Question

我一直在收到像这样的垃圾文本

�\b\0\0\0\0\0\0�\a`I�%&/m�{J�J��t�\b�`$ؐ@������iG#

在此函数末尾的html变量中。正如您所看到的，通过注释掉的代码，我尝试了两种插入Cookie的方法。

我是这样的HTTPwebRequest / Response方法的新手。但是从我在网上找到的所有内容中，我正确地设置了我的方法。如果可能，我会很乐意帮助。

此外，当使用Fiddler解码我的请求时，并非我的所有cookie都被发送。我的代码运行时，我只发送1 utma，1 utmb，1 utmc和1 utmz。但是，当我正常登录网站时，我会收到2个utma，1个utmb，2个utmc和2个utmz。

我觉得这是我连接问题的根源，但我不确定。

static void FillCookieJar()
{
    Console.WriteLine("Filling cookie jar...\r\n");
    try
    {
        string parameters = "SUPER LONG POST DATA found from TEXTVIEW in Fidler";
        Uri target = new Uri("https://foo.bar.com/UserSignIn");

        byte[] buffer = Encoding.ASCII.GetBytes(parameters);

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(target);

        //Cookie chipOne = new Cookie("__utma", "XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XX") { Domain = target.Host };
        //Cookie chipTwo = new Cookie("__utma", "XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.X") { Domain = target.Host };
        //Cookie chipThree = new Cookie("__utmb", "XXXXXXXXX.X.XX.XXXXXXXXX") { Domain = target.Host };
        //Cookie chipFour = new Cookie("__utmc", "XXXXXXXXX") { Domain = target.Host };
        //Cookie chipFive = new Cookie("__utmc", "XXXXXXXXX") { Domain = target.Host };
        //Cookie chipSix = new Cookie("__utmz", "XXXXXXXXX.XXXXXXXXX.X.X.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=(not%20provided)") { Domain = target.Host };
        //Cookie chipSeven = new Cookie("__utmz", "XXXXXXXXX.XXXXXXXXX.XX.X.utmcsr=titlesource.com|utmccn=(referral)|utmcmd=referral|utmcct=/") { Domain = target.Host };

        //cookieJar.Add(chipOne);
        //cookieJar.Add(chipTwo);
        //cookieJar.Add(chipThree);
        //cookieJar.Add(chipFour);
        //cookieJar.Add(chipFive);
        //cookieJar.Add(chipSix);
        //cookieJar.Add(chipSeven);

        request.Headers.Add("__utma", "XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XX");
        request.Headers.Add("__utma", "XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.XXXXXXXXX.X");
        request.Headers.Add("__utmb", "XXXXXXXXX.X.XX.XXXXXXXXX");
        request.Headers.Add("__utmc", "XXXXXXXXX");

        request.Headers.Add("__utmz", "XXXXXXXXX.XXXXXXXXX.XX.X.utmcsr=titlesource.com|utmccn=(referral)|utmcmd=referral|utmcct=/");

        request.CookieContainer = cookieJar;
        request.Method = WebRequestMethods.Http.Post;
        request.KeepAlive = true;
        request.Accept = "*/*";
        request.Headers.Add("Cache-Control", "no-cache");
        request.Headers.Add("Accept-Encoding: gzip,deflate,sdch");
        request.Headers.Add("Accept-Language: en-US,en;q=0.8");
        request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36";
        request.Headers.Add("X-Requested-With: XMLHttpRequest");
        request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
        request.Referer = "https://foo.bar.com/UserSignIn";
        request.Headers.Add("Origin", "https://foo.bar.com");
        request.Headers.Add("X-MicrosoftAjax", "Delta=true");
        request.ContentLength = buffer.Length;

        Stream PostData = request.GetRequestStream();
        PostData.Write(buffer, 0, buffer.Length);
        PostData.Close();

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        Stream Answer = response.GetResponseStream();
        StreamReader _Answer = new StreamReader(Answer);
        String html = _Answer.ReadToEnd();
        response.Close();

    }
    catch (Exception ex)
    {
        Console.WriteLine("Error FillingCookieJar");
    }
}

您需要解压缩gzip流以获取纯文本，这可能是UTF-8而不是ASCII（在响应的charset标题中查找Content-Type属性）。

您可以使用AutomaticDecompression属性自动解压缩内容。

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(target);
request.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip;

您看到的网址是UrlEncoded。您可以使用HttpUtility.UrlDecode将网址设为https://foo.bar.com/Vendor。

string decoded = HttpUtility.UrlDecode(html);

GetResponseStream（）中的垃圾文本
