vue中axios 的post

这是vue

 axios({
          method:'post',
          url: "http://localhost:8000/api/download" ,
          headers:{
            "Content-Type":"multipart/form-data;boundary=<calculated when request is sent>",
            'Authorization':this.$cookies.get('Authorization')
          },
          data: {
            path: this.$data.paths + '\/' + name // /123/Login.JPG
          },
          responseType: 'blob'

这是控制类接收

 public void downLoad(@RequestParam("path") String path

结果是浏览器发送失败

报错:
Resolved [org.springframework.web.bind.MissingServletRequestParameterException: Required request parameter 'path' for method parameter type String is not present]

但是postman请求就成功

学艺不精 哭 求指点

form data格式的数据需要这样传

const formData = new FormData()
formData.append('path', this.$data.paths + "\/" + name)
axios({
  method: "post",
  url: "http://localhost:8000/api/download",
  headers: {
    "Content-Type": "multipart/form-data;boundary=<calculated when request is sent>",
      Authorization: this.$cookies.get("Authorization"),
  },
  data: formData,
  responseType: "blob",
});

有配置跨域吗？端口不一样也属于跨域
