How to set up proxy IP for reqests library

Today I want to share a question with you about how to set proxy IP for requests library. As you know, when we use the requests library to send network requests, we can set the proxy IP to hide our real identity to protect privacy or bypass some restrictions. So, how to set proxy IP for requests? Let me answer all the questions for you.

I. What is a proxy IP

Before we start explaining how to set up a proxy IP, let's first understand what a proxy IP is.A proxy IP, as the name suggests, is an IP address that replaces ours for web requests. It can hide our real IP address, making it impossible for the target website of the request to trace our real identity. At the same time, proxy IP can also be used to bypass some restrictions, such as IP access frequency restrictions, IP region restrictions and so on.

Of course, proxy IP is not omnipotent, some websites may block some common proxy IP addresses, so we need to choose a stable and reliable proxy IP to make requests.

Second, how to get the proxy IP

If you want to use a proxy IP, first we need to get some available proxy IPs. here I recommend two ways to get them, one is to buy a proxy IP, and the other is to get a proxy IP for free. the following are introduced.

1. Purchase a proxy IP

To get a stable and reliable proxy IP, buying a proxy IP service is the best choice. There are many proxy IP providers in the market and we can choose the right one according to our needs. After purchase, the provider will provide us with some proxy IP addresses and port numbers which we can use for our requests.

2.Free proxy IP

If you don't want to pay for a proxy IP for the time being, you can also choose some free proxy IP websites to get it. These websites will update some available proxy IPs regularly and we just need to choose the right IP address from them.

Third, the use of requests to set the proxy IP

After getting the proxy IP, we can use the requests library to set the proxy IP. Below I will combine some code samples to demonstrate how to set the proxy IP.

1. Use HTTP proxy IP

If the proxy IP you get is of HTTP type, we can set the proxy IP with the following code:

import requests

proxies = {
"http": "http://12.34.56.78:8888",
"https": "http://12.34.56.78:8888",
}

response = requests.get(url, proxies=proxies)

Where `http` and `https` represent the protocol type of the request respectively, `12.34.56.78` represents the address of the proxy IP and `8888` represents the port number of the proxy IP. We just need to replace the proxy IP address and port number with the ones we got.

2. Use SOCKS proxy IP

Some proxy IPs are of SOCKS type, for this type of proxy IP, we can set it with the following code:

import requests

proxies = {
"http": "socks5://12.34.56.78:8888",
"https": "socks5://12.34.56.78:8888",
}

response = requests.get(url, proxies=proxies)

Again, just replace the proxy IP address and port number with the one you got.

Fourth, the precautions of setting proxy IP

When setting up a proxy IP, we need to pay attention to the following points:

1. Verify Proxy IP Availability: Not all proxy IPs are available, some may have expired or been blocked. Therefore, we need to verify the availability of the proxy IP when using it, you can send a simple request to check if you can successfully access the target website.

2. Regularly replace the proxy IP: Since the proxy IP may fail, it is recommended to regularly replace the proxy IP after using it for a period of time to ensure the stability of the request.

3. Choose the appropriate proxy IP type: Proxy IP is divided into HTTP and SOCKS types, according to the needs of the request to choose the appropriate proxy IP type.

summarize

Through the introduction of this article, I believe you have a certain understanding of how to set the proxy IP of the requests library. In practice, we can choose a suitable proxy IP to send network requests according to our needs. At the same time, we also need to pay attention to the availability of the proxy IP and the issue of regular replacement. I hope this article will be helpful to you.
