Tips for using a crawler agent (how to do a crawler agent)

Guys, today I'm going to share with you my experience is about crawling agent use skills (crawling agent how to do) yo, this is a very interesting topic, a little like we played hide and seek as a child, hehehe, I think we are also very interested in this topic.

Tips for Using Crawler Agents

Imagine you are a bird and you want to observe the scenery around you, but you don't want to be discovered, then you need to find a tree hole where you can hide your identity, right? Yeah, actually, crawlers use proxies that are kind of like this tree hole. You can let their own crawler hidden in the proxy IP "tree hole", so it is not easy to be found by the target site.

First of all, we have to find some proxy IPs, which is like finding some "tree holes" to hide in. Some proxy IPs are free, just like the wild fruits on the roadside, which may not be very sweet, but can always fill your stomach; while some proxy IPs need to be paid, just like the fruits in the carefully cultivated orchard, which are guaranteed to be of good quality. However, whether it is free or paid proxy IP, we have to keep trying to use, after all, sometimes free of charge may not be not sweet.

Then, we also have to pay attention to change the proxy IP in time, just like changing the hole in the tree, otherwise the target site found, it will not be worth it. Ah, this is like when we were children playing hide-and-seek, other people found us hiding place, we have to change the place in time to hide, otherwise it will be easy to be caught.

Lastly, don't forget to set up proper request headers and pretend that you are a normal browser visit so that the target website doesn't recognize us. It's like we are dressing up, putting on the right clothes and sunglasses to pretend to be a normal person.

How to be a reptile agent

Below, I'll give you an introduction to the specifics of what to do in order to make our crawler use the proxy? Nah, let me write a sample code for your reference:

"`ipipgothon
import requests
from fake_useragent import UserAgent

# Get a random user agent
headers = {
'User-Agent': UserAgent().random
}

# Setting Proxy IP
proxy = {
'http': 'http://127.0.0.1:8888',
'https': 'https://127.0.0.1:8888'
}

# Initiate request with proxy
response = requests.get('target url', headers=headers, proxies=proxy)
“`

Hey, this code is like a crawler for us to change the "invisibility cloak", so that it can not be detected in the case of quietly crawling the target site data. However, partners should remember that the use of proxy IP is also required to comply with relevant laws and regulations Oh, do not do illegal things ah.

Well, today's share is here, I hope that the partners have a more in-depth understanding of the use of crawler agents. Remember to try and practice more, in order to master this "hide and seek" skills yo. Go, go, go!
