JSON调用时请求超时错误

Question

我用 Newtonsoft 创建了一个 JSON 对象。当我想将它传递给 RESTful Web 服务并希望从中响应时，我收到“请求超时”错误，尽管我将请求的超时设置为 -1 或任何值。问题出在哪里？

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://app.myservice.com/sendJSon");
    request.ContentType = "text/json";
    request.Method = "POST";
    request.Timeout = 200000;

    JObject asnInfo = CreateAsnInfo();

    JsonSerializer serializer = new JsonSerializer();
    using (var streamWriter = new StreamWriter(request.GetRequestStream()))
    {
        using (var writer = new JsonTextWriter(streamWriter))
        {
            serializer.Serialize(writer, asnInfo);
        }
    }
    var response = (HttpWebResponse)request.GetResponse();
    using (var streamReader = new StreamReader(response.GetResponseStream()))
    {
        var responseText = streamReader.ReadToEnd();
    }

你在代理后面吗？该代码似乎适用于公共测试网络服务。
