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

Lu Zhou explained: "To be precise, it's a ticket-grabbing APP, I'm going to buy a server to try, do you have any good suggestions-"

"Don't toss," Wang Xiaodong unceremoniously interrupted Lu Zhou's words and said, "Will you take the server?" Do you have a place to put it? You put it in the bedroom and try it, it won't run for half a minute, and the whole floor will accompany you to pull the gate. ”

Belch?!

Is it so exaggerated?

But listening to his tone, it always feels like he's tried......

Over the phone, Wang Xiaodong continued with an indifferent face: "If you want to earn some pocket money, you can take on some outsourcing projects, and there is no need to work thanklessly to operate the APP." If you have spare money and want to have fun, you can try renting a cloud server, which will definitely save you money than flipping the server yourself. You don't need to worry about electricity, internet bills, noise and heat dissipation, there are charges by flow, and there are also hourly or monthly subscriptions. ”

"Can it still be like this?" Lu Zhou was stunned.

"So what's the fun for the layman," Wang Xiaodong sighed and continued patiently, "Also, it's better to register a domain name for the app you developed, and I guess you haven't thought about it." ”

"Isn't it okay to 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 equipment, you not only need to repackage and upload the Appstore, but also may be directly cut off more than half of the users, after all, not everyone will turn on automatic updates." ”

Hold the grass?!

It's so dangerous, Lu Zhou really hasn't heard of this.

After a pause, Wang Xiaodong continued: "And the most important thing is that your crawler wants to collect data from third-party websites, and the website operator may block the IP, and this problem can be avoided by using a cloud server." After all, for an operator of the level of Alibaba, the IP pool is astronomical, which also saves you the trouble of engaging in virtual IP. ”

Once he talked about the field he was good at, this scholar unexpectedly turned into a chatter, and it was called a chatter. This reminded Lu Zhou of Comrade Guangming in their bedroom, once he talked about the game of the Enchantress, he could talk for half an hour.

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

Lu Zhou not only listened attentively, but also took a small notebook to memorize.

“…… 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, the price is very discounted. I want to think about it...... In the initial stage, you can rent a server with a capacity of 1 million PPS, and more than 300 yuan a month is enough. When the number of user visits goes up, you can directly spend money to upgrade the service, which is definitely more convenient than tossing the server yourself. ”

Holding the grass, the scholar deserves to be a scholar.

Lu Zhou felt that he had saved at least tens of thousands of yuan in unjust money with such a phone call.

Of course, he still has to buy his own server, but he can delay it for a while and wait for his funds to turn over.

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

"Say it again."

The topic changed from the computer to eating, and Wang Xiaodong's enthusiasm for speaking instantly zeroed, and he returned to the state of cherishing words like gold.

However, it happened that Lu Zhou was about to finish asking all the questions, and he didn't have the heart to continue the awkward chat, so after saying thank you again, he hung up the phone.

Holding the mouse, Lu Zhou landed on the Alibaba Cloud page and began to search for service items.

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

"The monthly rent of a million pps server is only 300 yuan, including 100G free ssd cloud disk, and 200 yuan can be upgraded to 1TB...... The excess part will be charged at 0.3 yuan/month per G of data. The CPU, intranet bandwidth and packet sending and receiving capacity can be upgraded independently, and the service can be discounted by 5% within three years......"

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

"So be it, the next thing is to promote the app, and we have to rush before the beginning of the school season." Lu Zhou pondered.

Go to the post bar to advertise and promote it in the freshman group......

In short, the primary goal is to increase the number of streaming users!

After filling out the application for renting a server, Lu Zhou went to the bathroom to take a shower, dried his hair and returned to the dormitory.

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

When I looked back, I saw Liu Rui, who was lying on his side, vomiting.

it!

Didn't this kid sleep well just now? Why did you throw up?

Lu Zhou didn't have time to hesitate, he immediately jumped down from the ladder and dragged Liu Rui to the toilet.

"Go away...... I can still drink it. Liu Rui came out in a daze, and reached out to push his own land boat.

Seeing this kid's reaction, Lu Zhou immediately panicked, and hurriedly said, "Fuck, Brother Rui, you have to hold back for me!" I warn you, I just took a shower! ”

"Vomit ......!"

Lu Zhou: "......"

This bath is washed in vain, and I can't sleep, and there is a sour stomach smell in the bedroom, which is simply sour.

Lu Zhou swore that this was the last time he would drink with Liu Rui.

In the end, Liu Rui came to his senses after spitting and spitting, looked at the mess all over the ground and Lu Zhou's clothes, and said sorry several times in embarrassment.

Turning off the air conditioner, the two of them cleaned up the wreckage together, and opened the front and rear doors for ventilation.

After doing this, Lu Zhou took a new bath, and after coming out, without saying a word, he hugged his mat and resolutely slipped to the squad leader's bedroom to lay on the floor.

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

……

The next day, Lu Zhou got up early.

When he returned to the dormitory, Liu Rui was still snoring in bed.

Lu Zhou didn't pay attention to him, went straight back to his place and turned on the computer.

The cloud server of the application was quickly in place, and after the data was uploaded, the web crawler began to work, crawling down and sorting out the data such as the remaining ticket information of the station on the 12306 official website, and anyone can use the account and password saved in the local area to realize one-click ticket purchase on the Internet, sales reminders, automatic ticket purchases, regular ticket swiping and so on.

There are all the functions that should be there.,And it's quite convenient.,Although the light blue interface is a bit monotonous.,But at least it's not annoying.。

Now that his mobile phone is up, Lu Zhou casually chose a station to test it again, and found that it was completely OK to place an order normally, and finally clicked to cancel the order in the payment link.

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

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

"Sure enough, the operation of the app is not so easy to do, and the wine is not fragrant, I am afraid of deep alleys, and it is a big problem to have no users."

"I don't know when I can come down for the free promotion that several platforms have applied for."

Shaking his head, Lu Zhou turned off his laptop and stuffed the books he was going to read today into his school bag.

"No matter, try to operate for about half a year first, it's really not right to accumulate experience."
