谁给个HttpWebRequest或者webclient获取https网页内容的代码！

[liying520]

如题。。求一个用上面类获取https网页内容的代码。只是确定功能无需导入证书等功能

[呵呵呵呵呵呵呵呵呵呵呵呵]

public bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{   
    //直接确认，否则打不开   
    return true;
}
    
private void button1_Click(object sender, EventArgs e)
{
    ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(CheckValidationResult);
    HttpWebRequest req = (HttpWebRequest)WebRequest.CreateDefault(new Uri("https://zu14.cn/"));
    req.Method = "GET";
    HttpWebResponse res = (HttpWebResponse)req.GetResponse();
    //正常使用了，和访问普通的 http:// 地址一样了
}

楼上别直接抄袭CSDN上的啊。给个具体确实能用的例子。。包含调用的类

[baimerde]

补充一个问题，如果要先登录系统，如何抓取登陆后的网页信息
期待例子……

要先登录的就用WebRequest模拟post方法,用myHttpWebRequest.CookieContainer.GetCookieHeader(myHttpWebRequest.RequestUri)得到对方set的cookie,然后带着这个cookie去访问需要登录才能访问的页面

这个方法，你可以直接调用！

/// <summary>
/// 获得页面的html代码
/// </summary>
/// <param name="url">页面地址</param>
protected string getHtml(string url)
{
    string html = "";
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Accept = "*/*";
    HttpWebResponse response = null;
    Stream stream = null;
    StreamReader reader = null;
    try
    {
        response = (HttpWebResponse)request.GetResponse();
        stream = response.GetResponseStream();
        reader = new StreamReader(stream, Encoding.UTF8);
        html = reader.ReadToEnd();
    }
    catch (Exception excpt)
    {
    }
    finally
    {
        if (reader != null)
        {
            reader.Close();
            reader.Dispose();
        }
        if (stream != null)
        {
            stream.Close();
            stream.Dispose();
        }
        if (response != null)
        {
            response.Close();
        }
    }
    return html;
}

sr.Close();
