The first quarter of each year , yes Python The climax of part-time order taking , Nearly period of time , The demand for reptile and digital classification services in various industries has increased exponentially . Friends in the circle are not idle on weekends , Take advantage of the peak season to make a lot of money .
therefore , Recently, the technical realization was consulted in the background of official account 、 There are more and more friends who take orders part-time .
In the last ten days, I have received more than 600 messages about part-time jobs , I find that some problems occur very frequently , After summarizing everyone's confusion , In general, it can be divided into three situations ：
1、0 I want to do Python Part-time job , I don't know how to start learning
2、 No private work , No price negotiation , No experience, worry about stepping on the pit
3、 Little practical experience , Not familiar with mainstream technology , Worried about the project
The first order was introduced by a friend , Just learning at that time Python, Climb data for a company , Made more than a thousand . Since then, I've become proficient , Often receive some data processing orders during holidays , Most of the time, part-time income is the income of the main business 2~3**** times .
Python A part-time job with a lot of money , Mostly reptilian . Mainly crawling websites 、 A small program or APP The data of , Analyze and process the data , Or provide crawler programs and technical support directly to customers .** What technology does it take to receive an order ？** Reptiles , As Python Ace Technology , It is a necessary magic skill for taking orders part-time . The program principle is very simple , It's easy to learn .
Ordinary web crawlers usually have only four steps ： Target information website 、 Page grabbing 、 Page analysis 、 data storage . After understanding the principles and steps , It's easy to crawl data from ordinary websites .
Of course , That doesn't mean that's enough , Truly valuable resources , Often in large sites with perfect anti crawler measures . At this time , It needs to be used Python The key technology of reptiles —— Website anti crawler strategy and its countermeasures . I'm not sure about the anti crawler measures set up by the website , You can't climb to valuable resources , Even less high-value orders . Common anti reptile measures ：
The target detected that it was blocked by a reptile IP
The target returned encrypted data
The target returned dirty data , Unrecognizable
The target website must be logged in to access
Javascript Dynamic rendering , The crawler cannot read
The target website has a verification code and cannot be accessed
ajax Asynchronous transmission , Crawler grabs empty information
Picture camouflage and confusion +CSS The offset +SVG mapping
Go back to the three major issues listed at the beginning , For want to use Python Open up a sideline to make money , But not familiar with reptile and anti reptile Technology , There is no way to receive orders , Friends who also lack part-time experience .
I suggest you start studying now Python, Many friends will worry about these problems ：
Here I want to say , Instead of thinking about these, there are some things , Why don't you just get started , Learned again , I can't learn these problems , Only after learning, can I know ？
That's how I came here , Let's learn first , When you encounter a problem, you are solving it , It's better than daydreaming here . One step at a time , Make steady progress in a down-to-earth manner . I don't believe in learning . If you are Ready to learn Python Or learning , You should be able to use the following ：
