1.3、NodeJS中使用CommonJS模块管理 CommonJS的核心思想就是通过 require 方法来同步加载所要依赖的其他模块,然后通过 exports 或者 module.exports 来导出需要暴露的接口。 CommonJSAPI编写应用程序,然后这些应用可以运行在不同的JavaScript解释器和不同的主机环境中。 2009年,美国程序员Ryan Dahl创造了node.js项目,将ja...

The Node.js app is defined in the fileserver.js, located in the directory for the web role (WebRole1by default). Here's the code: JavaScript varhttp =require('http');varport = process.env.port ||1337; http.createServer(function(req, res){ res.writeHead(200, {'Content-Type':'text/...

我们看到nodejs首先调用connect绑定服务器的地址,然后调用send发送信息,最后调用close。我们一个个分析。首先看connect。 代码语言:javascript 复制 Socket.prototype.connect = function(port, address, callback) { port = validatePort(port); // 参数处理 if (typeof address === 'function') { callback = ad...
