Firebase Facebook登錄：請求中提供了無效的API密鑰

Question

試圖讓Facebook登錄與新的Firebase一起使用，但我一直收到此錯誤消息：「請求中提供了無效的API密鑰。」

 facebookLogin.logInWithReadPermissions(["public_profile", "email", "user_friends"], fromViewController: self) { (login, error) in 
     if error != nil { 
      print("Facebook login failed. Error \(error)") 
     } else if login.isCancelled { 
      print("Facebook login was cancelled.") 
     } else { 
      let accessToken = FBSDKAccessToken.currentAccessToken().tokenString 
      let credential = FIRFacebookAuthProvider.credentialWithAccessToken(accessToken) 

      if let user = FIRAuth.auth()?.currentUser { 
       user.linkWithCredential(credential) { (sup, error) in 
        if let error = error { 
         print(error.localizedDescription) 
         return 
        } 
       } 
      } else { 
       FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in 
        if let error = error { 
         // ERROR COMING FROM HERE 
         print(error.localizedDescription) 
         return 
        } 
       } 
      } 
     } 
    }

按照Google的指示：https://support.google.com/cloud/answer/6158862?hl=en獲取或創建iOS應用的API KEY。

然後，你需要抓住這個API KEY，並把它放在GoogleService-Info.plist中爲：

重點： API_KEY

值：該API密鑰你得到了。
