Question

所以我在我的代码中有这个firebase对象，我试图保存：

{"Education/schoolName": "RIT", 
"Education/major": "Computer Science", 
"Education/startYear": "November 25, 2015", 
"Education/endYear": "November 30, 2015"}

尝试运行我的代码时出现此错误：

Error: Firebase.update failed: First argument  contains an invalid key ("Education/schoolName") in property 'users.235642888'.  Keys must be non-empty strings and can't contain ".", "#", "$", "/", "[", or "]"

我的角度服务看起来像这样：

function saveUserDetails(email,object){
        var hashedEmail = Utilities.getHashCode(email);
        object = angular.fromJson(angular.toJson(object));
        object = Utilities.flattenObject(object,{});
        var userRef = ref.child(hashedEmail);

        console.log("Saving object ",object);
        return $q(function(resolve,reject){
            return userRef.update(object, function(error){
                if(error){
                    reject(error);
                }else{
                    resolve("Updated successfully!");
                }
            });
        });
    }

但是当我在Chrome控制台中尝试做同样的事情时：

ref.update({"Education/schoolName": "RIT", 
"Education/major": "Computer Science", 
"Education/startYear": "November 25, 2015", 
"Education/endYear": "November 30, 2015"});

该对象在firebase中成功保存。我不知道为什么通过我的代码没有成功，因为在两种情况下对象都保持不变。

非常感谢任何帮助。

您使用的是Firebase客户端库的过时版本，该版本不支持深层路径更新。截至今天，2015年11月21日的最新版本是2.3.2。
