Train ticket grabbing tool

Online reservations for train tickets have been launched, but very few people can book them. The reason is that the system of the Ministry of Railways is not powerful enough. There is a limit on the number of people who can log in, and the service is often busy and always times out. The page is also an iframe, so if something goes wrong you have to start from the beginning. It was time-consuming and labor-intensive, so I wrote this tool. Since I only fetch HTML and ignore Shenma JS and Shenma CSS, the speed is definitely much faster than the website of the Ministry of Railways, and if I make a mistake in a step, I will try again. Just one step is enough, there is no need to start over, and the chances of booking tickets should be much higher than on the website.
This tool was originally written two days ago, but it was not released at that time. First, there were still problems with some judgments, and second, I was afraid that this tool would fall into the hands of scalpers, making it more difficult for everyone to book tickets. Therefore, in the past two days, I have added an authorization function at home, which limits the number of daily reserved tickets. In addition, a violent mode has been added, which greatly increases the chance of booking tickets, but may be banned by the Ministry of Railways, so the use of violent mode is not allowed under ordinary authorization.
There is still a small problem with this tool, that is, the login cookie cannot be shared with IE. As a result, after the final successful booking and payment, I have to log in again. The reason why I haven't been able to find it is Shenma. However, this does not have much impact. After the ticket is successfully booked, you have 45 minutes to pay. As long as you complete the payment within 45 minutes, the ticket is still yours. If you cannot log in for 45 minutes, or the payment is unsuccessful, I suggest you still I'll wash my face first and try again; this also has the advantage that I can turn off my program when paying, so that no one will worry about me recording their bank card and other information.

Authorization code:
1EE94894-9092-453F-82FB-045CEC13EBEB
This authorization code limits the number of daily reservations and allows a maximum of two successful reservations (note: unsuccessful payment or cancellation after successful reservation is also counted)
