Python socket ConnectionResetError：[Errno 54]通过对等方重置连接vs socket.error：[Errno 104]通过对等方重置连接

Question

我在调试代码时遇到麻烦，因为我无法理解所引发的套接字错误。这是回溯。

ConnectionResetError: [Errno 54] Connection reset by peer

根据errno库，Errno 54是errno.EXFULL，在Python 3中，documentation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？以及为什么套接字使用connection reset by peer说明而不是exchange full引发错误。又或者两个错误errno.EXFULL和errno.ECONNRESET有何关系？

PS：我read errno 54可能与http代理有关（我在代码中使用了代理）。如果是这样，如何？

Answer 1

根据errno库，Errno 54为errno.EXFULL

您是否通过检查errno.errorcode[54]确定了？无论如何-此[[errno库可能有问题。您可以通过查看errno.h，例如，在系统上验证错误代码的含义。 G。借助gcc：

gcc -xc -imacros errno.h -Wp,-P -E <(echo ECONNRESET) 另外，Python documentation说：

要将数字错误代码转换为错误消息，请使用os.strerror（）。
很可能是系统上的错误号54是ECONNRESET，并且os.strerror(54)将证明这一点。
[现在您已验证os.strerror(54)返回'Exchange full'，我感到困惑，为什么错误号54和错误字符串Connection reset by peer不匹配。如果在具有strace或类似内容的系统上发生这种情况，我将进一步检查操作系统，通过在受影响的进程上使用strace -e network返回哪个错误。
关于您关于EXFULL的问题：其含义似乎与系统有关； e。 G。在Linux上，仅从内核中的少数几个地方返回EXFULL，当找不到可用的桥接器端口号时，唯一与网络相关的位置在br_if.c中，涉及网桥（其他位置在USB和SCSI驱动程序中）。 >
