我正在开发一个swift的iOS应用程序,要求用户通过连接他们的Facebook帐户来创建帐户。一个月前,当我通过注册我自己的Facebook帐户进行测试时,Firebase创建的用户UID格式为" facebook:(facebook app id)"。这就是我想要的。
但是,最近,只要用户通过将Facebook帐户与我的应用程序相关联来创建新的acconut,Firebase就会使用随机字符串创建用户UID。例如:" E9FaL87wRmOKfhen2S6yszhCwtx1"。这可能是因为新的Firebase更新?我应该完成迁移过程吗?
以下是我创建帐户的代码:
@IBAction func facebookAuthAction(sender: AnyObject) {
let facebookLogin = FBSDKLoginManager()
facebookLogin.logInWithReadPermissions(nil, fromViewController: nil, handler: {(facebookResult, facebookError) -> Void in
if facebookError != nil {
print("Facebook login failed. Error \(facebookError)")
} else if facebookResult.isCancelled {
print("Facebook login was cancelled.")
} else {
let accessToken = FBSDKAccessToken.currentAccessToken().tokenString
FIREBASE_REF.authWithOAuthProvider("facebook", token: accessToken, withCompletionBlock: { error, authData in
if error != nil {
print("Login failed. \(error)")
} else {
print("Logged in! \(authData)")
NSUserDefaults.standardUserDefaults().setValue(authData.uid, forKey: "uid")
FIREBASE_REF.childByAppendingPath("users").observeEventType(.Value, withBlock: {snapshot in
if snapshot.hasChild(authData.uid) == false {
self.createNewFBUser(authData.uid)
}
})
self.performSegueWithIdentifier("loginSegue", sender: self)
}
})
}
})
}
func createNewFBUser(uid: String) {
var emailAddress:String = ""
var firstName:String = ""
var lastName:String = ""
var pictureURL:String = ""
let parameters = ["fields": "email, first_name, last_name, picture.type(large)"]
FBSDKGraphRequest(graphPath: "me", parameters: parameters).startWithCompletionHandler {(connection, result, error) -> Void in
if error != nil {
print(error)
return
}
if let email = result["email"] as? String {
emailAddress = email
}
if let first_name = result["first_name"] as? String {
firstName = first_name
}
if let last_name = result["last_name"] as? String {
lastName = last_name
}
if let picture = result["picture"] as? NSDictionary, data = picture["data"] as? NSDictionary, url = data["url"] as? String {
pictureURL = url
}
let newUser = [
"provider": "facebook",
"firstName": firstName,
"lastName": lastName,
"email": emailAddress,
"picture": pictureURL
]
FIREBASE_REF.childByAppendingPath("users").childByAppendingPath(uid).setValue(newUser)
}
}

将项目升级到new Firebase Console时,您的用户将迁移到新的身份验证后端。
升级后新创建的用户将获得新格式的uid。有关此更改的详细信息以及何时将其应用于现有(未升级的)Firebase应用,请参阅此post on the firebase-talk group。
请注意,Firebase建议多年来取决于uid
的格式。最好将其视为标识用户的不透明字符串。
