当用户删除主集合时，我正在尝试将所有文件从 firebase 存储移动到同一 firebase 存储中的另一个路径，因此出现以下错误：
我尝试并使用了以下功能：
const restoreDeletedFile = (
storageRef,
fileArr,
personRecordId,
metadata,
convertToOriginalPath = false
) => {
// loop through files metadata
let restoreFilesPromises = fileArr.map((file, index) => {
return storageRef
.child(file.data().path)
.getDownloadURL()
.then((url) => {
// `url` is the download URL for the file
// This can be downloaded directly:
var xhr = new XMLHttpRequest();
xhr.responseType = "blob";
xhr.onload = () => {
let fileToUpload = xhr.response;
// upload a file to new path and remove the old one
// the new path = pr/id/image.jpeg
// the old path = deletedPR/pr/image.jpeg
return storageRef
// the new path
// convertToOriginal is to return filesName in the path as original
// ex: deletedPR/pr/fileName__documentId.extention to
// pr/fileName.extention
.child(
formatFilePath(
file.data(),
personRecordId,
FILE_PATH.ORIGINAL,
convertToOriginalPath
)
)
// the old path
.put(fileToUpload, metadata[index])
.then(() =>
// remove old path
storageRef.child(file.data().path).delete()
);
};
xhr.open("GET", url);
xhr.send();
return url;
});
});
return Promise.all(restoreFilesPromises);
};
如果我恢复一组文件，则上述功能在一种情况下有效，但如果我删除主集合并尝试使用所有链接的集合恢复已删除的文件，该功能将不起作用，它不会移动文件，我试过了和控制台记录所有代码，但没有错误，一切都符合预期。
当我调用该函数时，下面的代码显示：
.then(() =>
// fetch person record files
firestore
.collection("personRecords")
.doc("*deleted")
.collection("deletedRecords")
.doc(personRecordId)
.collection("files")
.get()
)
.then((docs) => {
fileArr = docs.docs;
// it saves the the docuemnet so good(I have checked firestore
// document
fileArr.map((doc) => {
return firestore
.collection("personRecords")
.doc(personRecordId)
.collection("files")
.doc()
.set({
docSource: doc.data().docSource,
lastModifiedDate:
doc.data().lastModifiedDate,
name: doc.data().name,
path: formatFilePath(
doc.data(),
personRecordId,
FILE_PATH.ORIGINAL
),
size: doc.data().size,
type: doc.data().type,
uploaderId:
doc.data().uploaderId,
});
});
})
.then(() => {
// fetch files metadata
let getDeletedMetaDataPromises =
fileArr.map((file, index) => {
return storageRef
.child(file.data().path)
.getMetadata();
});
return Promise.all(
getDeletedMetaDataPromises
);
})
.then((metadataSnapshot) => {
// metadata to use it later on..
metadata = metadataSnapshot.customMetadata;
return metadataSnapshot;
})
.then(() =>
// i have console log all the parameters and they are ok, but I
// still see the error above
restoreDeletedFile(
storageRef,
fileArr,
personRecordId,
metadata
)
)
有人遇到过这个问题吗？
