我正在使用本机使用Drawer Navigator进行React native 0.62。当用户登录到应用程序时,我将auth api响应存储到redux存储中。登录后,我想在仪表板标题中显示登录的用户名,但是我无法在函数内部使用redux存储。尝试用钩子,但没有用。任何帮助或建议。先感谢您。 这是我的代码:
const GradientHeader = props => (
<View style={{ backgroundColor: 'transparent' }}>
<LinearGradient
colors={['#6CCFF6', '#596AB2']}
start={{ x: 0, y: 0 }} end={{ x: 1, y: 0 }}
>
<Header {...props} />
</LinearGradient>
</View>
)
const DashboardStackScreen = ({ navigation }) => {
return (
<DashboardStack.Navigator screenOptions={{
headerTitle: 'Good Morning, John', // i wanted to access the redux store here
header: props => <GradientHeader {...props} />,
headerLeft: () => (
<TouchableOpacity onPress={navigation.openDrawer} style={{padding: 20}}>
<Image source={require('../assets/images/menu_bar.png')} style={{width:18, height:12}}/>
</TouchableOpacity>
),
headerTransparent: true,
headerStyle: {
backgroundColor: 'transparent'
},
headerTintColor: '#fff',
headerTitleStyle: { fontFamily: 'OpenSans-SemiBold', fontSize: 20},
}}>
<DashboardStack.Screen name="Dashboard" component={Dashboard} />
</DashboardStack.Navigator>
);
}
const MainNavigator = ({navigation}) => {
return (
<Drawer.Navigator initialRouteName="Dashboard" drawerContent={(props) => <DrawerContent {...props} />} hideStatusBar={false} focused={true} labelStyle={{ fontSize: 14, fontFamily: 'OpenSans-SemiBold' }} drawerContentOptions={{ activeBackgroundColor: "#F1F1F1", activeTintColor: "#000000", inactiveTintColor: "#818181",itemStyle: { marginLeft:0, paddingHorizontal: 10, width:'100%', borderRadius: 0}}}
>
<Drawer.Screen name="Dashboard" component={DashboardStackScreen} options={{
drawerIcon: ({ focused, size }) => (
<Image source={require('../assets/images/dashboard.png')} style={{ height: 17.78, width: 16}} resizeMode="contain"/>
)
}}
/>
</Drawer.Navigator>
);
}
const mapStateToProps = state => {
return {
data: state
};
};
export default connect(mapStateToProps)(MainNavigator);
login.reducer.js 从“ ../utility/Constants”导入{AUTH_REQUEST,AUTH_SUCCESS,AUTH_FAILURE,SET_AUTH};
const INITIAL_STATE = { 用户:{}, 加载:false, 错误:'',// false isAuthorized:否 };
const login =(状态= INITIAL_STATE,操作)=> { 开关(action.type){ 情况AUTH_REQUEST: return Object.assign({},state,{ 加载:是的, 用户:{}, 错误:“,// false isAuthorized:否 }); 情况AUTH_SUCCESS: return Object.assign({},state,{ 用户:action.payload, 加载:false, 错误:“,// false isAuthorized:true }); 情况AUTH_FAILURE: return Object.assign({},state,{ 用户:{}, 错误:action.payload,// true, 加载:false, isAuthorized:否 }); 情况SET_AUTH: return Object.assign({},state,{ 错误:“,// true, 加载:false, }); 默认: 返回状态; } };
导出默认登录名;

如果您已使用Provider连接到商店,则可以使用props作为数据访问组件MainNavigator中的数据,因为mapStateToProps返回具有您状态的数据。
const MainNavigator = ({navigation, data}) => {
console.log('Redux store data', data);
return (
<Drawer.Navigator initialRouteName="Dashboard" drawerContent={(props) => <DrawerContent {...props} />} hideStatusBar={false} focused={true} labelStyle={{ fontSize: 14, fontFamily: 'OpenSans-SemiBold' }} drawerContentOptions={{ activeBackgroundColor: "#F1F1F1", activeTintColor: "#000000", inactiveTintColor: "#818181",itemStyle: { marginLeft:0, paddingHorizontal: 10, width:'100%', borderRadius: 0}}}
>
<Drawer.Screen name="Dashboard" component={DashboardStackScreen} options={{
drawerIcon: ({ focused, size }) => (
<Image source={require('../assets/images/dashboard.png')} style={{ height: 17.78, width: 16}} resizeMode="contain"/>
)
}}
/>
</Drawer.Navigator>
);
}

您可以使用props.data在要显示的组件中的任何位置使用,请尝试使用以下标题标题:props.data

我没有在我的DashboardScreenStack中使用mapStateToProps的存储值(该方法不起作用),而是直接从基于函数的组件中调用store.getState()。它可以根据需要为我服务。
