使用System.Net.WebClient与HTTPS证书 [英] Using System.Net.WebClient with HTTPS certificate

问题描述

在我的C＃Windows客户端，我有一个POST提交母舰。我想固定当然，在提交的数据，所以我支付HostGator的发给我一个SSL证书。

In my C# Windows client, I have a POST submission to "the mothership". I want the data in the submits to be secured, of course, so I paid for HostGator to issue me an SSL certificate.

我救离.CER文件，我建设的要求这样：

I saved off the .CER file, and I'm constructing the request as such:

//wrapper for WebClient object to use certificate file
class SecureWebClient : WebClient
{
    protected override WebRequest GetWebRequest(Uri address)
    {
        HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(address);
        string certPath = @"e:\mycertificate.cer";
        X509Certificate myCert = X509Certificate.CreateFromCertFile(certPath);
        request.ClientCertificates.Add(myCert);
        return request;
    }
}

//request
private static SecureWebClient client = new SecureWebClient();
private static NameValueCollection = new NameValueCollection();
nvc.Add(POST_ACTION, ACTION_CODE_LOGIN);
nvc.Add(POST_EMAIL, email);
nvc.Add(POST_PASSWORD, password);

sResponse = System.Text.Encoding.ASCII.GetString(client.UploadValues(BASE_URL + ACTION_PAGE, nvc));

它抛出一个System.Net.WebException：

Its throwing a System.Net.WebException:

基础连接已关闭：上一个发送发生意外的错误

The underlying connection was closed: An unexpected error occurred on a send.

的InnerException是一个System.IO.IOException：

The InnerException is a System.IO.IOException:

由于没有意外的数据包格式，握手

The handshake failed due to an unexpected packet format.

这是什么我做错了任何见解？

Any insight on what I am doing wrong?

推荐答案

如果你不可以使用的客户的证书和您可以访问使用你的服务器的 https：//开头，然后你的代码应该是这样的：

If you're not using client certificates and you can access your server using https:// then your code should look like:

private static WebClient client = new WebClient();
private static NameValueCollection nvc= new NameValueCollection();

nvc.Add(POST_ACTION, ACTION_CODE_LOGIN);
nvc.Add(POST_EMAIL, email);
nvc.Add(POST_PASSWORD, password);

sResponse = System.Text.Encoding.ASCII.GetString(client.UploadValues(BASE_URL + ACTION_PAGE, nvc));

只要您的 BASE_URL 使用的https：// < /强>，那么所有的数据（向和从服务器）将被加密。

As long as your BASE_URL uses https:// then all the data (to and from the server) will be encrypted.

IOW使用SSL / TLS从客户机到服务器，不需要在客户端做任何特殊（含证书），除了使用的 https：//开头作为方案，因为操作系统提供的一切（如可信任的根），你需要确保数据传输。

IOW using SSL/TLS from a client to a server does not require the client to do anything special (with the certificate), besides using https:// as the scheme, since the operating system provides everything (e.g. trusted roots) you need to secure the data transmission.
