Question

我的安全规则如下所示：

{
  "rules": {
    ".read": false,
    ".write": "auth.user != null && newData.child('user').val() == auth.user"
  }
}

基本上，没有人（管理员用户除外）可以阅读，并且用户只能在他们提供相同的用户时才能写＃34;密钥，因为他们验证。

在Firebase模拟器中，一切正常。没有读取，只有经过正确认证的写入：

Attempt to write {"data":"Some Data","user":"testuser1"} to / with auth={"user":"testuser1"}
/:.write: "auth.user != null && newData.child('user').val() == auth.user"
    => true

Write was allowed.

这是我的代码（node.js）：

var FirebaseTokenGenerator = require("firebase-token-generator");
var tokenGenerator = new FirebaseTokenGenerator(FIREBASE_SECRET_TOKEN);

var Firebase = require('firebase');
Firebase.enableLogging(true, true);

var userID = "testuser1";

var client = new Firebase(FIREBASE_URL);
var clientToken = tokenGenerator.createToken({user: userID});

client.auth(clientToken, function(error){
if (error){
    console.log("Client login failed")
} else {
    console.log("Client login success");

    client.push({user: userID, data: "Some Data"}, function(error){
        if (error){
            console.log("Write Error: " + error);
        } else {
            console.log("Write success");
        }
    });
}
});

奇怪的是，在client.push我收到Firebase的Permission Denied错误。

以下是启用日志记录时Firebase库打印到日志的内容：

我做错了什么？为什么我从模拟器和我的代码得到不同的响应？

典型 - 现在我已将问题发布到StackOverflow，我设法解决了这个问题。

以下是我的新安全规则 - 客户端代码保持不变：

{
    "rules": {
        ".read": false,
        ".write": false,
        "$": {
          ".read": false,
          ".write": "auth.user != null && newData.child('user').val() == auth.user",
        }
    }
}

Firebase安全规则适用于模拟器，但不适用于代码
