推荐答案

在Web API的一面，简单地使用，而不是创建Request对象的新的Htt prequestMessage

On the Web API side, simply use Request object instead of creating new HttpRequestMessage

     var re = Request;
    var headers = re.Headers;

    if (headers.Contains("Custom"))
    {
        string token = headers.GetValues("Custom").First();
    }

    return null;
