js向controller传值

// JavaScript
window.location.href = "/controller?param1=value1&param2=value2";

<!-- HTML -->
<form action="/controller" method="POST">
  <input type="text" name="param1" value="value1">
  <input type="text" name="param2" value="value2">
  <button type="submit">Submit</button>
</form>

// JavaScript (使用Fetch API)
fetch('/controller', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    param1: 'value1',
    param2: 'value2'
  })
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));

// 服务器端设置CORS头示例（Node.js）
app.use((req, res, next) => {
  res.header('Access-Control-Allow-Origin', '*');
  res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
  next();
});

// Controller (Node.js/Express示例)
app.post('/controller', (req, res) => {
  const data = req.body;
  console.log(data); // 输出: { param1: 'value1', param2: 'value2' }
  res.json({ success: true });
});
