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!'); }; 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

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();

- 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!
