大话踩坑
selectors单线程ser端的坑
- 先贴段完善后的代码
import selectors
import socket,time
sel = selectors.DefaultSelector()
def accept(sock, mask):
conn, addr = sock.accept() # Should be ready
# print('accepted:', conn, 'from:', addr)
conn.setblocking(0)
sel.register(conn, selectors.EVENT_READ, read)
def read(conn, mask):
info = conn.recv(1024) # Should be ready
# print(">>>>info : ", info)
if info:
# print('echoing', repr(info), 'to', conn)
# time.sleep(0.1)
conn.send(info) # Hope it won't block
# print("in zhe 1----------------")
else:
print('closing', conn)
sel.unregister(conn)
conn.close()
sock = socket.socket()
sock.bind(('', 7677))
sock.listen(5)
sock.setblocking(0)
sel.register(sock, selectors.EVENT_READ, accept)
*把刚才写写的sock注册到sel里，accept就是上个写的函数*
print("waiting...")
while 1:
try: #这个地方不缩进，啥情况？
events = sel.select() ## 默认阻塞，
for key, mask in events:
callback = key.data ## 回调调用accept
callback(key.fileobj, mask) ## key.fileobj就是一个socket链接
except Exception as e:
print(e)
sel.unregister(key.fileobj)
key.fileobj.close()
IE内核好像不好用！
