First, why is the comment crawler always blocked? First look at the IP exposure
Friends who engage in social media sentiment analysis understand that the crawler scripts that are painstakingly written are not moved and are blocked by the platform. Many people's first reaction is the account registration problem, in factMore than 60% blocked all because the IP was identifiedThe website's wind control system is not watching you. Imagine: you use your own broadband IP to furiously brush thousands of comments every day, the website wind control system does not stare at you to stare at who?
Recently, an e-commerce friend planted in this: he climbed the competitor store comments, with a fixed IP continuous request, the result is that within half an hour the account is completely destroyed. Later, he switched toDynamic Residential Proxy for ipipgo, spreading the requests over 200 city IPs and running them for three days in a row without triggering the windshield.
Second, the proxy IP anti-blocking of the three major tricks
Tip #1: Pick the right IP type
Data center IPs are cheap but high-risk (easy to identify), residential IPs are expensive but secure. Recommendationsmix: Ordinary data collection with data center IP, the core account operation cut residential IP. like ipipgo's hybrid proxy pool, can automatically switch between the two types of IP, than a single program to save 30% cost.
Tip #2: Behavioral fingerprints should be messed up
| dangerous behavior | Camouflage program |
|---|---|
| Fixed Interval Request | Randomized delay of 3-15 seconds |
| Single Browser Fingerprinting | Using ipipgo's companion UA randomizer |
| IP geolocation mutation | Enable IP address trace simulation |
Tip #3: There's something to be said for decentralizing traffic
Don't put your eggs in one basket! Simultaneous configurations are recommended:
- IP rotation of the three major domestic carriers
- Segmented collection of IPs from different cities (e.g., use Guangdong IPs in the morning and cut Zhejiang IPs in the afternoon)
- Daily usage per IP not to exceed 10 times that of a regular user of the platform
Third, the hand to configure ipipgo agent
Take the Python crawler as an example of a three-step access protection:
1. Create a "Sentiment Analysis" project in the ipipgo backend and get the API key.
2. Install the official SDK:pip install ipipgo-client
3. Code configuration example:
import requests
from ipipgo import RotateProxy
proxy = RotateProxy(
api_key="Your key",
region=["Shanghai", "Beijing", "Guangzhou"], Specify IP Region
protocol="http"
)
for page in range(1,100): resp = requests.
resp = requests.get(
url="Target site link", proxies=proxy.next())
proxies=proxy.next() auto IP change
)
Remember to add random delays!
time.sleep(random.randint(2,8))
iv. guide to demining common problems
Q: What should I do if I use a proxy IP and still get blocked?
A: Check three points: ① IP purity (recommended ipipgo business-class proxy) ② request header with a real browser fingerprint ③ operation interval is too regular
Q: How much IP volume is needed to be safe?
A: daily picking within 10,000, 50 IP is enough; more than 50,000 recommended 200 + IP pool. ipipgo's elasticity package supports expansion at any time, suitable for fluctuations in the amount of demand.
Q: How do I cope with the platform's sudden upgrading of wind control?
A: Immediately turn on ipipgo'sDeep camouflage modeThis feature will synchronize the update of the latest anti-climbing strategy and automatically adjust the IP switching frequency and request parameters.
V. Long-term protection also depends on the service provider
Don't just look at the price when choosing an agency service, focus on the inspection:
- IP survival hours (ipipgo residential IPs survive for an average of 6 hours)
- Connection Success Rate (they have a 99.2% success rate guarantee at home)
- Whether to provide supporting anti-anti-crawling tools
- Does the API support intelligent route switching
Last week to help customers deploy crawler system, with a certain cheap proxy three days to be recognized. I switched to ipipgo.Enterprise Customized SolutionsAfter that, not only stable operation for two weeks, the collection efficiency has been improved by 40%. the key is that they have a dedicated technical support team, encountering problems can quickly adjust the strategy.
Final reminder: don't save a little money on account wind control, the loss of business interruption caused by a single blockage far exceeds the cost of the proxy IP. Choose the right service provider + configuration in order to make the sentiment analysis project run steady and fast.
