将 formData 传递给 Express 中间件，Req.body 返回空对象

Question

我正在尝试从客户端获取 formData，

 <!-- begin snippet: js hide: false console: true babel: false -->

/**
 * @swagger
 * /post_image_question:
 *   post:
 *     description: Post an image question
 *     parameters:
*       - name: question
 *         description: Object of userId and questions array
 *         type: object
 *         in: formData
 *         properties:
 *           userId:
 *             type: string
 *           questions:
 *             type: array
 *             items:
 *               type: object
 *               properties:
 *                 question_title:
 *                   type: string
 *                 question_description:

 *         description: The question in form of image
 *         type: file
 *         in: formData
 *         consumes:
 *         - multipart/form-data
  *     responses:
