如何将处于react组件状态的字符串传递给外部python文件

import React, { useState } from 'react';

function MyComponent() {
  const [myString, setMyString] = useState('');

  // 其他组件代码...

  return (
    <div>
      {/* 在组件中显示字符串 */}
      <p>{myString}</p>
    </div>
  );
}

export default MyComponent;

import React, { useState } from 'react';
import axios from 'axios';

function MyComponent() {
  const [myString, setMyString] = useState('');

  const sendDataToPython = () => {
    axios.post('/api/sendData', { data: myString })
      .then(response => {
        // 处理响应
      })
      .catch(error => {
        // 处理错误
      });
  };

  // 其他组件代码...

  return (
    <div>
      {/* 在组件中显示字符串 */}
      <p>{myString}</p>

      {/* 按钮用于将数据发送给Python文件 */}
      <button onClick={sendDataToPython}>发送数据</button>
    </div>
  );
}

export default MyComponent;

from flask import Flask, request

app = Flask(__name__)

@app.route('/api/sendData', methods=['POST'])
def receive_data():
    data = request.json['data']
    
    # 在这里处理接收到的数据
    # ...

    return '数据已接收'

if __name__ == '__main__':
    app.run()
