React Native-使用Firebase上传图像

Question

我正在使用expo，并且一直在尝试使用expo-image-picker将相机或图库中的本地图像上传到Firebase。到目前为止，这是我的代码：

const uploadImage = async (uri, imageName) => {
    const response = await fetch(uri);
    const blob = await response.blob();
    var ref = firebase
      .storage()
      .ref()
      .child("images/" + imageName);
    console.log(ref);
    return ref.put(blob);   };

  uploadImage(uri, "Test_image");

我不断收到此错误消息：

Possible Unhandled Promise Rejection (id: 0):
FirebaseStorageError {
  "code_": "storage/unauthorized",
  "message_": "Firebase Storage: User does not have permission to access 'images/Test_image'.",
  "name_": "FirebaseError",
  "serverResponse_": "{
  \"error\": {
    \"code\": 403,
    \"message\": \"Permission denied. Could not perform this operation\"
  }
}",
}
