更新：代码

var express =   require("express");
var multer    =    require('multer');
var router = express.Router();
var logwrite = require('./logwrite');
var storage =   multer.diskStorage({
  destination: function (req, file, callback) {
    callback(null, __dirname);
  },
  filename: function (req, file, callback) {
    callback(null, 'aasasa-' + Date.now());
  }
});

var upload = multer({ storage : storage}).single('userPhoto');

router.post("/upload", function(req,res){
  // res.send(" we got it !!")
  upload(req,res,function(err) {
        if(err) {
            return res.end("Error uploading file.");
        }
    else{
      res.end("File is uploaded" + __dirname);
    }

    });
});
module.exports = router;
