如何使用asp.net c＃以编程方式登录安全的https网站 [英] How to login Secured https website using asp.net c# programatically

问题描述

您好，

任何人都可以帮助我，登录到一个网站（编程），这是https。我有该网站的用户名和密码。我正在使用HttpWebRequest和HttpWebResponse ..



我的代码如下： -



CookieContainer cookies =新的CookieContainer（）;

WebRequest loginRequest;

//转到登录页面以便我们获得一个cookie

loginRequest =（HttpWebRequest）HttpWebRequest.Create（https：// sitename）;

loginRequest.Headers.Add（Authorization，Basic+ Convert.ToBase64String（ASCIIEncoding.ASCII.GetBytes（+ TextBox1.Text +：+ TextBox2.Text +）））;

loginRequest.UseDefaultCredentials = true;

loginRequest.UserAgent =Mozilla / 4.0（兼容; MSIE 7.0; Windows NT 6.0）;

loginRequest .CookieContainer = cookies;

loginRequest.AllowAutoRedirect = false;



HttpWebResponse loginResponse =（HttpWebResponse）loginRequest.GetResponse（）;



//现在我们有了cookie，我们可以正确登录

HttpWebRequest doLogin =（HttpWebRequest）HttpWebRequest.Create（https：// siteName）;



//doLogin.UseDefaultCredentials = true;

doLogin.UserA gent =Mozilla / 4.0（兼容; MSIE 7.0; Windows NT 6.0）;

doLogin.Method =POST;

doLogin.ContentType =text / html; charset = UTF-8;

doLogin.AllowAutoRedirect = false;



使用（StreamWriter sw = new StreamWriter（doLogin.GetRequestStream（）））

{

sw.Write（usr =< username>& pass =+ TextBox2.Text +& mc = 1& guid =& dbnum = 0& ic = 1& task = dologin& app = library& x = 32& y = 10）;



}



doLogin .CookieContainer = cookies;

doLogin.Referer =https://secure.sbigeneral.in/Extranet/faces/premiumcalc_landingpage;



HttpWebResponse Response =（HttpWebResponse）doLogin.GetResponse（）;



string resphead = Response.Headers [Set-Cookie];



string resp = Response.StatusCode.ToString（）;



使用（StreamReader） sr = new StreamReader（Response.GetResponseStream（）））

{

string textresponse = sr.ReadToEnd（）;



}

Hello,
can anyone help me out, in login to a website(programatically) that is https. I have the username and password of that site. I am using HttpWebRequest and HttpWebResponse..

my code is as follow:-

CookieContainer cookies = new CookieContainer();
WebRequest loginRequest;
//Go to login page so that we get a cookie
loginRequest = (HttpWebRequest)HttpWebRequest.Create("https://sitename");
loginRequest.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes("" + TextBox1.Text + ":" + TextBox2.Text + "")));
loginRequest.UseDefaultCredentials = true;
loginRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)";
loginRequest.CookieContainer = cookies;
loginRequest.AllowAutoRedirect = false;

HttpWebResponse loginResponse = (HttpWebResponse)loginRequest.GetResponse();

//Now that we have the cookie we can do a proper login
HttpWebRequest doLogin = (HttpWebRequest)HttpWebRequest.Create("https://siteName");

//doLogin.UseDefaultCredentials = true;
doLogin.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)";
doLogin.Method = "POST";
doLogin.ContentType = "text/html;charset=UTF-8";
doLogin.AllowAutoRedirect = false;

using (StreamWriter sw = new StreamWriter(doLogin.GetRequestStream()))
{
sw.Write("usr=<username>&pass=" +TextBox2.Text + "&mc=1&guid=&dbnum=0&ic=1&task=dologin&app=library&x=32&y=10");

}

doLogin.CookieContainer = cookies;
doLogin.Referer = "https://secure.sbigeneral.in/Extranet/faces/premiumcalc_landingpage";

HttpWebResponse Response = (HttpWebResponse)doLogin.GetResponse();

string resphead = Response.Headers["Set-Cookie"];

string resp = Response.StatusCode.ToString();

using (StreamReader sr = new StreamReader(Response.GetResponseStream()))
{
string textresponse = sr.ReadToEnd();

}
