	  	var str = file.originalname.split('.');
	    cb(null, Date.now()+'.'+str[1]);
  	}
})
var upload = multer({ storage: storage });
app.post("/uploadImgs",upload.array("file",20),function(req,res,next){
	
	var arr = [];
	for(var i in req.files){
		
		arr.push(req.files[i].path);
	}
	res.json({
		code:200,
