Automating Weibo Login, Posting, and Liking with Python Requests

This article explains how to automate Weibo operations—login, posting a status, and liking posts—using Python's requests library. It first shows how to capture the login request in the browser, replicate the necessary headers (user‑agent, referer, cookie) and POST data, and then perform the login via code.

Next, it describes how to obtain the dynamic st token required for posting by requesting the /api/config endpoint, extracting the token from the JSON response, and sending a POST request to https://m.weibo.cn/api/statuses/update with the status content and the token.

Finally, the guide provides a class‑based implementation that logs in, retrieves the st token, fetches a list of the user's Weibo posts via https://m.weibo.cn/api/container/getIndex , and iterates over the posts (card_type 9) to send a like request to https://m.weibo.cn/api/attitudes/create using the post ID and the token.

Throughout the article, the author notes that cookies are not permanent and must be refreshed when login fails, and that the referer , origin , and host headers are often required to bypass anti‑scraping measures.

Full code snippets are provided for each step, including a simple script, a more structured class version, and a batch‑like function that likes all retrieved posts.
