How to Automate CSDN Blog Comments with Python Requests & BeautifulSoup

Login to CSDN

Use the requests library to create a session, fetch the login page, and parse hidden fields such as lt and execution with BeautifulSoup. These values are required to construct a valid login POST request.

Submit a Comment

After logging in, locate the comment form on the target article page. Build the POST payload, ensuring the comment field is filled; otherwise the server returns

{"result":0,"content":"评论内容没有填写！","callback":null,"data":null}

. The script extracts the required action URL from the page.

Analyze comment.js

Inspect the JavaScript file comment.js to understand how the form is submitted. The subform method builds the final POST data, and the load_comment_form() function defines the action pattern as "/" + username + "/comment/submit?id=" + fileName. This reveals that only the article author name and file identifier are needed.

Run the Automation Script

Combine the extracted username and fileName to construct the comment submission URL, then send the POST request with the comment text. The script logs in, fetches the article, builds the payload, and posts the comment automatically. The comment appears in the management interface, confirming successful automation.
