AbpZero之企业微信登录（拓展第三方auth授权登录）第三步：需要注意事项

1、AbpZero的auth登录会在数据库中的AbpUserLogins表会根据你登录的ProviderKey和Provider来生成生成一条记录，ProviderKey在表中是唯一的；

2、要登录成功还得重写下TokenAuthController.cs下的GetExternalUserInfo方法，代码如下

  private async Task<ExternalAuthUserInfo> GetExternalUserInfo(ExternalAuthenticateModel model)
        {
            var userInfo = await _externalAuthManager.GetUserInfo(model.AuthProvider, model.ProviderAccessCode);
            //if (userInfo.ProviderKey != model.ProviderKey)
            //{
            //    throw new UserFriendlyException(L("CouldNotValidateExternalUser"));
            //}

            return userInfo;
        }

3、由于我公司需要集成企业微信，小程序，钉钉等登录，但用户的唯一值都是一样的，所以我们也重写了ExternalAuthenticate方法，代码如下

   [HttpPost]
        public async Task<ExternalAuthenticateResultModel> WeChatAuthenticate([FromBody] ExternalAuthenticateModel model)
        {
            var externalUser = await GetExternalUserInfo(model);

            //Logger.Debug(Newtonsoft.Json.JsonConvert.SerializeObject(new UserLoginInfo(model.AuthProvider, externalUser.ProviderKey, model.AuthProvider) ) + GetTenancyNameOrNull());
            var loginResult = await _logInManager.LoginAsync(new UserLoginInfo(model.AuthProvider, externalUser.ProviderKey, model.AuthProvider), GetTenancyNameOrNull());
            //Logger.Debug(loginResult.Result.ToString());
            switch (loginResult.Result)
            {
                case AbpLoginResultType.Success:
                    {
                        var accessToken = CreateAccessToken(CreateJwtClaims(loginResult.Identity));

                        var returnUrl = model.ReturnUrl;

                        if (model.SingleSignIn.HasValue && model.SingleSignIn.Value && loginResult.Result == AbpLoginResultType.Success)
                        {
                            loginResult.User.SetSignInToken();
                            returnUrl = AddSingleSignInParametersToReturnUrl(model.ReturnUrl, loginResult.User.SignInToken, loginResult.User.Id, loginResult.User.TenantId);
                        }
                        return new ExternalAuthenticateResultModel
                        {
                            AccessToken = accessToken,
                            EncryptedAccessToken = GetEncrpyedAccessToken(accessToken),
                            ExpireInSeconds = (int)_configuration.Expiration.TotalSeconds,
                            ReturnUrl = returnUrl
                        };
                    }
                case AbpLoginResultType.UnknownExternalLogin:
                    {
                        var newUser = await RegisterExternalUserAsync(externalUser);
                        if (!newUser.IsActive)
                        {
                            return new ExternalAuthenticateResultModel
                            {
                                WaitingForActivation = true
                            };
                        }

                        //Try to login again with newly registered user!
                        loginResult = await _logInManager.LoginAsync(new UserLoginInfo(model.AuthProvider, externalUser.ProviderKey, model.AuthProvider), GetTenancyNameOrNull());
                        if (loginResult.Result != AbpLoginResultType.Success)
                        {
                            throw _abpLoginResultTypeHelper.CreateExceptionForFailedLoginAttempt(
                                loginResult.Result,
                                model.ProviderKey,
                                GetTenancyNameOrNull()
                            );
                        }

                        var accessToken = CreateAccessToken(CreateJwtClaims(loginResult.Identity));
                        return new ExternalAuthenticateResultModel
                        {
                            AccessToken = accessToken,
                            EncryptedAccessToken = GetEncrpyedAccessToken(accessToken),
                            ExpireInSeconds = (int)_configuration.Expiration.TotalSeconds
                        };
                    }
                default:
                    {
                        throw _abpLoginResultTypeHelper.CreateExceptionForFailedLoginAttempt(
                            loginResult.Result,
                            model.ProviderKey,
                            GetTenancyNameOrNull()
                        );
                    }
            }
        }
