如何在React按钮中显示来自API的数据

import React, { Component } from 'react';

class DataButton extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: null
    };
  }

  componentDidMount() {
    fetch('https://api.example.com/data') // 替换为实际的API地址
      .then(response => response.json())
      .then(data => this.setState({ data }))
      .catch(error => console.log(error));
  }

  handleClick = () => {
    // 处理按钮点击事件
    // 可以重新获取API数据或处理数据
  }

  render() {
    const { data } = this.state;

    return (
      <div>
        <button onClick={this.handleClick}>点击获取数据</button>
        {data && <p>{data}</p>}
      </div>
    );
  }
}

export default DataButton;
