INTERMITTENT FirebaseFirestoreException：PERMISSION_DENIED：缺少权限或权限不足

标签： android firebase google-cloud-firestore firebase-security-rules

我有一个带有PeriodicWork的android应用，该应用每30分钟将数据写入Firestore。它工作正常，但我注意到在某些情况下，它会失败，但出现FirebaseFirestoreException: PERMISSION_DENIED例外。我不明白，如果它可以将数据写入Firestore，为什么会抱怨该权限。

// Firestore Rules
service cloud.firestore {
  match /databases/{database}/documents {

    match /bar/{document=**} {
      allow read: if true;
      allow create: if true;
    }

  }
}

// Write to Firestore
val firebaseFirestore = FirebaseFirestore.getInstance()

firebaseFirestore.collection(BAR_KEY)
        .add(barData)
        .addOnSuccessListener { /*success callback*/ }
        .addOnFailureListener { e ->
            Crashlytics.log(e.message)
            Crashlytics.logException(e)
            /* failure callback */
        }

Non-fatal Exception: com.google.firebase.firestore.FirebaseFirestoreException: PERMISSION_DENIED: Missing or insufficient permissions.

当您尝试再次更新同一文档时，它将失败。

将add（barData）更改为set（barData，SetOptions.merge（））

并在安全规则中添加以下行

allow update: if true;
