Coursera Dataset: API Methods for Legitimate Access to Course Information

How do real users glean Coursera course data?

A buddy in education research recently approached me to complain that he wanted to batch analyze Coursera's course rating data, but ended up getting blocked just after grabbing two pages of IPs. This scene is familiar, right? To put it bluntly, the platforms are loaded withIntelligent Risk Control RadarThe same IP high-frequency access to the direct black.

The right way to open the official API

Coursera actually hides the official data interface (https://api.coursera.org), which can be whored out by signing up for a developer account. But beware of three things:

Highlighted in the applicationAcademic research purposes, attaching the .edu extension to the email directly doubles the success rate. Remember to bring a proper User-Agent in the request header, don't use Python's default, it's easy to be treated as a crawler.

A real-world survival guide to proxy IPs

Use ipipgo's residential agent as a demo, their homeDynamic IP PoolIt is especially suitable for this kind of scenario where frequent switching is required:

import requests
from itertools import cycle

proxies = cycle([
    'http://user:pass@gateway.ipipgo1.com:8000',
    'http://user:pass@gateway.ipipgo2.com:8000', [ ]proxies
     More proxies here...
])

for page in range(10).
    current_proxy = next(proxies)
    response = requests.get(
        'https://api.coursera.org/courses',
        proxies={'http': current_proxy},
        headers={'Authorization': 'Bearer YOUR_API_KEY'}
    )
     Processing data logic...

Here's the point:Must change IP for each requestIt is recommended to set an interval of 3 seconds or more. ipipgo's proxy comes with aAutomatic failoverThe function will automatically switch to the next node when it encounters a connection failure, which is much more convenient than manual processing.

Self-inspection checklist for avoiding pitfalls

- Don't use data center IPs (too distinctive)
- Don't request more often than the API limit of 80%.
- Higher success rate for collection from 1-5 am (UTC time)
- Regularly clear local cookies and cache
Don't panic when you encounter a 403 error code, first use ipipgo'sIP Detection ToolCheck to see if the current IP is flagged and change the city node to get full blood.

White QA First Aid Kit

Q: Do I have to use a paid proxy? Not the free ones?
A: 9 out of 10 free proxies are blacklisted IPs, and the remaining 1 will drop out at any time. ipipgo newcomers have3-Day Free Trial, just experience the gap for yourself.

Q: What should I do if the data returned by the API is incomplete?
A: Eighty percent triggered the flow limiting mechanism. Add aThe index is retreating for a retestLogic, in conjunction with ipipgo's 5G proxy package, basically picks up 99% of public data.

Q: Is the collected data commercially available?
A: Be careful! Coursera's terms and conditions explicitly prohibitcommercial use, doing academic research remember to anonymize the data and don't directly expose sensitive fields like course IDs.

To be perfectly honest, getting data collection is now acat and mouse gameI'm not sure if you're a fan of ipipgo. The last time I helped build an environment for a college lab, I used ipipgo'sHybrid Agent Program(Residential IP + server room IP rotation) and ran stable for three months without flipping.
