AliCloud Proxy IP Pool: AliCloud Proxy IP Pool Access

What exactly is the purpose of the AliCloud proxy IP pool?

Engaged in the old iron of the web crawler know that many sites will block the IP address. This time you need a proxy IP pool toAutomatic switching between different IP addressesIt is like changing the "clothes" for the crawler program, so that the target site can not be recognized. Although AliCloud does not directly sell proxy IP services, but allows users to build their own IP pool.

Here's a pitfall to be aware of: many tutorials teach you to maintain your own IP pool, and as a result, the maintenance cost is more expensive than buying a ready-made one. For example, the cost of renting a server, verifying IP availability and all this crap, and in the end, it is better to find a professional service provider. This is the time to reflect theipipgoThe advantage of their dynamic IP pool is directly connected to the AliCloud, eliminating the need for intermediary folding.

Three minutes to fix AliCloud docking

The point is, how to use ipipgo's proxy IP in the AliCloud environment?It's really just four steps:

import requests

 Here is the address of the API provided by ipipgo
proxy_api = "https://api.ipipgo.com/getproxy"

 Get the latest proxy IP
def get_proxy():
    resp = requests.get(proxy_api)
    return f "http://{resp.text}"

 Example of use
proxies = {
    "http": get_proxy(),
    "https": get_proxy()
}
response = requests.get("Your destination URL", proxies=proxies)

Notice in this code that theprofound theory (in Daoism and Buddhism): Re-acquire IPs for each request to avoid repeated use of bans. ipipgo's IP pool is automatically updated every 5 minutes, much faster than 30 minutes for many providers.

Why choose ipipgo over others?

A comparison table for you will make it clear:

Special mention of theirIntelligent RoutingFunction: It can automatically match the nearest proxy node according to the target website server location. For example, if you want to visit a website in Hangzhou, the IP pool will automatically assign IPs exported from Hangzhou's server room, which directly doubles the speed.

Guide to avoiding the pit

Finally, a couple of common potholes that newbies step into:

1. Don't write a dead IP address in the code, always use a dynamic way to get it
2. HTTP and HTTPS proxies should be configured separately, many sites now force https
3. Remember to set the timeout retry mechanism, recommended 3 retries + 2 seconds timeout

If you're too lazy to do this, you can just ask ipipgo support for the SDK, which is a Python package that encapsulates these exceptions and is much less time consuming than writing them yourself. There was also a new user recentlyFree 3-day trialThe event is recommended to experience it first.
