Proxy ip api: proxy API interface docking development tutorials

Teach you to play with proxy IP interface docking

Recently, many friends engaged in crawler development are asking how to quickly dock the proxy IP API interface. Today we will talk about this matter in the vernacular, to ensure that you can get started on the operation after reading. First do not rush to write code, you have to understand a few key points.

First you have to understand.How Proxy IP works. Simply put, through a third-party service provider (such as ipipgo) to provide an interface, real-time access to available IP addresses. These IPs are distributed in different regions, which can help our program to disguise as users from different regions to visit the target website.

 Python sample code (remember to replace the API key with your own)
import requests

def get_proxy().
    api_url = "https://api.ipipgo.com/getip?key=你的密钥&count=1"
    response = requests.get(api_url)
    return response.json()['data'][0]

There are four steps to interface

1. Register for an account: Open an account on the ipipgo website, we recommend trying the waters with the pay-per-use package first. New users now have 5 dollars of experience money, enough to test a hundred or so requests.

2. Selection of docking method: Their home supports three modes, see the table below:

3. Parameter Configuration: Focus on these parameters:

• Protocol type (HTTP/HTTPS/Socks5)
• IP survival time (3-30 minutes optional)
• Geographic filtering (supports city-level positioning)

// PHP example (with geographic filtering)
$api = "https://api.ipipgo.com/getip?key=密钥&city=上海&protocol=http";

4. Exception handling: It is suggested to add a retry mechanism to each request, and automatically replace the IP when it fails. The test found that adding a 3 retries, the success rate can be more than 99%.

Early warning of common potholes

Recently I found a couple of typical problems when I was helping a customer with debugging:

• Don't set the timeout to more than 10 seconds, or it will affect the efficiency
• Remember to turn off SSL certificate validation (development environment)
• Open a connection pool for high concurrency scenarios, don't be stupid and create a new connection every time!

There is a friend doing e-commerce, did not pay attention to the frequency of IP switching, the result triggered the anti-climbing mechanism. Later changed to use ipipgoIntelligent Rotation ModelThe problem is solved immediately.

QA time

Q: What should I do if my proxy IP suddenly fails?
A: First check whether the authorization is correct, and then use diagnostic tools to test IP connectivity. If it fails frequently, it is recommended to switch ipipgo's exclusive static package

Q: What can I do about slow access?
A: 1. choose the nearest geographical node 2. switch to socks5 protocol 3. check the local network latency

Q: How do I choose a package for my enterprise level needs?
Recommended by ipipgoDynamic Residential (Enterprise Edition)The company supports concurrent authorization + customized geographic distribution. The last time a financial company deployed a cross-border line, the average daily processing of 500,000 requests steady.

Why recommend ipipgo

After using 7 or 8 proxy providers, I ended up using ipipgo for the long term mainly for these reasons:

• Transparent pricing with no setups, more than $7 for 1G of traffic for dynamic residences
• Technical support responds quickly, the last time I raised a work order at 3:00 a.m., it was actually returned in seconds!
• Full protocol support, even the cold socks5 are perfectly compatible with the

Especially theirTK LineI'm not sure how hard it is to do business overseas. Before testing the IP pool of a country in Southeast Asia, the availability rate can reach 92%, which is considered the top level in the industry.

Lastly, docking APIs is not a one-time thing. It is recommended to do a health check every month, update the SDK version, and adjust the IP policy in time. If you are not sure what to do, you can directly find ipipgo's technology, they can give custom optimization solutions.
