Swift 在iOS 11和iOS 12上注销后出现ASWebAuthentication和SFAuthentication登录问题，无法使会话无效

我正在使用

ASWebAuthentication和SFAuthentication

在OAuth2服务器上使用

grant\u type:authentication\u code

进行身份验证

除了以下各项外，一切都很完美：

用户登录成功

通过

注销访问令牌和状态代码为200的刷新令牌注销

测试撤销是否有效

 print("Auth-Login : Process: Authenticate user")
    let state = String().createState(length: 4)
    let codeVerifier = String().createCodeVerifier()
    let codeChallenge = codeVerifier.pkceEncode.base64UriEncode
    let parameters = ["state=\(state)", "code_challenge=\(codeChallenge)"]
    let url = createUrl(parameters: parameters)
    guard let authURL = url else { return }
    DispatchQueue.main.async {
        self.delegate?.removeLoader()
        if #available(iOS 12.0, *) {
            print("Auth-Login : Process: Run ASWebAuthenticationSession")

            self.webAuthSession = ASWebAuthenticationSession(url: authURL, callbackURLScheme: "no.bilkollektivet.app") { (callbackUrl, error) in
                print(callbackUrl)
                if let error = error {
                    completionHandler(nil, nil, error)
                } else {
                    let result = self.getCodeFromCallbackUrl(url: callbackUrl, state: state)
                    completionHandler(result.code, codeVerifier, result.error)
                }
            }
            if #available(iOS 13.0, *) {
                self.webAuthSession.presentationContextProvider = self
                self.webAuthSession.prefersEphemeralWebBrowserSession = true
            }

            self.webAuthSession.start()
        } else {
            print("Auth-Login : Process: Run SFAuthenticationSession")

            self.sfAuthSession = SFAuthenticationSession(url: authURL, callbackURLScheme: "no.bilkollektivet.app") { (callbackUrl, error) in
                if let error = error {
                    completionHandler(nil, nil, error)
                } else {
                    let result = self.getCodeFromCallbackUrl(url: callbackUrl, state: state)
                    completionHandler(result.code, codeVerifier, result.error)
                }
            }

            self.sfAuthSession.start()
        }
    }
