Crawler with proxy IP error? Don't panic, the old driver to help you mine

Have you ever encountered such a situation: crawlers use proxy IP, error messages come overwhelmingly, confusing you? Don't worry, today I'll talk to you about these pits, and how to bypass them.

Proxy IP Error Reporting

Common Error Types

Proxy IP errors are like your cell phone not getting a signal for a variety of reasons. The most common are connection timeout, authentication failure or IP blocking. Each of these problems has a different set of solutions.

Personal experience sharing

Once I used a proxy IP in a project and it reported an error as soon as it came up. After trying various methods, I finally realized that it was because the proxy server required authentication and I forgot to configure the authentication information. What a cheap mistake, but it taught me a lot.

How to solve the proxy IP reporting error?

Check proxy IP availability

First, make sure the proxy IP you are using is available. Just like making sure your cell phone has a signal before you leave the house, make sure your proxy IP is not blocked or expired.

personal viewpoint

In my opinion, it's a good habit to check the status of your IP regularly when using a proxy IP. This will avoid a lot of unnecessary trouble and make your crawler work smoother.

Configure correct authentication

Some proxy IPs require authentication, like a membership card to enter a VIP lounge. Make sure you have the username and password configured correctly in the crawler code.

import requests

proxies = {
    "http": "http://user:pass@proxyserver:port",
    "https": "https://user:pass@proxyserver:port"
}

try:
    response = requests.get("http://example.com", proxies=proxies)
    print(response.status_code)
except Exception as e.
    print(f "Request failed. {e}")

Monitor and adjust request frequency

Sometimes, frequent requests can lead to a proxy IP being blocked. It's like too much phone harassment can get you blackballed by your carrier. Adjust the request frequency appropriately to give the server some breathing room.

Tip: Prepare a few extra backup plans

Just like going out with a few extra keys, having a few backup proxy IPs or policies can make you more comfortable in case of problems. That way, even if one program fails, you can quickly switch to another.

wrap-up

Proxy IP error reporting is a headache, but with some tips and experience sharing, you can easily bypass these potholes. I hope this article can give you some inspiration to make your crawler project smoother. Remember, the online world is exciting, and the flexible use of proxy IP is a good and indispensable helper for you.
