概念:Javascript运行时平台,不是语言,也不是框架,是一个平台。javascript
Hello.jscss
1.编写js文件html
2.定位到目录vue
3.输入node xxx.js,解释执行java
let str="hello world"console.log(str)console.log(window) //没有bomconsole.log(document) //没有dom12345
多出来的功能:node
//1.定义导入包 let fs=require('fs') //2.读取hello.js //参数:路径,匿名函数 fs.readFile('hello.js',function (error,data) { console.log(data);//utf-8编码 console.log(data.toString()); //格式能够输出 })12345678
输出的格式不是ASCI编码格式,注意!!!python
关于参数的代码理解android
//1.定义导入包let fs=require('fs')//2.读取hello.js//参数:路径,匿名函数fs.readFile('hello2.js',function (error,data) { // if(error==null) // console.log('没有错误') if(error) console.log('读取文件失败!') else console.log(data.toString());})123456789101112
//1.导入http包let http=require('http')//2.定义server变量,返回一个server实例;let server=http.createServer()//3.服务器的响应,接受request请求,产生会回调事件server.on('request',function () { console.log('接受来自客户端的请求....')})//4.绑定到响应的端口号;server.listen(3000,function () { console.log('服务器启动了,能够经过http://localhost:3000/来访问...')})123456789101112
//1.导入http包let http=require('http')//2.定义server变量,返回一个server实例;let server=http.createServer()//3.服务器的响应,接受request请求,产生会回调事件//增长参数:request、responseserver.on('request',function (request,response) { console.log('接受来自客户端的请求....') console.log('请求路径是:'+request.url) //response:响应输出;服务器发送给客户端 response.write('你好') response.write('test...aaa') response.end()})//4.绑定到响应的端口号;server.listen(3000,function () { console.log('服务器启动了,能够经过http://localhost:3000/来访问...')})123456789101112131415161718
根据不一样的url返回不一样的服务git
let url=request.urlgithub
url返回的是/以后的路径
//1.导入http包let http=require('http')//2.定义server变量,返回一个server实例;let server=http.createServer()//3.服务器的响应,接受request请求,产生会回调事件//增长参数:request、responseserver.on('request',function (request,response) { console.log('接受来自客户端的请求....') console.log('请求路径是:'+request.url) //3.1获取请求的url路径信息; let url=request.url console.log('----'+url) //接下来,根据url进行判断; if(url=='/'){ response.end('index.html') }else if(url=='/login'){ response.end('login.html') }else if(url=='/products'){ let products=[ {name:'苹果',price:4.5}, {name:'香蕉',price:3.5}, {name:'橘子',price:2.5}] response.end(JSON.stringify(products)) } else{ response.end('404 Error') } //response:响应输出;服务器发送给客户端 // response.write('你好') // response.write('test...aaa') // response.end()})//4.绑定到响应的端口号;server.listen(3000,function () { console.log('服务器启动了,能够经过http://localhost:3000/来访问...')})123456789101112131415161718192021222324252627282930313233343536
模块分为三种:
以前代码require(‘fs’)就是引用的内置模块。Node为JS提供了不少服务器级别的API,这些API绝大多数都被包装到了一个有名字的核心模块。例如文件操做的fs模块。
使用格式:
let 变量名=require(‘模块名’) //fs:文件读写模块
let http=require(‘http’) //http:协议模块;
let path=require(‘path’) //路径处理模块
let os=require(‘os’)
let fs=require(‘fs’)
let fs = require("fs");//建立文件夹//fs.mkdir('./hello',(err,data)=>{// console.log(err);// console.log(data);//});//修改文件夹//fs.rename('./hello','./testyyh',(err)=>{// if(err){// console.log("error");// }else{// console.log("ok");// }//});//删除文件夹-->只能删除空文件夹fs.rmdir('./testyyh',(err)=>{ if(err){ console.log('删除失败'); console.log(err); }else{ console.log('ok'); }1234567891011121314151617181920212223
