Do free proxy IPs work or not?
Many people think that free proxy IP is a bargain, in fact, this thing has to be said. Let's take the street to try to eat to play the analogy, taste a fresh no problem, but to rely on it to fill the stomach on the suspension. Recently in the technical forums to pull to a few free proxy can also be used, the first to everyone listed in case of emergency:
120.202.128.89:8080
183.247.211.50:30001
112.13.122.13:8085
These IPs have been tested to work, but there's no telling when they will.belchIt is recommended that you take a script and test the connectivity before you use it. I recommend that you take the script and test the connectivity before you use it, so you don't get blindsided when it's time to use it.
Three Pitfalls of Free Resources Don't Step Into
1. The problem of turtle speed: Last year, a crawler old brother with me to complain, using a free proxy to grab data, the result is slower than a snail crawl, and finally the project is yellow!
2. die suddenly: Last month there was an e-commerce company to engage in price monitoring, free agents with three days of the collective offline, almost a big mistake!
3. a safety hazard: There have been reports of malicious proxies stealing users' cookies, and it's no joke!
If it's a serious project, you still have to find a reliable service provider. Like us.ipipgoThe dynamic residential proxy, specialized in traffic encryption, response speed control within 200ms, much more stable than the free proxy.
Hands on how to verify agents
Here's a python detection script for the little guy to use directly:
import requests
proxy = {"http": "http://120.202.128.89:8080"}
try: resp = requests.get('', proxies=proxy, timeout=5)
resp = requests.get('http://httpbin.org/ip', proxies=proxy, timeout=5)
print(f "Currently in effect IP: {resp.json()['origin']}")
except.
print("This proxy is dead, move on to the next one!")
If I could see the script after the run.new IP address, indicating that the agent is working well. It is recommended to run tests every two hours to replace failed nodes in a timely manner.
Free Agent Advanced Play
1. Get it.agent poolAutomatic rotation (don't exceed 10 IPs, more than that will crash easily)
2. Addition of an important operationtimeout and retrymachine
3. Check IP's before sensitive operationsAnonymous rank
If it's too much trouble, just go ahead.ipipgoThe business solution comes with automatic IP switching and failover. Last time there was a customer doing cross-border e-commerce, using our API interface, it can run 8 million requests stably in a day.
QA time: a must for white people
Q: How long will the free agent last?
A: Depends on luck, fast hangs in a few minutes, long can last two days. Important items are recommended to use paid services
Q: How can I tell if an agent is safe?
A: 1. check the anonymity level 2. see if there is HTTPS support 3. detect the IP belongs to the region. If you really can't decide, you can useipipgoof exclusive agents, absolutely clean
Q: Why do you recommend ipipgo?
A: Three advantages after three years of self-use:
1. 国内有自建机房,低
2. Support for pay-per-use, how much is used?
3. Customer service response is fast, the last time there was a problem in the middle of the night, it was solved in 5 minutes.
Finally, the free agent is like a public restroom, emergency can be used, but do not use it as your own bathroom. If you really want to use it for a long time, you still need to use a reliable paid service, which is not only worrying but also safe. RecentlyipipgoIt's doing a 618 event with 30% off the first order for new users, so take a look at the website if you need to.
