how to create twitter style API url..

[eluser]Unknown[/eluser]
Hello,

I want to share how to create Twitter style API url.

twitter using API Url like this :

Code:

http://search.twitter.com/search.json?callback=foo&q=twitter

now we create this configuration
in application/config.php :

Code:

$config['uri_protocol']         = "PATH_INFO";
$config['enable_query_strings'] = TRUE;
$config['controller_trigger']   = 'cxx';
$config['function_trigger']     = 'mxx';
$config['directory_trigger']    = 'dxx'; // experimental not currently in use

because i only need 1 controller using this, then i create this in my application/route.php

Code:

// Weather Services
$route['weather.json(.*)']   = "welcome/weather/json$1";
$route['weather.xml(.*)']    = "welcome/weather/xml$1";

// Location Based on CellID
$route['loc.json(.*)']       = "welcome/loc/json$1";
$route['loc.xml(.*)']        = "welcome/loc/xml$1";

then, in my controller as usually, i create function weather and loc like this :

Code:

function weather($type) {
    ..... rest of code .....

    switch($type) {
        case 'xml':
             $this->_outputXML();
             break;
        case 'json':
             $this->_outputJSON();
             break;
        default:
             $this->_error();
    }
}
function loc($type) {
    ..... rest of code .....

    switch($type) {
        case 'xml':
             $this->_outputXML();
             break;
        case 'json':
             $this->_outputJSON();
             break;
        default:
             $this->_error();
    }
}

and you can call the url http://your.server.url/weather.json?param and http://your.server.url/loc.json?param

that's it..

thanks
