react本机映像uri和异步存储

import React from 'react';
import { Image } from 'react-native';

const MyComponent = () => {
  return (
    <Image
      source={require('./path/to/image.png')}
      style={{ width: 200, height: 200 }}
    />
  );
};

export default MyComponent;

// 定义异步请求的Action
const fetchData = () => {
  return async (dispatch) => {
    dispatch({ type: 'FETCH_DATA_REQUEST' });

    try {
      const response = await fetch('https://api.example.com/data');
      const data = await response.json();

      dispatch({ type: 'FETCH_DATA_SUCCESS', payload: data });
    } catch (error) {
      dispatch({ type: 'FETCH_DATA_FAILURE', payload: error.message });
    }
  };
};

// 定义Reducer处理异步请求的状态
const initialState = {
  loading: false,
  data: null,
  error: null,
};

const dataReducer = (state = initialState, action) => {
  switch (action.type) {
    case 'FETCH_DATA_REQUEST':
      return { ...state, loading: true };
    case 'FETCH_DATA_SUCCESS':
      return { ...state, loading: false, data: action.payload };
    case 'FETCH_DATA_FAILURE':
      return { ...state, loading: false, error: action.payload };
    default:
      return state;
  }
};

export default dataReducer;
