Hands-on with API Proxy IPs

Recently, many friends asked how to use the API to engage the proxy IP, today we will nag some real. Suppose you are a shoe merchant, want to see the price of peers, manual check must be exhausted, then you have to rely on the program to automatically grab the data. But direct dislike of other people's websites, minutes to be blocked IP, this time the proxy IP is your lifesaver.

I. What is an API proxy?

Simply put, it's like anegotiatorThe program will help you to turn the request around. For example, you want to check a website data, the program first connected to ipipgo's server, change body "armor" and then go to visit the target site. This not only to protect their own real IP, but also to break through access restrictions, especially the need for a large number of repeated operations is particularly useful.

import requests

 As a chestnut, Python calls the proxy API
proxy = {
    "http": "http://username:password@gateway.ipipgo.com:9020",
    "https": "http://username:password@gateway.ipipgo.com:9020"
}

response = requests.get("destination URL", proxies=proxy)
print(response.text)

II. Four steps to actualization

1. Go to the ipipgo website firstSign up for an account.500 free trials for newcomers
2. Find on the consoleAPI Access Documentation, remember these three things:
- Access address (like gateway.ipipgo.com)
- Account Password
- Port number (9020/9021 in different packages)
3. According to the document to write code, it is recommended that the first test interface to try the water
4. Before the official start, remember to add aerror retry mechanismIt's normal for the network to jerk around.

III. Common pitches for novices

IV. Experience packages for veteran drivers

1. For crawlers, it is recommended to chooseDynamic Residential AgentsThe success rate of this package can go up to 981 TP3T.
2. Set a random waiting time, don't send requests like a machine gun.
3. Important data to remember to dolocal cacheTo prevent the number of wasted duplicate requests
4. Don't fight hard when encountering CAPTCHA, use the coding platform to cooperate with it.

V. QA on high-frequency issues

Q: What's the difference between free proxies and paid ones?
A: Just like public restrooms and their own bathroom, the free ones don't cost any money but may suddenly cut off the flow, ipipgo's paid agents have exclusive access, and the speed is steady as a batch.

Q: How can I tell if a proxy is in effect?
A: Visit https://ip.ipipgo.com这个地址 to see the current exit IP in use and also to check the attribution.

Q: What if I want to send many requests at the same time?
A: Use ipipgo's concurrency package, which supports multi-threading, and remember to set reasonable intervals, so you don't crash people's servers.

Finally, to say a big truth, the proxy IP this thing three parts rely on tools and seven parts rely on strategy. The main reason I chose ipipgo is because of his family.Dynamic IP pool large enoughThe situation of IP collision will not occur. In particular, brothers who do e-commerce price comparison, with his API access, data collection efficiency directly doubled, no longer have to stay up late to manually refresh.
