First, proxy IP in the end is what the hell?
Let's imagine a proxy IP as a courier relay station. For example, if you buy a package from a friend's house, the courier will deliver the package there first and then transfer it to you. When using Python to make a web request, the proxy IP is the middleman that helps to "relay" the request so that the target website thinks that the request is coming from another address.
Here's the kicker:Not all proxy IPs are created equal! Just like the courier has ordinary pieces and cold chain fresh pieces, the proxy IP is also divided into dynamic residential, static residential and other types. For example, crawling data with dynamic IP is not easy to be blocked, long-term business with static IP is more stable.
Second, hand to teach you how to use Python to engage proxy IP
The most critical steps to understanding are straightened out first:Get proxy IP → test availability → apply to requestThe first thing you need to do is to get your hands on a dynamic residential IP address. Let's take ipipgo's Dynamic Residential IP as an example, they provide a ready-made API interface, so you don't have to toss your own server.
import requests
Sample API to get proxy IP from ipipgo (remember to change to your own account)
proxy_api = "https://api.ipipgo.com/get?type=dynamic&count=1"
Extract available proxies
def get_proxy():
resp = requests.get(proxy_api)
return f "http://{resp.text.strip()}" Returns something like http://1.2.3.4:8080
Initiate a request using a proxy
def visit_url(url).
proxies = {"http": get_proxy()}
return requests.get(url, proxies=proxies, timeout=10)
In practice
response = visit_url("https://target-site.com")
print(response.text)
Third, to avoid the pit commonly stepped on by novices
Seen too many people plant themselves in these places:
1. The proxy is not in the correct format:Note that the protocol header should be written in full, e.g. http://后面接IP和端口, a missing slash won't even connect it
2. Timeout not set:It is recommended to add a parameter such as timeout=10, otherwise the program will get stuck!
3. No IP testing was done:It's best to test the proxy before using it officially
Here's a code snippet that detects whether an agent is alive or not:
def check_proxy(proxy).
try.
test_url = "http://httpbin.org/ip"
resp = requests.get(test_url, proxies={"http": proxy}, timeout=8)
return resp.status_code == 200
except.
return False
Fourth, how to choose proxy IP in different scenarios?
It's important to pick the right type based on your business needs:
Dynamic residential (standard): Suitable for general data collection, $7.67/GB is a good deal!
Dynamic Residential (Business): Pick this one if you need higher anonymity, $9.47/GB with exclusive access
Static homesLong-term fixed business must have, 35 yuan / IP can be used for a whole month!
V. 6 Questions You Might Want to Ask
Q: What should I do if my proxy IP suddenly fails?
A: It is recommended to use ipipgo's auto-change API, their dynamic IP defaults 15 minutes to switch automatically
Q: What if I need a lot of IP?
A: Find their customer service to open the enterprise version, support batch acquisition and concurrency control
Q: Code runs slower?
A: Check whether the HTTPS site but with HTTP proxy, protocol mismatch will be slowed down!
Q: How can I prevent being recognized by the website?
A: ipipgo's TK line comes with camouflage features for difficult scenarios
Q: Does it support mobile development?
A: They provide APP client, both Android and iOS can directly call the agent
Q: What should I be aware of when using it for the first time?
A: Test with free trial quota first, IP switching in different regions may require whitelist reporting
VI. Tips for upgrading your gameplay
This is how old drivers play with proxy IPs:
1. Use with a random User-Agent to make the disguise more real
2. Important business with a dedicated static IP, to avoid the "neighbors" to do things
3. Setting up an automatic retry mechanism for failures, with a recommended maximum of three retries.
4. Regularly clean up logs, especially log files with IP records
Lastly, I'd like to say that choosing the right proxy service provider can really save you a lot of trouble. Like ipipgo support socks5 protocol, some special scenarios than HTTP proxy better use. Their API documentation is written in a clear way, and if you encounter problems, you can directly find the technical customer service, and the response speed is much faster than that of some big companies.
