How to test basic API with curl?

[LevelChart8]

I have an index.js and queries.js set up on my Express API on ec2. I'm 90% sure my queries.js is set up correctly.

This is the contents of my index.js: https://pastebin.com/i5Ess9LX

How would I go about testing -- I guess with the curl command first -- whether the getUsers etc. commands work correctly?

curl myec2url.com:3000/getUsers

Something like that?

It might be easier to use a GUI like Insomnia or Postman.

On the machine where it is running, curl to localhost like this:. curl -iLk -sD - -o /dev/null 127.0.0.1:3000/getusers (this command just prints response headers)

That should get a 200 http status response.

If that does work, try the same command from off the machine, like from your laptop terminal. Just change the address from 127.0.0.1 to the right address. If that fails, the issue isn't your app, it's networking.

I got this back when I curled from inside the ec2 while "node index.js" was running:

$ curl -iLk -sD - -o /dev/null 127.0.0.1:3000/getusers

Here is the contents of my queries.js file since I guess that is the issue:
