我正在尝试处理上传到s3.amazonaws.com.
我写了两封回信：
1.从我的后端获取网址上传。
1.要把我的形象与'上传网址'从第一次回调s3。
但我无法从s3接收我上传的图像的URL。PUT请求后，我得到了一个空的响应。
我有这个代码：

// callback for getting upload url from my backend - works OK
const getPresignedUrl = useCallback(
  async (imageName: string) => {
    const configurationObject = {
      method: 'get',
      url: getUploadUrl(imageName, uploadImageCategory.AVATARS),
      headers: {
        Authorization: `Bearer ${token}`,
      },
    };
    const {data} = await axios(configurationObject);
    return data;
  },
  [getUploadUrl, token],
);

// function to get image body from uri - also OK
const getBlob = async (fileUri: string) => {
  const resp = await fetch(fileUri);
  const imageBody = await resp.blob();
  return imageBody;
};

// callback that puts my image to s3 server - seems like it's OK
const uploadUsingPresignedUrl = useCallback(
  async (preSignedUrl: string) => {
    const imageBody = await getBlob(uri);

    const configurationObject = {
      method: 'PUT',
      url: preSignedUrl,
      data: {
        body: imageBody,
      },
    };

    const {data} = await axios(configurationObject);
    return data;
  },
  [uri],
);

在下面的代码中，我调用这些函数：

const onUploadImage = useCallback(async () => {
  const imageName = getImageName(uri); //just util for getting right image name

  const presignedUrl = await getPresignedUrl(imageName);
  console.log('presignedUrl', presignedUrl); // I see generated URL in response

  const putImageOnAws = await uploadUsingPresignedUrl(presignedUrl);
  console.log('putImageOnAws', putImageOnAws); // Response is empty

}, [getImageName, getPresignedUrl, uploadUsingPresignedUrl, uri]);

useEffect(() => {
  if (uri) {
    setAvatar(uri);
    onUploadImage()
      .then()
      .catch(err => console.log('err: ', err));
  }
}, [onUploadImage, uri]);

所以当我调用putimageonaws时，我得到了空的响应。我认为应该有一个链接到我上传的图像...
所以我的问题是-我怎样才能得到我的图片上传到s3的网址？
