Google日历身份验证错误

Question

我正尝试通过最新的Google Data API SDK更新Google日历。

我的示例代码如下：

  string sGoogleUserName = "xxxx@gmail.com"; 
      string sGooglePassword = "xxxxxxxx"; 
      Uri oCalendarUri = new Uri("http://www.google.com/calendar/feeds/" + 
             sGoogleUserName + "/private/full"); 

      //Initialize Calendar Service 
      CalendarService oCalendarService = new CalendarService("CalendarSampleApp"); 
      oCalendarService.setUserCredentials(sGoogleUserName, sGooglePassword); 

      //Use Proxy 
      GDataRequestFactory oRequestFactory = 
       (GDataRequestFactory)oCalendarService.RequestFactory; 
      WebProxy oWebProxy = new WebProxy(
       WebRequest.DefaultWebProxy.GetProxy(oCalendarUri)); 
      oWebProxy.Credentials = CredentialCache.DefaultCredentials; 
      oWebProxy.UseDefaultCredentials = true; 
      oRequestFactory.Proxy = oWebProxy; 


      //Set Event Entry 
      EventEntry oEventEntry = new EventEntry(); 
      oEventEntry.Title.Text = "Test Calendar Entry From .Net"; 
      oEventEntry.Content.Content = 
       "Hurrah!!! I posted my first Google calendar event through .Net"; 

      //Set Event Location 
      Where oEventLocation = new Where(); 
      oEventLocation.ValueString = "New Zealand"; 
      oEventEntry.Locations.Add(oEventLocation); 

      //Set Event Time 
      When oEventTime = new When(new DateTime(2011, 5, 31, 9, 0, 0), 
       new DateTime(2011, 5, 31, 9, 0, 0).AddHours(1)); 
      oEventEntry.Times.Add(oEventTime); 

      //Set Additional Properties 
      ExtendedProperty oExtendedProperty = new ExtendedProperty(); 
      oExtendedProperty.Name = "SynchronizationID"; 
      oExtendedProperty.Value = Guid.NewGuid().ToString(); 
      oEventEntry.ExtensionElements.Add(oExtendedProperty); 

      // CalendarService oCalendarService = GAuthenticate(); 

      //Prevents This Error 
      //{"The remote server returned an error: (417) Expectation failed."} 
      System.Net.ServicePointManager.Expect100Continue = false; 

      //Save Event 
      oCalendarService.Insert(oCalendarUri, oEventEntry); 
     } 
     catch (Exception ex) 
     { 
      MessageBox.Show(ex.ToString()); 
     } 

这里是下面的错误

Google.GData.Client.GDataRequestException：在 Google.GData 405：认证 执行请求返回意外的结果.Client.Utilities.getAuthException（TokenCollection标记， HttpWebResponse响应）在 Google.GData.Client.Utilities.QueryClientLoginToken（GDataCredentials GC，弦乐服务名，字符串的applicationName，布尔fUseKeepAlive， IWebProxy访问代理服务器，乌里clientLoginHandler）在 Google.GData.Client.GDataGAuthRequest.QueryAuthToken（在 谷歌在Google.GData.Client.GDataGAuthRequest.EnsureCredentials GDataCredentials GC）（） .GData.Client.GDataRequest.EnsureWebRequest（）at Google.GData.Client.GDataGAuthRequest.EnsureWebRequest（）at Google.GData.Client.GDataGAuthRequest.CopyRequestData（）at Google.GData.Client.GDataGAuthRequest.Execute（Int32 retryCounter ）at Google.GData.Client.GDataGAuthRequest.Execute（）at Google.GData.Client.Service.EntrySend（Uri feedUri，AtomBase baseEntry， GDataRequestType type，AsyncSendData data）at Google.GData.Client.Service.Insert（URI feedUri，AtomEntry newEntry， AsyncSendData数据）在Google.GData.Client.Service.Insert [TEntry]（URI feedUri，TEntry条目）

再试与版本3.5.12。也许你背后的代理，需要设置 适当的代理设置第一

Answer 2

我今天打这一个，使用相同的示例代码，你做了，我发现在网上的某个地方。

通过一些测试，我发现如果我设置了一个HTTP代理（我使用的是Charles，但其他常见的代理是Fiddler等），但如果我没有使用代理尝试的话，它就会工作。

在一种预感，我注释掉的东西下//使用代理这样的，它的工作：

string googleUserName = "falagard@gmail.com"; 
string googlePassword = "winnie"; 
Uri calendarUri = GetGoogleCalendarUri(); 

//Initialize Calendar Service 
CalendarService service = new CalendarService("AIConsole"); 
service.setUserCredentials(googleUserName, googlePassword); 

//Use Proxy - NOTE COMMENTED THIS PART OUT 
//GDataRequestFactory requestFactory = (GDataRequestFactory)service.RequestFactory; 
//WebProxy proxy = new WebProxy(WebRequest.DefaultWebProxy.GetProxy(calendarUri)); 
//proxy.Credentials = CredentialCache.DefaultCredentials; 
//proxy.UseDefaultCredentials = true; 
//requestFactory.Proxy = proxy; 

之后，它的工作就像一个魅力。
