Question

我正在尝试使用s3FS在s3bucket上传图像。存储桶创建成功，但不知何故，我试图上传图像的api，给我一个错误，说你的路径没有定义。但是桶是在aws中创建的，但是图像不存在。

app.js

var express = require('express');
var mongoose = require('mongoose');
var fs = require('fs');
var S3FS = require('s3fs');
var s3fsImpl = new S3FS('folder', {
    accessKeyId: 'id',
    secretAccessKey: 'key'
});

s3fsImpl.create();

var multiparty = require('connect-multiparty'),
    multipartyMiddleware = multiparty();
var bodyParser = require('body-parser');
var jwt = require('jsonwebtoken');
// var multer = require('multer');
// var uuid = require("uuid");
var app = express();
var config = require('./config.js');
var morgan = require('morgan');
// var path = require('path');
var port = process.env.PORT || 3000;
var foodtrucklist = require('./controller/foodtrucklist.js');
var login = require('./controller/login.js');
var itemInfo = require('./controller/item_info.js');
var review = require('./controller/reviews.js');
var popularitems = require('./controller/popularitems.js');
var foodtruck = require('./model/datafoodtruck');
var truckData = require('./model/foodtruck.js');
var webToken = require('./controller/webtoken.js');
var userprofile = require('./controller/userprofile.js');
var notificationdata = require('./model/dataNotifications.js');
var notification = require('./controller/notifications.js');
var foodtruckItemList = require('./controller/item_list_foodtruck.js');
var orderList = require('./controller/orders_foodtruck.js');
var ordermanagement = require('./controller/ordermanagement.js');

var db = mongoose.connect('mongodb://127.0.0.1:27017/quflip');

mongoose.connection.once('connected', function() {
    console.log("Connected to database")
    foodtruck.save(function(err, foodtrucks) {
        if (err) res.send(err);
    });
    notificationdata.save(function(err, notifs) {
        if (err) res.send(err);
    });
});

app.use(multipartyMiddleware);
app.post('/testupload', function(req, res) {
    var file = req.files.file;
    var stream = fs.creatReadStream(file.path);
    return s3fsImpl.writeFile(file.originalFilename, stream).then(function() {
        fs.unlink(file.path, function(err) {
            if (err) console.error(err);
        })
        res.json({
            status:'200',
            message:'uploaded'
        })
    })
});

错误

使用node.js无法将图像上载到s3存储桶
