HttpClient GetStreamAsync和HTTP状态代码? [英] HttpClient GetStreamAsync and HTTP status codes?

问题描述

我希望使用 json.net性能提示文档推荐的流，但是如果没有

I wish to use streams as recommended by the json.net performance tips documentation, however I'm unable to find how to get a hold of the http status codes without the typical awaiting the HttpResponse.

也许有一种不读取数据就先获取状态码的方法吗?所以仍然利用流吗?

Is there perhaps a way of getting the status code first without reading the data? So still taking advantage of streams?

推荐答案

我尚未进行测试以确保其性能，但这似乎很有希望:

I haven't tested to ensure it's performance, however this seems promising:

using(HttpClient client = new HttpClient())
{
    var response = await client.GetAsync("http://httpbin.org/get", HttpCompletionOption.ResponseHeadersRead);

    response.EnsureSuccessStatusCode();

    using (var stream = await response.Content.ReadAsStreamAsync())
    using (var streamReader = new StreamReader(stream))
    using (var jsonReader = new JsonTextReader(streamReader))
    {
      var serializer = new JsonSerializer();

       //do some deserializing http://www.newtonsoft.com/json/help/html/Performance.htm
    }
}
