如何使用带有箭头函数的React State使用try catch处理错误

import React, { Component } from 'react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [],
      error: null
    };
  }

  // ...
}

import React, { Component } from 'react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [],
      error: null
    };
  }

  componentDidMount() {
    try {
      // 执行可能会出错的代码
      // 例如，发送异步请求获取数据
      const response = await fetch('https://api.example.com/data');
      const data = await response.json();
      this.setState({ data });
    } catch (error) {
      // 处理错误
      this.setState({ error });
    }
  }

  // ...
}

import React, { Component } from 'react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [],
      error: null
    };
  }

  componentDidMount() {
    try {
      // 执行可能会出错的代码
      // 例如，发送异步请求获取数据
      const response = await fetch('https://api.example.com/data');
      const data = await response.json();
      this.setState({ data });
    } catch (error) {
      // 处理错误
      this.setState({ error });
    }
  }

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

    if (error) {
      return <div>Error: {error.message}</div>;
    }

    return (
      <div>
        {/* 显示数据 */}
      </div>
    );
  }
}
