Now there are three main ways to buy train tickets. One is the railway's own 12306 website, which is also the most commonly used way for young people. I sorted out why I can't get the tickets. I hope I can help you.
Why can't you grab tickets
In fact, whether online scalpers or various ticket grabbing software, they also buy tickets from 12306 platform, but they can quickly "grab" tickets for the following two reasons:
Good hardware! Independent servers, highly configured routes, seven types of 10 Gigabit network cables, 100 gigabit network, multi-threaded ticket grabbing, and multiple machines starting at the same time are not problems. They only brush out the one you dream of and earn your money for you.
On the basis of highly configured hardware, "software" is also indispensable.
First of all, let's take a look at the steps to go through when buying tickets online: login account, query date, select train number, select seat, add passengers, verify QR code, submit order (occupied seat) and pay order.
For normal users to buy tickets, in addition to following the above steps step by step, there are also restrictions on refresh time and number of tickets. 12306 in order to prevent scalpers from backbrushing, the following restrictions are set: the time for two ticket checks shall not be less than 5 seconds; You need to enter the verification code to log in and submit the order; You can only buy 5 tickets for one order.
Make an appointment in advance and there are no tickets in less than a second after the sale?
Now there are three main ways to buy train tickets. One is the railway's own 12306 website, which is also the most commonly used way for young people. However, as mentioned earlier, the transport capacity of the railway can not meet the needs of everyone. Moreover, the more populous the first tier cities are, the more difficult it is to grab tickets. In big cities such as Shenzhen and Shanghai, tickets are basically robbed as soon as they are released every day.
However, the train tickets of 12306 will not be released all at once. Generally, a small number of remaining tickets will be released at a time. After grabbing the tickets, some people cancel the order for various reasons, and these tickets will return to the ticket pool. There are too many people who will buy tickets in a moment.
Moreover, some longer routes sell tickets according to sections. There are more people getting on at large stations such as Wuhan, Zhengzhou and Nanchang. Trains passing through these cities will reserve some tickets for passengers getting on at these stations in advance. Therefore, some passengers get on at the starting station, but they can see that many carriages are vacant.
The second way to buy train tickets is all kinds of ticket grabbing software, which is also a popular way this year. Like high-speed rail housekeeper, flying pig, Ctrip, meituan and so on, they have launched their own ticket grabbing tools.
The principle of the ticket grabbing software is also very simple, that is, first obtain the authorization of the user's 12306 account, and then refresh the 12306 page every few seconds by using the script of the server. If the ticket is swiped out, the order will be placed automatically immediately. Because the order placing speed of the server script is certainly faster than that of manual operation, and the server can keep an eye on 12306 for 24 hours, it can place an order automatically once there is a spare ticket.
Therefore, in theory, the ticket grabbing software must be more efficient than manual grabbing. However, although ticket grabbing software is claimed to be free, it often provides paid "acceleration package". Now the charging method of ticket grabbing software is generally to set a ticket grabbing frequency. The higher the user pays, the higher the ticket grabbing frequency will be. When there are few remaining tickets, it is natural that users with high frequency of ticket grabbing are more likely to grab tickets.
