1. Column background

As an old user of CSDN, since CSDN emphasized the need to create a high-quality comment area, there is still room for improvement in the hot list comment area. Therefore, in this column, we will combine AI and explore some methods to improve the quality of the comment area.
This column is only the blogger’s idea and is used for technical learning and has nothing to do with the official website!

Let’s first get the data on the hot list.

This interface is unauthenticated. You can directly enter the uri in the browser search window to obtain the data: Hot list interface

3. Get comment area data

From the previous interface, it is easy to get. The productId returned by the interface is the ID of the article. The link to the article details page is https://blog.csdn.net/{userName}/article/details/{productId}.
Well, actually the articleDetailUrl field has the complete url address.

// 热榜数据接口部分字段

    "userName": "xxx",
    "articleDetailUrl": "https://blog.csdn.net/user_name/article/details/product_id",
