我的代码:

  const file = {
    uri: this.state.imageSource,
    name: this.state.imageName,
    type: "image/jpg"
  }
  const data = new FormData();
  data.append("file", file);

  fetch(config.server + "/upload", {
    method: "POST",
    body: data
  })
    .then(res => res.json())
    .then(responseData => {
      alert(JSON.stringify(responseData));
    })
    .catch(err => {
      alert(err);
    });

没有FormData代码不显示错误.我应该怎么做才能解决？在android上调试.
