Question

以下是该方案。我编写的代码使用数字证书从安全URL获取cookie，然后使用检索到的cookie和相同的数字证书将数据POST回到另一个URL。 GET工作和cookie被检索，POST返回错误500.我安装了fiddler以查看发生了什么... POST看起来很好......存在cookie。我在fiddler中使用了该功能，允许通过拖放创建请求。发布从fiddler中记录的C＃代码记录的完全相同的POST，它可以工作！

Fiddler做的那个Visual Studio不是什么？如果fiddler可以POST数据但Visual Studio返回错误500，它必须做一些事情。这是下面的代码：

X509Certificate cert = new X509Certificate("mycert.pfx", "certpassword");
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://servertoGETcookies/fileUpload.html");
req.CookieContainer = new CookieContainer();
req.Method = "GET";
req.ClientCertificates.Add(cert);

HttpWebResponse Response = (HttpWebResponse)req.GetResponse();
CookieCollection ck = req.CookieContainer.GetCookies(req.RequestUri);
string strcookie = ck[0].Value;
string strcookie2 = ck[1].Value;
Response.Close();

req = (HttpWebRequest)WebRequest.Create("https://servertoPOSTdatawithcookies/main");
req.CookieContainer = new CookieContainer();
Cookie auth = new Cookie("_wl_authcookie_", strcookie2);
Cookie jsess = new Cookie("JSESSIONID", strcookie);
auth.Domain = "server";
jsess.Domain = "server";
req.CookieContainer.Add(auth);
req.CookieContainer.Add(jsess);
req.ClientCertificates.Add(cert);
req.Method = "POST";

Byte[] data = ReadByteArrayFromFile("filewithdatatoPOST.txt");
req.ContentLength = data.Length;
Stream myStream = req.GetRequestStream();
myStream.Write(data, 0, data.Length);
myStream.Close();

HttpWebResponse Response2 = (HttpWebResponse)req.GetResponse();
Stream strm = Response2.GetResponseStream();
StreamReader sr2 = new StreamReader(strm);
Response2.Close();

Answer 1

如果设置

，您的代码是否有效

req.ServicePoint.Expect100Continue = false;

在您的所有WebRequests上？

Answer 2

解决!!!它与Expect100Continue无关。

经过数周的故障排除...... 6位不同的程序员......我想通了。我不确定这是否总是如此，但在这种情况下问题是我们从以下网址获取cookie：

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://servertoGETcookies/fileUpload.html");

与我们将数据发回的网址不同：

req = (HttpWebRequest)WebRequest.Create("https://servertoPOSTdatawithcookies/main");

获取Cookie并回发到相同的网址可以解决问题：

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://servertoGETandPOSTcookies/main");
req = (HttpWebRequest)WebRequest.Create("https://servertoGETandPOSTcookies/main");

HttpWebRequest到https服务器在fiddler中工作但不在Visual Studio中工作
