如何从上下文中获取视图中对象的id？

import React from 'react';

class ObjectComponent extends React.Component {
  render() {
    const { objectId } = this.props;
    return (
      <div>
        <h1>Object ID: {objectId}</h1>
      </div>
    );
  }
}

const App = () => {
  return (
    <div>
      <ObjectComponent objectId="12345" />
    </div>
  );
};

export default App;

<template>
  <div>
    <h1>Object ID: {{ objectId }}</h1>
  </div>
</template>

<script>
export default {
  props: {
    objectId: String
  }
};
</script>

import { Component, Input } from '@angular/core';

@Component({
  selector: 'app-object',
  template: `
    <div>
      <h1>Object ID: {{ objectId }}</h1>
    </div>
  `
})
export class ObjectComponent {
  @Input() objectId: string;
}
