Scholar’s Advanced Technological System

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

Lu Zhou explained: "Accurately, it is the ticket app, I am going to buy a server to try, you have any good suggestions -"

"Don't be tossed," Wang Xiaodong unsatisfactorily interrupted Lu Zhou's words and said, "Will you take a server? Do you have a place to put it? You can try it in the bedroom, it won't run for half a minute, the whole floor is accompanied. You pull the brakes together."

Uh? !

Is there such an exaggeration?

But listening to his tone, I always feel what he tried...

Across the phone, Wang Xiaodong continued to say indifferently: "If you want to make some pocket money, you can pick up some outsourcing projects. There is no need to work hard to run the APP. If you have free money to play, you can try to rent a cloud server. You can save money by dumping the server yourself. The electricity fee, the noise of the network, and the heat dissipation do not require you to worry about it. There are charges according to the flow, and there are also hours or monthly subscriptions."

"Can it still be like this?" Lu Zhou squatted.

"So I said that the layman is so busy," Wang Xiaodong sighed and patiently continued. "And, the app you developed is best to register a domain name. I don't think you have considered it."

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

“No,” Wang Xiaodong replied decisively. “For example, if you developed an app on the ios system, if you write a fixed server IP address in the code, once the cloud service operator replaces the server device, you not only need to repackage and upload the Appstore, but also It may be cut directly to more than half of the users. After all, not everyone will open the automatic update."

Holding the grass? !

Good insurance, Lu Zhou really did not hear this.

After a pause, Wang Xiaodong continued: "And the most important thing is that your crawler program needs to collect data from a third-party website, and may be blocked by the website operator. This problem can be avoided with a cloud server. After all, like Ali The level of operators, the IP pool is an astronomical number, and it also saves you the trouble of engaging in virtual IP."

Once I talked about the field that I was good at, the accident of the schoolmaster became a slogan, and it was said to be an endless stream. This made Lu Zhou think of the bright comrades in their bedroom. Once he talked about the play of the enchantress, he could speak for half an hour.

Of course, these things that Wang Xueba said are still quite valuable.

Lu Zhou not only listened very carefully, but also took a small notebook and remembered.

"...If it is from the 12306 website, the crawler itself can't consume too much server resources, especially now that it is in the promotion stage for small and medium-sized enterprises, and there is a big price discount. I think... you can rent a package at the beginning. A million PPS server will do, more than 300 pieces a month is enough. When the user traffic goes up, you can directly upgrade the service, which is more convenient than tossing the server yourself."

Holding the grass, learning to do is not a schoolmaster.

Lu Zhou felt that he had such a phone call and saved at least tens of thousands of dollars.

Of course, my server still has to buy, but it can be delayed for a while, waiting for his money to turn around.

"Thank you, please ask for dinner the next day." Lu Zhou solemnly thanked.

"More."

The topic changed from computer to eating. Wang Xiaodong’s enthusiasm for speaking suddenly returned to zero, and he returned to the state of cherishing the word like gold.

However, just as Lu Zhou was ready to ask questions, he did not bother to continue to chat. After saying thank you again, he hung up.

Holding the mouse, Lu Zhou landed on the Alibaba Cloud page and began searching for services.

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

"A million pps server monthly rent as long as 300 yuan, including 100G free ssd cloud disk, plus two hundred yuan can be upgraded 1TB ... excess part per G data 0.3 yuan / month charge. CPU and intranet bandwidth and packet transmission and receiving capacity All can upgrade their services independently, 50% discount within three years..."

This price can be said to be quite favorable. If there is no accident, he can control the expenses of the operating APP within a thousand yuan in the short term. If the user breaks through the expected amount, he only needs to pay for the upgrade service.

"That's it, the next step is to promote the app, and it is necessary to catch up before the start of the school season." Lu Zhou thought.

Go post and advertise, promote in the new group...

In short, the primary goal is to make the flow user volume!

Filled in the application for renting the server, Lu Zhou went to the bathroom to take a shower, dried his hair and returned to the bedroom.

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

Looking back, I saw Liu Rui, who was lying on the side, spitting a sneak peek.

Lying in the trough!

Is this kid not sleeping well? Why did you spit it up?

Lu Zhou did not have time to hesitate. He immediately jumped off the ladder and took Liu Rui to the toilet.

"Go away... I can still drink." Liu Rui stumbled out and said, reaching out and pushing his own boat.

When I saw this reaction, Lu Zhou suddenly panicked and quickly said, "I am fucking, Rui Ge, you have to hold me back! I warn you, I just took a shower!"

"vomit……!"

Lu Zhou: "..."

This bath was washed in white, and I felt that I couldn't sleep. The stomach in the bedroom was sour, it was sour and sour.

Lu Zhou vowed that this was his last time, drinking with Liu Rui.

In the end, Liu Rui vomited and awake, and looked at the clothes of the land and the clothes of Lu Zhou, and said a few times, sorry.

Turn off the air conditioner, and the two people cleaned up the debris together and opened the front and rear doors to ventilate.

After finishing this, Lu Zhou took a shower again. After he came out, he said that he was holding his mat and decisively slipped into the squad's bedroom and went to the ground.

This ghost weather, no air conditioning can't sleep.

......

The next day, Lu Zhou got a bed.

When returning to the bedroom, Liu Rui was still fighting in bed.

Lu Zhou did not take care of him, went straight to his position and opened the computer.

The cloud server that was applied for was quickly put in place. After uploading the data, the web crawler started working, and the data of the 12306 official website, the station ticket information and other information were climbed down and sorted and summarized. Anyone can save the local account password and use it online. Achieve one-click ticket purchase, sale reminder, automatic ticket purchase, regular brush ticket and so on.

This has some features, and it is quite convenient. Although the light blue interface is monotonous, it is at least not annoying.

Now that my mobile phone got up and down, Lu Zhou randomly selected a station to test it again, and found that the normal order was completely OK, and finally canceled the order at the payment ring node.

Then he spent another whole day, he followed the process to put the app on the Android market, Baidu mobile assistant, 360 assistant and other domestic large Android software download platform.

Through the developer backstage, looking at the number of downloads that were stable at 0, Lu Zhou sighed.

"Sure enough, the operation app is not so good, the wine is not fragrant, and the alley is deep. No user is a big problem."

"The free promotion of several platform applications does not know when it will come down."

Shaking his head, Lu Zhou turned off his laptop and stuffed the book he was looking at today into his bag.

"No matter what, try to operate for about half a year, it is really a matter of accumulating experience."
