How to match HTTP proxies? Hands-on teaching you quickly get started
Many friends just contact HTTP proxy, always be a variety of parameter settings to get a big head. Today, we will break up the crumbs to say, how to use ipipgo's proxy service fast configuration. First remember the three core parameters:IP address, port, authentication information, these three are like the door number + key to your house.
import requests
proxies = {
"http": "http://用户名:密码@ProxyIP:Port",
"https": "http://用户名:密码@proxyIP:port"
}
response = requests.get("http://目标网站", proxies=proxies)
It's as simple as that with Python, note that ipipgo has a special authentication method with a password ofdynamically generatedYou can see the real-time key in the user center, don't copy the example code in the tutorial directly!
Three Top Tips for Protocol Optimization
First move:Long Connection Multiplexing. Switching connections on and off frequently is particularly resource-intensive. it is recommended to set the Keep-Alive parameter. Like this:
headers = {'Connection': 'keep-alive'}
Second move:Dynamic adjustment of overtime. Don't be silly with fixed timeouts and flexible settings based on business scenarios:
| Business Type | Recommended timeout (seconds) |
|---|---|
| data acquisition | 15-30 |
| real time interaction | 5-8 |
Third move:Intelligent retry mechanism
.. Retry automatically when you encounter network fluctuations, but don't loop mindlessly! It is recommended to use the exponential backoff algorithm and wait for intervals like 1 second → 3 seconds → 9 seconds. QA 1: What should I do if the agent suddenly fails to connect? QA 2: Is it normal for the speed to be fast and slow? QA 3: How can I tell that the proxy is in effect? A point of emphasis for the novice: Finally, there is an easy pitfall: many tutorials teach you to configure global proxies in the system settings, but don't do it! This will send all traffic through the proxy. The correct way to do this is to use the following in the codecallIf you are using ipipgo, you can use their client tool to automatically differentiate between direct and proxy traffic. If you use ipipgo, their client tools have intelligent routing function, automatically distinguish between direct connection and proxy traffic, this is really convenient.First aid kit for real-world problems
First check three elements: whether the IP is expired (ipipgo's dynamic residential IP is valid for 1 hour by default), whether the port is correct, and whether the key is updated. If all are OK, try a different protocol, such as HTTPS cut to HTTP
It depends on the package chosen. Dynamic residential IP goes to real home bandwidth, which may fluctuate during peak hours. If you need high stability, we recommend using ipipgo!Static Home Package, 35 bucks a month for a fixed IP with solid speeds like an old dog.
