新的Firebase：动态更改数据库URL [英] New Firebase: Changing Database URL dynamically

问题描述

在旧的Firebase中，我曾经能够在运行时动态地获取对不同数据库的引用（例如，在dev和prod数据库之间切换，甚至切换到用户定义的数据库URL），因为数据库URL已经传递在新的Firebase中，数据库URL（以及其他设置）位于 GoogleService-Info .plist 。

还有可能以旧的方式做我做的事吗？还是有另一种推荐的方式来实现呢？

解决方案

好吧，无论如何我找到了答案。

  let firOptions = FIROptions（googleAppID：googleAppID），而不是通常的设置，您必须手动初始化应用程序，bundleID：bundleID，GCMSenderID：GCMSenderID，APIKey：nil，clientID：nil，trackingID：nil，androidClientID：nil，databaseURL：databaseURL，storageBucket：nil，deepLinkURLScheme：nil）$ b $ FIRApp.configureWithOptions（firOptions）
 
 let firebaseRef = FIRDatabase.database（）。reference（）

In the old Firebase, I used to be able to get reference to different database dynamically at run time (say, switching between dev and prod db, or even switching to a user-defined database URL) because the database URL is passed in as a string when instantiating a db reference.

In the new Firebase, the database URL (along with other settings) live inside GoogleService-Info.plist.

Is it still possible to do what I did in the old way? Or is there another recommended way to achieve that?

解决方案

Well, I found the answer anyway. Instead of the usual setup, you'll have to initialize the app manually like so:

let firOptions = FIROptions(googleAppID: googleAppID, bundleID: bundleID, GCMSenderID: GCMSenderID, APIKey: nil, clientID: nil, trackingID: nil, androidClientID: nil, databaseURL: databaseURL, storageBucket: nil, deepLinkURLScheme: nil)        
FIRApp.configureWithOptions(firOptions)

let firebaseRef = FIRDatabase.database().reference()

You can name them too with configureWithName:options:
