javascript - How to save files uploaded by the front end in nodejs

Question

For example, my front-end

<form method="post" action="/on_data">
<input type="file" name="valuename" enctype="multipart/form-data" multiple="multiple" > ;

<button>tijiao</button>

</form>

So how does the backend receive this picture? I found a lot of examples, and basically all of them used various frameworks (maybe I didn’t describe it clearly, but I couldn’t find the native ones anyway).

Answer 1

Plug-in implementation node-formidable

Native implementation link

Answer 2

The plug-in uses multer
