Data Parser: Field Extraction and Conversion Tool

Hands-on with a proxy IP to turbocharge your data parser

Done the data crawl brother understand, the parser this thing is like an old car - encounter anti-climbing strict site, minutes to give you the whole lie down. This is the time to install aAgent IP TurboThe service, especially one like ipipgo that can change IPs in real time, can definitely make your data parsing efficiency take off in situ.

Why do I need a proxy IP for my parser?

Let's take a chestnut: you let the parser go to an e-commerce site to catch the price data, the first three times are smooth, the fourth time suddenly 403 blocked. At this time, if you hang on the ipipgo dynamic proxy, the system will automatically give you a new IP, just like the game to eat resurrection coins, the data continue to catch, completely without jamming.

 The death loop of the normal parser
for page in range(1,100):
    response = requests.get(f "https://xxx.com/page/{page}") page 4 must be blocked

 The correct way to hang a proxy
proxy = ipipgo.get_proxy() get new IP every time
headers = {'fake headers':'xxx'}
response = requests.get(url, proxies=proxy, headers=headers)

Practical Tips: Three Tips to Double Parsing Efficiency

Tip #1: IP Pool Rotation Strategy
Don't be stupid and use a single IP to tough it out, ipipgo's multi-million IP pool is not for show. Recommended settingsAutomatic IP switching every 5 requests, which makes it less likely to trigger a windshield control, but also ensures the speed of collection.

Tip #2: Precise Field Targeting
When using XPath or regular expressions, remember to saddle the parser with theIntelligent Fault ToleranceFor example, the product detail page of a certain treasure, use this positioning is correct. For example, the product details page of a certain treasure, use this positioning is accurate:

//div[contains(@class,'tb-detail')]//text() is compatible with various class tweaks

Tip #3: Abnormal Fuse Settings
Buried in the code is aDual Insurance MechanismIf you encounter a CAPTCHA or ban, automatically switch to ipipgo's higher stash proxy type while reducing the frequency of requests to save your life.

Common Pitfalls QA

Q: What should I do if I use a proxy IP and it slows down?
A: Eighty percent of the shared IP pool is used, change ipipgo's exclusive enterprise-class line, the speed can be stabilized within 20ms.

Q: What should I do if the field extraction always misses data?
A: First check if the website is revamped, then use ipipgo'sCity-level precise positioning IPSometimes a different regional IP can see a different version of the page.

Q: What can I do with a page that needs to handle JS rendering?
A: On Selenium + ipipgo's mobile IP combo, remember to set the User-Agent to disguise as a mobile browser.

Choose the right tool for the job

Used seven or eight proxy services and ended up locking up ipipgo just three points:
1. Self-developed IP revitalization technology, 24 hours without dropping the line
2. 300+ city nodes across the country
3. Customer service response is faster than 110, the last time I raised a work order at three o'clock in the middle of the night, I got a solution in five minutes.

Engaging in data parsing is like fighting guerrilla warfare, and ipipgo is your ammo dump. Recently, they are giving away a 5G traffic package to new users.Coupon Code: PARSE666You can also whore out three days of enterprise-level services for nothing.
