How to set the proxy ip?

When you are doing web crawling, data collection or visiting some blocked websites, you often need to use proxy ip to hide the real visitor's ip address. So how to set up a proxy ip? The next step is to introduce it in detail.

How to set proxy ip

Step 1: Get proxy ip

Before setting up a proxy ip, you first need to get an available proxy ip. you can buy a paid proxy ip through some proxy ip providers, or you can get a free proxy ip through some free proxy ip websites. whether it's a free proxy ip or a paid proxy ip, you need to make sure that the stability and reliability of the proxy ip is guaranteed.

Step 2: Set up proxy ip

When using Python for web crawling, you can use the requests library to set the proxy ip. the specific code is shown below:

"`ipipgothon
import requests

proxy = {
"http": "http://your_proxy_ip:port",
"https": "https://your_proxy_ip:port"
}

url = "https://www.example.com"
response = requests.get(url, proxies=proxy)
print(response.text)
“`

In the above code, the proxy ip is replaced with the actual proxy ip address and port, and then the proxy ip is set by setting the proxies parameter.

How to set proxy ip to close automatically

Sometimes when we are using proxy ip, we want to disable proxy ip automatically under certain conditions, which can be realized by the following code:

"`ipipgothon
import requests

url = "https://www.example.com"
proxy = {
"http": "http://your_proxy_ip:port",
"https": "https://your_proxy_ip:port"
}

def get_content(url, proxies=None).
if proxies.
response = requests.get(url, proxies=proxies)
else.
response = requests.get(url)
return response.text

content = get_content(url, proxy)
print(content)

# Disable proxy ip under certain conditions
# content = get_content(url)
# print(content)
“`

In the above code, a get_content function is defined to realize the encapsulation of the access url, the proxy ip is set by passing the proxies parameter, and when the proxy ip is not needed, the proxy ip parameter can be not passed, so as to realize the effect of automatically turning off the proxy ip.

With the above methods, we can flexibly set and automatically disable proxy ip to realize a more intelligent and stable proxy ip usage.
