一、安装DNode
1， for nodejs， 执行
$ sudo npm install dnode
2, for php, 利用composer来安装DNode php
执行下列语句下载composer
$ wget http://getcomposer.org/composer.phar
创建一个文件composer.json，然后填入如下语句，
{
"require": {
"dnode/dnode": "0.2.0"
}
}
执行如下语句安装，
$ sudo php composer.phar install
二、利用nodejs创建简单server程序， server.js
var dnode = require('dnode');
var server = dnode({
zing: function (n, cb) { cb(n * 100) }
});
server.listen(7070);
三、利用php创建客户端程序client.php, 其中需要引用刚才安装的dnode文件夹里面的文件autoload.php
<?php
// Connect to DNode server running in port 7070 and call
// Zing with argument 33
require 'lib/vendor/autoload.php';
// This is the class we're exposing to DNode
class Temp
{
// Compute the client's temperature and stuff that value into the callback
public function temperature($cb)
{
}
}
$loop = new React/EventLoop/StreamSelectLoop();
$dnode = new DNode/DNode($loop, new Temp());
$dnode->connect(7070, function($remote, $connection) {
// Remote is a proxy object that provides us all methods
// from the server
$remote->zing(33, function($n) use ($connection) {
echo "n = {$n}/n";
// Once we have the result we can close the connection
$connection->end();
});
});
$loop->run();
?>
四、执行服务器端
$ node server.js
五、执行客户端调用服务端程序
$ php client.php
这会调用服务器端的加法程序，然后输出结果
n = 3300
