Is there an existing issue for this?

I have searched the existing issues

Current behavior

When using application/x-www-from-urlencoded to send form data, if you fill in duplicate key names, only the last key will be sent.

key	value
id	1
id	2

Should be encoded as id=1&id=2,
but is actually encoded as id=2.

Steps to reproduce

Enter test url
Choose Body
Change Content-Type to application/x-www-from-urlencoded
Fill in two values with the same key
Send,and you can see the wrong Body on the server

Environment

Release
