以正确的格式将数据从react发送到节点

// 在React组件中
const sendData = async () => {
  const data = { name: 'John', age: 30 };

  try {
    const response = await fetch('http://your-node-server.com/api/data', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(data),
    });

    if (!response.ok) {
      throw new Error('Network response was not ok');
    }

    const result = await response.json();
    console.log('Success:', result);
  } catch (error) {
    console.error('Error:', error);
  }
};

// 调用函数
sendData();

// 首先安装axios：npm install axios
import axios from 'axios';

const sendData = async () => {
  const data = { name: 'John', age: 30 };

  try {
    const response = await axios.post('http://your-node-server.com/api/data', data);
    console.log('Success:', response.data);
  } catch (error) {
    console.error('Error:', error);
  }
};

// 调用函数
sendData();
