Teach you step by step how to do keyword matching projects (search engines)----The seventh day, teach you how to do----

The seventh day

Xiao Shuai Shuai took it back and studied it carefully all night.

I found out that the code was actually written by myself, and there were a few more classes. Boss Yu had not copied my code, and he despised Boss Yu in his heart.

In fact, everyone has a common problem. Those who write procedures will always despise writing object-oriented, because they do not understand what object-oriented is, and it will take several years for them to write it well.

When Xiao Shuaishuai learned programming, he clearly knew that there was a concept of function and how to write a function, but in fact, even if there were hundreds of lines of code in a function, he didn’t know how to come up with multiple functions in advance, just to make an appointment. : Look how awesome I am, with hundreds of lines of code.

Although Xiao Shuaishuai despises Boss Yu in his heart, he feels very refreshed when he sees Boss Yu’s code, everything is so natural.

But he still couldn’t help but ask Boss Yu:

"Boss Yu, actually your code is the same as mine. Why do you write it like this? What are the benefits of writing it like this?"

Boss Yu said: "Well, yes, the codes are basically the same, and sometimes there are some more codes. Did you find out during the comparison process that the code I wrote is correct? Your code is summarized and categorized."

Object-oriented is actually the summary and classification of process-oriented.

It’s a pity that Xiao Shuaishuai still doesn’t understand it well. Although he is not very happy in his heart, after all, he is the boss, so he is right to listen to his words.

Xiao Shuaishuai replied: "Well, yes, then I can extend it by inheriting Source."

Boss Yu returned: "Well, yes, the inherited Source only needs to assign values ​​to the attribute keywords inside. Isn't it very convenient? If you are not familiar with object-oriented, I suggest you learn these basics first. ".

Object-oriented: Object Oriented (OO) is a software development method. Object-oriented concepts and applications have transcended programming and software development and expanded to fields such as database systems, interactive interfaces, application structures, application platforms, distributed systems, network management structures, CAD technology, artificial intelligence and other fields. [From Baidu entry]

"Object-oriented" specifically refers to the use of design methods such as encapsulation, inheritance, and polymorphism in programming.

Boss Yu continued: "You can continue to expand one according to my method to deepen your thinking. Just the "Are you looking for it?" task."

Xiao Shuai Shuai replied: "Okay".

Xiao Shuai Shuai completed the task in less than an hour.

Xiao Shuai Shuai showed the code to Boss Yu and was praised by Boss Yu, which made him feel happy. However, Xiao Shuaishuai still does not understand the true meaning of object-oriented.

Shortly after Xiao Shuai Shuai was happy, he was troubled again. The reason was how to use Taobao API and how to get baby information? Where does the information come from?

Little Shuaishuai had no choice but to run to the boss again and ask for advice on how to defeat the enemy.

Boss Yu first asked him to read the Taobao API tutorial and gave him a URL: http://open.taobao.com for Xiao Shuaishuai to read by himself.

Xiao Shuai Shuai had to silently despise Boss Yu in his heart again. He asked me to go and see him. Why do you want me to see him? As soon as this strange thought came to him, Xiao Shuai Shuai quickly shook his head, trying to keep his mind clear. Keep thinking about it.

Just like that, Xiao Shuaishuai went to Taobao open platform to learn from it, and all the object-oriented things were forgotten. (0 Without actual training and understanding, I still follow the boss’s ideas 0)

PS: (Learning is a personal matter, and the project director only leads the door. Whether you can succeed or not depends on the individual. In fact, many people have this idea just like Xiao Shuaishuai, and some people will question someone’s ability. )

Wangdao SEO optimization software works on search engine optimization. My personal understanding of search engine optimization is that SEO creates and uses keyword optimization to help small and medium-sized enterprises’ websites rank higher in search engine query results to obtain the most effective user clicks. . It is based on the retrieval characteristics of search engines for web pages, so that the basic elements of website construction are suitable for the retrieval principles of search engines, so that the search engines can include as many web pages as possible and rank high in the natural retrieval results of search engines, ultimately reaching the website Promotional purposes. The main work of Wangdao search engine optimization is to optimize web content by understanding how various search engines crawl Internet pages, how to index them, and how to determine their ranking of search results for a specific keyword. , a technology that makes it in line with users' browsing habits, improves search engine rankings without damaging user experience, thereby increasing website visits, and ultimately improving the website's sales or publicity capabilities. The so-called "search engine optimization for Wangdao" is to make the website more easily accepted by search engines.
