Analysis of difficulties in website Logon of the Ministry of Railways

• Microsoft IE browser is required
  • The Ministry of Railways website only supports Internet payment
• Websites use HTTPS protocol
  • The client does not allow cross-origin access.

Technical Analysis

• Use the Microsoft IE developer toolbar to crack the automated Logon Process

Start step

• To use IE8 and later versions, you need to download the official ie developer Toolbar of Microsoft for IE7 and later versions. The download link is as follows:
  • Internet Explorer developer toolbar: http://www.microsoft.com/download/en/details.aspx? Id = 18359
• In the IE Address Bar visit the Ministry of Railways login page https://dynamic.12306.cn/otsweb/loginAction.do? Method = init
• You only need to enter your username, password, and verification code once.
• Press the F12 shortcut key to bring up the IE developer toolbar> script tab> copy the code to the content text box> click Run script.

  • 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.content+doc ument. getelementbyid ('username'); var Password = _ifrmain.contentdomaindoc ument. getelementbyid ('Password'); var randcode = _ifrmain.contentdomaindoc ument. getelementbyid ('randcode'); var sublink = _ifrmain.contentdomaindoc ument. getelementbyid ('sublink'); var submiturl = u RL; $. 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 ('Enter the correct Verification Code ')>-1) {alert (' enter the correct verification code! ') ;}; If (MSG. indexof ('Too many users currently access')>-1) {relogin (MSG);} else {location. replace (queryurl) ;}}, error: function (MSG) {relogin (MSG) ;}, beforesend: function (xhr ){;}});} vaR COUNT = 1; function relogin (MSG) {count ++; sublink. innerhtml = "(" + Count + ") logon... "+ MSG; setTimeout (submitform, 500);} submitform ();
• Subsequent execution
  • After you click the run script button, the login operation is automated for the customer. You only need to wait until the login is successful.
• If your user name is displayed, the logon is successful.

Conclusion

• Insufficient
  • The ticket purchase peak has passed the previous day. This technique is too late. Someone else ordered my ticket. I didn't pay too much attention to using technology to achieve easy login.
• Foot
  • The return ticket peak is coming soon!
