所以我正在使用firebase数据库构建一个应用程序,并且有一部分我只想接收每个用户的某些属性。请允许我解释一下。这是我的数据结构:
{
"Users" : {
"JuBgk9ZjdrbP5fZVfmhdpF1FrjE3" : {
"birthday" : 857278800,
"email" : "*******@sas.upenn.com",
"full name" : "Neil Doe",
"gender" : "Female",
"gender_age" : 220,
"long bio" : "My name is Neilette, I wanna skoodlypoop you.",
"short bio" : "Life is actually cake!",
"username" : "Neildoe"
},
"QGqcGWCchCeFKQ6VTAgt9O2v3gs1" : {
"birthday" : 926395200,
"email" : "*******@yahoo.com",
"full name" : "John Doe",
"gender" : "Female",
"gender_age" : 218,
"username" : "Johndoe"
}
}
是否可以只收到每个用户的全名和生日?或者我是否必须提取全套数据?或者我应该像this answer中那样构建我的数据?
我在目标c中这样做,但任何语言的答案都会有所帮助!
