ZeroMQ - 三種模型的python實現

ZeroMQ是一個消息隊列網絡庫，實現網絡常用技術封裝。在C/S中實現了三種模式，這段時間用python簡單實現了一下，感覺python雖然靈活。但是數據處理不如C++自由靈活。

 

1.Request-Reply模式：

客戶端在請求後，服務端必須迴響應

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:

廣播所有client，沒有隊列緩存，斷開連接數據將永遠丟失。client可以進行數據過濾。

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：

由三部分組成，push進行數據推送，work進行數據緩存，pull進行數據競爭獲取處理。區別於Publish-Subscribe存在一個數據緩存和處理負載。

當連接被斷開，數據不會丟失，重連後數據繼續發送到對端。

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(dat
