• 将分布式-队列的实现交给redis


    import requests

    with open(f,'r',encoding='utf-8') as fr:
    for i in fr:
    try:

    #url_l.append(ii)
    rds.sadd('chk_url_all', ii)
    except Exception as e:
    print(e)


    去内存,持久化

    发布代码至多台机器





    redis 自典型 支持更新
    rds = return_redis(redis_key)
    rds.hset(my_dict_name, uid, uid_info)
