获取扫描二维码的用户信息主要涉及到以下几个基础概念:
以下是一个简单的示例,展示如何生成二维码并在后端处理用户信息:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Scan QR Code</title>
</head>
<body>
<h1>Scan the QR Code Below</h1>
<img src="https://api.qrserver.com/v1/create-qr-code/?size=150x150&data=https://yourdomain.com/submit?uid=12345" alt="QR Code">
<form id="infoForm" action="/submit" method="POST">
<input type="hidden" name="uid" value="12345">
<label for="name">Name:</label>
<input type="text" id="name" name="name" required>
<label for="email">Email:</label>
<input type="email" id="email" name="email" required>
<button type="submit">Submit</button>
</form>
</body>
</html>
const express = require('express');
const bodyParser = require('body-parser');
const app = express();
const port = 3000;
app.use(bodyParser.urlencoded({ extended: true }));
app.post('/submit', (req, res) => {
const { uid, name, email } = req.body;
// Save user information to database
console.log(`User Info: UID=${uid}, Name=${name}, Email=${email}`);
res.send('Thank you for your submission!');
});
app.listen(port, () => {
console.log(`Server running at http://localhost:${port}/`);
});
通过以上步骤和方法,可以有效实现获取扫描二维码的用户信息功能。
