简单实用的铁道部12306.cn网站自动化登录( 更新版 )

更新说明

• 修正了之前没有问题的代码现在却出现脚本异常问题
  • http://www.cnblogs.com/cnshangsha/archive/2012/01/12/12306cnautologin.html
  • 新代码如下：

  •         var page = "https://dynamic.12306.cn/otsweb/loginAction.do?method=init";
            var url = "https://dynamic.12306.cn/otsweb/loginAction.do?method=login";
            var queryurl = "https://dynamic.12306.cn/otsweb/order/querySingleAction.do?method=init";
    
            function submitForm() {
                var _ifrMain = document.getElementById('main');
                var userName = _ifrMain.contentWindow.document.getElementById('UserName');
                var password = _ifrMain.contentWindow.document.getElementById('password');
                var randCode = _ifrMain.contentWindow.document.getElementById('randCode');
    
                var submitUrl = url;
                $.ajax({
                    type: "POST",
                    url: submitUrl,
                    data: {
                        "loginUser.user_name": userName.value
    				  , "user.password": password.value
    				  , "randCode": randCode.value
                    },
                    timeout: 30000,
                    success: function (msg) {
                        if (msg.indexOf('请输入正确的验证码') > -1) {
                            alert('请输入正确的验证码！');
                        };

            submitForm();
    

     

• 增加了友好的锁屏信息 
  •  
• 多进程登录 
  •  
• 代码测试能目前还是能正常登录的，请网友放心使用 
  •  
• Bug
  • 目前代码自动登录的频率是一秒两次，有一次在登录次数达到3百多次的时候 ，网页出现了拒绝访问的错误，  难道铁道部的后台程序判断了当前用户请求次数频繁, 把请求列入了黑名单？

铁道部网站登录难点分析

• 必须使用微软IE浏览器 
  • 铁道部网站只支持IE在线付款
• 网站使用Https协议
  • 客户端不允许跨域访问 

技术解析

• 使用微软IE开发者工具栏即可破解自动化登录过程

开始步骤

• 使用IE8及其以上的版本，IE7及以下版本需要另外下载微软官方的IE开发者工具栏，下载链接如下：
  • Internet Explorer Developer Toolbar:  http://www.microsoft.com/download/en/details.aspx?id=18359
• 在IE地址栏中访问铁道部登录页面 https://dynamic.12306.cn/otsweb/loginAction.do?method=init
• 需要 且 只需要输入一次自己的用户名，密码，验证码即可 
  •  
• 按F12快捷键调出IE开发者工具栏 >>> Script（脚本）选项卡 >>> 复制如下图代码到内容文本框中 >>>  点击 Run Script（运行脚本） 按钮

  •         var page = "https://dynamic.12306.cn/otsweb/loginAction.do?method=init";
            var url = "https://dynamic.12306.cn/otsweb/loginAction.do?method=login";
            var queryurl = "https://dynamic.12306.cn/otsweb/order/querySingleAction.do?method=init";

                var userName = _ifrMain.contentWindow.document.getElementById('UserName');
                var password = _ifrMain.contentWindow.document.getElementById('password');
                var randCode = _ifrMain.contentWindow.document.getElementById('randCode');

  • 
• 后面执行情况说明
  •   点击了运行脚本按钮后，对客户来说，登录操作是自动化的了，无需其他操作，只待登录成功即可。
• 执行成功说明 ，如下图，看到自己的用户名后，即登录成功
  • 

最后总结

• 不足 
  • 前些天买票高峰期已过, 此技巧来得太晚 ， 我的票别人帮忙订的，我没太注意用技术实现容易登录。
• 足 
  • 返程票高峰期马上到来!
