当请求具有Gzip压缩的页面时,我收到了很多以下错误:

System.IO.InvalidDataException:GZip页脚中的CRC与从解压缩数据计算的CRC不匹配

我正在使用本机GZipStream进行解压缩,正在寻找解决此问题的方法.考虑到这一点,是否有解决这个或另一个GZip库(免费？)的工作,它将正确处理这个问题？

我正在验证webResponse ContentEncoding是否为GZIP

更新5/11 简化的snippit

//Caller
public void SOSampleGet(string url) 
{
    // Initialize the WebRequest.
    webRequest = (HttpWebRequest)WebRequest.Create(url);
    webRequest.Method = WebRequestMethods.Http.Get;
    webRequest.KeepAlive = true;
    webRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
    webRequest.Headers.Add("Accept-Encoding", "gzip,deflate");
    webRequest.Referer = WebUtil.GetDomain(url);

    HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse();    

    using (Stream stream = GetStreamForResponse(webResponse, READTIMEOUT_CONST))
    {
        //use stream
    }
}

//Method
private static Stream GetStreamForResponse(HttpWebResponse webResponse, int readTimeOut)
{
    Stream stream;
    switch (webResponse.ContentEncoding.ToUpperInvariant())
    {
        case "GZIP":
            stream = new GZipStream(webResponse.GetResponseStream(), CompressionMode.Decompress);
            break;
        case "DEFLATE":
            stream = new DeflateStream(webResponse.GetResponseStream(), CompressionMode.Decompress);
            break;

有没有一种快速方法来解压缩使用WebClient.DownloadString()方法下载的gzip响应？您对如何使用WebClient处理gzip响应有任何建议吗？

想要解压缩从 API 获取的 GZipped 响应。尝试了下面的代码，它总是返回类似：-

\\u001f\xef\xbf\xbd\\b\\0\\0\\0\\0\\0\\0\\0\xef\xbf\xbdY]o........\n

我的代码是：

 private string GetResponse(string sData, string sUrl)\n {\n      try\n      {\n           string script = null;\n           try\n           {\n                string urlStr = @"" + sUrl + "?param=" + sData;\n\n                Uri url = new Uri(urlStr, UriKind.Absolute);\n\n                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);\n                request.Method = "GET";\n                request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;\n\n                using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())\n                using (StreamReader reader = new StreamReader(response.GetResponseStream()))\n                {\n                     script = reader.ReadToEnd();\n                }      \n           }\n           catch (System.Net.Sockets.SocketException)\n           {\n                // The remote site is currently …

我有这段代码可以从 URL 获取页面 HTML，但是响应内容看起来是经过编码的。

代码：

    HttpWebRequest xhr = (HttpWebRequest) WebRequest.Create(new Uri("https://www.youtube.com/watch?v=_Ewh75YGIGQ"));
        xhr.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
        //xhr.CookieContainer = request.Account.CookieContainer;
        xhr.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
        xhr.Headers["Accept-Encoding"] = "gzip, deflate, br";
        xhr.Headers["Accept-Language"] = "en-US,en;q=0.5";
        xhr.Headers["Upgrade-Insecure-Requests"] = "1";
        xhr.KeepAlive = true;
        xhr.UserAgent = "Mozilla/4.0 (compatible; MSIE 9.0; Windows NT 6.1)";
        xhr.Host = "www.youtube.com";
        xhr.Referer = "https://www.youtube.com/watch?v=6aCpYxzRkf4";
        var response = xhr.GetResponse();
        string html;
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            html = reader.ReadToEnd();
        }

这些是响应标头：
