#首先redis的List 相當於一個佇列,可以實現先進先出的規則
採用brpop 是因為當佇列中沒有的時候會被阻塞,直到佇列中有可彈出元素或等待逾時
key [value, value] key 代表List的名字, [value, ...] 是值
import random import threading import redis import config lock = threading.Lock() lock.acquire() lock.release() pool = redis.ConnectionPool(host=config.HOST, port=config.PORT, decode_responses=True, password=config.PASSWORD) r = redis.Redis(connection_pool=pool) # 客户往redis 中放数据 def fun1(redisObj): value = random.randint(0, 100) # 往ccc列表中存放 print("开始发送数据:", value) redisObj.lpush("print",str(value)) for i in range(100): threading.Thread(target=fun1, args=(r,)).start()
import redis import time import config pool = redis.ConnectionPool(host=config.HOST, port=config.PORT, decode_responses=True, password=config.PASSWORD) r = redis.Redis(connection_pool=pool) # 服务端不断的取 while True: value = r.brpop("print") time.sleep(2) print(value)
import redis import time import config def get_redis(): pool = redis.ConnectionPool(host=config.HOST, port=config.PORT, decode_responses=True, password=config.PASSWORD) r = redis.Redis(connection_pool=pool) return r # 服务端不断的取 r = get_redis() while True: try: value = r.brpop("print") time.sleep(2) print(value) except Exception as e: print("等待超时重连") r = get_redis()
