Hi everyone,
I'm going to develop this service: I use CakePHP Framework to develop a web application (consider this address for it: http://news.webapp.it) that allow clients to request news from social networks. I used social API (Facebook, twitter, Google+) to send a request to know what client wants. It's simple and runs correctly. Each tweet or fb post that I receive can have a link and I use it to request a parsing of the webpage linked, making an AJAX request for each link to my server that will do CURL connection towards the external websites (I use readability lib).
The problem is in this step: once loaded tweets/posts, I send several ajax request to my server, denying any other action that involves communication with server (Ajax again, for example - new requests go obviously into a queue).
So, I think that a solution for my problem is to adopt a NodeJS server (that I can test at this url http://news.webapp.it/nodejs - because I made a folder in CakePHP root, named Nodejs, and customize .htaccess file for this) to make those several request for parsing pages, leaving free the direct channel with the server for other possible requests from client. But I cannot find a solution to do a communication between a CakePHP View script (Javascript) and NodeJS server. I tried this
CakePHP Client-Side : index.ctp
<input type="button" value="Get AUTH" class="first" />
<p class="codeAuth">CODE for auth: </p>
<p class="result"></p>
<script>
$(document).ready(function() {
$('.first').click( function(){
$.getJSON("http://192.aaa.bbb.ccc:8077/&callback=?",
function(data){
console.log('Done with success!');
},
function(jqXHR, textStatus, errorThrown) {
console.log('error ' + textStatus + " " + errorThrown);
});
});
});
</script>
NodeJS Server-Side: server.js
var http = require('http');
var querystring = require('querystring');
var url = require('url');
var sys = require('sys');
http.createServer(function (req, res) {
var pquery = querystring.parse(url.parse(req.url).query);
sys.puts("PQUERY: "+pquery);
var callback = (pquery.callback ? pquery.callback : '');
sys.puts("Callback: "+ callback);
var returnObject = {message: "Hello World!"};
var returnObjectString = JSON.stringify(returnObject);
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end(callback + '(\'' + returnObjectString + '\')');
}).listen(8077, '192.aaa.bbb.ccc');
sys.puts("Server running at http://192.aaa.bbb.ccc");
This javascript client side code doesn't work but the server starts correctly and if I try http://news.webapp.it/nodejs in the browser address field, it return the message "Hello World".
I hope that I have explained my problem.
Is there anyone that can I help me?
