Get the IP of the proxy server

In network access, sometimes we need to get data through a proxy server, and knowing the IP address of the proxy server is a very critical step. The following will introduce how to get the IP address of the proxy server through Python code.

First, we need to install the requests library, if you haven't already done so, you can do so with the following command:

"`ipipgothon
pip install requests
“`

Next, we can use the following code to get the IP address of the proxy server:

import requests

def get_proxy_ip(proxy_url):
response = requests.get(proxy_url)
# Assuming the proxy server returns data in json
proxy_ip = response.json()['ip']
return proxy_ip

proxy_url = 'http://your_proxy_server_url'
proxy_ip = get_proxy_ip(proxy_url)
print("The IP address of the proxy server is: ", proxy_ip)

In the above code, we define a function called get_proxy_ip which accepts the address of the proxy server as a parameter and returns the IP address of the proxy server. We then use the requests library to send a GET request for the data returned by the proxy server, assuming the data is returned in json format, from which we extract the IP address and return it.

Using a proxy server address

After getting the IP address of the proxy server, we can apply it to our network request to realize the purpose of accessing network resources through the proxy server. Here is a simple example:

ipipgothon
import requests

proxy_ip = '127.0.0.1' # 假设这是我们得到的代理服务器IP地址
proxy = {
'http': 'http://' + proxy_ip,
'https': 'https://' + proxy_ip
}

url = 'http://example.com'
response = requests.get(url, proxies=proxy)
print(response.text)

In the code above, we defined a variable named proxy_ip that stores the IP address of the proxy server we obtained. Then we constructed a dictionary named proxy that contains the IP address of the proxy server and specifies the http and https proxies respectively. Finally, we sent a GET request with the proxy through the requests library, which accessed the specified url through the proxy server and printed the data returned by the request.

With the above steps, we have successfully obtained the IP address of the proxy server and learned how to use the proxy server address for network requests. I hope this article will be helpful to you.
