统一身份认证系统与排行榜：打造安全高效的社区环境

# 导入必要的库

from flask import Flask, request, session

app = Flask(__name__)

# 假设这是我们的用户数据库

users = {

'user1': {'password': 'password1'},

'user2': {'password': 'password2'}

}

融合门户系统

@app.route('/login', methods=['POST'])

def login():

username = request.form['username']

password = request.form['password']

if username in users and users[username]['password'] == password:

session['username'] = username

return '登录成功'

else:

return '用户名或密码错误'

if __name__ == '__main__':

app.run()

# 导入必要的库

from collections import defaultdict

# 假设这是我们的活动日志

activity_log = defaultdict(int)

# 记录用户的活动

def log_activity(user):

activity_log[user] += 1

# 获取排行榜

def get_leaderboard():

return sorted(activity_log.items(), key=lambda x: x[1], reverse=True)
