExpireInSeconds = (int)_configuration.Expiration.TotalSeconds,
26                             ReturnUrl = returnUrl
27                         };
28                     }
29                 case AbpLoginResultType.UnknownExternalLogin:
30                     {
31                         var newUser = await RegisterExternalUserAsync(externalUser);
32                         if (!newUser.IsActive)
33                         {
34                             return new ExternalAuthenticateResultModel
35                             {
36                                 WaitingForActivation = true
37                             };
38                         }
39
40                         //Try to login again with newly registered user!
41                         loginResult = await _logInManager.LoginAsync(new UserLoginInfo(model.AuthProvider, externalUser.ProviderKey, model.AuthProvider), GetTenancyNameOrNull());
42                         if (loginResult.Result != AbpLoginResultType.Success)
43                         {
44                             throw _abpLoginResultTypeHelper.CreateExceptionForFailedLoginAttempt(
45                                 loginResult.Result,
46                                 model.ProviderKey,
47                                 GetTenancyNameOrNull()
48                             );
49                         }
50
51                         var accessToken = CreateAccessToken(CreateJwtClaims(loginResult.Identity));
52                         return new ExternalAuthenticateResultModel
53                         {
54                             AccessToken = accessToken,
55                             EncryptedAccessToken = GetEncrpyedAccessToken(accessToken),
56                             ExpireInSeconds = (int)_configuration.Expiration.TotalSeconds
57                         };
58                     }
59                 default:
60                     {
61                         throw _abpLoginResultTypeHelper.CreateExceptionForFailedLoginAttempt(
62                             loginResult.Result,
63                             model.ProviderKey,
64                             GetTenancyNameOrNull()
65                         );
66                     }
67             }
68         }

分别在第5行和41行，是用户外部登陆的过程。该两行代码的BUG是，登陆时使用了微信的accessCode当作providerKey登陆，方法是将 await GetExternalUserInfo(model) 返回的ProviderKey做为用户登陆就可以了。(以上代码是修改后的代码)
