从Firebase数据库获取数据，返回时没有键值

Question

I am retrieving data from Firebase db using REST call. So i have a data looking like this

user
{
    123456: 
     {
       Email: "test@hotmail.com", 
       Password: "John Doe"
     }

    654321: 
     {
       Email: "test2@hotmail.com", 
       Password: "Jane Doe"
     }
}

The query I used is

firebaseurl/user.json?orderBy="Email"&equalTo="test@hotmail.com"

Is it possible if I query without the key value 123456 being retrieve? Because whenever I try to use the data, for instance console.log(user.Email) , I am getting undefined. But when I do it like console.log(user[123456].Email) then will I get the result I desire.

May I know if there's a way to do it? Or a way to access to the child element without user[keyvalue] .

As it is expected only single record in return you can use: const user = obj[Object.keys(rslt)[0]]

Or you can loop over the keys

const usersArr = Object.keys(rslt).map(usr => {
    ... manipulate usr 
    return usr
})
