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 = " " ;

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" ;
    
    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" ,

  • 
• 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!
