使用SAILJS POST和GET图像不起作用（错误：[object，Object]）上传图片

Question

这是我的代码，它被称为sails文档我想上传文件控制器操作的图像，并通过用户控制器操作上传和获取它上传和存储它。它没有显示它的节目

error: [object, Object].

文件控制器操作 用于上传图片

// myApp / api / controllers / FileController.js

module.exports = {

  index: function (req, res) {

    res.writeHead(200, {
      'content-type': 'text/html'
    });
    res.end(
      //'<form action="http://localhost:1337/file/upload" enctype="multipart/form-data" method="post">'+
      '<form action="http://localhost:1337/user/avatar" enctype="multipart/form-data" method="post">' +
      '<input type="text" name="title"><br>' +
      '<input type="file" name="avatar" multiple="multiple"><br>' +
      '<input type="submit" value="Upload">' +
      '</form>'
    )
  },
  /**

   * Upload avatar for currently logged-in user

  uploadAvatar: function (req, res) {
    console.log('avatar', req.method);
    console.log(req.session.me);
    req.file('avatar').upload({
      // don't allow the total upload size to exceed ~10MB
      maxBytes: 10000000
    }, function whenDone(err, uploadedFiles) {
      if (err) {
        return res.negotiate(err);
      }
      console.log(uploadedFiles);

      // If no files were uploaded, respond with an error.
      if (uploadedFiles.length === 0) {
        return res.badRequest('No file was uploaded');
      }


      // Save the "fd" and the url where the avatar for a user can be accessed

        .exec(function (err) {
