话不多说 直接看代码
var fs=require('fs') var multer = require('multer') var createFolder=function(folder){ //创建文件夹的方法 try{ fs.accessSync(folder) }catch(e){ fs.mkdirSync(folder) } } var uploadFolder='./upload/' createFolder(uploadFolder) var storage = multer.diskStorage({ destination: function (req, file, cb) {//存放的文件夹 cb(null, uploadFolder) }, filename: function (req, file, cb) { console.log(file.originalname,'cc') cb(null, file.fieldname + '-' + Date.now()) //存放的名字 } }) var upload = multer({ storage:storage })
//上传文件的接口
app.post('/upload',upload.single('logo'),function(req,res){
console.log(req.file) //原文件的名字 originalname
res.send({'ret_coder':0})
})
