Python socket errno 32 断管

[英]Python socket errno 32 broken pipe

I am trying to send a message over TCP/IP via python, the first message has been received but when I try to send another one it returns: "socket error32 broken pipe"我正在尝试通过 python 通过 TCP/IP 发送一条消息,第一条消息已收到,但是当我尝试发送另一条消息时它返回:“socket error32 broken pipe”

my code:我的代码:

import socket
from RPi import GPIO
from time import sleep

TCP_IP = '192.168.178.29'
TCP_PORT = 45335
BUFFER_SIZE = 1024
MESSAGE = "Hello, World!"

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))

clk = 17
dt = 18

GPIO.setmode(GPIO.BCM)
GPIO.setup(clk, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)
GPIO.setup(dt, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)

counter = 0
clkLastState = GPIO.input(clk)

try:
      while True:
            clkState = GPIO.input(clk)
            dtState = GPIO.input(dt)
            if clkState != clkLastState:
                    if dtState != clkState:
                            counter += 1
                    else:
                            counter -= 1
                    s.send(str(counter))
                    print counter
            clkLastState = clkState
            sleep(0.01)
finally:
    GPIO.cleanup()

I tried searching for this issue but I couldn't find a solution, the socket is still open when I try to send the second message.我尝试搜索此问题,但找不到解决方案,当我尝试发送第二条消息时,套接字仍然打开。 Does anyone have a solution for this?有人对此有解决方案吗?

maybe SIGPIPE error :也许是 SIGPIPE错误:

Your server process has received a SIGPIPE writing to a socket.您的服务器进程已收到写入套接字的 SIGPIPE。 This usually happens when you write to a socket fully closed on the other (client) side.当您写入在另一端(客户端)完全关闭的套接字时,通常会发生这种情况。 This might be happening when a client program doesn't wait till all the data from the server is received and simply closes a socket (using close function).当客户端程序不等到从服务器接收到所有数据并简单地关闭套接字(使用关闭函数)时,可能会发生这种情况。

In a C program you would normally try setting to ignore SIGPIPE signal or setting a dummy signal handler for it.在 C 程序中,您通常会尝试设置忽略 SIGPIPE 信号或为其设置虚拟信号处理程序。 In this case a simple error will be returned when writing to a closed socket.在这种情况下,写入关闭的套接字时将返回一个简单的错误。 In your case a python seems to throw an exception that can be handled as a premature disconnect of the client.在您的情况下,python 似乎抛出了一个异常,可以作为客户端过早断开连接来处理。
