Of course, this is only the most basic, to achieve the various front-end and back-end functions of the website, it will be much more complicated. Xiaocheng understood according to the knowledge he had learned before that the most popular and cutting-edge and convenient programming language in China is the Mangyu language, which was designed and developed by Liu Xian, the CEO of Manyou.com. In the year 2000, because of its security and convenience, the language had gradually replaced the most popular programs such as ASP, CGI or JSP at that time, and became the mainstream language of large websites.

Well, just learn this language! Search is also a product of the company, and you don't have to think about it to know that you must use the language to develop and design.

Many universities have special courses for the language, and if you want to get started, ordinary people only need to spend about a week, after all, it is enough to master the basic rules of the language, and then slowly learn in use, bit by bit. It's like even a three-year-old child can speak, but if you can write a splendid article, I'm afraid it will be difficult to do it without one or two decades of skill.

For a genius who can understand it at one point, a week is too long, and the embodiment of intelligence in learning is to bypass the class, many genius programmers, as long as they look at the basic rules of the language, they can roughly grasp it, the learning process is just an afternoon, and Wen Xiaocheng completed the process, it took four minutes and thirteen seconds.

Looking at a web page from a program's point of view is actually quite simple, and all web pages can be summed up in one sentence: displaying, entering, and managing data in "some form".

Xiaocheng just published a post, which is equivalent to adding a piece of data to the database, and the administrator deletes it, which is the same reason. As for the IP address blocking, it is actually a decision of the program: if the IP address of the visit is the same as the one in the database, the access is denied. Xiaocheng as an ordinary registered user,And the administrator is different in terms of permission,And this permission,In fact, it also comes from the judgment of the program,If you want to crack the website,The key lies in the judgment of the program,Just let the program mistakenly think that you are the administrator!

Next, Xiaocheng began to look for flaws in a targeted manner, and at the same time searched for various ways to deceive servers on the Internet. Tried and failed. It doesn't seem to work, after all, the sticker bar serves hundreds of millions of people every day, and the methods circulating on the Internet must have been prevented, Xiao Cheng simply closed his eyes, recalled all the source code of the login page and the related reference page in his mind, and deduced the process word by word.

When logging in, enter the username and password, and the system will compare the username and password with the database, and if they are consistent, the login will be successful. If the username is grouped as an administrator, the administrator privilege is granted. Translating the programming language to this is roughly what it means. The format is as follows: If "User Group = Administrator", then the administrator privilege is granted. The quotation marks are the criteria for determining whether you are an administrator.

Xiao Cheng smiled slightly, and found a loophole in this sentence.

When you register a new account called: "1>0 or", after logging in, the decision statement will change to "1>0 or username group = administrator", then give administrator permissions. 1 is necessarily greater than 0, so this ID directly becomes the administrator.

With the identity of the administrator,There are more things you can see.,It turned out that the deletion of his post was an ID called Xuan0988,0988 is the area code of Xiangyang City.,But who this ID is is still unclear.,Xiaocheng used management permissions,Restore your own post,And add red、Essence operation,And also did the regional solid top。 After that, all the locked accounts were released, and at the same time he set a small account as a moderator, and after doing all this, he was still not satisfied, so he simply changed the account password of Xuan 0988.

Grandma's, high IQ is so capricious!

On the other hand, Professor Dai has already made more than a dozen phone calls, either students or colleagues, and many of them are heavyweights in academia and education. In fact, Professor Dai himself is low-key, but he also has 20,000 or 30,000 fans, and the friends he is looking for are often hundreds of thousands, hundreds of thousands of fans, and at the same time they all reprinted the questioning article, the initial prototype of that article was written by Xiaocheng, that is, the article "Is it an Olympiad competition or a sports lottery? It is purely an online article, but it is inflammatory, and the emotions are expressed, but it is still a little empty, but after Professor Dai's polishing, it is much fuller, not only telling the true meaning of the problem, but also adding a lot of reflection and advice. The Mathematics Olympiad selects children who are talented in mathematics to be encouraged, which is a good thing, but if it is involved in the whole people, and it is linked to the high school entrance examination, it is contrary to the original intention.

Under this wave of public opinion offensive, even several large web portals have reprinted this blog post, and then the impact is even greater, and the Xiangyang Municipal Education Bureau was also forced to respond in the official Weibo: As the organizer, publicizing and organizing this competition is within the scope of our Education Bureau. Although the competition has attracted local students and their enthusiasm for participating is extremely high, the increase in the number of students will not affect the fairness of the competition.

Having said so much, it's the same as not saying it.

But it doesn't matter, the purpose of this wave of hype has been achieved, there are still many schools before they didn't expect to hit the big luck, after Xiaocheng's post broke out, the number of applicants is more, and now almost all school-age students in Xiangyang City have participated in the registration, so that the examination room prepared by the organizing committee is not enough, and the classrooms of the three universities in the city have been temporarily requisitioned, which is barely arranged.

..................

Shengyang City, Hushi Town, the headquarters of Busy Friends Group, Han Peng, the person in charge of the search, took a document and knocked on the door of the chairman's office. In the house, a young man of twenty-five or sixteen was talking to someone in front of a computer.

President of Busy Friends Group, Liu Busy.

Speaking of which, he has many other titles, such as President of Busy Friends Group, President Emeritus of Harvard University Huaxia Branch, Chief Consultant of Lu's Real Estate, and Executive Chairman of Huaxia Internet Association...... Blah blah blah, but now his character is a father.

"Son, it's not a big deal to read extracurricular books in class, and your dad and I haven't read it less, but you have to give the teacher a face, I told you about the "Property Law" or something, and there is nothing wrong with using it here, but you should pay attention to the occasion, it's not good if the teacher can't get off the stage, if you want to get things done, the best way is to seek consensus, not one party to overwhelm the other, do you know son?"

He had a headset with him, and he didn't know what the other party was saying.

"Yes, the right way is to give the teacher face in front of his classmates, where there is no one, let's reason with him again, it doesn't matter if you are unreasonable, we are smart people, smart people have a hundred ways to repair her!"

Liu Busy Diary: Iamback.

As for the hacking methods involved in the article, it is actually an injection vulnerability that has been rotten on the street, and basically no website would have made such a low-level mistake ten years ago, and it will not be as simple as it is written in the book. However, we are a novel, not a technical document, so try to write it in a straightforward way, and don't take it seriously if you know how to program. In addition, the so-called "Blank Search", "Vast Friends Network", "Vast Language" or something, including Liu Busy in Hushi Town, Shengyang City, knows what is going on after reading Lao Dao's first book "It's All Black Silk Causing Trouble". It doesn't matter if you haven't read it, it doesn't affect the plot of this book.
