導入ics到谷歌日曆使用caldav

我無法設法導入ics文件到谷歌。我搜索了日曆apis。他們顯然沒有實現它。然後我嘗試了Google caldav（它缺少99％的文檔）。導入ics到谷歌日曆使用caldav

我寫了這個示例函數，它失敗了，出現錯誤400錯誤請求。

private void TestGoogleCaldav() 
    { 
     string contents = string.Empty; 
     string downloadURL = string.Format("https://apidata.googleusercontent.com/caldav/v2/<email>/events/dav.ics"); 
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(downloadURL)); 
     request.Method = "PUT"; 
     request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate; 
     request.ContentType = "application/x-www-form-urlencoded"; 
     request.KeepAlive = true; 
     request.Timeout = 15 * 60 * 1000; 

     string headervalue = string.Empty; 
     string[] scope = new string[] { CalendarService.Scope.Calendar }; 
     string token = GetOauthAccessToken(scope); 
     headervalue = string.Format("Authorization: Bearer {0}", token); 
     request.Headers.Add(headervalue); 

     string iCalFileName = @"C:\temp\invite.ics"; 
     System.IO.StreamReader myFile = new System.IO.StreamReader(iCalFileName); 
     string myString = myFile.ReadToEnd(); 
     var bytes = Encoding.ASCII.GetBytes(myString); 

     using (var requestStream = request.GetRequestStream()) 
     { 
      requestStream.Write(bytes, 0, bytes.Length); 
     } 
     var response = (HttpWebResponse)request.GetResponse(); 

     if (response.StatusCode == HttpStatusCode.OK) 
     { 
     } 
     else 
     { 

     } 
    }

ICS有效且沒有損壞。（由Google在發送給外部用戶時生成）。

「ICS有效且沒有損壞（發送給外部用戶時由Google生成）」。那麼，這是一個iTIP請求（METHOD：REQUEST），而不是一個常規的CalDAV有效載荷。另外，ASCII？真？ – hnh

我打開試圖導入一個常規calDAV有效載荷。你有鏈接到測試嗎？（注意：這個文件導入交換和亞馬遜工作郵箱）。 – CloudAnywhere

只需使用Charles或類似工具從iCal中捕獲一個。 – hnh
