今天繼續(xù)往后讀了一點(diǎn)，進(jìn)度非常慢，可能是理解不深刻。先記錄下今天學(xué)到的一些東西
查閱了一下，unix套接字用于計(jì)算機(jī)內(nèi)部的交流。其地址是文件路徑 且需要在unix/linux下 我是在unbunta下實(shí)現(xiàn)的。代碼依舊來自《python標(biāo)準(zhǔn)庫》
import socketimport sysimport osserver_adress = './uds_socket'try: os.unlink(server_adress)except OSError: if os.path.exists(server_adress): raisesock = socket.socket(socket.AF_UNIX,socket.SOCK_STREAM)PRint >>sys.stderr,'starting up on %s' %server_adress sock.bind(server_adress)sock.listen(1)while True: print >>sys.stderr,'waiting for a connection' connection ,client_address = sock.accept() try: print >>sys.stderr,'connection from',client_address while True: data = connection.recv(16) print >>sys.stderr,'recived "%s"' %data if data: print >>sys.stderr,'sending data back to the client ' connection.sendall(data) else: print >>sys.stderr,'no data from %s'%client_address break finally: connection.close()下面是client端的 import socket import sys
sock = socket.socket(socket.AF_UNIX,socket.SOCK_STREAM)server_address = './uds_socket'print >>sys.stderr,'connecting to %s'%server_addresstry: sock.connect(server_address)except socket.error,msg: print >>sys.stderr,msg sys.exit(1)try: message = 'This is the message.It will be repeated.' print >>sys.stderr,'sending "%s"' %message sock.sendall(message) amount_received = 0 amount_expected = len(message) while amount_received < amount_expected: data = sock.recv(16) amount_received+=len(data) print >>sys.stderr,'received "%s"'%datafinally: sock.close()與之前的程序差異不大，很明顯發(fā)現(xiàn)遵循以下幾步 服務(wù)器： 1.先選擇所需服務(wù)的套接字，例如 sock = socket(socket.AF_INET,socket.SOCK_STREAM) 這個(gè)是tcp 2綁定 3監(jiān)聽 4創(chuàng)建連接 5關(guān)閉 客戶端： 1如上第一步 2連接 以上是最近總結(jié)的一些東西
