HTML5 XMPP Client build in Ionic Cordova : PART 5

This is a follow up of my previous tutorial series on How to build ionic XMPP Chat client. Here we will be integrating chat client with online XMPP servers. We will also cover inband registration. So lets get started.

Free XMPP server used here is  jabberpl.org

What New:

1. Supports remote XMPP server.
2. In band Registration to remote XMPP server.
3. Better implementation for Chat Logs.

So lets get started.

Register Page:

First of all include strophe.register.js into your strophe’s library folder.

Now include this library inside index.html

	<!--Strophe Register -->
	http://lib/strophe/register/strophe.register.js

controller.js –>  registerCtrl

.controller('registerCtrl', function($scope , $state , sharedConn   ) { 
	
	$scope.goToLogin=function(){
		$state.go('login', {}, {location: "replace", reload: true});
	}
	$scope.reg=function(r){
		r.domain="jabberpl.org";  // you can comment it if you want
		sharedConn.register(r.jid,r.pass,r.domain);
	}

	
})

services.js –> SharedConn

	SharedConnObj.register=function (jid,pass,domain) {
		//to add register function
		SharedConnObj.connection = new Strophe.Connection("https://conversejs.org/http-bind/");

		var callback = function (status) {
			if (status === Strophe.Status.REGISTER) {
				// fill out the fields
				SharedConnObj.connection.register.fields.username = jid;
				SharedConnObj.connection.register.fields.password = pass;
				// calling submit will continue the registration process
				SharedConnObj.connection.register.submit();
			} else if (status === Strophe.Status.REGISTERED) {
				console.log("registered!");
				// calling login will authenticate the registered JID.
				SharedConnObj.connection.authenticate();
			} else if (status === Strophe.Status.CONFLICT) {
				console.log("Contact already existed!");
			} else if (status === Strophe.Status.NOTACCEPTABLE) {
				console.log("Registration form not properly filled out.")
			} else if (status === Strophe.Status.REGIFAIL) {
				console.log("The Server does not support In-Band Registration")
			} else if (status === Strophe.Status.CONNECTED) {
				// do something after successful authentication
				$state.go('tabsController.contacts', {}, {location: "replace", reload: true});
			} else {
				// Do other stuff
			}
		};
		
		SharedConnObj.connection.register.connect(domain, callback, 60, 1);		
	};

register.html

<ion-view style="" id="page7" title="Register" hide-back-button="true">
    <ion-content class="has-header" padding="true">
        <form style="" class="list">
            <ion-list style="">
			
                <label style="" class="item item-input">
                    <span class="input-label">Jabber ID</span>
                    <input ng-model="register.jid" placeholder="username" type="text">
                </label>
            
				<label style="" class="item item-input">
                    <span class="input-label">Password</span>
                    <input ng-model="register.pass" placeholder="password" type="password">
                </label>
                
				<label style="" class="item item-input">
                    <span class="input-label">Domain</span>
                    <input ng-model="register.domain" placeholder="jabberpl.org" type="text">
                </label>
            
			</ion-list>
            <div style="height: 40px;" class="spacer"></div>
            
			 <button  class="button button-stable button-block "  id="register-button" ng-click="reg(register)" >Register</button>
			
			 
			 <button  class="button button-stable button-block "  id="login-button" ng-click="goToLogin()" >Login</button>
			 
            
			</form>
    </ion-content>
</ion-view>

LOGIN

To handle login to a remote XMPP server, we need to get the corresponding BOSH_SERVICE_URL and PORT number. We can get the respective url and port number by setting BOSH_URL as https://conversejs.org/http-bind/

login.html

<ion-view style="" id="page5" title="Login" hide-back-button="true">
    <ion-content class="has-header" padding="true">
        <form style="" class="list">
            <ion-list style="">
			
                <label style="" class="item item-input">
                    <span class="input-label">Jabber ID</span>
                    <input ng-model="user.jid" placeholder="username" type="text">
                </label>
            
				<label style="" class="item item-input">
                    <span class="input-label">Password</span>
                    <input ng-model="user.pass" placeholder="password" type="password">
                </label>
                
				<label style="" class="item item-input">
                    <span class="input-label">Host</span>
                    <input ng-model="user.host" placeholder="jabberpl.org" type="text">
                </label>
            
			</ion-list>
            <div style="height: 40px;" class="spacer"></div>
            
			 <button  class="button button-stable button-block "  id="login-button" ng-click="login(user)" >Log in</button>
			 
			 <button  class="button button-stable button-block "  id="register-button" ng-click="goToRegister()" >Register</button>
            
			</form>
    </ion-content>
</ion-view>

control.js –> loginCtrl

.controller('loginCtrl', function($scope , sharedConn,$state ) {

	var XMPP_DOMAIN  = 'jabberpl.org'; // Domain we are going to be connected to.
	var xmpp_user    = 'username';     // xmpp user name
	var xmpp_pass    = 'password';
	
	$scope.goToRegister=function(){
		$state.go('register', {}, {location: "replace", reload: true});
	}
	
	
	//sharedConn.login(xmpp_user,XMPP_DOMAIN,xmpp_pass);  // To automate login
	
	$scope.login=function(user){
		sharedConn.login(user.jid,XMPP_DOMAIN,user.pass);
	}
	
})

service.js –> sharedConnService

SharedConnObj.BOSH_SERVICE = 'https://conversejs.org/http-bind/';

BETTER CHATLOGS:

Earlier we were only taking distinct jabber_id from the from_id column of chats to output in the chat-log. This was ineffective as you cannot get the jabber_id’s from to_id. I have modified the SQL to take distinct values from from_id and to_id.

//Better implementation 	
		var query = "SELECT logtable.logid FROM ( SELECT from_id as logid FROM chats UNION SELECT to_id as logid FROM chats )logtable where logid not like ? ";
		
        $cordovaSQLite.execute($rootScope.db, query,[my]).then(function(res) {
            if(res.rows.length > 0) {
				for (var i=0 ; i<res.rows.length; i=i+1) {
					sqlObj.chatlogs.push({
						id: res.rows.item(i).logid,
						name:  res.rows.item(i).logid,
						lastText: 'Last Text',
						face: 'img/ben.png'
					});
                }				
					
            } else {
                console.log("No results found");
            }
        }, function (err) {
            console.error(err);
		});

Now we are ready to go.

Please note that in order to run XMPP client with SQL, you need to use Chrome Web Browser. It supports WebSQL and your messages are stored in the Browsers local webSQL database.

You can also download my XMPP client without SQL to test it on other browser.
