PythonEbay Capture Tool: Auction Data Collection

Why do I have to use a proxy IP to climb Ebay?

The old iron have engaged in data collection know that Ebay's anti-climbing mechanism is more strict than the cell access control. To give a chestnut, you take your own broadband even climb half an hour, light speed limit heavy blocking IP. last week a buddy do not believe in evil, with their own computers directly connected to climb the product details page, the results of the next day to find their own IP was blacklisted, even normal browsing are not allowed.

at this momentproxy IPIt's your savior. It's like changing different clothes every time you go out so the doorman doesn't recognize you. Especially with professional services like ipipgo, you change different exit IPs for each request, and Ebay's defense system simply can't catch the pattern.

Second, Python practice: to the crawler put on the "cloak of invisibility"

Here's the whole code that really runs for the guys, notice the proxy settings bit:

import requests
from itertools import cycle

 The format of the proxies provided by ipipgo Remember to replace them with your own accounts
proxy_list = [
    'http://用户名:密码@gateway.ipipgo.com:20000',
    'http://用户名:密码@gateway.ipipgo.com:20001',
     Add more IPs here
]

proxy_pool = cycle(proxy_list)

def fetch_auction(item_id):
    for _ in range(3): failed to retry 3 times
        current_proxy = next(proxy_pool)
        current_proxy = next(proxy_pool)
            resp = requests.get(
                f'https://www.ebay.com/itm/{item_id}',
                proxies={'http': current_proxy}, timeout=10
                timeout=10
            )
            return resp.text
        except Exception as e.
            print(f "Request with {current_proxy} failed, move to next one")
    return None

 Example of use
print(fetch_auction('123456789'))

take note ofrecount (e.g. results of election)Here we go:
1. ipipgo's proxy address with account password authentication
2. Automatic IP switching with cycle polling
3. Don't set the timeout more than 10 seconds, otherwise it will affect the efficiency.

Third, avoid the collection of minefields of the three great tips

These potholes are summarized based on our experience in dealing with problems for our clients:

IV. Experiences of veteran drivers

Do not think that the use of agents is all right, these details do not pay attention to the car as usual:
- 3am to 8am is prime collection time (low foreigner activity)
- No more than 500 requests per IP per day
- Encountering images loading with ipipgo's static residential IP is more stable
- Never use free agents, nine out of ten are pits

V. Frequently Asked Questions QA

Q: Will I be blocked by Ebay if I use a proxy IP?
A: rational use will not, the key to do: 1) IP quality is excellent (recommended ipipgo exclusive IP) 2) control the frequency of requests 3) with random hibernation

Q: Is it illegal to collect auction data?
A: Compliance with robots agreement + does not involve user privacy data collection, belongs to the scope of normal market research. However, it is recommended to operate under the protection of ipipgo proxy to be more secure!

Q: Why do you recommend ipipgo?
A: They have a special optimized line for the e-commerce platform, the measured capture success rate of 98%, more stable than ordinary agents is not a half a star. Especially the auction countdown such as the need for real-time monitoring of the scene, with their dynamic IP pool basically did not fall off the chain!

Finally nagging, data collection is a fine job, the tool with the right half the effort. Recently see ipipgo in doing activities, new users to send 5G flow, there is a need to try, than self-tossing to save a lot of heartache.
