我正在尝试使用gmail服务读取收件箱数据并将其显示在我的聊天机器人中。我想使用我的Gmail帐户进行身份验证。当我在bot模拟器中测试chatbot可以正常工作时，问题开始于在Web上部署..i无法在Web上进行身份验证。

System.Environment.SpecialFolder.Personal);
using (var stream = new FileStream(jsonPath2, FileMode.Open, FileAccess.Read))

GoogleClientSecrets.Load(stream).Secrets,

编辑：
我尝试在下面添加代码：
var credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new
ClientSecrets
{
ClientId = "xx-
xxxxxxxxx.apps.googleusercontent.com",
ClientSecret = "xxxxxxxxxxxxxxxxxxxxx-lLO"
},
new[] {
GmailService.Scope.GmailReadonly,
GmailService.Scope.MailGoogleCom,
GmailService.Scope.GmailMetadata
},
"user",
CancellationToken.None,
new
FileDataStore("Drive.Auth.Store")).Result;
var gmailService = new Google.Apis.Gmail.v1.GmailService(new
BaseClientService.Initializer()
{
HttpClientInitializer = credential,
});
但是当我尝试上网时，我仍然遇到问题：
错误：redirect_uri_mismatch
请求http://127.0.0.1:52158/authorize/中的重定向URI与为OAuth客户端授权的重定向URI不匹配。要更新授权的重定向URI，请访问：https://console.developers.google.com/apis/credentials/oauthclient/673194113721-45u2pgl6m2l74ecf13c51fmmihrsu3jh.apps.googleusercontent.com?project=673194113721

现在我正在使用此代码。我从机器人那里得到答案，直到： “秘密名称为...” + secrets.ClientId +“ _____和...。” + secrets.ClientSecret +“ ++++令牌为” + token.RefreshToken 但是在尝试阅读电子邮件时停止:(
您能帮我发生什么吗？
答案 0 :(得分：0)
有几种验证Google身份的方法。
您为上述每种身份验证类型创建的客户端都不同。使用它们的代码也不同。
GoogleWebAuthorizationBroker.AuthorizeAsync用于验证已安装的应用程序。它不能与Web应用程序一起使用。
对于Web应用程序，您应该遵循Web applications (ASP.NET MVC)并使用GoogleAuthorizationCodeFlow
private static readonly IAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = "PUT_CLIENT_ID_HERE",
ClientSecret = "PUT_CLIENT_SECRET_HERE"
},
Scopes = new[] { GmailService.Scope.GmailReadonly },
DataStore = new FileDataStore(this.GetType().ToString()
});
redirect_uri_mismatch
为了使用api，您的客户端必须进行核心设置。在Google Developer Console中，您只需要在客户端的设置中添加适当的重定向uri，它就会起作用。它必须与http://127.0.0.1:52158/authorize/完全匹配，以确保Visual Studio不会在您身上创建随机端口号。
