Parameters with x-www-form-urlencoded are not included in the curl commandline and are not sent about loopback-component-explorer

I see. Can we get a sample app reproducing the problem please, so that we stop guessing? See https://github.com/strongloop/loopback/wiki/Reporting-issues#bug-report

I'm running into the same issue for API explorer at loopbackio/loopback-datasource-juggler@a65504b for PUT requests using source: 'form' for remoting.

There is no "-d" option in the curl command and I get the response with message "The 'MyInterface' instance is not valid. Details: 'name' can't be blank (value: undefined); 'url' can't be blank (value: undefined).", which I believe is caused by not sending the posted form data.

This makes perfect sense to me. Because your client send an empty request body, the server rejected the request with a validation error.

The solution is to add (possibly multiple) -d options to curl:

curl -X POST --header "Content-Type: application/x-www-form-urlencoded" \
  --header "Accept: application/json" \
  -d name=Login%20Preparation -d url=%2Flogin \
  "http://127.0.0.1:3000/api/MyInterfaces"

@fs523577192 I may be misunderstanding your bug report. What are you trying to accomplish? What behaviour did you expect from LoopBack?

@bajtos I believe he is talking about the curl line that shows up in API explorer. I ran into the same issue when issueing PUT with form. I expected the curl output from the UI to show -F or -d for JSON, but it simply shows no -d or -F flag and sends no data with the request.
