Python socket Connection reset error:[Errno 54]对等方重置连接vs socket。error:[Errno 104]p重置连接

Question

我调试代码时遇到问题，因为我无法理解引发的套接字错误。 这是回溯。

ConnectionResetError: [Errno 54] Connection reset by peer

根据errno库Errno 54是errno.EXFULL，在python 3 documentation中被解释为exchange full。

据我所知，Connection reset by peer是Errno 104，即errno.ECONNRESET。

那么errno.EXFULL是什么意思？为什么socket用connection reset by peer描述而不是exchange full来引发错误。或者这两个错误errno.EXFULL和errno.ECONNRESET有什么关系？

PS:I read认为errno 54可能与http代理有关（我在代码中使用代理）。如果是，怎么做？

Answer 1

您可以在项目中尝试此代码：

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

如果不起作用，请确保服务器打开TLSv1支持。

Answer 2

我试着用python在OKEX.com上使用WebSocket创建coin market，因为url是一个外部地址，我使用了我们提供的vpn服务，但它仍然可以工作。这是一个回溯代码。

from ws4py.client.threadedclient import WebSocketClient


class DummyClient(WebSocketClient):
    def opened(self):
      # self.send("{'event': 'addChannel', 'channel': 'ok_sub_futureusd_btc_ticker_this_week'}") #发送请求数据格式
         # self.send("www.baidu.com")
         self.send("{'event':'addChannel','channel':'ok_sub_spot_bch_btc_ticker'}")
    def closed(self, code, reason=None):
        print("Closed down", code, reason)

#服务器返回消息
    def received_message(self, m):
        print("recv:", m)


if __name__ == '__main__':

    try:
        # 服务器连接地址wss://real.okex.com:10440/websocket/okexapi
       # ws = DummyClient('wss://real.okcoin.cn:10440/websocket/okcoinapi', protocols=['chat'])
        ws = DummyClient('wss://real.okex.com:10440/websocket/okexapi', protocols=['chat'])
        ws.connect()
        #ws.send("my test...")
        ws.run_forever()
    except KeyboardInterrupt:
        ws.close()

According to the errno library Errno 54 is errno.EXFULL

你是通过检查errno.errorcode[54]来确定的吗？无论如何-这个库可能有问题。您可以通过查看errno.h来验证系统中错误代码的含义，例如，借助gcc：

gcc -xc -imacros errno.h -Wp,-P -E <(echo ECONNRESET)

另外，Pythondocumentation说：

To translate a numeric error code to an error message, use os.strerror().

很可能系统上的错误号54是ECONNRESET，并且os.strerror(54)将证明这一点。

既然您已经验证了os.strerror(54)返回“Exchange full”，我很困惑为什么错误号54和错误字符串Connection reset by peer不匹配。如果这发生在具有strace或类似内容的系统上，我将进一步检查操作系统通过对受影响进程使用strace -e network返回的错误。

关于您关于EXFULL的问题：它的含义似乎有些依赖于系统；例如，在Linux上，EXFULL只从内核中的少数几个地方返回，唯一与网络相关的地方是在br_if.c有关网络桥的地方，当找不到可用的桥端口号时（其他地方在USB和SCSI驱动程序中）。