const fs = require('fs');//建立文件,覆盖写入,正常的话则是追加//fs.writeFile('test.txt','这是个人第一个文件',(err)=>{// if(err){// console.log('建立失败');// console.log(err);// }else{// // console.log('建立成功!');// }// //});//读取文件,在原来的基础上追加文件//fs.appendFile('test.txt','韩梅梅你好',(err)=>{// console.log(err);//});//读取文件这是第一种方式//fs.readFile('test.txt',(err,msg)=>{// console.log(err);// console.log(msg.toString("utf8"));//在转化为字符串的时候指定编码方式//});//在参数中指定编码方式//fs.readFile('test.txt','utf8',(err,msg)=>{// // console.log(err);// console.log(msg);//});//删除文件//fs.unlink('./test.txt',(err)=>{// console.log(err);//});1234567891011121314151617181920212223242526272829303132
const fs = require('fs');fs.readdir('./',(err,dirs)=>{ for(let index=0;index<dirs.length;index++){ console.log(dirs[index]); }});fs.stat('./',(err,stats)=>{ if(stats.isFile()){ console.log('是一个文件'); }else{ console.log('是一个目录'); }});1234567891011121314
详细介绍自定义模块:
建立一个模块(一个js文件就是一个模块),这是test.js
let hellomodule={ sayhell(){ console.log("hello world"); }}module.exports=hellomodule123456
在另一个文件进行调用
//1.导入文件;必须是./的模式,直接路径不可用;let testModule=require('./module.js')//2.直接使用;console.log(testModule)testModule.sayhell()12345
//1.引用os核心模块let os=require('os')//2.输出cpu的信息;console.log(os.cpus())//内存信息console.log(os.totalmem())console.log(os.type)//.1.1引用path核心模块let path=require('path')//2.测试path;path.extname('c:/soft/oop.java')//ext:扩展名console.log(path.extname('c:/soft/oop.java'))123456789101112131415
//输出端口号;console.log('请求端口号:'+request.socket.remotePort)console.log('请求地址:'+request.socket.remoteAddress)123
let http=require('http')let server=http.createServer()server.on('request',(req,resp)=>{ console.log('请求地址:'+req.url) console.log('请求客户端地址信息:'+req.socket.remotePort,req.socket.remoteAddress) resp.end('hello world.张晨光...')})server.listen(5000,()=>{ console.log('服务器启动能够访问了...')})1234567891011121314
能够启动多个服务,端口号不一样就行!!!
let http=require('http')let fs=require('fs')let server=http.createServer()server.on('request',(req,resp)=>{ let url=req.url if(url==='/'){ fs.readFile('./hello.html',(err,data)=>{ if(err){ resp.setHeader('Content-Type','text/plain;charset=utf-8') resp.end('文件读取失败!') }else{ resp.setHeader('Content-Type','text/html;charset=utf-8') resp.end(data) } }) }})server.listen(3000,()=>{ console.log('服务器启动能够访问了...')})1234567891011121314151617181920212223
能够读取图片的程序升级
let http=require('http')let fs=require('fs')let server=http.createServer()server.on('request',(req,resp)=>{ let url=req.url if(url==='/'){ fs.readFile('./hello.html',(err,data)=>{ if(err){ resp.setHeader('Content-Type','text/plain;charset=utf-8') resp.end('文件读取失败!') }else{ resp.setHeader('Content-Type','text/html;charset=utf-8') resp.end(data) } }) } else if(url==='/photo'){ fs.readFile('./resources/2a.jpg',(err,data)=>{ if(err){ resp.setHeader('Content-Type','text/plain;charset=utf-8') resp.end('图片读取失败!') }else{ resp.setHeader('Content-Type','image/jpeg') resp.end(data) } }) }})server.listen(3000,()=>{ console.log('服务器启动能够访问了...')})12345678910111213141516171819202122232425262728293031323334

必须经过npm 安装
文件做用域
通讯规则
模块做用域
使用require来加载模块
语法:var|let 变量名=require(‘模块’)
做用:执行被加载模块中的代码;获得被加载模块中的exports导出接口对象
使用exports接口对象来导出模块中的成员
node是模块做用域,全部成员再当前模块有效;
module.exports=‘字符串’
module.exports=function(){}
后面会覆盖前面的值;
注意:exports是module.exports的一个引用,不能直接赋值。
