ZeroMQ是一个消息队列网络库,实现网络常用技术封装。在C/S中实现了三种模式,这段时间用python简单实现了一下,感觉python虽然灵活。但是数据处理不如C++自由灵活。
1.Request-Reply模式:
客户端在请求后,服务端必须回响应
server:
1 #!/usr/bin/python
2 #-*-coding:utf-8-*-
3 import time
4 import zmq
5
6 context = zmq.Context()
7 socket = context.socket(zmq.REP)
8 socket.bind("tcp://*:5555")
9
10 while True:
11 message = socket.recv()
12 print message
13 #time.sleep(1)
14 socket.send("server response!")
client:
1 #!/usr/bin/python
2 #-*-coding:utf-8-*-
3
4 import zmq
5 import sys
6
7 context = zmq.Context()
8 socket = context.socket(zmq.REQ)
9 socket.connect("tcp://localhost:5555")
10
11 while(True):
12 data = raw_input("input your data:")
13 if data == 'q':
14 sys.exit()
15
16 socket.send(data)
17
18 response = socket.recv();
19 print response
2.Publish-Subscribe模式:
广播所有client,没有队列缓存,断开连接数据将永远丢失。client可以进行数据过滤。
server:
1 #!/usr/bin/python
2 #-*-coding:utf-8-*-
3
4 import zmq
5 context = zmq.Context()
6 socket = context.socket(zmq.PUB)
7 socket.bind("tcp://127.0.0.1:5000")
8 while True:
9 msg = raw_input('input your data:')
10 socket.send(msg)
client:
1 #!/usr/bin/python
2 #-*-coding:utf-8-*-
3
4 import time
5 import zmq
6 context = zmq.Context()
7 socket = context.socket(zmq.SUB)
8 socket.connect("tcp://127.0.0.1:5000")
9 socket.setsockopt(zmq.SUBSCRIBE,'')
10 while True:
11 print socket.recv()
3.Parallel Pipeline模式:
由三部分组成,push进行数据推送,work进行数据缓存,pull进行数据竞争获取处理。区别于Publish-Subscribe存在一个数据缓存和处理负载。
当连接被断开,数据不会丢失,重连后数据继续发送到对端。
server:
1 #!/usr/bin/python
2 #-*-coding:utf-8-*-
3
4 import zmq
5
6 context = zmq.Context()
7
8 socket = context.socket(zmq.PULL)
9 socket.bind('tcp://*:5558')
10
11 while True:
12 data = socket.recv()
13 print data
work:
1 #!/usr/bin/python
2 #-*-coding:utf-8-*-
3
4 import zmq
5
6 context = zmq.Context()
7
8 recive = context.socket(zmq.PULL)
9 recive.connect('tcp://127.0.0.1:5557')
10
11 sender = context.socket(zmq.PUSH)
12 sender.connect('tcp://127.0.0.1:5558')
13
14 while True:
15 data = recive.recv()
16 sender.send(data)
client:
1 #!/usr/bin/python
2 #-*-coding:utf-8-*-
3
4 import zmq
5 import time
6
7 context = zmq.Context()
8 socket = context.socket(zmq.PUSH)
9
10 socket.bind('tcp://*:5557')
11
12 while True:
13 data = raw_input('input your data:')
14 socket.send(data)
消息结构: 在每个消息buff前均会自带一个buff长度
