Fille上传node.js，multer，imagemagick无法正常工作

以下是我的代码。 我在MVC模板中使用express。

我使用邮递员在表格数据模式下testing这条路线。 目录是public/images/avatar/1510932719839-BHqhegjFMc3Qf/只有我上传的文件（图片）不在其中。 我没有收到任何错误，没有任何问题，没有崩溃。

app.js

 let routes = require('./routes')(app, dbPool, passport, redisClient); app.use(express.static('public')); app.get("*", function (req, res) { fs.createReadStream("./public/index.html").pipe(res); }); app.use(bodyParser.urlencoded({ extended: true, limit: '50mb', parameterLimit: 10000 })); app.use(bodyParser.json()); app.listen(80); 

fileUploadRoute.js

 let FileUploadController = require('./../controllers/fileUploadController'); module.exports = function (app, dbPool, passport, redisClient) { let fileUploadController = new FileUploadController(dbPool, redisClient); let uploadRouteImage = "/api/upload/image/"; let uploadRouteFile = "/api/upload/file/"; app.route(uploadRouteImage + "avatar") .post(fileUploadController.imageUploaderAvatar ); } 

fileUploadController.js

 let cast = require('model-generator').Cast; let jwt = require('json-web-token'); let PhotoUploadService = require('./../services/fileUpload/photoUploadService'); let coreFunctions = require('./../core_classes/CoreFunctions'); let photoUploadService, pdfUploadService; module.exports = class FileUploadController { constructor(dbPool, redisClient) { photoUploadService = new PhotoUploadService(dbPool, redisClient); pdfUploadService = new PdfUploadService(dbPool, redisClient); } imageUploaderAvatar(req, res) { let promises = [ coreFunctions.randomFileNameGenerator() //return: 1510932719839-BHqhegjFMc3Qf ]; let promisesResults; Promise.all(promises) .then(result => { photoUploadService.storage(result[0], 'avatar', 255, 255) .then(storage => { photoUploadService.upload(req.file, storage) .then(result => { res.status(200).json({status: "Success"}) }) .catch(error => { res.status(400).json({error: "Something went wrong."}) }) }) .catch(error => { console.log(error); res.status(400).json({error: "Something went wrong."}) }) }) .catch(error => { console.log(error); res.status(400).json({error: error}) }); } 

photoUploadService.js

 let multer = require('multer'); let path = require('path'); let imager = require('multer-imager'); module.exports = class PhotoUploadService { constructor(dbPool, redisClient) { this.fileUploadRepository = new FileUploadRepository(dbPool); this.redisClient = redisClient; } storage(fileName, type, width = 255, height = 255) { return new Promise((resolve, reject) => { let location = `./public/images/${type}/${fileName}/`; resolve( imager({ bucket: 'bucket-name', location: location, dirname: 'avatar', accessKeyId: 'string', region: 'us-east-1', acl: 'public-read', secretAccessKey: 'string', filename: fileName, gm: { width: width, height: height, format: 'jpg' } }) ) }) } upload(fieldname, storage) { return new Promise((resolve, reject) => { multer({ storage: storage, limits: {fileSize: 1500000000000} }).single(fieldname); resolve(true); }) } }
