奇怪的HttpClient结果 [英] Strange HttpClient result

问题描述

当尝试从Hitbox API中获取数据时，我得到了一个奇怪的结果.对于一个API的命令，它每次都会发生，而对于另一个API则有时会发生.结果大致如此(这是我得到的最后结果):

When trying to get data from a Hitbox API I get a strange result. For a one API's command it happens everytime, for the other only sometimes. The result more or less like that (this is the last result I have got):

要长得多，但是复制所有内容(大约30000个字符)毫无意义.

It's much much longer but it's pointless to copy all of it (about 30000 characters).

我用来获取json结果的代码是:

My code that I use to get the json result is:

string result;

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri(hitboxApiLink);
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

    HttpResponseMessage response = client.GetAsync(requestString).Result;
    result = response.Content.ReadAsStringAsync().Result;
}

return result;

我以前曾经用过这个

HttpWebRequest request = (HttpWebRequest) WebRequest.Create(Path.Combine(hitboxApiLink, requestString));
request.KeepAlive = false;
request.ContentType = "application/json; charset=utf-8";
WebResponse response = request.GetResponse();

using(StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
    result = reader.ReadToEnd();
}

它返回相同的结果.但是，当我尝试使用Google Chrome或Internet Explorer获取数据时，它将返回正常结果.该api是: http://developers.hitbox.tv/

And it returns the same. But when I try to get data with Google Chrome or Internet Explorer it returns normal result. The api is: http://developers.hitbox.tv/

我尝试从中获取数据的链接是: https://api.hitbox.tv/媒体/直播/列表

The link I try to get data from is: https://api.hitbox.tv/media/live/list

推荐答案

响应已通过GZIPped处理(即使请求中的Accept-Encoding标头未指定响应，从技术上讲也是服务器故障).

The response is GZIPped (even though this wasn't specified by an Accept-Encoding header in the request, so is technically a fault on the server).

您的第二个示例可以通过在触发请求之前添加以下行来解决:

Your second example can be fixed by adding the following line before you fire off the request:

request.AutomaticDecompression = DecompressionMethods.GZip;

这应该为您提供您需要的一切以了解如何解压缩响应HttpClient版本.

This should give you everything you need to figure out how to decompress the response of the HttpClient version.
