React Native - NavigationActions.navigate() 不在 redux 中导航

Question

我有两个导航器，一个是stackNavigator，另一个是drawerNavigator。 我想要做的是调度一个动作并且登录成功并将用户重定向到抽屉导航器。我使用了反应导航。 我所做的是在 saga 中发送动作登录成功。 使用NavigationActions.navigate({ routeName: 'drawerStack' }) 调度操作。 该操作成功调度，但它没有导航到drawerNavigator，如下图所示。我做错了什么？

saga.js

function* watchLoginRequest() {
  while (true) {
    const { state } = yield take(LOGIN_REQUEST);

    try {
      const payload = {
        state
      };
      const response = yield call(loginCall, payload);
      yield put(loginSuccess(response));
      yield setUser(response.user);
      yield put(NavigationActions.navigate({ routeName: 'drawerStack' }));
    } catch (err) {
      yield put(loginFailure(err.status));
    }
  }
}

drawerNavigation.js

// drawer stack
const DrawerStack = DrawerNavigator({
  testComponent: { screen: TestComponent },
});

const DrawerNav = StackNavigator({
  drawerStack: { screen: DrawerStack }
}, {
  headerMode: 'float',
  navigationOptions: ({ navigation }) => ({
    headerStyle: { backgroundColor: 'green' },
    title: 'Logged In to your app!',
    headerLeft: <Text onPress={() => navigation.navigate('DrawerOpen')}>Menu</Text>
  })
});

export default DrawerNav;

loginNavigation.js

// login stack
const LoginStack = StackNavigator({

  startScreen: { screen: StartScreen },
  loginScreen: { screen: LoginScreen },
  personalInformation: { screen: PersonalInformation },
  vehicleInformation: { screen: VehicleInformation },
  availability: { screen: Availability },
  selectRegisteration: { screen: SelectRegisteration },
  serviceAddress: { screen: ServiceAddress },

}, {
  headerMode: 'none',
  transitionConfig: TransitionConfiguration

});


export default LoginStack;

ReduxNavigation.js

class ReduxNavigation extends React.Component {
  constructor(props) {
    super(props);
    const { dispatch, nav } = props;
    const navigation = ReactNavigation.addNavigationHelpers({
      dispatch,
      state: nav
    });
    this.state = {
      loggedInStatus: false,
      checkedSignIn: false
    };
  }

  componentWillMount() {
    isSignedIn()
      .then(res => {
        if (res !== null) {
          this.setState({
            loggedInStatus: true,
            checkedSignIn: true
          });
        } else {
          console.log(res);
        }
      })
      .catch(err => console.log(err));
  }

  render() {
    return <LoginNavigation navigation={this.navigation} />;
  }
}

const mapStateToProps = state => ({ nav: state.nav });
export default connect(mapStateToProps)(ReduxNavigation);

要导航到TestComponent，您希望您的routeName 是testComponent，而不是抽屉堆栈。您导航到特定屏幕，而不是导航组件。
