在这篇答案中，我描述了如何在HttpWebResponse中的响应流上包装一个GZipStream来进行解压缩。
相关的代码如下：
HttpWebRequest hwr = (HttpWebRequest) WebRequest.Create(url);
hwr.CookieContainer =
PersistentCookies.GetCookieContainerForUrl(url);
hwr.Accept = "text/xml, */*";
hwr.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate");
hwr.Headers.Add(HttpRequestHeader.AcceptLanguage, "en-us");
hwr.UserAgent = "My special app";
hwr.KeepAlive = true;
using (var resp = (HttpWebResponse) hwr.GetResponse())
{
using(Stream s = resp.GetResponseStream())
{
Stream s2 = s;
if (resp.ContentEncoding.ToLower().Contains("gzip"))
s2 = new GZipStream(s2, CompressionMode.Decompress);
else if (resp.ContentEncoding.ToLower().Contains("deflate"))
s2 = new DeflateStream(s2, CompressionMode.Decompress);
... use s2 ...
}
}
有没有一种方法可以让HttpWebResponse自动提供解压缩流？换句话说，有没有一种方法可以让我从上面的代码中消除以下内容：
Stream s2 = s;
if (resp.ContentEncoding.ToLower().Contains("gzip"))
s2 = new GZipStream(s2, CompressionMode.Decompress);
else if (resp.ContentEncoding.ToLower().Contains("deflate"))
s2 = new DeflateStream(s2, CompressionMode.Decompress);
谢谢。
