Scripting proxy ip: code examples for setting proxy ip in various scripting languages

First, the script set proxy IP in the end what is the use?

We usually write scripts to capture data, do automated operations, often encountered site anti-climbing or IP blocked. At this time to the script to hang a proxy IP, just like the car installed a spare fuel tank - the main tank is blocked immediately switch to the backup, to ensure that the task is not interrupted. Especially with ipipgo this kind ofAbility to switch IP pools automaticallyThe service is the equivalent of putting unlimited fuel tanks in the script.

Second, the old driver of Python so hanging agent

Taking the requests library as an example, adding a proxy to the crawler takes only 3 lines of code. Note that the demo here is provided by ipipgo.Socks5 Protocol Proxy, measured to be more stable than the HTTP protocol:

import requests

proxies = {
    'http': 'socks5://用户名:密码@proxy.ipipgo.io:端口',
    'https': 'socks5://用户名:密码@proxy.ipipgo.io:端口'
}
response = requests.get('https://目标网站.com', proxies=proxies)

Key Note: Remember to change your username and password to the one generated in the ipipgo backend!Proprietary Forensic InformationDon't just use the placeholders in the example. If you get a certificate error, add the following to the requestverify=FalseParameter temporary solution.

Third, Node.js players look here

When sending requests with axios, there is a pitfall to be aware of when configuring the proxy. Many tutorials teach setting environment variables, but in practice it's more recommended to set theSpecifying a proxy within the code::

const axios = require('axios');
const HttpsProxyAgent = require('https-proxy-agent');

const agent = new HttpsProxyAgent({
    host: 'proxy.ipipgo.io',
    port: port number, auth: 'username', 'https-proxy-agent'; const
    auth: 'username:password'
});

axios.get('https://目标网站.com', {
    httpsAgent: agent, {
    proxy: false // This parameter must be added!
})
.then(response => console.log(response.data))

Special note: ipipgo'sTK line agentSuitable for high-frequency access scenarios, if you do data collection it is recommended to choose this package.

Fourth, Shell scripts can also play the agent

Command line tools such as curl and wget make it easier to set up proxies, and are especially handy for ad hoc testing:

export http_proxy="http://用户名:密码@proxy.ipipgo.io:端口"
export https_proxy="http://用户名:密码@proxy.ipipgo.io:端口"

 To test if the proxy is working
curl https://ip.ipipgo.io This address returns the current proxy IP.

Tip: ipipgo'sStatic Residential IPIdeal for scenarios that require a fixed IP, such as certain operations that require a login state.

V. QA First Aid Kit

Q: Proxy setting is successful but the request fails?
A: First check three elements: ① IP address with protocol header (such as socks5://) ② port is correct ③ account password is expired. If it doesn't work, go to ipipgo's backgroundConnection LogSee the specific errors reported in.

Q: How do I test that the proxy is actually working?
A: This test address is recommended:https://ip.ipipgo.ioIt can directly return the currently used exit IP and geographic location.

Q: What if I need to switch IP frequently?
A: Calling ipipgo's in codeAPI interfaceGet IPs dynamically and change proxies before each request. Their API return format isIP:Port:Username:PasswordJust disassemble and use it straight away.

Sixth, choose packages to look at the business scene

Based on our team's experience with real-world testing, we give a recommended comparison table:

Special note: When doing automation, it is recommended that you add theTraffic statistics moduleTo avoid over-utilization, ipipgo also provides real-time usage monitoring in the background, so remember to check it regularly.
