axios - 将文件和数据从多部分解析到使用 axios 调用的羽毛服务

Question

我已经通过使用“羽毛生成服务”创建了这个服务 - 并选择了 sequalized 我希望能够使用 axios 从客户端调用该服务，目前我的 axios 调用如下所示：

  const formData = new FormData()
  formData.append('serverPath', 'some path')
  await this.$axios.post(`${process.env.BACKEND}/uploadb`, formData, {
      timeout: -1,
      headers: { Authorization: `Bearer ${that.$store.state.auth.accessToken}` },
      cancelToken: this.$options.source.token,
              onUploadProgress: (event) => {
                that.progress = Math.round((event.loaded * 100) / event.total)
              },
              onError: (error) => {
                systemlog.create({ user: that.$store.state.auth.user == null ? 'unknown' : that.$store.state.auth.user.username, component: 'fileupload', method: 'submin', logtype: 'info', module: 'client', text: 'error:' + error })
              }
            })

我的服务是这样的

    // Initializes the `uploadb` service on path `/uploadb`
    const { Uploadb } = require('./uploadb.class');
    const createModel = require('../../models/uploadb.model');
    const hooks = require('./uploadb.hooks');
    const fs = require('fs');
    const feathers = require('@feathersjs/feathers');
    const configuration = require('@feathersjs/configuration');
    const appconfig = feathers().configure(configuration());
    const path = require('path');
    const destbase = appconfig.get('uploadpath');

module.exports = function (app) {
  const options = {
    Model: createModel(app),
    paginate: app.get('paginate')
  };

  // Initialize our service with any options it requires
  app.use('/uploadb', async (req, res,next) => {
    
    

    req.pipe(req.busboy); // Pipe it trough busboy
    req.busboy.on('file', (fieldname, file, filename) => {

      // req.body.serverpath is undefined here
      // I have set serverPath in the forData object like this
      // formData.append('serverPath', that.newserverpath)

      let dest = destbase+'/'+req.body.serverPath;
      console.log(`Upload of '${path.join(dest, filename)}' started`);
      // the values i set here is stored in the database
      req.body.filename=filename;

      // Create a write stream of the new file
      const fstream = fs.createWriteStream(path.join(dest, filename));
      // Pipe it trough
      file.pipe(fstream);
 
      // On finish of the upload
      fstream.on('close', () => {
        console.log(`Upload of '${filename}' finished`);
        //res.send(res.data);
        next();
          
      });
    });
  },new Uploadb(options, app));
  // Get our initialized service so that we can register hooks
  const service = app.service('uploadb');
  service.hooks(hooks);
};

几乎可以工作 - 文件已保存 - 并将一行写入 updateb 表 - 但在我使用 multer 找到的另一个示例中 - req.body 已填充 - 我需要做什么才能让服务存储数据我在formdata中附加到数据库？
