In-band registration: How do I connect to the network to register new users?

drayarms · #1 (**permalink**) April 3rd, 2014, 12:31 PM

Hello once again coders, anyone familiar with in-band registration? I just found out about it and decided it was the best way to hook up my app users with jabber ids, without having them go through the headache of obtaining one themselves. Since I'm new to it, this may sound as a silly question. In order to send stanzas to an XMPP server, you need to be connected through an XMPP account right? So I login with my jid to Jack's beautifully created peek console and send the following stanza to the server

Code:

$iq({type: "get", id: "reg1"}).c("query", {xmlns:"jabber:iq:register"})

which is supposed to get the register fields. The server sends back the following stanza

Code:

<iq id='reg1'
    type='result'
    to='my_jid@miqote.com/my_resource'>
<query xmlns='jabber:iq:register'>
<registered/>
<username>
my_jid
</username>
<password/>
</query>
</iq>

Note that I replaced my real jid with "my_jid"
So the puzzle is, how in the world am I supposed to register a new user if the server recognizes that my stanza is coming from an already registered user? Or is it possible to somehow send stanzas to the server without loging in with an already existing username?

This is not possible without the use of plugins. See the plugins at https://github.com/strophe/strophejs-plugins

The issue is that normally Strophe establishes an authenticated or anonymous session, and the legacy registration protocol must be done before a session is established.

I'll take a look at that Jack. Thanks for the lead.

I uploaded strophe.register.js from github to my server. Then I ran the register plugin. My final code looks like this(I'm including the html for clarity)

};

var connection = new Strophe.Connection("http://bosh.metajack.im:5280/xmpp-httpbind");

connection.register.connect("miqote.com", callback, wait, hold);

});//End click

<div data-role = "content" style = "border:1px dotted blue;position:relative;top:20%;left:20%;width:400p x;height:300px">

</html>

When I fill in the username and password fields(only these two are allowed by server), and hit "register", i get this error

"Uncaught TypeError: Cannot call method 'bind' of undefined strophe.register.js:85"

What am I missing?

Need to download code?
