 使用 System.Web; 
 使用 System.Web.UI; 
 使用 System.Web.UI.WebControls; 
 使用 DotNetOpenAuth.OAuth2; 
 使用 Limilabs.Client.Authentication.Google; 
 使用 Google.Apis.Authentication.OAuth2.DotNetOpenAuth; 
 使用 System.Diagnostics;

  public   const   string  OutOfBandCallbackUrl =   http：// localhost：1500 / new_google_tasks / NewDefault.aspx; 
 受保护  void  Page_Load（ object  sender，EventArgs e）

}; 
 
 List< string> scope =  new 列表< string> 
 {
   https://www.googleapis.com/auth/tasks 
 
}; 
 
  if （Request.QueryString.Count >   0 ）
 {
  if （！string.IsNullOrEmpty（Request.QueryString [  code]））
 {
 WebServerClient consumer =  new  WebServerClient（server1，clientID，clientSecret）; 
 consumer.ClientIdentifier = clientID; 
 consumer.ClientSecret = clientSecret; 
  //   consumer.ClientCredentialApplicator =  
  //   ClientCredentialApplicator.PostParameter（clientSecret）;  
 IAuthorizationState grantedAccess = consumer.ProcessUserAuthorization（空）; 
 
  string  accessToken = grantedAccess.AccessToken; 
 
会话[  AccessToken] = accessToken; 
 HttpWebRequest request =（HttpWebRequest）WebRequest.Create（  https://www.googleapis.com/tasks / v1 / users / @ me / lists？key = + accessToken）; 
 ASCIIEncoding encoding =  new  ASCIIEncoding（）; 
 
 request.Method =  发布; 
 request.Headers.Add（ 授权，  Bearer + grantedAccess.AccessToken）; 
 
 HttpWebResponse response =（HttpWebResponse）request.GetResponse（）; 
 GoogleApi api =  new  GoogleApi（accessToken）; 
} 
} 
  else  
 {
 WebServerClient consumer =  new  WebServerClient（server1，clientID，clientSecret）; 
 
 consumer.RequestUserAuthorization（范围，  online， new  Uri（  http：// localhost：1500 / new_google_tasks / NewDefault。 ASPX））; 
 
 
 WebServerClient consumer1 =  new  WebServerClient（server1，clientID，clientSecret）; 
} 
} 
} 

在线上获取错误

 HttpWebResponse response =（HttpWebResponse）request.GetResponse（）; 

即远程服务器返回错误：（411）所需长度。

我正在处理谷歌任务。 PLZ帮助我弄错了。

解决方案

@Tadit Dash现在得到不同的错误

远程服务器返回错误：（403）禁止的。
