Difference between Content-Disposition: Form-data and attachment

I am building out an apache HttpClient for a REST service I have, and a app that will be using my service is sending a POST request using "content-disposition: attachment; name="file"; filename="file.txt".

Currently my Client is using "Content-Disposition: form-data; name="file"; filename="test.txt". Currently my request is multipart/mixed, where I am sending a file, and JSON.

Ideally I would need to have my client using the attachment one, but after much research, I have not found anything meaningful. What exactly is the difference between the two content-dispositions?

Solution

  • Attachment is for responses, form-data is for requests. https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Disposition
