Hello, everyone. The meeting will answer your questions. 12306 second light, 12306 why there are no tickets in 1 second, many people do not know, now let's take a look at it!

Answer:

1, for tight tickets, demand exceeds supply, many people will wait for tickets to be sold out, and some people will use ticketing software, which will cause this situation if there are more tickets. 12306 is one of the most frequently visited websites by reptiles in China. The crawlers of travel software and ticket grabbing software want to scan the data hundreds of thousands of times per second in order to show the result of too many tickets.

2. Introduction:

3. There are hundreds of ticketing software on the market, which also dealt a fatal blow to 12306 servers; 12306 official online in the first year of online ticketing in 2010; in 2011, some programmers spontaneously launched browser ticketing plug-ins and provided them to users free of charge. In 2012, Internet companies began to develop professional ticketing software, and the ticket plug-in of Cheetah browser also dragged down 12306. Ticketing software is based on crawlers and can be written in python. Use the code to simulate the browser, request the 12306 server, analyze the return results, and submit the ticket purchase order; even the scissors hand can request up to 2 times a second. If you exceed 1230 points, your hands will become sore. The machine does not turn sour and can request 10 or more requests per second; according to statistics, on January 4, 2019, the number of requests reached 13.6 billion; fortunately, a lot of ticketing software was blocked a few days before 12306, so you don't have to worry about being ripped off by ticketing software. To tell you the truth, ticketing software is a fast spelling machine. When invoicing, submit the order. But there are too many ticketing software, and more and more users are queuing up. After spending 50 yuan on an acceleration package, they still couldn't get a ticket at the end of the line. Moreover, ticketing software is a black box. Who knows to spend 50 yuan did not give the queue, may not place an order at all, but also have been fooling around to share acceleration packages, asking friends and relatives to help speed up, not only make users sick.

This is the end of this article. I hope it will be helpful to all of you.
