从WebClient解压缩gzip响应

从WebClient解压缩gzip响应

最简单的方法是对该类使用内置的自动解压缩功能

HttpWebRequest

。

var request = (HttpWebRequest)HttpWebRequest.Create("http://stackoverflow.com");request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate");request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

为此，

WebClient

您必须使自己的类派生

WebClient

并覆盖该

GetWebRequest()

方法。

public class GZipWebClient : WebClient{    protected override WebRequest GetWebRequest(Uri address)    {        HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(address);        request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;        return request;    }}
