在React.js中获取接口拉取数据后加载组件

import React, { Component } from 'react';

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

  componentDidMount() {
    fetch('https://api.example.com/data') // 替换为实际的接口地址
      .then(response => {
        if (response.ok) {
          return response.json();
        } else {
          throw new Error('Error fetching data');
        }
      })
      .then(data => {
        this.setState({ data: data, isLoading: false });
      })
      .catch(error => {
        this.setState({ error: error, isLoading: false });
      });
  }

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

    if (isLoading) {
      return <div>Loading...</div>;
    }

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

    return (
      <div>
        {/* 使用获取到的数据渲染组件 */}
        <h1>{data.title}</h1>
        <p>{data.description}</p>
      </div>
    );
  }
}

export default MyComponent;
