如何Postman POST json body并附加文件？

Question

我有后端API，允许用户 POST a json_body并使用文件：

@RequestMapping(value = "/sendemail",
            method = RequestMethod.POST,
            produces = MediaType.APPLICATION_JSON_UTF8_VALUE,
            consumes = {MediaType.MULTIPART_FORM_DATA_VALUE}
)
public @ResponseBody ResponseEntity<String> sendEmailToClients(
       @RequestBody String jsonData,
       @RequestParam(value = "file", required = false) final MultipartFile file) {
        ...
}

问题：在邮递员工具上，有没有办法让POST发送json_body和文件上传？
