Scholar’s Advanced Technological System

"You wrote a reptile in Python?" After listening to Lu Zhou's statement, Wang Xiaodong holding the phone frowned.

Lu Zhou explained: "Accurately, it is a ticket grabbing app. I am going to buy a server to try. What are your good suggestions?"

"Don't toss," Wang Xiaodong interrupted Lu Zhou politely. "Will you take a server? Do you have a place to put it? Try it in the bedroom, it won't run for half a minute, and it will accompany the whole floor. You pull the brakes together. "

Uh? !!

Is there such an exaggeration?

I can't help but listen to his tone, always feel like he tried ...

Wang Xiaodong continued indifferently over the phone: "If you want to make some pocket money, you can take out some outsourcing projects. There is no need to work hard to please the APP. If you have spare money and want to play, you can try to rent a cloud server. You can save money by using your own server. You do n’t need to worry about electricity, network, noise, and heat dissipation. You can charge by traffic, or by the hour or monthly. "

"Can this be the case?" Lu Zhou stunned.

所以 "So the layman is busy," Wang Xiaodong sighed, and continued patiently. "Also, the app you develop is best to register a domain name, I guess you haven't considered it."

"Can't I just use the server IP directly?" Lu Zhou asked.

"No," Wang Xiaodong replied decisively, "For example, if you develop an app on the ios system, if you write a fixed server IP address in the code, once the cloud service operator changes the server device, you not only need to repackage and upload the Appstore, but also May be cut off more than half of users, after all, not everyone will turn on automatic updates. "

Hold grass? !!

It's dangerous, Lu Zhou has never heard of this.

After a pause, Wang Xiaodong continued, "And the most important thing is that your crawler needs to collect data from third-party websites, which may be blocked by the website operator. Using a cloud server can avoid this problem. After all, it is like Ali Operators of all levels, the IP pool is an astronomical figure, which saves you the trouble of virtual IP. "

Once you talked about your area of ​​expertise, this Xue Ba unexpectedly turned into a 唠, and it was a torrent of talk. This made Lu Zhou think of Comrade Guangming in their bedroom. Once he talked about the play of Yao Ji, he could talk for half an hour.

Of course, these things Wang Xueba talks about are still quite valuable.

Lu Zhou not only listened attentively, but also took a small book in hand.

"... If it is from the 12306 website, the crawler itself cannot consume too much server resources, especially now it is in the promotion stage for small and medium-sized enterprises, and the price is very favorable. I think about it ... In the early days, you could rent a sending and receiving package. A million PPS server will do. More than three hundred a month will suffice. When the user visits up, you can directly spend money to upgrade the service, which is definitely more convenient than tossing the server yourself. "

Holding the grass, Xueba is indeed Xueba.

Lu Zhou feels that he has saved at least tens of thousands of dollars in unjust money on such a phone call.

Of course, you still have to buy your own server, but you can postpone it for a while until his funds turn over.

"Thank you, I'll invite you to dinner another day." Lu Zhou thanked him solemnly.

"Again."

The topic changed from computer to eating. The enthusiasm of Wang Xiaodong's open speech instantly returned to zero and returned to the state of cherishing words as gold.

But I just finished all the questions that Lu Zhou was about to ask, and I didn't want to continue talking awkwardly. After saying thank you again, I hung up the phone.

Holding the mouse, Lu Zhou landed on the Alibaba Cloud page and started searching for service items.

Indeed, as Wang Xiaodong said, Alibaba Cloud is currently doing promotion, and the server has considerable discounts.

"A monthly rent of one million pps server is only 300 yuan, including 100G free ssd cloud disk, plus two hundred yuan can be upgraded by 1TB ... The excess is charged at 0.3 yuan per G data per month. CPU and intranet bandwidth and packet sending and receiving capabilities They can upgrade their services independently, with a 50% discount within three years ... "

This price can be said to be quite favorable. If there is no accident, he can control the expenditure of operating the APP within 1,000 yuan in the short term. If users exceed the expected number, they only need to pay to upgrade the service.

"That's it. The next issue is to promote the app. It must be before the start of the school season." Lu Zhou thought.

Post it and advertise it in the freshmen group ...

In short, the primary goal is to get streaming users up!

The completed application for renting a server, Lu Zhou took a bath in the bathroom, dried his hair, and returned to the bedroom.

However, just as he was about to climb up the ladder to sleep, he suddenly smelled a pungent stench.

I looked back and saw that Liu Rui lying on the side spit out.

Look down!

Is this kid not sleeping well just now? Why did you vomit?

Lu Zhou had no time to hesitate, immediately jumped off the ladder, dragged Liu Rui to the toilet.

走 "Go away ... I can still drink." Liu Rui stumbled out, reaching out to push his own land boat.

Seeing this boy ’s reaction, Lu Zhou panicked immediately, and said quickly: "I fuck, Rui brother, you have to hold me back! I warn you, I just took a bath!"

"Spit ...!"

Lu Luzhou: "..."

The bath was washed in white and I couldn't sleep. The sour stomach in the bedroom was sour.

Lu Lu swears that this is his last time to drink with the boy Liu Rui.

At last, Liu Rui vomited and woke up, looking at the mess in the ground and Lu Zhou's clothes, and said embarrassingly several times.

I turned off the air conditioner, and the two men cleaned up the debris together, and opened the front and rear doors to ventilate.

After doing this ~ www.readwn.com ~ Lu Zhou took a new bath. After coming out, he said nothing, holding his mat, and decisively slipped into the monitor's bedroom and laid the floor.

In this ghost weather, I can't sleep without air conditioning.

Uh ...

The next day, Lu Zhou got up early.

When I returned to the bedroom, Liu Rui was still snoring in bed.

Lu Zhou didn't bother him, he went back to his place and turned on the computer.

The application cloud server was in place quickly. After uploading the data, the web crawler began to work, crawling and collating the data of the station train tickets and other information on the 12306 official website, and anyone can save it on the Internet through the account password Realize one-click ticket purchase, sales reminder, automatic ticket purchase, regular ticket swipe and so on.

It should have all the functions, and it is quite convenient. Although the light blue interface is a bit monotonous, at least it will not be annoying.

Now my mobile phone got on and off, Lu Zhou randomly chose a station and tested it again. It was found that the normal order was completely OK. Finally, he chose to cancel the order in the payment ring node.

Then he spent another whole day, and according to the process, he listed the app on the Android market, Baidu mobile assistant, 360 assistant and several other large Android software download platforms in China.

Through the developer's background, watching the steady download volume of 0, Lu Zhou sighed.

"Sure enough, running an app is not so easy to do. You are afraid of the alleys if the wine is not fragrant. No users is a big problem."

"I do n’t know when it will be available for free promotion on several platforms."

I shook my head, Lu Zhou shut down the laptop, and stuffed the book to be read into the schoolbag.

"No matter, try to operate for about half a year first, it is really right to accumulate experience."
