Answer 1

You can use -d "" causes CURL to send a Content-Length: 0,

see Header 'Content-Length: 0' is missing when I do curl -X POST $URI

Answer 2

Try this: curl -X POST http://localhost:9090/pro/v1/files -d "Content-Length: 0"

curl's -d flag allows you to add data to the body of the request. According to its docs:

-d, --data (HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded.
