AWS support part of the Jabber protocol. At this stage only two kind of messages are supported:
To check the presence status of a specific JID (Jabber ID)
To send messages to a specific JID (Jabber ID)
Note that if you want an application to check the presence or send message to users it is recommended to create a specific Jabber ID on the server for this application and ask users to accept this specific user to check their presence status.
9.1. Jabber presence¶
To check for the presence of another JID you must first have the right to do so. The jabber server won’t let you see presence of another JID unless the JID have permitted you to see its presence.
First declare the server and status objects:
Server : AWS.Jabber.Server; Status : AWS.Jabber.Presence_Status;
Connect to the server, you must have an account created and must know the login and password:
AWS.Jabber.Connect (Server, "jabber.domain.org", "joe", "mysuperpwd");
Then, to check the presence of user “john”:
AWS.Jabber.Check_Presence (Server, "email@example.com", Status);
Then, you just have to close the server:
9.2. Jabber message¶
To send a message to a specific JID, you must connect to the server as above and close the server when you don’t need to communicate with it anymore. The only different part is to send the message, here is an example:
Send_Message (Server, JID => "firstname.lastname@example.org", Subject => "Hello there!", Content => "Are you using AWS ?");
