C# GetResponseStream（）中的垃圾文本

我一直收到这样的垃圾短信

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

在我的

html

变量中，在该函数的末尾。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

我对HTTPwebRequest/Response这样的方法非常陌生。但从我在网上所能找到的一切来看，我正在正确地设置我的方法。如果可能的话，我想得到一些帮助

另外，当使用Fiddler解码我的请求时，并不是所有的cookie都被发送。当我的代码运行时，我只发送1个utma、1个utmb、1个utmc和1个utmz。但是，当我正常登录站点时，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 };

您需要解压缩gzip流以获取纯文本，这可能是在

UTF-8

中，而不是在ASCII中（在响应的

内容类型

标题上查找

字符集

属性）

您可以使用该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url是

urlcoded

。您可以使用使URL看起来像

https://foo.bar.com/Vendor

string decoded = HttpUtility.UrlDecode(html);

---

@你将如何调试它？OP已使用Fiddler。您确定编码是

ASCII

而不是

UTF-8

？另外，您确定数据没有被压缩吗？对于后者，可以使用

request.AutomaticDecompression=DecompressionMethods.Deflate | DecompressionMethods.GZip在您的
HttpWebRequest
实例化之后，让类自动为gzip放气。您发现了这两个问题！非常感谢。但是，现在我的
html
变量返回=
1 | | | | | | 4 | 45 |页面重定向| | https%3a%2f%2foo.bar.com%2fVendor |
我能用
1 | | | | | | 4 | 45 |页面重定向做什么||https://foo.bar.com/Vendor|
？我应该在下一个HttpWebRequest方法中将其用作目标URI吗？这取决于您。您从站点返回的数据将根据站点的不同而变化，但上面的信息显示了如何解码流。
