Ich verwende Redux und NetInfo zur Verbindungserkennung des Managers während des Starts und bei allen Aktionen, bei denen die Verbindung wichtig ist.NetInfo-Berichte, die während des Starts verbunden sind, und dieselben Aktionen
import createOneShotMiddleware from 'redux-middleware-oneshot';
import { NetInfo } from 'react-native';
import { checkConnection } from '../actions/networkActions';
export const middleware = createOneShotMiddleware((dispatch) => {
const handle = (isConnected) => dispatch(checkConnection(isConnected));
NetInfo.isConnected.fetch().done(handle);
NetInfo.isConnected.addEventListener('change', handle);
});
Aktionen
import * as types from './actionTypes';
export function checkConnection(isConnected) {
return {
type: types.CHECK_CONNECTION,
isConnected: isConnected
};
}
Reducers
import { CHECK_CONNECTION } from '../actions/actionTypes';
const initialState = {
isConnected: false,
};
export default function network(state = initialState, action = {}) {
switch (action.type) {
case CHECK_CONNECTION:
return Object.assign({}, state, {isConnected: action.isConnected})
default:
return state;
}
}
App.js
import React, { Component } from 'react-native';
import { createStore, applyMiddleware, combineReducers } from 'redux';
import { middleware as netInfo } from './Middleware/redux-middleware-react-native-netinfo';
import { Provider } from 'react-redux';
import thunk from 'redux-thunk';
import createLogger from 'redux-logger'
import * as reducers from './reducers';
import NavigationScreen from './Containers/NavigationScreen';
const logger = createLogger()
const createStoreWithMiddleware = applyMiddleware(thunk, logger, netInfo)(createStore)
const reducer = combineReducers(reducers);
const store = createStoreWithMiddleware(reducer)
export default class App extends Component {
render() {
return (
<Provider store={store}>
<NavigationScreen />
</Provider>
);
}
}
Es funktioniert nicht und nicht den Zustand aktualisieren, irgendwelche Vorschläge?
