通过Mysql解析本机json

Question

我是本机反应的新手。我需要在我的react native主页中显示我的JSON，但是我不确定该怎么做。您对Json文件是否长有任何建议吗？我只想在替代列表视图中显示“ s_title”：“ hjkjhjk”，“ s_description”：“ jnkmjhnkl”

JSON


[{"fk_i_item_id":3,"fk_c_locale_code":"en_US","s_title":"hjkjhjk","s_description":"jnkmjhnkl"}]

我的React-Native主页面下面是我需要从Json文件读取的页面：

import * as WebBrowser from 'expo-web-browser';
import React from 'react';
import {
  Image,
  Platform,
  ScrollView,
  StyleSheet,
  Text,
  View,
  Button,
  Alert

} from 'react-native';

export default function HomeScreen() {
  return (
    <View style={styles.container}>
      <ScrollView
        style={styles.container}
        contentContainerStyle={styles.contentContainer}>
        <View style={styles.welcomeContainer}>
          <Image
            source={
              __DEV__
                ? require('../assets/images/robot-dev.png')
                : require('../assets/images/robot-prod.png')
            }
            style={styles.welcomeImage}
          />
        </View>

        <View style={styles.getStartedContainer}>
          <DevelopmentModeNotice />
          <View
            style={[styles.codeHighlightContainer, styles.homeScreenFilename]}>
              <Button
          onPress={test}
          title="get DB"
          color="#841584"
          accessibilityLabel="get more about this purple button"
        />
          </View>
        </View>
      </ScrollView>
    </View>
  );
}

HomeScreen.navigationOptions = {
  header: null,
};

function test(){
  fetch('http://***:3000/users')
    .then(response => response.json())
    .then(users => console.warn(users));
  //Alert.alert(response);
}

function DevelopmentModeNotice() {
  if (__DEV__) {
    const learnMoreButton = (
      <Text onPress={handleLearnMorePress} style={styles.helpLinkText}>
        About dp
      </Text>
    );
    return (
      <Text style={styles.developmentModeText}>

        You get more than three wishes ! {learnMoreButton}
      </Text>
    );
  }
}
function handleLearnMorePress() {
  WebBrowser.openBrowserAsync(
    'https://demandplace.com/'
  );
}
