Python 套接字 Makefile 错误 I/O 对已关闭文件的操作
Python Socket Makefile Error I/O operation on closed file
我想使用 socket.makefile 方法而不是 socket.send 或 socket.recv 但我在关闭文件时遇到此错误 I/O 操作。
from socket import *
s = socket(AF_INET,SOCK_STREAM)
s.connect(('localhost',4321))
read = s.makefile('r',)
write = s.makefile('w')
def send(cmd):
# print(cmd)
write.write(cmd + '\n')
write.flush()
with s,read,write:
send('TEST')
send('LIST')
while True:
send("DONE")
data = read.readline()
if not data: break
item = data.strip()
if item == 'DONE':
break
elif item.startswith("--player-"):
print(f"player{item.split('--player-')[1]}")
print(f'item: {item}')
send('OTHER')
send("GGGGGGGG") #I want to send this part in another place .I dont want to in with s,read,write:
print(read.readline().strip())
提前感谢您的帮助。
with
语句有这样的行为:
with s,read,write:
# smth to do
# <--------------- s, read and write are closed here
因此在关闭的对象上调用后续发送。
您不需要使用 with
语句:
# ...
send('TEST')
send('LIST')
while True:
send("DONE")
data = read.readline()
if not data: break
item = data.strip()
if item == 'DONE':
break
elif item.startswith("--player-"):
print(f"player{item.split('--player-')[1]}")
print(f'item: {item}')
send('OTHER')
send("GGGGGGGG") # write is open here
print(read.readline().strip())
或者在另一个地方重新创建 write
和 read
文件。但同时,排除第一个with
中的sockets
,使socket不关闭
with read, write: # <-- s excluded
send('TEST')
send('LIST')
while True:
send("DONE")
data = read.readline()
if not data: break
item = data.strip()
if item == 'DONE':
break
elif item.startswith("--player-"):
print(f"player{item.split('--player-')[1]}")
print(f'item: {item}')
send('OTHER')
# ...
read = s.makefile('r', ) # <-- recreate files
write = s.makefile('w')
send("GGGGGGGG")
