Swift - 使用 Firebase 的 Facebook 身份验证发生 (INVALID_CREDENTIALS) 错误

Question

Facebook 登录没有问题，但 firebase 无法获取 Facebook 帐户详细信息。

1. 我已经检查了 Firebase 网站中 INVALID_CREDENTIALS 的含义
2. 我检查了 Facebook 应用 ID 和密码。
3. 我删除了所有 IP 白名单

构建后，它会显示:

Loged in

Login failed. Error Domain=FirebaseAuthentication Code=-11 "(Error Code: INVALID_CREDENTIALS) Invalid authentication credentials provided." UserInfo={details={"providerErrorInfo":{}}, NSLocalizedDescription=(Error Code: INVALID_CREDENTIALS) Invalid authentication credentials provided.}

@IBAction func loginWithFB(sender: AnyObject) {
    let facebookLogin = FBSDKLoginManager()
    //self.performSegueWithIdentifier("CurrentlyLoggedIn", sender: sender)
    facebookLogin.logInWithReadPermissions(["public_profile", "email", "user_friends"], fromViewController: self, handler: {(facebookResult, facebookError) -> Void in
        if facebookError != nil {
            print("Facebook login failed. Error \(facebookError)")
        } else if facebookResult.isCancelled {
            print("Facebook login was cancelled.")
        }else{
            print("Loged in")
            let accessToken = FBSDKAccessToken.currentAccessToken().tokenString
            
            DataService.dataService.BASE_REF.authWithOAuthProvider("facebook", token: accessToken, withCompletionBlock: {error, authData in
                if error != nil{
                    print("Login failed. \(error)")
                }else{
                    print("Logged in! \(authData)")
                }})
        }
    })

您可以在项目中检查这行代码。我认为你的完成处理程序触发了这种情况。下面的内容适用于我的项目。

  let facebookLogin = FBSDKLoginManager()

  facebookLogin.logInWithReadPermissions(["email"], fromViewController: self) { (facebookResult: FBSDKLoginManagerLoginResult!, facebookError: NSError!) in

        if facebookError == nil {
            if FBSDKAccessToken.currentAccessToken() == nil {
                print("FOUND NIL!")
            }
            else if(facebookResult.isCancelled) {
                print("Cancelled")
            }
            else {
                let accessToken = FBSDKAccessToken.currentAccessToken().tokenString
                print(accessToken)

                DataService.ds.REF_BASE.authWithOAuthProvider("facebook", token: accessToken, withCompletionBlock: {
                    error, authData in

                    if error != nil {
                        print("yes \(error)")
                    }
                    else {

                        print("Logged in! \(authData)")

                    }
                })

            }
        }

   }
