express:
- 主體
- cookie、session
- 資料
- 模板引擎
body-parser 解析post資料 enctype="application/x-www-form-urlencoded"
server.use(bodyParser.urlencode());
req.body
multer 解析post檔案 enctype="multipart/form-data"
var obj=multer({dest:'upload/'});
server.use(obj.any());
server.use(functuon(req,res){
req.files[0].originalname;
req.files[0].path
})
把副檔名加上
//'upload/aksjdhakjhdsad'+'.txt'
//'upload/aksjdhakjhdsad.txt'
var newName=file.path+pathLib.parse(file.originalname).ext;
fs.rename

簡易上傳檔案伺服器
server_file.js
const express=require('express'); const bodyParser=require('body-parser'); const multer=require('multer'); const fs=require('fs'); //用其rename函式修改上傳上來的檔名字尾 const pathLib=require('path'); //獲取檔案路徑以及檔案字尾名 var objMulter=multer({dest:'./www/upload'}); var server=express(); //錯誤 //server.use(bodyParser.urlencoded({extended:false})); server.use(objMulter.any()); server.post('/',function(req,res){ //新檔名 //'./www/upload/akjdhaisuhdkjqawedhkajsd' + '.xxx' var newName=req.files[0].path+ pathLib.parse(req.files[0].originalname).ext; fs.rename(req.files[0].path,newName,function(err){ if(err) res.send('上傳失敗！'); else res.send('上傳成功！'); }); //1.獲取原始副檔名 //2.改字尾 }); server.listen(8082);
