Node.js中，q可以方便地将回调大坑转换成链式调用，极大地增强了代码的可读性，下面一段代码演示了q在链式调用和异步调用中起到的作用。源码//app.jsvar Q = require('q');function func1(){ console.log('fun1 start'); var deferred = Q.defer(); deferred.resolve('func1

Node.js代码var express = require('express');var app = express();var http = require('http');var server = http.createServer(app);app.set('trust proxy', true);// 设置以后，req.ips是ip数组；如果未经过代理，则为[]. 若不设置，则req

'use strict';var cluster = require('cluster');var numCPUs = require('os').cpus().length;// 每个fork出来的子进程, 都会从头执行该js文件console.log('Begin to run js file. pid = ' + process.pid);if(cluster.isMaster){ c

const TEMPLATE_NTH_OCCURANCE = '(?:(?:[^d]+d){n_1,}?)((?:[^d]+d){0,ps})';// !!!使用之前，务必bind({pageSize: xxx<integer>, pageNo: xxx<integer>})!!!function truncate(str, delimiterChar){ var pageSize = Ma

nock 可以拦截nodejs向外发送的HTTP请求，并模拟HTTP服务器响应，返回特定的结果，这对于接口测试非常方便。// 例子更改自: // https://github.com/node-nock/nock#use// 和// https://github.com/node-nock/nock#repeat-response-n-timesvar nock = require('nock

var Q = require('q');function _o(msg){console.log(msg);}function main(){ var obj1 = { var1: 1, func1: function(callback){_o('obj1.func1, var1 = ' + this.var1); callback(null, this.var1);} }
