使用C＃登录https站点
我正在尝试编写一个登录Verizon网站的小程序，然后检查该月剩余的分钟数。 我需要帮助找出如何使用C＃登录网站。 我知道我需要使用webrequest发布登录信息，但我不知道如何去做。 登录表单的网站是https://login.verizonwireless.com/amserver/UI/Login ，但我不确定我要发布到网站登录的信息以及如何操作。 以下是我发现的网站来源。 如果有人可以帮我弄清楚如何从C＃程序登录，我将非常感激。 感谢您的任何帮助。
form method =“post”autocomplete =“off”action =“https://login.verizonwireless.com:443/amserver/UI/Login”name =“loginForm”id =“loginForm”onsubmit =“return disableBut（）; “>
input type =“hidden”name =“realm”value =“vzw”/>
input type =“hidden”name =“goto”value =“”/>
input type =“hidden”name =“gotoOnFail”value =“”/>
input type =“hidden”name =“gx_charset”value =“UTF-8”/>
input type =“hidden”name =“rememberUserNameCheckBoxExists”value =“Y”/>

首先，你错过了两个重要的领域:)如果你看一下HTML，表单中有两个额外的字段IDToken1 （用户名）和IDToken2 （密码）。
如果您将这些提供给POST请求，您应该返回一些cookie，然后您可以在后续请求中使用这些cookie。 这些将标识您为登录用户。
当然，我无法完全测试这个，因为我没有有效的登录，但这是一个开始：
class VerizonLogin { CookieContainer Cookies = new CookieContainer(); void Main() { Login("test","testpass"); // Now the cookies in "Cookies" are all set. // Ensure you set CookieContainer on all subsequent requests } void Login(string username, string password) { var wr = (HttpWebRequest)WebRequest.Create("https://login.verizonwireless.com:443/amserver/UI/Login"); wr.Method = "POST"; wr.ContentType = "application/x-www-form-urlencoded"; wr.Referer = "https://login.verizonwireless.com/amserver/UI/Login"; // my tests show this is needed wr.CookieContainer = Cookies; var parameters = new Dictionary{ {"realm", "vzw"}, {"goto",""}, {"gotoOnFail",""}, {"gx_charset", "UTF-8"}, {"rememberUserNameCheckBoxExists","Y"}, {"IDToken1", username}, {"IDToken2", password} }; using (var requestStream = wr.GetRequestStream()) using (var writer = new StreamWriter(requestStream,Encoding.UTF8)) writer.Write(ParamsToFormEncoded(parameters)); using (var response = (HttpWebResponse)wr.GetResponse()) { // here you need to detect a correct login... this might be one of the cookies. // if incorrect throw an exception or something. } } string ParamsToFormEncoded(Dictionary parameters) { return string.Join("&", parameters.Select(kvp => Uri.EscapeDataString(kvp.Key).Replace("%20","+") + "=" + Uri.EscapeDataString(kvp.Value).Replace("%20","+") ).ToArray()); } }
以下是您需要执行此操作的两个function。 是的，你是对的，你必须使用webrequest，但是你需要伪装一个回调来validation来自https的证书。 您应该可以在框中使用这些。
C＃
private bool ValidateCert(object sender, System.Security.Cryptography.X509Certificates.X509Certificate certificate, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors) { return true; } private string PostToSite(string url) { string result = string.empty; byte[] postBuffer = System.Text.Encoding.GetEncoding(1252).GetBytes("realm=vzw&goto=&gotoOnFail=&gx_charset=UTF-8&rememberUserNameCheckBoxExists=Y"); HttpWebRequest webRequest = (HttpWebRequest)Net.WebRequest.Create(_endpoint); webRequest.KeepAlive = false; webRequest.AllowAutoRedirect = false; ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(ValidateCert); webRequest.ContentLength = postBuffer.Length; webRequest.Method = "POST"; webRequest.ContentType = "application/x-www-form-urlencoded"; using (Stream str = webRequest.GetRequestStream()) { str.Write(postBuffer, 0, postBuffer.Length); } using (System.Net.HttpWebResponse res = (HttpWebResponse)webRequest.GetResponse()) { using (StreamReader sr = new StreamReader(res.GetResponseStream())) { result = sr.ReadToEnd(); } } return result; }
VB.NET
