Question

我正在创建一个C＃/ .NET应用程序来自动重新连接到wifi热点。 Internet访问检测工作正常，但我无法重新连接。 wifi热点使用HTTPS POST登录表单。

我尝试了stackoverflow的几个建议，但到目前为止没有任何工作：我从我的请求得到的答案是登录页面，我没有连接到互联网。

我试过了：

public class Hotspot
{
    public string Url { get; set; }
    public string Method { get; set; }
    public string Inputs { get; set; }

    public HttpStatusCode Connect()
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(this.Url);
        request.KeepAlive = false;
        request.ProtocolVersion = HttpVersion.Version10;
        request.Method = this.Method;

        ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(delegate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; });

        byte[] post_bytes = Encoding.ASCII.GetBytes(this.Inputs);
        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = post_bytes.Length;
        using (Stream requestStream = request.GetRequestStream())
        {
            requestStream.Write(post_bytes, 0, post_bytes.Length);
        }

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        Console.WriteLine(new StreamReader(response.GetResponseStream()).ReadToEnd());
        Console.WriteLine(response.StatusCode);
        return response.StatusCode;
    }

    public void Connect2()
    {
        using (WebClient client = new WebClient())
        {
            client.Headers.Add(HttpRequestHeader.ContentType, "text/xml");
            System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
            byte[] response = client.UploadData(this.Url, "POST", encoding.GetBytes(this.Inputs));
            Console.WriteLine(encoding.GetString(response));
        }
    }
}

this.Url看起来像@“https://hotspot.somtehing.com/nb4_crypt.php”
this.Method是“POST”
this.Inputs是一个字符串，表示所有输入及其值（例如@“username = me＆amp; password = something＆amp; conditions = on＆amp; blablah =”）

两种方法都输出登录页面，但我仍未连接到Internet。第一种方法（Connect）返回200。我检查了输入值，它们是正确的：我可以使用网络浏览器进行连接。
