dotnetOpenAuth 因协议错误而失败。是 ServiceProviderDescription 还是 TokenManager？

Question

为什么我会得到openAuth protocol error？

{"远程服务器返回错误：(400) Bad Request."}

在 System.Net.HttpWebRequest.GetResponse() 在 DotNetOpenAuth.Messaging.StandardWebRequestHandler.GetResponse(HttpWebRequest 请求，DirectWebRequestOptions 选项）在 c:\BuildAgent\work\a02b428f36957bca\src\DotNetOpenAuth\Messaging\StandardWebRequestHandler.cs:line 126

    public static readonly ServiceProviderDescription ServiceDescription = new  ServiceProviderDescription
{
    RequestTokenEndpoint = 
       new MessageReceivingEndpoint("https://www.google.com/account/OAuthGetRequestToken", HttpDeliveryMethods.AuthorizationHeaderRequest | HttpDeliveryMethods.GetRequest),
    UserAuthorizationEndpoint = 
       new MessageReceivingEndpoint("https://www.google.com/accounts/OAuthAuthorizeToken",
HttpDeliveryMethods.AuthorizationHeaderRequest | HttpDeliveryMethods.GetRequest),
    AccessTokenEndpoint = 
       new MessageReceivingEndpoint("https://www.google.com/accounts/OAuthGetAccessToken", HttpDeliveryMethods.AuthorizationHeaderRequest | HttpDeliveryMethods.GetRequest),
    TamperProtectionElements = 
       new ITamperProtectionChannelBindingElement[] { new HmacSha1SigningBindingElement() },
  };



public void StartOAuth()
{
    var consumer = new WebConsumer(GoogleConsumer.ServiceDescription, new InMemoryTokenManager("user", "pass"));
 // Url to redirect to
    var authUrl = new Uri("http://www.google.com");
 // request access
    consumer.Channel.Send(consumer.PrepareRequestUserAuthorization(authUrl, null, null));

      throw new NoRedirectToAuthPageException();
     }

我不知道这是否会导致您看到的错误，但是您将 Google 自己的 URL 作为回调 URL 传入？这似乎是错误的。您需要将 URL 传递给您自己的站点（将调用 WebConsumer.ProcessUserAuthorization 的站点）作为 PrepareRequestUserAuthorization 方法的第一个参数。

我还注意到您的请求令牌 URL 中缺少一个“s”：https://www.google.com/account*s*/OAuthGetRequestToken

这很可能会破坏它。
