What the heck is an HTTP 403 error?
Crawlers or data collectors should have seen this abrasive little goblin - the browser suddenly pops up with a403 ForbiddenThe tip. Simply put, the website takes you as a suspicious element, just like entering the neighborhood was stopped by the gatekeeper not to enter. At this time, if you break in, they may directly pull the black IP, or even the entire IP segment are blocked.
Common trigger causes include:
1. Too frequent visits from a single IP (blitzing the site like a machine gun)
2. IP is flagged as a high-risk area (e.g., certain server room IP segments)
3. The requesting head is too distinctive (like going to the bank in a nightclothes to withdraw money)
What makes proxy IPs a breakthrough?
To give a chestnut, your downstairs fruit store owner recognized your face is not allowed to enter, this time to change clothes to wear a sunglasses can be mixed in. Proxy IP is the principle, through theConstantly switching network identities, making the site think it is being accessed by different users.

'https': 'http://username:password@gateway.ipipgo.com:8080'
}
requests.get("https://example.com", proxies=proxies)

Step 2: Setting the request interval
Which can't be gripped to death even with proxies, it's recommended to have a random delay of 1-3 seconds. Like this:
import time
import random
time.sleep(random.uniform(1, 3)) Random wait times are more natural
Step 3: Disguise the request characteristics
