python 内置函数 new_Python httplib2 AttributeError:“内置函数”或“方法”对象没有属性“new”...

在 Python 中，内置函数 `new` 已经在 Python 3 中被移除了。如果你遇到了类似 `AttributeError: 'builtin_function_or_method' object has no attribute 'new'` 的错误，很可能是因为你使用了旧版本的代码，而该代码在 Python 3 中已经不再被支持。

如果你使用 `new` 函数来创建一个对象，可以考虑使用 Python 中的 `object.__new__()` 方法代替。例如，如果你要创建一个新的字符串对象，可以使用以下代码：

s = str.__new__(str)

另外，如果你使用的是 httplib2 模块，你可以检查一下你的代码是否有错误。因为 httplib2 模块并不会使用 `new` 函数或方法。可能是其他地方的问题导致了该错误的出现。

该错误信息显示在进行HTTP连接时发生错误。具体来说，发生了getaddrinfo失败的异常，导致建立新连接的过程失败。该异常发生在尝试进行对一个为'uem-uat.yun.hihonor.com'主机的80端口的HTTP连接时。该连接尝试在 '/uem-gateway/analytics-metrics/services/user-access-detail/access-list/1/10?t=1679290718262' 路径上获取访问列表。最终，该错误信息的发生导致代码验证进程无法完成。

urllib.error.URLError: <urlopen error [SSL: UNSUPPORTED_PROTOCOL] unsupported protocol (_ssl.c:1131)>signal_shutdown [atexit]

这个错误通常是由于使用的SSL/TLS版本与服务器不兼容所致。您可以尝试以下方法：

1. 确保您的Python版本和所使用的库都是最新的，因为这些问题在最新版本中可能已经得到解决。

2. 尝试更改SSL版本，您可以在代码中添加以下行来尝试使用TLSv1.2：

   import ssl
   ssl._create_default_https_context = ssl._create_unverified_context

3. 如果您使用的是Python 2.x，请尝试添加以下行：

   import httplib
   httplib.HTTPSConnection._protocol_version = ssl.PROTOCOL_TLSv1

4. 如果您使用的是Python 3.x，请尝试添加以下行：

   import http.client
   http.client.HTTPSConnection._preferred_ssl_protocol = ssl.PROTOCOL_TLSv1

如果上述方法都不起作用，您可以尝试使用其他的请求库，例如Requests库，来代替urllib库。
