图像删除产生错误：“Uncaught FirebaseError: Firebase Storage: The operation 'deleteObject' cannot be performed on a root reference”

Question

我正在尝试删除 firebase 存储和 firestore 中的文档，但出现错误。我正在使用反应。

const onDelete = (e) => {
    const { url } = e.target;
    console.log("Url", url);
    const deleteRef = ref(storage, url);

    deleteObject(deleteRef)
      .then(() => {
        console.log("Item was deleted from Firebase Storage", deleteRef);
      })
      .catch((error) => {
        console.log(error.message);
        toast.error(error.message);
      });

    const imageDelete = db.collection("images").where("imageURL", "==", url);
    imageDelete.get().then(function (querySnapshot) {
      querySnapshot.forEach(function (doc) {
        doc.ref.delete();
      });
      console.log("Image should have been deleted from Firestore");
    });
  };

我得到的错误是：

Uncaught FirebaseError: Firebase Storage: The operation 'deleteObject' cannot be performed on a root reference, create a non-root reference using child, such as .child('file.png'). (storage/invalid-root-operation)

如错误消息所述，您正在尝试删除存储桶的根 - 这是不可能的。

从查看构建参考的代码来看，

url

似乎是空的，因此您需要检查从中获得的输出：

console.log("Url", url);
