OSError: [Errno 107] Transport endpoint is not connected
提问by daltonfury42
I am trying to learn how to use sockets in python to communicate between two computers. Unfortunately I get this error when everything seem to be right:
我正在尝试学习如何在 python 中使用套接字在两台计算机之间进行通信。不幸的是，当一切似乎都正确时，我收到此错误：
OSError: [Errno 107] Transport endpoint is not connected
OSError: [Errno 107] 传输端点未连接
Upon googling, I found that this is because the connection may have dropped. But I run both the client and server side of the program in the same machine itself. I tried connecting again from the client end and I get this:
谷歌搜索后，我发现这是因为连接可能已断开。但是我在同一台机器上同时运行程序的客户端和服务器端。我尝试从客户端再次连接，我得到了这个：
OSError: [Errno 106] Transport endpoint is already connected
OSError: [Errno 106] 传输端点已连接
indicating that the previous connection is still intact. I am pretty confused as to what is happening and how to make it work. Here is a screenscreen shot which shows what I am trying to do and the problem:
表明之前的连接仍然完好无损。我对正在发生的事情以及如何使其发挥作用感到非常困惑。这是一个屏幕截图，显示了我正在尝试做的事情和问题：

I tested your code with a little change on python 3.5.0 and it works:
I think the trick is in sock.accept()method which returns a tuple:
我在 python 3.5.0 上做了一点改动测试了你的代码，它有效：我认为诀窍在于sock.accept()返回一个元组的方法：
socket.accept()Accept a connection. The socket must be bound to an address and listening for connections. The return value is a pair(conn, address) where conn is a new socket object usable to send and receive data on the connection, and address is the address bound to the socket on the other end of the connection.
socket.accept()接受一个连接。套接字必须绑定到一个地址并侦听连接。该返回值是一个对（康涅狄格州，地址），其中conn是一个新的套接字对象可用于在连接上发送和接收数据，和地址是绑定到插座上的连接的另一端的地址。
server
服务器
#server
>>> import socket
>>> sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> sock.bind(("localhost", 8081))
>>> sock.listen(2)
>>> conn, addr = sock.accept()
>>> data= conn.recv(1024).decode("ascii")
client:
客户：
#client
>>> import socket
>>> sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> sock.connect(("localhost",8081))
>>> sock.send("hi".encode())
2
>>> sock.send("hiiiiiii".encode())
8
>>> sock.send(("#"*1020).encode())
1020
