在了解firefly的客户端和服务器通信之前，个人觉得应该了解python的socket的编程，于是稍微了解了一下，大家都知道python是由C实现，所以大家很多会发现python 的socket编程，与C编程很雷同。

client.py:

#coding:utf-8################################################################## client.py# Author     : # Version    : 1.0.0.0# Date       : 2014-07-13# Description: ##################################################################测试客户端与服务器连接import socket;import sys;#客户端socket编程流程：'''1. 创建 Socket2. 连接到远程服务器：connect3. 读写数据:recv/sendall'''if __name__ == "__main__":host = "127.0.0.1";port = 8877;addr = (host,port);##地址try:client = socket.socket(socket.AF_INET,socket.SOCK_STREAM);##TCP连接except socket.error,msg:print "socket create failed ! Error code:%d ! Error Msg:%s"%(msg[0],msg[1]);sys.exit();##连接try:client.connect(addr);except socket.error,msg:print "socket connect failed ! Error code:%d ! Error Msg:%s"%(msg[0],msg[1]);sys.exit();else:print "client connect server:" + host + " port:" + str(port) + "success";message = "test python";client.sendall(message);##发送mesrecv = client.recv(1024);##接受print mesrecv;##关闭socketclient.close();

server.py:

<pre name="code" class="python">#coding:utf-8################################################################## server.py# Author     : # Version    : 1.0.0.0# Date       : 2014-07-13# Description: ##################################################################测试服务器连接import socket;import sys;#服务器socket编程流程'''1. 创建 socket2. 绑定到一个地址和端口:bind3. 侦听进来的连接:listen4. 接受连接:accept5. 读写数据:recv/sendall'''if __name__ == "__main__":try:server = socket.socket(socket.AF_INET,socket.SOCK_STREAM);except socket.error,msg:print "socket create failed !
