How I Sniffed Xiaohongshu's Collection API in 90 Seconds — and Why CORS Made Me Rewrite the Whole Approach

1. 1Use a browser automation tool like Playwright to render the Xiaohongshu web client
2. 2Configure the tool to listen for the API request and capture the response
3. 3Parse the response data to extract the user's saved-posts list
4. 4Apply CORS bypass techniques to handle cross-origin resource sharing restrictions
5. 5Test and refine the approach to ensure reliable data scraping

This approach benefits developers and engineers who need to scrape data from web clients with complex API request-signature schemes, particularly those working with web scraping, automation, or data analysis

💡 Letting the browser issue the request and listening for the response can be an effective way to bypass CORS and scrape data from web clients with complex API request-signature schemes
