如何在没有useEffect的React组件中使用异步等待

import React, { Component } from 'react';

class MyComponent extends Component {
  async fetchData() {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    return data;
  }

  componentDidMount() {
    this.fetchData().then((data) => {
      // 处理异步获取的数据
      console.log(data);
    }).catch((error) => {
      // 处理错误
      console.error(error);
    });
  }

  render() {
    return (
      <div>
        {/* 组件的内容 */}
      </div>
    );
  }
}

export default MyComponent;
