How to set up http proxy ip? Browser, system, code three level configuration tutorial

Browser Settings: Hands-on Proxy Hanging

Let's start with the simplest browser configuration, using Chrome as an example. Open the upper right corner of the three points → Settings → Advanced → System → open the proxy settings, which will jump to the system settings interface (do not panic, later will talk about system-level configuration). However, it is more recommended to install a SwitchyOmega plugin, this magic tool can directly manage the proxy.

In the plugin, create a new scenario mode and select the proxy server type. Be careful here:ipipgo's proxy address depends on the protocol typeFor example, a dynamic residential proxy may look like this: gateway.ipipgo.com:3000, fill in the account password and you're done. If you encounter slow loading websites, remember to add domestic websites to the "list of non-proxy addresses" so that you can swipe Taobao without going through a proxy.

// Example configuration (don't copy directly, use your own account)
Proxy server: gateway.ipipgo.com
Port: 3000
Authentication method: username/password
Account: your_username
Password: your_password

System-level agents: a one-and-done configuration approach

Windows users press Win+R and type control to open Control Panel → Network and Internet → Internet Options → Connections → LAN Settings. Here's a pitfall:Don't check the "auto-detect settings" box.Otherwise the system will blindly mess with your proxy configuration. Fill in the proxy address provided by ipipgo. It is recommended to configure both http and https protocols.

Mac users go to System Preferences → Network → Advanced → Proxies, where you can see the five proxy types. Focusing on the two, SOCKS5 and HTTP:SOCKS5 is recommended for dynamic homesIf you want to use HTTP, you can choose HTTP for your static residence to make it more stable. Remember to click "OK" to save after configuration, don't click the cancel button more than 10 times like the old king did last time.

Code Configuration: A Programmer's Pose Only

Using Python's requests library as an example, proxy configuration is really just two lines of code. However, you have to be careful about session retention, especially if you are using a dynamic residential IP, you have to set the session expiration date.

import requests

proxies = {
    'http': 'http://user:pass@gateway.ipipgo.com:3000',
    'https': 'http://user:pass@gateway.ipipgo.com:3000'
}

resp = requests.get('https://example.com', proxies=proxies, timeout=10)

If you're doing a crawler project, it's recommended to go toSERP API for ipipgoThe first thing I want to do is to use a proxy pool to maintain the proxy pool. Their API supports 100+ requests per second, comes with a failure retry mechanism, much more stable than the bare proxy.

The Complete Guide to Stepping in the Pit: A Must-See QA for Newbies

Q: I can't open the webpage after setting up the proxy?
First ping the proxy address to see if it passes, and then use curl to test connectivity. ipipgo has real-time usage statistics in the background, so you can see if the account is in arrears.

Q: How do I choose between dynamic and static packages?
If you need to change IP frequently, choose dynamic (such as crawlers), long-term fixed business with static (such as overseas live broadcast). ipipgo's dynamic packages support rotation interval settings, the lowest to 30 seconds to change IP once.

Q: How do I switch proxies automatically in the code?
Use their API to get the latest list of proxies. it is recommended to work with proxy middleware. the Python scrapy framework can be configured like this:

class IpipgoProxyMiddleware.
    def process_request(self, request, spider).
        request.meta['proxy'] = 'http://gateway.ipipgo.com:3000'
        request.headers['Proxy-Authorization'] = basic_auth_header('user', 'pass')

Choosing the right package: three years less travelling

ipipgo's.Dynamic residential (standard)Suitable for individual developers, 5GB of traffic to start enough to test a small project. Enterprise-level users directly on the dynamic residential (Enterprise Edition), support for API batch management + custom IP pool. Do TikTok old iron closed eyes into their TikTok solution, the actual test live delay can be pressed to within 200ms.

Finally, a piece of cold knowledge: when you configure the proxy to DNS resolution also take the proxy channel, you can avoid DNS pollution problems. Add this line in the code:

requests.get(url, proxies=proxies, headers={'Host': 'real domain'})

If you still can't get it to work, go directly to ipipgo's tech support. Their customer service response speed is faster than SF Express, the last time I raised a work order at three o'clock in the morning, five minutes to solve the problem of the proxy pool offline.
