Python Getting JSON Data: API Response Handling Tips

Can't get the API frequently called blocked? Try this proxy IP trick

When you are using Python to glean data, do you often encounter websites that suddenly turn their faces away from you? Especially those who want to frequently call the API interface, moving to give you a 429 error code. At this time, do not be stupid to use their own real IP hard just, or maybe directly be blacklisted.

To give a real case: last year to climb the price data of an e-commerce platform, the beginning of a direct request with the requests library, less than half an hour IP was blocked. Later, it was changed toDynamic Residential Proxy for ipipgoI've set up an automatic IP replacement policy, and I've been running it for three days without any problems. We'll talk more about this below.

Python request triple axe to be played this way

First to newbie friends throughout the basic template, veterans can look directly behind the advanced skills:

import requests

proxies = {
    'http': 'http://用户名:密码@gateway.ipipgo.com:端口',
    'https': 'http://用户名:密码@gateway.ipipgo.com:端口'
}

response = requests.get('Your API address', proxies=proxies, timeout=10)

Watch out for a few easy pitfalls:

1. Time-out settingsNever exceed 15 seconds, 8-10 seconds is recommended
2. Retry mechanismMatch at least 3 retries
3. Anomaly captureDon't just catch the Exception, break down the status code.

Six best practices for handling JSON responses

Getting the data is only the first step, the key is how to handle fast and stable. This enhanced processing solution is recommended:

Why do you recommend ipipgo?

The market is full of proxy service providers, but use them oripipgoMost reliable. Theirs.Dynamic residential agent poolThere are three killers:

1. Real user-level IP addresses that are not even visible as machine requests
2. Each IP can be used for up to 6 hours, which is 3 times longer than others.
3. Uniquely developed intelligent routing algorithm, automatically matching the fastest nodes

Last week to help a friend tune a government data interface, with ordinary proxy 10 requests were intercepted, replaced with ipipgoDedicated Government Corridor, 200 requests in a row are steady as an old dog.

Frequently Asked Questions QA

Q: What should I do if the proxy IP shows connection failure?
A: Check the whitelist settings first. ipipgo console has real-time authorization status display. If it does not work, immediately switch the alternate access point

Q：Returned data is always mutilated?
A: eighty percent of the site anti-climbing detected anomalies, it is recommended that the ipipgo background to open theRequest interval randomizationfunction to randomize the request interval to 3-8 seconds

Q: What if I need to handle millions of requests?
A: Directly on ipipgo'sEnterprise PackageIt supports multi-threaded concurrent requests, with a measured maximum of 5000 requests/minute.

A final word of advice: don't save money on proxy IPs, the free ones are basically pits. Like ipipgo new users have3-Day Free TrialIf you're not sure what you're looking for, it's best to try before you buy. After all, data security is no small matter, and saving that kind of money is not enough to wipe your ass.
