如何将查询字符串映射到列表字典

def parse_query_string(query_string):
    query_params = {}
    for param in query_string.split('&'):
        key, value = param.split('=')
        if key in query_params:
            if isinstance(query_params[key], list):
                query_params[key].append(value)
            else:
                query_params[key] = [query_params[key], value]
        else:
            query_params[key] = value
    return query_params

def map_query_string_to_dict(query_string):
    query_params = parse_query_string(query_string)
    dict_list = []
    for key, value in query_params.items():
        if isinstance(value, list):
            for val in value:
                dict_list.append({key: val})
        else:
            dict_list.append({key: value})
    return dict_list

# 示例用法
query_string = "name=John&age=25&hobby=reading&hobby=sports"
result = map_query_string_to_dict(query_string)
print(result)

[{'name': 'John'}, {'age': '25'}, {'hobby': 'reading'}, {'hobby': 'sports'}]
