使用带Firebase的OAuth问题通过Facebook登录(input_token中的App_id与Viewing App不匹配)

问题描述

我正在尝试通过Facebook登录，通过OAuth收集一些数据，然后使用该凭据登录到Firebase.但是，我遇到了一个问题(请参阅下面的日志).

I am trying to login through Facebook, collect some data over OAuth and then login to Firebase using the credential. I am however encountering an issue (please see logs below).

代码示例

@objc func signInWFB() {

    let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()

    fbLoginManager.logIn(withReadPermissions: ["email","user_birthday","user_gender"], from: self) { (result, error) -> Void in

        if (error == nil) {
            let fbloginresult : FBSDKLoginManagerLoginResult = result!
            if (result?.isCancelled)! {
                print(result ?? FBSDKLoginManagerLoginResult())
            } else if(fbloginresult.grantedPermissions.contains("email")) {
                if((FBSDKAccessToken.current()) != nil) {
                    FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email, birthday, gender"]).start( completionHandler: { (connection, result, error) -> Void in
                        if (error == nil) {
                            //everything works print the user data
                            print(result ?? AnyObject.self)

                            if let d = result as? [String:Any] {

                                // ALL GOOD UP TO HERE

                                let credential = FacebookAuthProvider.credential(withAccessToken: FBSDKAccessToken.current()!.tokenString)

                                Auth.auth().signIn(with: credential) { (authResult, error) in
                                    if let error = error {
                                        print(error) // ERROR HERE
                                        return
                                    }

                                    // ...
                                }
                            }
                        }
                    })
                }
            }
        }
    }
}
