Python Proxy IP POST Submit: Python Proxy POST Submit Data

Why do I need a proxy for data submission?

Have done the old iron crawler understand, directly with their own IP POST request is like running naked. For example, you want to submit a form to a website, even submit a dozen times, the server immediately give you a seal. At this time, if you change a few proxy IP turns to send, just like playing hide-and-seek, the server simply can not catch you.

Here's the point:Choosing a proxy IP depends on the business scenarioFor example, if you want to simulate real-life operations, you need to use a residential IP. For example, if you want to simulate the operation of a real person, you need to use a residential IP; if you are engaged in big data collection, data center IP is more cost-effective. We recommend ipipgo home three packages, static residential IP is suitable for the need to fix the authentication of the scene, dynamic for regular data submission.

Four Steps to Python Hands-on

First, go to the ipipgo website and get an API key, their extraction method is thief simple. Take the dynamic residential package for example, use this code snippet to get fresh IPs:

import requests

api_url = "https://api.ipipgo.com/getip?type=dynamic&apikey=你的密钥"
resp = requests.get(api_url).json()
proxy = {
    'http': f'http://{resp["ip"]}:{resp["port"]}',
    'https': f'http://{resp["ip"]}:{resp["port"]}'
}

Focus on three points:

1. Don't be lazy with timeout settingsRecommended 3-5 seconds
2. Exception catching should be written in fullThe following is a list of the most important of these, especially the connection errors and time-outs
3. Remember to release the IP after useDon't be a shithead.

def post_with_retry(url, data, retries=3):: for _ in range(retries): for
    for _ in range(retries).
        try.
             Get a new IP for each retry
            proxy = get_ipipgo_proxy()
            resp = requests.post(
                url, data=data, request.post()
                data=data,
                
                data=data, proxies=proxy, timeout=5,
                headers={'User-Agent': 'Mozilla/5.0'}
            )
            if resp.status_code == 200.
                return resp.text
        except Exception as e.
            print(f "Failed {_+1}th time: {str(e)}")
            time.sleep(2)
    return None

 The method to get the proxy (remember to replace your apikey)
def get_ipipgo_proxy():
    resp = requests.get("https://api.ipipgo.com/getip?套餐类型=dynamic_std&apikey=xxx")
    ip_data = resp.json()
    return {
        'http': f'socks5://{ip_data["ip"]}:{ip_data["port"]}',
        'https': f'socks5://{ip_data["ip"]}:{ip_data["port"]}'
    }

Guide to avoiding the pit (QA session)

Q: What should I do if my proxy IP always fails?
A: ipipgo's dynamic residential IP is automatically replaced by default in 15 minutes, if you find that it fails in advance, we suggest checking whether it triggers the wind control rules of the target website.

Q: POST submission is slow as a dog?
A: eighty percent of the agent nodes did not choose the right, ipipgo TK line suitable for high speed requirements of the scene, the measured delay can be pressed to 200ms or less.

Q: HTTPS website submission failure?
A: Check whether the proxy protocol is supported, ipipgo full package supports HTTPS/Socks5, remember to write the right protocol in the code.

The Doorway to Choosing a Package

Two final rants:Don't be cheap and use free proxiesThe key operation of data submission is to use regular service providers like ipipgo to be reliable. Their cross-border line in doing international business is particularly top, personally test the success rate of submission to 98% or more.
