if you are asking why, you can look at this question. https://codeshelper.com/q/10.

and if you ask how to do it, just use pdf.js . The principle is to retrieve and parse the data through fetch , convert the text to text, and use blob to generate the picture

.

this type of download file interface is in the form of stream file stream returned directly to the browser. When the browser receives a resource in the form of stream, it will only download it and cannot be previewed.
