当我在C#中发出HTTP请求并读取响应时,我在响应中获取了垃圾数据。我无法弄清楚这个问题。请考虑以下示例代码段,其中我调用了Stack Exchange API。
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://api.stackexchange.com/info");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = client.GetAsync("?site=stackoverflow").Result;
if (response.IsSuccessStatusCode)
{
Console.WriteLine(response.Content.ReadAsStringAsync().Result);
}
else
{
Console.WriteLine("Sorry");
}
下面的屏幕截图说明了我收到的垃圾输出:
我非常感谢您尝试调试此问题并了解我出错的地方。

问题是数据被压缩了。
要修复它,无需自行解压缩数据,请指示HttpClient
为您执行此操作:
HttpClientHandler handler = new HttpClientHandler()
{
AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
};
HttpClient client = new HttpClient(handler);
// ... rest of your code here
然后您的代码会提供此输出(缩写):
{"items":[{"new_active_users":13,"total_users":7599686,"badges_per_minute":5.04,"total_badges":24036822,...
这也是documented:
此外,所有API响应都已压缩。
