# 示例代码：使用参数化查询防止SQL注入
import sqlite3

def safe_query(db, user_id):
    conn = sqlite3.connect(db)
    cursor = conn.cursor()
    cursor.execute("SELECT * FROM users WHERE id=?", (user_id,))
    result = cursor.fetchall()
    conn.close()
    return result

<!-- 示例代码：使用HTML转义库 -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/escape-html/1.0.3/escape-html.min.js"></script>
<script>
    var userInput = "<img src=x onerror=alert('XSS')>";
    var safeOutput = escapeHtml(userInput);
    document.getElementById('output').innerHTML = safeOutput;

# 示例代码：基本身份验证检查
from flask import Flask, request, abort

app = Flask(__name__)

@app.route('/admin')
def admin_page():
    if not is_authenticated(request):
        abort(403)  # Forbidden
    return "Welcome to the admin page!"

def is_authenticated(req):
    # 实际实现应包含更复杂的逻辑，如会话验证或令牌检查
    return req.headers.get('Authorization') == 'Bearer valid_token'
