如何从postlist(posts.js)中获取Id并在react native中的post.js页面上显示

const posts = [
  { id: 1, title: 'Post 1', content: 'Lorem ipsum dolor sit amet' },
  { id: 2, title: 'Post 2', content: 'Lorem ipsum dolor sit amet' },
  // ...
];

import React from 'react';
import { View, Text, TouchableOpacity } from 'react-native';
import { useNavigation } from '@react-navigation/native';

const PostList = () => {
  const navigation = useNavigation();

  const handlePostPress = (postId) => {
    navigation.navigate('Post', { postId });
  };

  return (
    <View>
      {posts.map((post) => (
        <TouchableOpacity key={post.id} onPress={() => handlePostPress(post.id)}>
          <Text>{post.title}</Text>
        </TouchableOpacity>
      ))}
    </View>
  );
};

export default PostList;

import React from 'react';
import { View, Text } from 'react-native';
import { useRoute } from '@react-navigation/native';

const Post = () => {
  const route = useRoute();
  const { postId } = route.params;

  // 根据postId查找对应的帖子数据
  const post = posts.find((post) => post.id === postId);

  return (
    <View>
      <Text>{post.title}</Text>
      <Text>{post.content}</Text>
    </View>
  );
};

export default Post;
