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 ReactEventLoopStreamSelectLoop(); $dnode = new DNodeDNode($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
