echo-post

POST parameter echo example

To try this example, you need GNU make and git in your PATH.

If you don’t have HTTPie installed, use the appropriate cURL commands instead.

Building

To build the example, run the following command:

make

Starting

Release

To start the release in the foreground:

./_rel/echo-post-example/bin/echo-post-example console

Note: The previous command also starts an Erlang console.

LFE

To start the app and an LFE shell:

lfe -pa ebin -pa deps/*/ebin -s echo-post # make dev

Usage

As this example echoes a POST parameter, it is a little more complex to test. Some browsers feature tools that allow you to perform one such request, or you can use the command line tool `http` as we will demonstrate.
