Purpose:

Forward several types of messages as post requests to an arbitrary url.

mod_offline_post forwards messages that are sent to offline users through a post request to a configurable url mod_available_post sends a post request with information about a user that has become available mod_unavailable_post sends a post request with information about a user that has gone offline

Note:

Between ejabberd 2.1.13 and 13.10 there were significant changes and modules compiled for one version don't directly work with the other version. There is an ejabberd_2.1.13 branch for versions of these modules that work with ejabberd 2.1.13

Installing:

• Make sure you have erlang installed on the machine you are building from
  • You probably want this to be the same machine you intend to install/run ejabberd on. I'm not sure about the interoperability of ejabberd/erlang versions.
• Open the Emakefile and change /usr/local/Cellar/ejabberd/2.1.10/lib/ejabberd/include to the correct path on your machine
• Run the build.sh script to build *.beam files
• Copy the *.beam files from the ebin directory to the location where the other modules are for your server
• Add the configuration shown below to your ejabberd.cfg file, providing the correct values for auth_token, and post_url

Example Configuration:

	% configuration for ejabberd upto version 13.10
	{mod_offline_post, [
		{auth_token, "offline_post_auth_token"},
		{post_url, "http://localhost:4567/offline_post"}
	]}
	{mod_available_post, [
		{auth_token, "mod_available_post"},
		{post_url, "http://localhost:4567/available_post"}
	]}
	{mod_unavailable_post, [
		{auth_token, "unavailable_post_auth_token"},
		{post_url, "http://localhost:4567/unavailable_post"}
	]}

# configuration for ejabberd >= 13.10
	mod_offline_post:
		auth_token: "offline_post_auth_token"
		post_url: "http://localhost:4567/offline_post"

	mod_available_post:
		auth_token: "available_post_auth_token"
		post_url: "http://localhost:4567/available_post"

	mod_unavailable_post:
		auth_token: "unavailable_post_auth_token"
		post_url: "http://localhost:4567/unavailable_post"

Results:

The application running at the post_url will receive a post http request with the following form parameters.

	mod_offline_post
	"to"=>"adam2@localhost"
	"from"=>"adam1"
	"body"=>"Does it still work?"
	"access_token"=>"offline_post_auth_token"

	mod_available_post
	"jabber_id"=>"adam2"
	"access_token"=>"mod_available_post"

	mod_unavailable_post
	"jabber_id"=>"adam2"
	"access_token"=>"unavailable_post_auth_token"
