SSL：APPLICATION_DATA_AFTER_CLOSE_NOTIFY 错误

编程问答 2022-05-31

问题描述

我使用 tor 的 http 代理（使用 aiohttp_socks）使用 aiohttp 发送多个请求

完成一些请求后，我收到以下错误：

Traceback (most recent call last):
  File "main.py",line 171,in <module>
    loop.run_until_complete(future)
  File "/usr/lib/python3.8/asyncio/base_events.py",line 616,in run_until_complete
    return future.result()
  File "main.py",line 95,in get_market_pages
    async with session.get(active_link,headers=headers) as response:

    self._resp = await self._coro

    await resp.start(conn)

    await self._waiter
aiohttp.client_exceptions.ClientOSError: [Errno 1] [SSL: APPLICATION_DATA_AFTER_CLOSE_NOTIFY] application data after close notify (_ssl.c:2745)

我找不到关于此错误的任何信息，除了关于类似错误的 git 讨论 - github

在那里我找到了一个解决方法 (link)，我可以修改它以忽略此错误，但它不起作用，错误仍然存​​在。

变通方法的修改版本：

SSL_PROTOCOLS = (asyncio.sslproto.SSLProtocol,)
try:
    import uvloop.loop
except ImportError:
    pass
else:
    SSL_PROTOCOLS = (*SSL_PROTOCOLS,uvloop.loop.SSLProtocol)

def ignore_aiohttp_ssl_eror(loop):
    """Ignore aiohttp #3535 / cpython #13548 issue with SSL data after close

    There is an issue in Python 3.7 up to 3.7.3 that over-reports a
    ssl.SSLError Fatal error (ssl.SSLError: [SSL: KRB5_S_INIT] application data
    after close notify (_ssl.c:2609)) after we are already done with the
    connection. See GitHub issues aio-libs/aiohttp#3535 and
    python/cpython#13548.

    Given a loop,this sets up an exception handler that ignores this specific
    exception,but passes everything else on to the prevIoUs exception handler
    this one replaces.

    Checks for fixed Python versions,disabling itself when running on 3.7.4+
    or 3.8.

    """

    orig_handler = loop.get_exception_handler()

    def ignore_ssl_error(loop,context):
        if context.get("message") in {
            "SSL error in data received","Fatal error on transport",}:
            # validate we have the right exception,transport and protocol
            exception = context.get('exception')
            protocol = context.get('protocol')
            if (
                isinstance(exception,ssl.SSLError)
                and exception.reason == 'APPLICATION_DATA_AFTER_CLOSE_NOTIFY'
                and isinstance(protocol,SSL_PROTOCOLS)
            ):
                if loop.get_debug():
                    asyncio.log.logger.debug('Ignoring asyncio SSL KRB5_S_INIT error')
                return
        if orig_handler is not None:
            orig_handler(loop,context)
        else:
            loop.default_exception_handler(context)

    loop.set_exception_handler(ignore_ssl_error)
