在React最终表单提交时调用API

import React, { useState } from 'react';

const FormComponent = () => {
  const [formData, setFormData] = useState({ name: '', email: '' });

  const handleChange = (e) => {
    const { name, value } = e.target;
    setFormData({ ...formData, [name]: value });
  };

  const handleSubmit = async (e) => {
    e.preventDefault();

    // 数据验证和处理操作
    // ...

    // 发送表单数据到后端API
    try {
      const response = await fetch('/api/submit', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify(formData),
      });

      // 处理API的响应结果
      const data = await response.json();
      // 更新组件状态或执行其他操作
      // ...
    } catch (error) {
      // 处理请求错误
      // ...
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <input type="text" name="name" value={formData.name} onChange={handleChange} />
      <input type="email" name="email" value={formData.email} onChange={handleChange} />
      <button type="submit">提交</button>
    </form>
  );
};

export default FormComponent;
