Firebase权限随机被拒绝
[英]Firebase permission denied randomly
问题描述
I had my security rules set up and everything was working fine yesterday. 
我设置了安全规则，昨天一切正常。 I've changed nothing since but today I keep getting "Permission denied" when I try to run this transaction on "styles/$styleId/likeInfo": 我没有改变，但是今天当我尝试在“styles / $ styleId / likeInfo”上运行此事务时，我一直收到“权限被拒绝”：

My security rules: 我的安全规则：
{
"rules": {
".read": "auth != null",
"sessions":{
"$uid": {
".write": "$uid === auth.uid"
}
},
"styles":{
"$styleid":{
"likeInfo": {
".write": "auth!= null",
"filters":{
".validate": "newData.val() == data.val()"
},
"likeCount": {
".validate": "newData.isNumber() && newData.val() == data.val()+1"
},
"likeModified": {
".validate": "newData.val() == now"
}
}
}
},
"stylefilters":{
"$filterCombo":{
"$styleId":{
"likeCount": {
".write": "auth!= null",
".validate": "newData.isNumber() && newData.val() > data.val()"
},
"likeModified":{
".write": "auth!= null",
".validate": "newData.val() > data.val()"
}
}
}
}
}
}
I know the user is authenticated as I'm printing the user object: D/SwipeListener: User: com.google.android.gms.internal.zzafu@a507f090 and the data being sent seems to fit the validation rules I've specified. 我知道用户在打印用户对象时已经过身份验证： D/SwipeListener: User: com.google.android.gms.internal.zzafu@a507f090并且发送的数据似乎符合我指定的验证规则。
My firebase version: 我的firebase版本：
compile 'com.google.firebase:firebase-auth:9.4.0'
compile 'com.google.firebase:firebase-database:9.4.0'
Update: 更新：
This is the java code running the transaction: 这是运行事务的java代码：
public class LikeCountTransaction {
public static final String PATH = "styles/%s/likeInfo";
private final DatabaseReference databaseReference;
@Inject public LikeCountTransaction(DatabaseReference databaseReference) {
this.databaseReference = databaseReference;
}
public Observable<DataSnapshot> execute(Long styleId) {
String path = String.format(PATH, styleId);
Timber.d("Transaction path: %s", path);
return Rx.transact(databaseReference.child(path), mutableData -> {
MutableData likeCount = mutableData.child("likeCount");
Long likeCountValue = likeCount.getValue(Long.class);
if (likeCountValue != null) {
likeCount.setValue(likeCountValue + 1);
mutableData.child("likeModified").setValue(ServerValue.TIMESTAMP);
}
return Transaction.success(mutableData);
}).toObservable();
}
}
This is where the PermissionDenied Error is thrown: 这是抛出PermissionDenied错误的地方：
public static Single<DataSnapshot> transact(DatabaseReference databaseReference, TransactionExecutor handler) {
return Observable.<DataSnapshot>fromEmitter(emitter -> databaseReference.runTransaction(new Transaction.Handler() {
@Override public Transaction.Result doTransaction(MutableData mutableData) {
return handler.execute(mutableData);
}
@Override public void onComplete(DatabaseError databaseError, boolean committed, DataSnapshot dataSnapshot) {
if (committed) {
emitter.onNext(dataSnapshot);
emitter.onCompleted();
} else {
if (databaseError != null) {
emitter.onError(databaseError.toException()); <------------------ Permission Denied Error
} else {
emitter.onError(new Throwable("Transaction did not commit"));
}
}
}
}), AsyncEmitter.BackpressureMode.LATEST).toSingle();
}

I had to change the validation rule on my "filters" to 我必须将我的“过滤器”上的验证规则更改为
"filters":{
"$filterIndex": {
".validate": "newData.val() == data.val()"
}
}
I guess the rules don't evaluate two arrays to be equal even if they have the same data. 我猜这些规则不会评估两个数组是否相等，即使它们具有相同的数据。
