High-speed proxy server: High-speed IP proxy connection

First, the proxy IP in the end can help you solve what problem?

The most common proxy IPs that people use areInterception of data collection,Switching back and forth between multiple accounts,The crawler won't run.These bad things. To give a real example, a friend doing e-commerce with a crawler to catch the price of competing products, just catch two days to receive a platform warning, which is typical of IP address exposure.

At this time if you use ipipgo's dynamic residential IP, each request automatically change IP address, the platform simply can not distinguish between a real person operation or program running. Their IP pool covers more than 200 cities, and the 3 a.m. test can keep the response speed within 0.8 seconds, and this measured data is much stronger than many peers.

Second, what are the hard indicators to look at when choosing a proxy IP?

Here's a guide sheet for newbies to avoid the pitfalls:

Particular attention should be paid toIP Survival TimeThis hidden parameter, some service providers IP with two minutes on the failure. ipipgo's exclusive IP package can do 24 hours stable online, do long-term task is particularly suitable.

Third, the hand to teach you to configure high-speed proxy

Here's a practical example in Python, note the parameter setting details:

import requests

 Proprietary access information from the ipipgo backend
proxy = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
    'https': 'http://用户名:密码@gateway.ipipgo.com:9020'
}

 Key parameter settings
response = requests.get(
    'https://目标网站.com',
    proxies=proxy,
    timeout=10, don't exceed the proxy response timeout
    headers={'User-Agent': 'Mozilla/5.0'} Remember to add the browser logo.
)

If you get a connection timeout, check theWhitelistingThere is no binding of their own server IP. ipipgo background has a smart routing function that automatically assigns the nearest node, which can reduce the delay of 30% or more.

Four, white often step on the three big pits

1. Wrong type of package: Crawlers have to use dynamic packages, never buy a static IP
2. Concurrency overrun: The basic package can only run 10 threads at the same time
3. No IP rotation.: Set the switching frequency by adding the X-Proxy-Count parameter to the request header.

Previously, a user feedback that the proxy is not stable, and later found that his own program did not do the exception retry. It is recommended to addautomatic retry mechanismLike this:

from retrying import retry

@retry(stop_max_attempt_number=3)
def safe_request(url).
    try: return requests.get(url, proxies=proxy).
        return requests.get(url, proxies=proxy)
    except Exception as e.
        print(f "Request failed, auto-retry: {str(e)}")
        raise

V. Question-and-answer session

Q: Will I be recognized by the website if I use a proxy IP?
A: mainly look at the IP quality, ipipgo's residential IP are real users real network environment, comes with a browser fingerprint simulation, much more reliable than the server room IP.

Q: Why do I need to change my authorization information periodically?
A: This is a security protection mechanism, it is recommended to reset the account password in the ipipgo background once a month to prevent key leakage.

Q: What should I do if the latency of overseas nodes is high?
A: Check "Intelligent Route Optimization" in the control panel, the system will automatically select the nodes with latency lower than 800ms. If you are doing cross-border e-commerce, it is recommended to use their overseas private line package directly.

Six, these scenarios urgently need proxy IP

1. Avoidance of flow restriction in e-commerce price comparison
2. Social media multi-account management
3. Break the IP restriction when buying limited products.
4. Distributed deployment of the crawler
5. Advertisement effectiveness tracking tests in different regions

Recently, I found a new usage: using ipipgo's API interface to automatically change IP, with automation scripts to do 7×24 hour monitoring. A customer rely on this method to catch competitors change prices in the middle of the night, the next day immediately adjust the strategy, the month sales rose 15%.

At the end of the day, choosing a proxy service provider depends onlong term stabilitySome small service providers with the first two months is okay, after the IP pool began to shrink. ipipgo do six years old brand, technical support to respond quickly, the last two o'clock in the morning to mention the work order, ten minutes to solve the problem of the verification code recognition.
