简单实用的铁道部12306.cn网站自动化登录( 更新版 )

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！');

            };

            if (msg.indexOf('当前访问用户过多') > -1) {

                reLogin('回调结果:当前访问用户过多');

            }

            else {

                location.replace(queryurl);

            };

        },

        error: function (msg) {

            reLogin('回调结果:错误');

        },

        beforeSend: function (XHR) {

           ;

        }

    });

}

 

var count = 1;

function reLogin(msg) {

    count++;

    skm_LockScreen("(" + count + ")次登录中..." + msg);

    setTimeout(submitForm, 500);

}

 

function skm_LockScreen(str) {

    scroll(0, 0);

    var back = document.getElementById('skm_LockBackground');

    var pane = document.getElementById('skm_LockPane');

    var text = document.getElementById('skm_LockPaneText');

 

    var LockBackgroundCssString = "position: absolute;top: 0px;left: 0px;visibility: visible;display: block;width: 105%;height: 105%;background-color: #666;z-index: 999;filter: alpha(opacity=75);opacity:0.75;padding-top: 20%;";

 

    var LockPaneCssString = "z-index: 1000;position: absolute;top: 0px;left: 0px;padding-top: 25%;visibility: visible;display: block;text-align: center;width: 100%;";

 

    var textCssString = "width: 55%;background-color: #969;color: White;font-size: large;border: dotted 1px White;padding: 9px;margin-left: auto;margin-right: auto;";

      

    if (back)

        back.style.cssText = LockBackgroundCssString; 

    if (pane)

        pane.style.cssText = LockPaneCssString; 

    if (text) {

        text.innerHTML = str;

        text.style.cssText = textCssString; 

    }

}

 

var loginoutElement = document.getElementById('login_out');

loginoutElement.innerHTML = "<div id='skm_LockBackground' style='display: none;visibility: hidden;position: absolute;top: -100px;left: -100px;'></div><div id='skm_LockPane' style='display: none;visibility: hidden;position: absolute;top: -100px;left: -100px;'><div id='skm_LockPaneText'> </div></div>"; 

 

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

    submitForm();

     

  • 
• 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!
