我有一個簡單的Firestore數據庫，只有少數國家和每個國家/地區的城市。考慮每個國家的文件，即法國。同時使用請求變量讀取文檔面臨PERMISSION_DENIED異常以下兩種情況。Cloud Firestore - 請求變量未按預期工作
，供大家參考分享以下幾點 1）公司的FireStore配置 2），這是不工作 3）相關日誌每次失敗 3）類文件創建和讀取公司的FireStore數據庫 4）方法調用下面的具體配置場景
方案1 - 2之後應許可工作中的至少一種，但兩者都沒有工作
allow read : if request.resource.__name__ != null ;
allow read : if request.resource.__name__ == null ;
錯誤日誌
I/System.out的：firestoreTest ACTION_READ onFailureListener E = com.google.firebase.firestore.FirebaseFirestoreException：PERMISSION_DENIED：缺少或權限不足。 I/System.out的：firestoreTest getOnCompleteListener不成功
方案2 - 儘管文件名 '法國' 在數據庫中存在，它不工作。
allow read : if request.resource.__name__ == /databases/$(database)/documents/Countries/france ;
錯誤日誌
I/System.out的：FireStoreTest.firestoreTest動作= [2]，國= [法國]，hashmapCountry = [零] I/System.out的：firestoreTest ACTION_READ onFailureListener e = com.google.firebase.firestore.FirebaseFirestoreException：PERMISSION_DENIED：權限缺失或不足。 I/System.out的：firestoreTest getOnCompleteListener不成功
方案3 - 沒有問題，而且運作良好。只有提出，因爲類似的情景2不工作
allow read : if resource.__name__ == /databases/$(database)/documents/Countries/france ;
錯誤日誌
I/System.out的：FireStoreTest.firestoreTest行動= [2]，國= [法國]，hashmapCountry = [空] I/System。出：firestoreTest getOnCompleteListener成功{城市=巴黎}
基本配置測試場景
service cloud.firestore {
match /databases/{database}/documents
{
match /Countries/{country}
{
allow write : if true ;
allow read : // replace as per below scenario
}
}
}
}
方法來創建集合，僅需要被稱爲試驗前一次
HashMap<String, String > hashMap = new HashMap<>() ;
hashMap.put("city","paris") ;
fireStoreTest.firestoreTest(fireStoreTest.ACTION_ADD,"france",hashMap);
方法可用於測試所有以下3場景
fireStoreTest.firestoreTest(fireStoreTest.ACTION_READ,"france",null);
下面類是用來測試上述3個場景
package com.firestoreTest ;
import com.google.firebase.firestore.DocumentReference;
import com.google.firebase.firestore.DocumentSnapshot;
import com.google.firebase.firestore.FirebaseFirestore;
import java.util.HashMap;
import java.util.Map;
public class FireStoreTest {
public static final int ACTION_ADD = 1 ;
public static final int ACTION_READ = 2 ;
private FirebaseFirestore firebaseFirestore ;
public FireStoreTest() {
firebaseFirestore = FirebaseFirestore.getInstance() ;
}
public void firestoreTest(int action, String country, HashMap hashmapCountry)
{
System.out.println("FireStoreTest.firestoreTest action = [" + action + "], country = [" + country + "], hashmapCountry = [" + hashmapCountry + "]");
DocumentReference documentReference = firebaseFirestore.collection("Countries").document(country) ;
switch (action)
{
case ACTION_ADD:
documentReference.set(hashmapCountry)
.addOnFailureListener(e-> System.out.println("firestoreTest ACTION_ADD onFailureListener e = "+e) )
.addOnCompleteListener(task -> {
if (task.isSuccessful())
{
System.out.println("firestoreTest setOnCompleteListener Successful ");
} else
{
System.out.println("firestoreTest setOnCompleteListener Unsuccessful " +task.getException());
}
}) ;
break ;
case ACTION_READ:
documentReference.get()
.addOnFailureListener(e-> System.out.println("firestoreTest ACTION_READ onFailureListener e = "+e))
.addOnCompleteListener(taskDocumentSnapshot->{
if (taskDocumentSnapshot.isSuccessful())
{
DocumentSnapshot documentSnapshot = taskDocumentSnapshot.getResult() ;
if (documentSnapshot.exists())
{
Map mapDocumentSnapshot = documentSnapshot.getData() ;
System.out.println("firestoreTest getOnCompleteListener Successful "+mapDocumentSnapshot);
} else
{
System.out.println("firestoreTest getOnCompleteListener no data found ");
}
} else
{
System.out.println("firestoreTest getOnCompleteListener Unsuccessful ");
}
}) ;
break ;
}
}
}所有
