####  --GET请求参数-- 传递参数到 GET 请求中  ####
# 1. GET 传递查询字符串参数
# URL 进行 GET 请求: http://localhost:5000/users?name=John&age=30

# URL 进行 GET 请求: http://localhost:5000/users/John
@app.route('/users/<name>')

# 3. GET 传递多个路径参数
# URL 进行 GET 请求:http://localhost:5000/users/John/30
@app.route('/users/<name>/<age>')
