How to set up a network proxy: HTTP/HTTPS/Socks5 proxy configuration steps in detail

Hands-on guide to configuring the three major proxy protocols

Getting the proxy settings for this thing is like assembling Legos, looking for the interface to put together on it. Let's not talk about false today, directly on the hands-on tutorials. Take ipipgo's proxy service, his family supports all the mainstream protocols, IP pool is as big as the Pacific Ocean, IP can be used around the world, the key is to configure it really does not bother.

Proxy settings in your browser

In the case of Chrome, for example, the three dots in the upper right corner →set up→ Search "proxy" → open the proxy settings. At this time, the system settings interface will pop up, do not panic, let's focus on the two HTTP and HTTPS.

After getting the proxy address in the ipipgo backend (e.g. 123.123.123:8888), fill in the corresponding location. Be careful toFill in both HTTP and HTTPS proxiesOtherwise, some websites may not load completely. Remember to check the "Verification Required" box if your service provider requires verification.

System Global Agent Configuration

Want all software to go proxy?Windows users pressWin+IOpen Settings→Network and Internet→Proxy→Manually set the proxy. Here is a pitfall to note: Socks5 proxy must be configured separately, the system comes with the settings only recognize the HTTP protocol.

This is the time to offer up a third-party tool, such as a program like Proxifier. Input the Socks5 address provided by ipipgo, and select the protocolSOCKS Version 5If it shows success when testing connectivity, the configuration is in place.

Programmer's Favorite Code Docking

If you're writing a crawler, look here. Adding a proxy in Python is a matter of three lines of code:

import requests
proxies = {'http': 'http://user:pass@ipipgo-proxy.com:port',
           'https': 'http://user:pass@ipipgo-proxy.com:port'}
resp = requests.get('destination URL', proxies=proxies)

If you want to use Socks5, you have to install therequests[socks]For this library, just replace the protocol header with 'socks5'. ipipgo's proxy supports long connections, so remember to raise the timeout when you're doing big data collection.

Guidelines on demining of common problems

Q: What can I do if the agent can't connect?
A: First check the three elements: IP, port, authentication information is correct. Then use telnet to measure the port pass or fail, if it is socks5 proxy, remember to verify whether it supports TCP protocol!

Q: What is the speed difference between different protocols?
A: HTTP is the fastest and Socks5 is the most compatible. Like ipipgo this support UDP forwarding big factory, under the BT seed with Socks5 more stable!

Q: What if I need to change IP frequently?
A: Open in the backend of ipipgoDynamic Residential AgentsWhen writing code, remember to set the retry mechanism to avoid short interruptions due to IP changes.

Lastly, I'd like to say a few words: if you want to choose a proxy service, you have to look at the protocol support, just like buying a cell phone, you have to look at the network standard. ipipgo has done a good job with this, so you can use all the protocols, and you don't have to worry about the purity of the IPs. If you encounter a website with a lot of CAPTCHA, it is recommended that you go to his residential IP, and the success rate can be much higher.
