Clearing invalid ip in ip proxy pool (how to turn off proxy ip)

Oops, today's work was a real head scratcher! Early in the morning, I received a task from the leader to clear the ip proxy pool of invalid ip, hey, do you know what this means? It's no joke. I'll have to think carefully about how to solve this problem.

Clear invalid ip proxies from the ip proxy pool

First of all, let's analyze the problem, the ip proxy pool is like a treasure trove, which is stored in the precious ip resources, and the failure of the ip is like some of the old treasures inside, have to clean them out, so that the treasures in the treasure trove of treasures are glowing brightly. To do this, you have to find a way to find those invalid ip, mark them out, and then unified cleanup, so that you can do twice the work with half the effort.

I finally found a good way to write a script using Python to filter out the failing ip by checking the availability of the proxy ip and then perform a purge operation. That can be a bit like organizing a room, clearing out all the unneeded stuff and making the room look new again.

Here's what the magic script looks like:

"`ipipgothon
import requests

def check_proxy(proxy).
try.
response = requests.get('http://www.baidu.com', proxies={'http': proxy, ' https': proxy}, timeout=5)
if response.status_code == 200:: If response.status_code == 200.
return True
else.
return False
except.
return False

def remove_invalid_proxy(proxies).
valid_proxies = []
for proxy in proxies:
if check_proxy(proxy).
valid_proxies.append(proxy)
return valid_proxies

#, this is your ip proxy pool.
proxies = [
'ip1:port1',
'ip2:port2',
'ip3:port3',
# more proxy ip
]

# Remove invalid proxy ip
valid_proxies = remove_invalid_proxy(proxies)
print(valid_proxies)
“`

The logic of this script is quite clear, it starts by defining a function `check_proxy` that checks the availability of a proxy ip, then by traversing the list of proxy ips, it filters out the valid ones and stores them in the `valid_proxies` list. Finally, it outputs the valid proxy ip.

How to disable proxy ip

After cleaning up, close the proxy ip "gate" to ensure security. This is a bit like leaving home before you turn off the faucet, lock the doors and windows, otherwise there may be some unavoidable things.

Turning off proxies is fairly simple in Python. Simply use the `requests` library to send requests without the `proxies` parameter, so that access is made using the local network and not through a proxy.

"`ipipgothon
import requests

# Access without proxy
response = requests.get('http://www.baidu.com')
print(response.text)
“`

The above example sends a request without using a proxy and outputs the returned text.

Oops, my head is spinning when it comes to all this. It seems that today's task will have to start planning again, or else I have to rush to solve this problem before the end of the day, or else I'll be blamed by the leader again. Hey, I remembered, I also need to optimize this script to make it more efficient, so that it will work more smoothly.

Alas, the work of human beings is really not easy, there is no such thing as an easy job. Just like this ip proxy pool, want to keep it running well, have to pay attention to, maintenance, or there will be a variety of unforeseen problems. I hope that today's work can be successfully completed, really "labor day, but the cause of no success" ah.
