nodeweb

a simple node web library

how to use

first

npm i wee-node --save-dev

second

  server.js
    const wee = require('wee-node') 
    const app = wee()
    app.use('/',function(req,res){
        res.send('hello,world');
    });
    app.listen(8080)

api

app.use(router,callback,callback)

  exzample server.js
    app.use('/',function(res,req){  
        res.write('hello!');  
        res.end();
    })

或者

    app.use('/',function(res,req){    
            res.write('hello!');  
            res.end();
        },  
    function(res,req,next){     
        //进入路由的生命周期,before  
        console.log('hello')   
        next();
    })
  
    res被添加两个静态方法
    res.send => res.write + res.end
    res.json => 发送json格式的字符串
    req被添加两个静态属性
    req.query=> ?demo=0    ==>  {demo:0}
    req.post=> post的body体。

app.static(realDictory,renamedictory)

app.static('./static');

  localhost:8080/static/index.html  

app.static('./static','img')

  localhost:8080/img/one.png

app.engine(engine)

  exzample server.js
   const laytpl = require('laytpl').__express;
   app.engine(laytpl);
   var options = {name:'hello,wee'}
   app.use('/',function(req,res){
        res.render('./index.html',options,function(err,str){
        res.send(str)     
   })
   })
  index.html
    <html>
    <head>
        <title></title>
    </head>
    <body>
    {{d.name}}
    </body>
    </html>     
    
  result
    hello,wee

app.staticnot(callback)

app.listen(port,protocol)

app.listen(8080,'http');

开启端口为8080的服务器,第二个参数默认是 http协议 ,暂时只支持,http,和https

app.chdir(dictory)

app.before(callback)

  exzample server.js
    app.before(function(req,res,next){  
        req.send('hello');
        next();
    })  

在所有请求到来后首先触发这个,需要用next去继续下面的路由行为

tool

wee-file-parse

use

    const app = require('wee-node')();
    const file = require('wee-file-parse');
    const fs = require('fs');
    app.use('upload',function(req,res){
        var chunks = [];
        req.on('data',function(chunk){
            chunks.push(chunk);
        });
        req.on('end',function(){
            var data = file(chunks);
            fs.writeFile('/'+data.filename,data,(err)=>{
                if(err){
                    throw err;
                }
                console.log('The file has been saved!');
            })
        })
    })

当将收集到上传的chunks传入到解析tool里面,会返回一个对象,该对象有两个属性,一个是上传的文件的body,一个是上传的文件的name
