PHP和Vue.js开发安全性最佳实践：防止数据篡改

// PHP代码示例
$url = 'https://example.com/api';
$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded
",
        'method'  => 'POST',
        'content' => http_build_query($data),
        'verify_peer' => true
    )
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);

// Vue.js代码示例
axios.post('https://example.com/api', data, { 
    headers: { 
        'Content-Type': 'application/x-www-form-urlencoded' 
    },
    https:true
})
.then(response => {
    console.log(response);
})
.catch(error => {
    console.error(error);
});

// PHP代码示例
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->execute(array('username' => $username));
$user = $stmt->fetch();

// Vue.js代码示例
const sanitizedUsername = this.escapeSpecialChars(username);
const user = await axios.get('https://example.com/api/users/' + sanitizedUsername);

// 转义特殊字符函数
escapeSpecialChars(text) {
    return text.replace(/[-[]{}()*+?.,\^$|#s]/g, '\$&');
}

// PHP代码示例
use FirebaseJWTJWT;

$token = array(
    "user_id" => $user_id,
    "username" => $username
);
$jwt = JWT::encode($token, $secret_key);

// Vue.js代码示例
const token = localStorage.getItem('token');
axios.post('https://example.com/api/data', {
    data: data,
    token: token
})
.then(response => {
    console.log(response);
})
.catch(error => {
    console.error(error);
});
