怎么解决https服务调用超时

Answer 1

自己给HttpWebRequest做了些包装，主要是跟其他服务器接口做交互，使用Https协议，封装的类可以在本地正常运行，但是放到服务器上面之后就请求超时，并且同一个服务器上面的WinForm程序能够正常使用这个类，自己写了一个简单的页面做了下测试，本地也是可以正常运行的，服务器上就请求超时，代码如下
protected void Page_Load(object sender, EventArgs e)
{

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate);
HttpWebRequest reqs = (HttpWebRequest)HttpWebRequest.Create("https://123.123.....");

string path= Server.MapPath("~/AppConfig/abc.pfx");

X509Certificate cer = new X509Certificate(path, "123");
reqs.ClientCertificates.Add(cer);
HttpWebResponse resp = (HttpWebResponse)reqs.GetResponse();

StreamReader streamReader = new StreamReader(resp.GetResponseStream());
string str = string.Empty;
str = streamReader.ReadToEnd();
Response.Write(str);
}

public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
return true;
}

这个是运行的异常
Server Error in '/' Application.