//路径形式的模块// ./// ../// /xxx 通常不用// / 标识当前模块系统所属的磁盘根路径// .js 后缀名能够省略// require(./foo.js)//核心模块实际上也是文件,核心模块文件已经编译到node.exe了//github.com-->node查看源码能够看到fs.js os.js//https://github.com/nodejs/node//https://github.com/nodejs/node/tree/master/lib//第三方模块:本质上也是文件,须要经过npm下载,使用的时候仍然经过require('包名')来加载使用//不可能由任何一个第三方模块和核心模块文件名一致//既不是核心模块,也不是核心路径的模块,先找到node-modules目录,其次找其中的art-template// node_modules/art-template// node_modules/art-template/package.json文件// node_modules/art-template/package.json中的main属性// main属性中记录了art-template的入口模块,加载第三方包(包名),实际最终加载的仍是文件// 模拟实现// let template=require('art-template')// 模拟一下require('a')123456789101112131415161718192021222324252627
测试第三方模块,在node_modules下新建一个a目录,建立package.json的文件
{ "main":"foo.js"}123
foo.js
console.log('a中的foo.js被加载了...')module.exports=()=>{ console.log('fooooooo....')}12345
//若是package.json不存在或者main指定的入口模块也没有,则node会自动查找该目录下的index.js//即index.js会做为一个默认备选项。若是上述条件不成立,则去上级目录去寻找node_modules的目录,没有继续往//上级寻找,在a目录下建立index.jsconsole.log('a--->index')1234
若是继续往上一级查找node_modules,尚未找到,则显示:
Error: Cannot find module ‘vue’
注意:咱们的一个项目有且只有一个node_modules,这样项目均可以加载到第三方模块包,不会出现多个。
apache软件默认有一个www目录,此目录下的html文件均可以经过node。案例模拟实现apache项目在浏览器的效果。
读取node下的www目录文件的代码
let http=require('http')let fs=require('fs')//2.开始设置服务;let server=http.createServer()server.on('request',(req,resp)=>{ let url=req.url //若是是这个方式的话,去某个地方 /* * / index.html * /a.txt +/a.txt * /mi/login.html * /img/bg.jpg wwwdir+/img/bg.jpg * */ let wwwDir='D:/aaa/node/www' let filePath='/index.html' if(url!=='/'){ filePath=url } console.log(wwwDir+filePath) fs.readFile(wwwDir+filePath,(err,data)=>{ if(err){ console.log('404 Not Found!') } resp.end(data) })})//3.绑定机制;server.listen(3000,()=>{ console.log('启动了...')})1234567891011121314151617181920212223242526272829303132
模板引擎不关心内容,只关心本身能认识的模板标记语法。Mustache是一个logic-less(轻逻辑)模板解析引擎,
它是为了使用户界面与业务数据(内容)分离而产生的,
它能够生成特定格式的文档,一般是标准的HTML文档。
好比小程序的wxml中的代码
{{userInfo.nickName}},这里的{{ }}就是Mustache的语法。1
art-template 是一个简约、超快的模板引擎。
它采用做用域预声明的技术来优化模板渲染速度,从而得到接近 JavaScript 极限的运行性能,而且同时支持 NodeJS 和浏览器。
art-template 同时支持两种模板语法。标准语法可让模板更容易读写;原始语法具备强大的逻辑处理能力。
{{if user}}<h2>{{user.name}}</h2>{{/if}}123
<% if (user) { %><h2><%= user.name %></h2><% } %>123
使用步骤:
1.安装
npm install art-template
2.在须要使用的文件中加载art-template
let temp=require(‘art-template’)
3.查文档,使用art-template的API
在node-modules下的模板文件
<!DOCTYPE html><html style="height: 100%"><head> <meta charset="utf-8"> <!--<title>{{ title }}</title>--> <title><%=title%></title></head><body> <script src="../node_modules/art-template/lib/template-web.js"></script> <script type="text/template" id="tp1"> hello{{name}} 年龄:{{age}} 地址:{{address}} 爱好:{{each hobbies}}{{$value}}{{/each}} </script><!--测试--> <script> var ret=template('tp1',{name:'jack ma', age:22, address:'河南省郑州市', hobbies:['吃好饭','唱好歌','开好车'] }) console.log(ret) </script></body></html>123456789101112131415161718192021222324252627
node.js使用art-template
let template=require('art-template')//template('script标签id',{对象})let result=template.render('Hello:{{name}}',{name:'张晨光'})console.log(result)12345678
结合模板来使用
let template=require('art-template')let tempstr=`<!DOCTYPE html> <html style="height: 100%"> <head> <meta charset="utf-8"> <title><%=title%></title> </head> <body> hello{{name}} 年龄:{{age}} 地址:{{address}} 爱好:{{each hobbies}}{{$value}}{{/each}} </body> </html>`//template('script标签id',{对象})let result=template.render(tempstr,{name:'jack ma', age:22, address:'河南省郑州市', hobbies:['吃好饭','唱好歌','开好车']})console.log(result)123456789101112131415161718192021222324
