如何在React中使用表单发出post请求

npm install axios

import axios from 'axios';

import React, { useState } from 'react';

function MyForm() {
  const [formData, setFormData] = useState({
    name: '',
    email: '',
    message: ''
  });

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

  const handleSubmit = (e) => {
    e.preventDefault();
    
    axios.post('/api/endpoint', formData)
      .then(response => {
        console.log(response);
        // 处理成功响应
      })
      .catch(error => {
        console.error(error);
        // 处理错误响应
      });
  };

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

function App() {
  return (
    <div className="App">
      <MyForm />
    </div>
  );
}
