Question

我正在尝试创建一个Windows应用程序，以便在网站关闭时发送警报，我首先编写这个基本表单以检查它是否正常工作。

HttpWebRequest httpReq = (HttpWebRequest)WebRequest.Create(textBox1.Text);
httpReq.AllowAutoRedirect = false;

HttpWebResponse httpRes = (HttpWebResponse)httpReq.GetResponse();

if (httpRes.StatusCode == HttpStatusCode.Found)
{
    MessageBox.Show("It works.");
}
else
{
    MessageBox.Show("Not able to ping");
}
httpRes.Close();

它工作正常，但当我想为SSL网站（https）做同样的事情时，它没有用，我查了一下并添加了

ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);

但仍然无法从https网站得到任何回复，我尝试了很多网站，所以我不认为它的网站问题，我是一个新手.net任何帮助表示赞赏。

我发现问题的人，https用200响应（OK）而http正在响应302（找到）所以我只是修改了我的条件为它添加200它就像一个魅力。对于任何对工作代码感兴趣的人，这里是

      public bool AcceptAllCertifications(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certification, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
    {
        return true;
    }
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);
        HttpWebRequest httpReq = (HttpWebRequest)WebRequest.Create(textBox1.Text);
        httpReq.AllowAutoRedirect = false;


            HttpWebResponse httpRes = (HttpWebResponse)httpReq.GetResponse();

            if (httpRes.StatusCode == HttpStatusCode.OK || httpRes.StatusCode==HttpStatusCode.Found)
            {
                MessageBox.Show("It works.");
            }
            else
            {
                MessageBox.Show("Not able to ping");
            }
            httpRes.Close();
       }
