如何传递多个参数(request +2另一个参数)

// 使用fetch API发送GET请求，包含查询字符串参数
fetch('https://example.com/api?param1=value1&param2=value2')
  .then(response => response.json())
  .then(data => console.log(data));

// 使用fetch API发送POST请求，包含请求体参数
fetch('https://example.com/api', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    param1: 'value1',
    param2: 'value2'
  })
})
.then(response => response.json())
.then(data => console.log(data));

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

// 处理GET请求，获取查询字符串参数
app.get('/api', (req, res) => {
  const param1 = req.query.param1;
  const param2 = req.query.param2;
  res.json({ param1, param2 });
});

// 处理POST请求，获取请求体参数
app.use(express.json()); // 解析JSON请求体
app.post('/api', (req, res) => {
  const param1 = req.body.param1;
  const param2 = req.body.param2;
  res.json({ param1, param2 });
});

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