code: def get_query_param_from_url(url):
      
      url_obj = urlsplit(url)
      query_dict = parse_qs(url_obj.query)
      
      return OrderedDict(query_dict)
docs: 从 url 中获取 query 参数字典
  
      :param:
          * url: (string) 需要获取参数字典的 url
  
      :return:
          * query_dict: (dict) query 参数的有序字典，字典的值为 query 值组成的列表
  
      举例如下::
  
          print('--- get_query_param_from_url demo---')
          url = 'http://localhost:8811/mytest?page_number=1&page_size=10'
          query_dict = get_query_param_from_url(url)
          print(query_dict['page_size'])
          print('---')
  
      执行结果::
  
          --- get_query_param_from_url demo---
          ['10']
          ---
