我试图使用模块套接字创建一个简单的客户端/服务器程序。这是每个标准套接字实现的基本教程。

#Some Error in sock.accept (line 13) --> no fix yet\nimport socket\nimport sys\n\nserversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)\nhost = socket.gethostname()\n\nprint >>sys.stderr, \'starting up on %s\' % host\nserversocket.bind((host, 9999))\nserversocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)\n\n#listening for incoming connections\nwhile True:\n    # Wait for a connection\n    print >>sys.stderr, \'waiting for a connection\'\n    connection , client_address = serversocket.accept()\n    try:\n        print >>sys.stderr, \'connection from\', client_address\n        #Receive data in small chunks and retransmit it\n        while True:\n            data = connection.recv(16)\n            print >>sys.stderr,\'received "%s"\' % data\n            if data:\n                print >>sys.stderr, \'sending data back …

我正在尝试使用winsock2 编写一个简单的服务器。我无法正确编译。
