Free online crawler tool: free proxy crawler tool use

Hands-on teaching you to use free tools to catch proxy IPs

Crawler friends know that no proxy IP is like riding a bicycle on the highway - minutes to be stopped. Those free proxy tools on the Internet look quite fragrant, the actual operation of the pit is really quite a lot. Today we will teach you how to use ready-made tools to catch the proxy IP, and incidentally Amway a reliable proxy service provider.

Why do free agents always flop?

Anyone who has used a free agent understands that there are three major pain points that you can't get around:Short survival time(It may be cold in half an hour),Speed like a turtle.(It's a pain in the ass to load an image),Safety in doubt(The data may be intercepted). Especially for data collection, using a free agent is often disconnected in the middle of the collection.

 Let's take a test code for a free proxy
import requests

proxy = {"http": "123.45.67.89:8080"}
try: response = requests.get("", proxies=proxy, timeout)
    response = requests.get("http://example.com", proxies=proxy, timeout=5)
    print("Connection successful!")
except: response = requests.get("", proxies=proxy, timeout=5)
    print("Failed again...")

The wild card of building your own proxy pool

Here to teach you to use open source tools to get a temporary solution (long-term use or recommended professional services):

1. Installing Python'sfake-useragentlibrary anti-climbing
2. expense or outlayBeautifulSoupGrill Free Agent Website
3. Write a timed script to automatically verify availability

However, this method has a fatal injury - the maintenance cost is too high. Previously, there is a friend doing e-commerce, with this method for three days, the result of the proxy pool IP survival rate is less than 15%.

The right way to open a reliable service provider

This is the time to recommendipipgoIt's not an advertisement. I've tested their dynamic residential IPs, and I've been able to run a social media crawler for 12 hours without being blocked. There are three main things I like about them:

 Examples of API calls for ipipgo
import requests

api_url = "https://api.ipipgo.com/getproxy"
params = {
    "key": "Your API key",
    "protocol": "socks5",
    "count": 10
}

response = requests.get(api_url, params=params)
proxy_list = response.json()['data']
print(f "Fresh IP pool: {proxy_list}")

Guidelines on demining of common problems

Q: Can't I just make do with the free agent?
A: It's okay to play small, don't risk it for serious projects. Last time someone used a free IP to crawl data, and the account was blocked for three months.

Q: How do I choose the right package?
A: personal use choose standard dynamic, enterprise-level business directly on the enterprise version. Need to choose a fixed IP static, cross-border business remember to find customer service to private line program

Q: Is API extraction complicated?
A: They have ready-made code templates in the background, support Python/Java/PHP three languages, copy and paste can be used!

Finally, a lesson in tears: do not buy cheap IP services of small workshops! Before the cheap to buy a unknown service provider, the results of the IP are blacklisted, do e-commerce price comparison directly by the platform black. Now use ipipgo mainly focus on their carrier resources, more than 200 countries of the local IP is not blowing, do overseas business when the advantage is obvious.

If you can't decide, ask for a test kit to try the waters first. Their customer service can give a customized plan, which is much better than buying without a clue. Remember, a good proxy IP should be"Silent."The presence of the - you can't feel it when you're using it, but you'll be blind without it in minutes.
