Question

下面的代码片段：

s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM) 

MAX = 65535 
PORT = 6000 

if sys.argv[1:]==['server']: 
    s.bind(('127..0.0.1',PORT)) 
    print 'Listnening at ',s.getsockname() 
    while True: 
     data ,address = s.recvfrom(MAX) 
     s.sendto('Your data was %d bytes' %len(data),address) 
elif sys.argv[1:] == ['client']: 
    print 'Address before sending'.s.getsockname() 
    s.sendto('This is my message ',('127.0.0.1',PORT)) 
    print 'Address after sending ',s.getsockname() 
    data,address = s.recvfrom(MAX) 
    print 'The Server ',address,' says',repr(data) 

else: 
    print >>sys.stderr, 'Usage: udp_local.py server|client'

Answer 1

只需更换这行：

s.bind(('127..0.0.1',PORT)) 

与此：

s.bind(('127.0.0.1',PORT))
