如何从Firebase中检索当前用户的数据 [英] How to retrieve data of current user from firebase
问题描述
我坚持从当前用户检索数据。
在我的firebase现在我有这样的结构:
我决定通过uid获取用户数据。
所以我初始化了变量
pre $ let userID = FIRAuth.auth()?currentUser?.uid
然后从数据库中检索一个对象数组
<$ p在
print(snapshot.value as![String:AnyObject])中的observeEventType(.Value,withBlock:{(snapshot) !)
))
}
在我的输出中,我有这个:
-KJSKE4a2y-okl71vDSx:{
兴趣=男人;
性别=女性;
name = girlsname1;
photo =http://i.imgur.com/VAWlQ0S.gif;
surname = girlsurname1;
},-KJSKE4b8TlvxV-urHQo:{
Interest = men;
性别=女性;
name = girlsname6;
photo =http://media.tumblr.com/tumblr_lnb9aozmM71qbxrlp.gif;
surname = girlsurname6;
等等
没关系,但我的目标是打印当前授权用户的数据。我有一个由uid排序所有对象的想法,但我认为这是不合理的。希望有更简单的解决方案。
$ b 授权用户存储在用户数据库中。个人资料数据库包含我从Facebook获得的用户参数。
let userID: String =(FIRAuth.auth()?。currentUser?.uid)!
print(当前用户ID是+ userID)
self.dbRef?.child(profile)。child(userID).observeSingleEvent(of:.value,with:{ (快照)
print(snapshot.value)
let userEmail =(snapshot.value as!NSDictionary)[addedByUser] as!String
print(userEmail)
})
I'm, developing a simple app to store users images. User authorized via Facebook, and the interact with app. I stuck with retrieving data from current user.
In my firebase for now I have such structure:
I decided to get user data by uid. So I initialized variable
let userID = FIRAuth.auth()?.currentUser?.uid
Then I retrieve an array of objects from my database
URL_BASE.child("profile").observeEventType(.Value, withBlock: { (snapshot) in
print (snapshot.value as! [String:AnyObject]!)
})
}
In my output I have this:
"-KJSKE4a2y-okl71vDSx": {
Interest = men;
gender = female;
name = girlsname1;
photo = "http://i.imgur.com/VAWlQ0S.gif";
surname = girlsurname1;
}, "-KJSKE4b8TlvxV-urHQo": {
Interest = men;
gender = female;
name = girlsname6;
photo = "http://media.tumblr.com/tumblr_lnb9aozmM71qbxrlp.gif";
surname = girlsurname6;
And so on
It is ok, but my goal is to print data of currently authorized user. I have an idea of sorting all objects by uid, but I think it is irrational. Hope there is simpler solution.
Authorized users stores in users database. profile database consist of user parameters I'm getting from Facebook.
let userID : String = (FIRAuth.auth()?.currentUser?.uid)!
print("Current user ID is" + userID)
self.dbRef?.child("profile").child(userID).observeSingleEvent(of: .value, with: {(snapshot) in
print(snapshot.value)
let userEmail = (snapshot.value as! NSDictionary)["addedByUser"] as! String
print(userEmail)
})
