Introduction: Why do I need a no-fee proxy server IP?

Heck, as a veteran programmer, I know the importance of getting no-fee proxy server IPs in the online world. Fee-free proxy server IPs can help us bypass some regional restrictions and access blocked websites, they can also be used for crawling and data collection, and even for protecting our privacy from being tracked by websites. However, finding reliable no-fee proxy server IPs can be quite a challenging task. In this article, I will share some of my own tips and tricks to help you.

Get a proxy IP from a free proxy site

First of all, we can try to get proxy IPs from some free proxy sites. these sites usually update the list of available proxy IPs regularly, and we just need to keep crawling these lists, and we may find some available IPs. however, it is important to note that the stability and speed of free proxy server IPs are often not as good as paid high-quality proxy services, and there may be unstable connections or speeds that are slowdowns.

ipipgothon
import requests
def get_free_proxy():
url = 'https://www.free-proxy-list.net/'
response = requests.get(url)
if response.status_code == 200:
解析网页内容，提取代理IP和端口号
这里需要使用相应的解析库，比如BeautifulSoup或者正则表达式
proxies = parse_proxies(response.text)
return proxies
else:
print("Failed to fetch proxy list")
proxies = get_free_proxy()
print(proxies)

Using Proxy IP Pools

Another way to get no-fee proxy server IPs is to use a proxy IP pool. Proxy IP pools are maintained by a group of like-minded programmers who constantly acquire proxy IPs from various sources and regularly detect and filter the available IPs and then add them to the IP pool. We can get available proxy IPs by accessing the APIs of these proxy IP pools, such as free proxy IP pools like xroxy, hidemy.name, etc.

ipipgothon
import requests
def get_proxy_from_pool():
url = 'http://api.proxyprovider.com/'
response = requests.get(url)
if response.status_code == 200:
proxies = response.json()['proxies']
return proxies
else:
print("Failed to fetch proxies from pool")
proxies = get_proxy_from_pool()
print(proxies)

Regularly check proxy IP availability

Whether we get proxy IPs from free proxy sites or use proxy IP pools, we need to check the availability of proxy IPs on a regular basis. Because the stability of free proxy server IPs is not high, it is very likely that many IPs are already invalid or unavailable. We can test the connectivity and response time of proxy IPs by sending HTTP requests to the target website, so as to filter out the available proxy IPs.

ipipgothon
import requests
def check_proxy(proxy):
url = 'http://www.example.com/'
proxies = {
'http': 'http://' + proxy,
'https': 'https://' + proxy
}
try:
response = requests.get(url, proxies=proxies, timeout=5)
if response.status_code == 200:
return True
except Exception as e:
return False
假设proxies是一个代理IP列表
valid_proxies = [proxy for proxy in proxies if check_proxy(proxy)]
print(valid_proxies)

summarize

Getting no cost proxy server IPs is not an easy task and requires us to keep trying and exploring. By getting proxy IPs from free proxy sites, using proxy IP pools and regularly checking the availability of proxy IPs, we can increase the chances of getting usable proxy IPs. Of course, there are some risks associated with using free proxy server IPs, which may leak our private information or be recognized by websites and denied access. Therefore, when using free proxy server IP, we must pay attention to protect our privacy and security to avoid unnecessary losses.
