I'm trying to use the native Fetch and FormData APIs to upload multiple files at once to the server but I can't for the life of me get it to work.

Curl post with multipart/form-data and JSON

阅读更多关于 Curl post with multipart/form-data and JSON

Is there a way to use curl to do a multipart/form-data post and specify that the data is application/json ? It doesn't have to be curl.
