Javascript 当身份验证失败时，React navigation将用户发送到初始路由，而不是登录路由

我有一个应用程序，它有一个

着陆屏幕

作为初始路线。如果用户想要登录，他们必须从

登录屏幕

导航到

登录屏幕

。 如果用户按下登录按钮，我会将

isauthentication

设置为true，显示加载视图。问题在于，如果身份验证失败，例如，当用户输入错误的电子邮件或密码时，加载后会返回到

登录屏幕，而不是
登录屏幕

身份验证堆栈：

const CreateAuthStack = () => (
  <AuthStack.Navigator
    screenOptions={{
      headerStyle: {
        backgroundColor: '#3c74db',
      },
      headerTintColor: '#fff',
      headerTitleStyle: {
        fontWeight: 'bold',
      },
    }}>
    <AuthStack.Screen
      name="Landing"
      component={LandingScreen}
      options={{headerShown: false}}
    />
    <AuthStack.Screen
      name="SignIn"
      component={SignInScreen}
      options={{title: 'Sign In'}}
    />
    <AuthStack.Screen name="Register" component={RegisterScreen} />
  </AuthStack.Navigator>
);

登录功能：

const signIn = (email, password) => {
  setAuthenticating(true);
  axios
    .post(url, data, headers)
    .then(function(response) {
      if (response.status === 200) {
        setAuthenticating(false);
        setUser(email);
        AsyncStorage.setItem('user', email);
      }
    })
    .catch(function(error) {
      if (error.response.status === 404) {
        setAuthenticating(false); // Goes to Landing page instead of staying on signin page
        alert('Email is incorrect');
      } else if (error.response.status === 401) {
        setAuthenticating(false); // Goes to Landing page instead of staying on signin page
        alert('Password is incorrect');
      }
    });
};

const signIn = (email, password) => {
  setAuthenticating(true);
  axios
    .post(url, data, headers)
    .then(function(response) {
      if (response.status === 200) {
        setAuthenticating(false);
        setUser(email);
        AsyncStorage.setItem('user', email);
      }
    })
    .catch(function(error) {
      if (error.response.status === 404) {
        setAuthenticating(false); // Goes to Landing page instead of staying on signin page
        alert('Email is incorrect');
      } else if (error.response.status === 401) {
        setAuthenticating(false); // Goes to Landing page instead of staying on signin page
        alert('Password is incorrect');
      }
    });
};
