Node.js 如何在featherjs中处理文件上传？

我试图使用multer处理feathersjs中的多部分表单文件上载，我尝试使用

blobService

和

blobStorage

将

req.picture

中包含的文件复制到服务器，并获取文件的url，然后用返回的url替换

req.picture

。之后，

req

应移交给

feathers mongoose

以保存在数据库中。通过查阅官方文件，我得出了以下结论，但我一无所获

Items服务|也只有当我将

blobService（{Model:blobStorage}）

更改为

createService（options）

时，其他方法（如get）才起作用，否则不会起作用

    // Initializes the `items` service on path `/items`
const createService = require('feathers-mongoose');
const createModel = require('../../models/items.model');
const hooks = require('./items.hooks');
const filters = require('./items.filters');
const multer = require('multer');
const multipartMiddleware = multer();
const blobService = require("feathers-blob");
const fs = require("fs-blob-store");
const blobStorage = fs("./public/items/pictures");

module.exports = function () {
  const app = this;
  const Model = createModel(app);
  const paginate = app.get('paginate');

  const options = {
    name: 'items',
    Model,
    paginate
  };

  // Initialize our service with any options it requires
  app.use('/items',
    multipartMiddleware.single('picture'),
    function(req, res, next){
      req.feathers.file = req.picture;
      req.picture = 'url to the file';
      next();
    },
    blobService({ Model: blobStorage}));

  // Get our initialized service so that we can register hooks and filters
  const service = app.service('items');

  service.hooks(hooks);

  if (service.filter) {
    service.filter(filters);
  }
};

项目服务挂钩

const { authenticate } = require('feathers-authentication').hooks;
const fileUpload = require('../../hooks/file-upload').hooks;

module.exports = {
  before: {
    all: [ authenticate('jwt') ],
    find: [],
    get: [],
    create: [fileUpload],
    update: [fileUpload],
    patch: [],
    remove: []
  },

文件上传挂钩（file upload.js）

这是我在《邮差》上得到的回应

    {
    "name": "GeneralError",
    "message": "Cannot read property 'startsWith' of undefined",
    "code": 500,
    "className": "general-error",
    "data": {},
    "errors": {}
}

请尝试调试模式（）以查看所获得错误的更多详细信息。我最终删除了blob存储和blob服务，并将multer配置为保存文件，但我仍然不知道如何使用feathers执行此操作-blob@v1shva你有这方面的例子吗。我也有问题

    {
    "name": "GeneralError",
    "message": "Cannot read property 'startsWith' of undefined",
    "code": 500,
    "className": "general-error",
    "data": {},
    "errors": {}
}
