c# - 使用 SSL 从 C# 应用程序调用 WebService

Question

在我的 C# 桌面应用程序中，我调用了用 php 开发的 Web 服务。我可以有 CA 文件。我不知道如何通过 SSL 调用 Web 服务并验证证书。我必须通过服务器传递什么以及期望从服务器响应什么以进行身份​​验证？老实说，我不知道。

编辑:引用自:http://weblogs.asp.net/jan/archive/2003/12/04/41154.aspx

//调用网络服务之前 System.Net.ServicePointManager.CertificatePolicy = new MyPolicy();

public class MyPolicy : ICertificatePolicy
{
    X509Certificate clientCert = null;

    public MyPolicy() {
        clientCert = X509Certificate.CreateFromSignedFile(HTTPUtility.CERT_FILE);
    }

    public bool CheckValidationResult(ServicePoint srvPoint, X509Certificate certificate, WebRequest request, int certificateProblem)
    {
        Console.WriteLine("********* Into CheckValidationResult : " + certificate.ToString());

        Console.WriteLine("####### Client Certificate : " + clientCert.ToString() + "\n" + "Subject = " + clientCert.Subject);
        Console.WriteLine("Issuer : " + clientCert.Issuer + "\n Seral No : " + clientCert.GetSerialNumberString());
        Console.WriteLine("Not Before : " + clientCert.GetEffectiveDateString() +" \n Not After : " + clientCert.GetExpirationDateString());
        Console.WriteLine("Thumb Print : " + clientCert.GetPublicKeyString());
        Console.WriteLine("######## EQuals SERVER CERT : " + clientCert.Equals(certificate));

        // Force to return true
        return true;
    }
}

以上检查方法是否正确？如果不是为什么以及解决方案是什么。我还收到此警告“'System.Net.ServicePointManager.CertificatePolicy' 已过时:'CertificatePolicy 对于此类型已过时，请改用 ServerCertificateValidationCallback。”。

有了这个我怎么知道 CheckValidationResult() 是否返回 false ？

非常感谢任何帮助。

谢谢

Answer 1

您是否尝试过使用过时消息中推荐的 ServerCertificateValidationCallback？例如，您可以将如下所示的方法添加到现有的 MyPolicy 类中:

public bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
    Console.WriteLine(sslPolicyErrors);  // Or whatever you want to do...
    return true;
}

完成后，您可以替换现有的

System.Net.ServicePointManager.CertificatePolicy = new MyPolicy();

符合以下条件:

MyPolicy policy = new MyPolicy();
System.Net.ServicePointManager.ServerCertificateValidationCallback = policy.ValidateServerCertificate;
