Question

大家好我正在尝试使用silverlight 5发送getasync请求。后期异步工作没有任何问题，但getasync在添加授权标头时抛出该异常。当没有添加授权头时，这只是401。我该怎么做才能解决它？

代码：

    client.DefaultRequestHeaders.Add("Authorization", "Bearer secrettoken");

var getasynctask = await client.GetAsync("http://api.enteroption.com/api/UserDetails/GetUserIdByToken/");

例外：

System.ArgumentException occurred
  Message=""
  StackTrace:

       at Microsoft.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccess(Task task)

       at Microsoft.Runtime.CompilerServices.TaskAwaiter`1.GetResult()
       at ConsoleApplication3.Class1.<Func>d__1.MoveNext()
  InnerException: System.ArgumentException
       Message=Value does not fall within the expected range.

我知道这已经很晚了，但我挣扎了很长一段时间，这让我的脑袋绕错了方向......但最终我做了以下的工作，这真的让我很烦恼，这就是问题

  client.DefaultRequestHeaders.Add("Authorization", "Bearer " + kvp.Value);
  //client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", kvp.Value );
