python 使用epoll非同步處理多個用戶端的串連

標籤：python   epoll   select   linux   socket   

伺服器端：

#-*- coding:utf8 -*-import socketimport selectimport osaddress = "0.0.0.0"port = 10001sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)def main():     global address,port,sock     epoll = select.epoll()     #擷取建立好的sock的檔案描述符     fd = sock.fileno()     sock.bind((address,port))     sock_dict = {}     sock_dict[fd] = sock     #對該sock進行註冊     epoll.register(fd,select.EPOLLIN)     sock.listen(5)     while True:         events = epoll.poll(1)         for fileno,event in events:     #擷取到的檔案描述符和sock的相同就說明是一個新的串連             if fileno == fd:                 (client,address) = sock.accept()                 print address                 client.setblocking(0) #將新的串連進行註冊，用來接收訊息                 epoll.register(client.fileno(),select.EPOLLIN)                 sock_dict[client.fileno()] = client            elif event & select.EPOLLIN:                 print "fileno:",fileno                 data = sock_dict[fileno].recv(128)                 if data == '你好':                     print "Data:",data.decode('UTF-8')                     sock_dict[fileno].send("你好")                elif len(data) == 0:                     print "線路%d已下線"%fileno                     epoll.unregister(fileno)                else:                     print "Data:",dataif __name__ == '__main__':    main()
