    php和NodeJs共存的开发环境

    什么?有这样的需求吗

    1 折腾 php nodejs 到一起

    nodejs当然很火,就像着火了一样,但是必须承认要搭建一个前端的demo开发环境还是PHP靠谱, windows下可以非常的集成套件,比如http://www.apachefriends.org/zhcn/xampp.html, PHP语言本身就是一个强大的模板,写demo时,共用头尾,可以通过include和require引入,可以内嵌 循环生成一些dom结构,相较而言,node还是不那么方便的。

    既然PHP已经那么方便了,可是为什么还是要跟node一起用呢,真的有点为了用而用了……

    2 how?

    如你安装了Python,可以立马执行一个简单的命令,一个简便的开发服务器就完成了。

    python -m SimpleHTTPServer
    

    但是PHP,直到php5.4才支持类似的功能

    $ php -S 0.0.0.0:8000
    PHP 5.4.0 Development Server started at Tue Aug 21 23:21:50 2012
    Listening on 0.0.0.0:8000
    Document root is /home/tom
    Press Ctrl-C to quit.
    

    php本身就可以架一个服务器,Nodejs也可以架一个服务器,那么就不用啥apache啦,nginx啦

    基本思路就是Node开启一个服务器作为前台,监听80端口,类似Apache的角色,php开启一个服务器在后台运行。 Node服务将http请求转发给php服务器执行,执行完成后返回给node服务器,node服务器再返回给浏览器

    Node承担的是一个中间的代理角色

    var fs = require('fs'),
        http = require('http'),
        spawn = require('child_process').spawn,
        phpserver;
    
    phpserver = spawn('php',['-S','0.0.0.0:8000']);
    phpserver.stdout.on('data', function (data) {
      console.log('stdout: ' + data);
    });
    phpserver.stderr.on('data', function (data) {
      console.log('stderr: ' + data);
    });
    phpserver.on('exit', function (code) {
      console.log('child process exited with code ' + code);
    });
    
    process.on('exit',function(){
      phpserver.kill('SIGHUP');
    });
    
    function handleRequest(request, response) {
      var headers = {};
    
      for(var x in request.headers){
        headers[x] = request.headers[x];
      }
    
      headers['Content-Type']= 'application/x-www-form-urlencoded';
    
      var proxy_request = http.request({
        host:'localhost',
        port:8000,
        method:request.method,
        path:request.url,
        headers:headers
      });
    
      proxy_request.on('response', function (proxy_response) {
        response.writeHead(proxy_response.statusCode,proxy_response.headers);
        proxy_response.on('data', function(chunk) {
          response.write(new Buffer(chunk));
        });
        proxy_response.on('end', function() {
          response.end();
        });
    
      });
    
      request.on('data', function(chunk) {
        proxy_request.write(new Buffer(chunk));
      });
    
      request.on('end', function() {
        proxy_request.end();
      });
    }
    http.createServer(handleRequest).listen(80);
    

    保存上面的文件为server.js然后在命令行里执行

    node server.js
    

    一个node和php混搭的服务器就搭建成功了

    3 注意点

     

    3.1 请求和响应数据须是Buffer对象

    response.write(new Buffer(chunk))
    proxy_request.write(new Buffer(chunk));
    

    3.2 要想传递表单数据,需要在header设置

    headers['Content-Type']= 'application/x-www-form-urlencoded';
