[英]Unable to delete Firebase Storage Image with Cloud Function
將此問題的存儲路徑從“yourmaps”更改為“users” 嘗試從 Firebase 存儲中刪除圖像。 我已經閱讀了類似的堆棧溢出問題,並試圖在幾天內毫不費力地解決這個問題。
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const {Storage} = require('@google-cloud/storage');
admin.initializeApp();
刪除用戶帳戶后,會將用戶 uuid 傳遞到雲 function。 我正在嘗試刪除 firebase 存儲中具有相同 uuid 的用戶圖像。
exports.storageImageDelete = functions.firestore
.document('user/{userId}')
.onDelete(async (snapshot, context) => {
const userId = context.params.userId
const path = `users/${userId}.jpg`;
const bucketName = 'xxxxxxx.appspot.com/'
const storage = new Storage();
return storage.bucket(bucketName).file(path).delete()
.then(function () {
console.log(`File deleted successfully in path: ${path}`)
})
.catch(function (error) {
console.error(storage.bucket(bucketName).file(path).delete())
console.info(storage.bucket(bucketName).file(path).delete())
console.log(`File NOT deleted: ${path}`)
})
});
Firebase 存儲日志中的錯誤消息。 路徑是正確的,但是沒有 object...
Error: No such object: xxxxxx.appspot.com/users/XXXXXXXXXX-XXXX-XXXX-XXXXXXXXXXX.jpg
在 Firebase 存儲“監控規則”中,我可以看到我的嘗試是允許的。 任何幫助,將不勝感激。 我錯過了什么?
由於它是您的默認存儲桶,因此以下內容應該可以解決問題(未經測試):
then
的版本(不使用 async/await)const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.storageImageDelete = functions.firestore
.document('user/{userId}')
.onDelete((snapshot, context) => {
const userId = context.params.userId
const path = `users/${userId}.jpg`;
const bucket = admin.storage().bucket();
return bucket.file(path).delete()
.then(() => {
console.log(`File deleted successfully in path: ${path}`)
return null;
})
.catch(error => {
console.log(`File NOT deleted: ${path}`);
return null;
})
});
async
/ await
的版本exports.storageImageDelete = functions.firestore
.document('user/{userId}')
.onDelete(async (snapshot, context) => {
try {
const userId = context.params.userId
const path = `users/${userId}.jpg`;
const bucket = admin.storage().bucket();
await bucket.file(path).delete();
console.log(`File deleted successfully in path: ${path}`)
return null;
} catch (error) {
console.log(`File NOT deleted: ${path}`);
console.log(error);
return null;
}
});
也就是說,不需要像你這樣聲明bucket,你可以直接用admin.storage().bucket()
來聲明。
我終於解決了我的問題。 這是正確找到我的存儲桶所需的缺失代碼。
admin.initializeApp({
databaseURL: "https://xxxxxxxx.firebaseio.com",
storageBucket: "xxxxxxxx.appspot.com"
});
