Publishing to Juejin Through Its Web API: The mark_content Lesson
Automating content publishing is a common task for developer-advocates and technical writers. Juejin (掘金) is a popular Chinese developer community, and like many modern web apps, it relies on an internal HTTP API for its editor. That API is undocumented and changes without notice.

Juejin, a popular Chinese developer community, utilizes an internal HTTP API for its editor. This API is undocumented and changes without notice. A developer encountered a regression where drafts were saved with empty bodies and a publish call returning err_no=1010. The issue was traced to a required field named mark_content. By capturing the real client's actions through DevTools and generating cURL requests, the issue was identified.
The save draft call required mark_content to be present and non-empty. The publish call returned an error if mark_content was missing or empty. This information was then used to create Python functions for saving and publishing drafts using the requests library.
