Testing file uploading with curl

Today I spent some time adding user avatars to a NodeJS application. I’m using Formidable and Express to do it, but it’s finicky enough that I want to get the endpoint working before I start doing any forms.

If you want to upload an image with curl you can use

curl -d @avatar.jpg "http://localhost:3000/avatar/2"

but if you want to add some ancillary data, you’ll need something like;

curl -F "file=@a.jpg;type=image/jpg"-F "id=2" "http://localhost:3000/avatar/2"
