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,weeapp.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
data.file
data.filename
