High success rate http proxy: high success rate HTTP proxy optimization settings

Hands-on teaching you to tune HTTP proxy success rate

Brothers engaged in network crawlers understand that the proxy IP two winds in three days can drive people crazy. Today we nag some real, teach you how to HTTP proxy success rate from 50% dry to 90%+. First, remember this mnemonic:Choose the right path + change vests diligently + good medical checkup = high success rateThe

First, selecting IP is similar to selecting an object

Don't be cheap and buy a bad IP, especially the kind that claims to be free and full. Take ipipgo's dynamic residential (standard version), more than 7 yuan 1G price is really not expensive, the key is that their family IP are the carrier's real server room resources. Here is a comparison table:

To give a chestnut, brothers who do e-commerce comparison use dynamic IP, each request to change a new vest; do overseas social media operations with static IP, raising the number is not easy to be wind control.

Second, the agent set up to pay attention to the door

Many people fall prey to timeout settings, remember this golden combination:Connection timeout 3 seconds + read timeout 10 secondsThe old Python guy could have written it this way:

import requests

proxies = {
    'http': 'http://user:pass@gateway.ipipgo.com:9020',
    'https': 'http://user:pass@gateway.ipipgo.com:9020'
}

resp = requests.get('Target URL',
                   proxies=proxies, timeout=(3, 10)
                   timeout=(3, 10))

Note: Don't use the default timeout for requests! Don't use the default timeout of requests, that thing can't move and get stuck. ipipgo's API extraction remember to add automatic switching, it is recommended to change the IP every 20 requests.

Third, these pits must not be stepped on

1. Don't be lazy, User-Agent.: Have at least 50 sets of UA's from different browsers to rotate through
2. Take it easy on the request frequency.3-5 seconds between human operations. Don't make it look like a robot.
3. Exception handling should be in place: Change IP immediately when you encounter 403/503, don't fight with the website!

There's a tawdry operation to teach you: use ipipgo's TK line agent to take the carrier level channel. Last time there was a brother who did logistics tracking, the success rate directly soared from 68% to 93%.

IV. Practical QA First Aid Kit

Q: What should I do if my proxy IP is always banned?
A: Change static residential IP, $35/month fixed IP, with UA camouflage + behavior simulation package

Q: What about high latency on overseas websites?
A: open ipipgo cross-border line, select the target country local export node, the speed can be 3 times faster!

Q: API extraction always fails?
A: Check three things: ① whitelist IP is bound ② authorization method is not right ③ extract format json or text

Fifth, choose the service provider to see the doorway

Why do you recommend ipipgo? people are really willing to spend money on resources:
- 200+ countries local carrier resources, unlike some service providers to take the IP room to fill the number of
- Support HTTP/HTTPS/Socks5 three protocols seamless switching
- The client comes with intelligent routing, automatically selecting the fastest node

Finally, a cold knowledge: their dynamic enterprise version of the proxy, although more expensive ($9.47 / G), but with automatic retry and intelligent routing, suitable for teams doing large-scale data collection.
