这篇文章是有关模拟登录网站方面的。
实现步骤；
我们以登录人人网为例，首先需要分析人人网登录时POST的数据格式，这个可以通过IE9中只带的F12快捷键，调出开发人员工具。如下图：
通过开始捕获得到POST的地址和POST的数据
POST数据：
POST地址：
http://www.renren.com/PLogin.do
下面就是代码示例来得到登录后页面（http://guide.renren.com/guide）的数据
HTMLHelper类
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net; using System.IO; using System.Threading; namespace Test { public class HTMLHelper { /// <summary> /// 获取CooKie /// </summary> /// <param name="loginUrl"></param> /// <param name="postdata"></param> /// <param name="header"></param> /// <returns></returns> public static CookieContainer GetCooKie(string loginUrl, string postdata, HttpHeader header) { HttpWebRequest request = null; HttpWebResponse response = null; try { CookieContainer cc = new CookieContainer(); request = (HttpWebRequest)WebRequest.Create(loginUrl); request.Method = header.method; request.ContentType = header.contentType; byte[] postdatabyte = Encoding.UTF8.GetBytes(postdata); request.ContentLength = postdatabyte.Length; request.AllowAutoRedirect = false; request.CookieContainer = cc; request.KeepAlive = true;
//提交请求 Stream stream; stream = request.GetRequestStream(); stream.Write(postdatabyte, 0, postdatabyte.Length); stream.Close();
//接收响应 response = (HttpWebResponse)request.GetResponse(); response.Cookies = request.CookieContainer.GetCookies(request.RequestUri); CookieCollection cook = response.Cookies; //Cookie字符串格式 string strcrook = request.CookieContainer.GetCookieHeader(request.RequestUri); return cc; } catch (Exception ex) { throw ex; } } /// <summary> /// 获取html /// </summary> /// <param name="getUrl"></param> /// <param name="cookieContainer"></param> /// <param name="header"></param> /// <returns></returns> public static string GetHtml(string getUrl, CookieContainer cookieContainer,HttpHeader header) { Thread.Sleep(1000); HttpWebRequest httpWebRequest = null; HttpWebResponse httpWebResponse = null; try { httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(getUrl); httpWebRequest.CookieContainer = cookieContainer; httpWebRequest.ContentType = header.contentType; httpWebRequest.ServicePoint.ConnectionLimit = header.maxTry; httpWebRequest.Referer = getUrl; httpWebRequest.Accept = header.accept; httpWebRequest.UserAgent = header.userAgent; httpWebRequest.Method = "GET"; httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); Stream responseStream = httpWebResponse.GetResponseStream(); StreamReader streamReader = new StreamReader(responseStream, Encoding.UTF8); string html = streamReader.ReadToEnd(); streamReader.Close(); responseStream.Close(); httpWebRequest.Abort(); httpWebResponse.Close(); return html; } catch (Exception e) { if (httpWebRequest != null) httpWebRequest.Abort(); if (httpWebResponse != null) httpWebResponse.Close(); return string.Empty; } } }
public class HttpHeader { public string contentType { get; set; } public string accept { get; set; } public string userAgent { get; set; } public string method{get;set;} public int maxTry { get; set; } } }
测试用例：
通过程序登录了网站后而直接进入登录后的页面。
首先还是发起一个启用一个web会话，然后发送模拟数据请求，获取会话的CooKie，再根据该CooKie将其写入到本地，通过程序直接打开登录后的页面。
该功能可用于无法修改第三方系统源代码而要做系统单点登录。
我们先在HTMLHelper类中添加一个方法：
/// <summary> /// 获取CookieCollection /// </summary> /// <param name="loginUrl"></param> /// <param name="postdata"></param> /// <param name="header"></param> /// <returns></returns> public static CookieCollection GetCookieCollection(string loginUrl, string postdata, HttpHeader header) { HttpWebRequest request = null; HttpWebResponse response = null; try { CookieContainer cc = new CookieContainer(); request = (HttpWebRequest)WebRequest.Create(loginUrl); request.Method = header.method; request.ContentType = header.contentType; byte[] postdatabyte = Encoding.UTF8.GetBytes(postdata); request.ContentLength = postdatabyte.Length; request.AllowAutoRedirect = false; request.CookieContainer = cc; request.KeepAlive = true;
//提交请求 Stream stream; stream = request.GetRequestStream(); stream.Write(postdatabyte, 0, postdatabyte.Length); stream.Close();
//接收响应 response = (HttpWebResponse)request.GetResponse(); response.Cookies = request.CookieContainer.GetCookies(request.RequestUri); CookieCollection cook = response.Cookies; //Cookie字符串格式 string strcrook = request.CookieContainer.GetCookieHeader(request.RequestUri); return cook; } catch (Exception ex) { throw ex; } }
再根据获取的CookieCollection写入本地，并打开登录后的页面
[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)] public bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData) { HttpHeader header = new HttpHeader(); header.accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/x-silverlight, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, application/x-silverlight-2-b1, */*"; header.contentType = "application/x-www-form-urlencoded"; header.method = "POST"; header.userAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)"; header.maxTry = 300; CookieCollection mycookie = HTMLHelper.GetCookieCollection("http://www.renren.com/PLogin.do", "email=aaa%40163.com&password=111&icode=&origURL=http%3A%2F%2Fwww.renren.com%2Fhome&domain=renren.com&key_id=1&_rtk=90484476", header); foreach (Cookie cookie in mycookie) //将cookie设置为浏览的cookie { InternetSetCookie("http://" + cookie.Domain.ToString(), cookie.Name.ToString(), cookie.Value.ToString() + ";expires=Sun,22-Feb-2099 00:00:00 GMT"); } System.Diagnostics.Process.Start("http://guide.renren.com/guide"); }
这样即可直接通过程序打开登录后的页面：
