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

/article/5386003.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!
