How to use proxy ip for website: website configuration proxy ip crawler solution

First, the proxy IP is a reptile oxygen tank to save life

Crawlers know that the website anti-climbing mechanism is now stricter than the airport security. Two days ago, an old man complained that he had just written a data collection script, which ran for less than half an hour and was blocked from the IP, and then he had to rely on the proxy IP to renew his life - to put it bluntly, it is to give the crawler a "face mask", so that the website thinks that each request is a different real person! The following is a list of the most important things you can do.

In the case of ipipgo, dynamic residential proxies are best suited for regular crawlers. Why? Because these IPs are real home broadband, and the characteristics of ordinary Internet users are exactly the same. For example, if you want to climb the price of e-commerce platforms, using this proxy is like the people in different cities across the country to check the goods, the site can not distinguish between a machine or a real person.

Second, three lines of code to get the proxy configuration

Don't be intimidated by those complicated tutorials, the actual configuration is simpler than you ordering takeout. First go to the ipipgo website to generate an API link, get the proxy address directly into the code. Here are two examples of common scenarios:

 Python requests version
import requests
proxy = {"http": "http://用户名:密码@gateway.ipipgo.com:端口",
         "https": "http://用户名:密码@gateway.ipipgo.com:端口"}
resp = requests.get('destination URL', proxies=proxy)

 Scrapy framework version
Add in settings.py:
DOWNLOADER_MIDDLEWARES = {
    'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 400,
}
Then in the crawler:
meta = { 'proxy': 'http://用户名:密码@gateway.ipipgo.com:端口'}

Third, choose the right package to save money

The ipipgo package looks like a lot, but really just remember this mantra:Dynamic for high-frequency visits, static for long-term tasks. Specifically:

Tested with dynamic residential agent to run data, a day can grips hundreds of thousands of non-blocking. If you encounter a particularly difficult website, directly on their TK line, the speed with the local direct connection.

IV. Guide to avoiding the pit (a must-see for whites)

Pitfall 1: Sudden failure of the agent - It is likely that the IP has been hacked by the target website. At this time to open the automatic switching function, ipipgo client can set every 5-10 minutes automatically change IP.

Pothole 2: Speed turns into a turtle - Check if you have chosen a node that is too far away geographically. For example, if you are crawling a domestic website, you should choose a proxy in Hong Kong or Taiwan, and the delay can be controlled within 200ms.

Pitfall #3: Accounts get winded - Don't log into multiple accounts at the same time with the same IP. Use ipipgo's Dedicated Static Proxy to bind a fixed IP to each account.

V. Quick questions and answers to frequently asked questions

Q: What's the difference between free proxies and paid ones?
A: It's like public toilets and your own bathroom. Free proxies are used by a lot of people who might have done something bad with it. ipipgo proxies are exclusive resources, clean and hygienic with "disinfection".

Q: Do I need to maintain my own IP pool?
A: No need at all! Their API automatically spits out available IPs, and the client can set up smart switching policies. All you have to do is copy the interface address into the code and leave the rest to the backend.

Q: What should I do if I encounter a CAPTCHA?
A: ipipgo's SERP API can directly return the rendered page data, bypassing the CAPTCHA. If you have to process it manually, it is recommended to lower the collection frequency to 2-3 times per minute.

The last thing I want to say is that a lot of websites are now on AI anti-climbing. Don't expect a set of proxies to go all over the world, it is best to mix dynamic and static proxies. ipipgo supports multiple protocols at the same time to configure, spread the traffic to different channels, which is the secret of the old driver's number.
