将类组件重构成函数组件

const EventDetail = (props) => {
  // export default  class EventDetail extneds React.Component{
  const navigation = useNavigation();
  // static contextType = NavigationContext;
  // 点击返回事件列表页
  const goPage = () => {
    navigation.navigate("Home");
  };
  // goPage = () => {
  //   // 上边实现效果this.context===this.props.navigation
  //   this.context.navigate("Home");
  // };

  const [eventData, setEventData] = useState({});
  // state = {
  //   eventData: {},
  // };

  useEffect(() => {
    // 立即执行
    getEventDetail();
  }, []);
  // componentDidMount() {
  //   this.getEventDetail();
  // }
  const getEventDetail = async () => {
    const url = EVENT_DETAIL.replace(":id", props.route.params.id);
    // const url = EVENT_DETAIL.replace(":id", this.props.route.params.id);
    const res = await request.privateGet(url);
    setEventData(res.data.event);
    // this.setState({ eventData: res.data.event });
  };
  // render() {
