在html和nodejs中使用复选框

<input type="checkbox" id="option1" name="option1" value="option1">
<label for="option1">Option 1</label>

<input type="checkbox" id="option2" name="option2" value="option2">
<label for="option2">Option 2</label>

const express = require('express');
const app = express();

app.use(express.urlencoded({ extended: true }));

app.get('/', (req, res) => {
  res.send(`
    <form action="/" method="POST">
      <input type="checkbox" id="option1" name="option1" value="option1">
      <label for="option1">Option 1</label><br>

      <input type="checkbox" id="option2" name="option2" value="option2">
      <label for="option2">Option 2</label><br>

      <button type="submit">Submit</button>
    </form>
  `);
});

app.post('/', (req, res) => {
  const selectedOptions = req.body;
  console.log(selectedOptions); // 输出选中的复选框的值

  // 在这里处理选中的复选框的值

  res.send('Form submitted successfully');
});

app.listen(3000, () => {
  console.log('Server started on port 3000');
});
