python - 机械化 : SSL: CERTIFICATE_VERIFY_FAILED

Question

好吧，我正在尝试为我的旅馆 wifi 创建一个自动登录脚本，我需要登录到 wifi 才能获得网络访问权限。如果我连接到 wifi，该网页在本地网络上保持打开状态。我只需要访问该网页并在那里登录即可。所以我试图使用机械化登录。

这是 python 代码。

我现在只是想打印发件人。

import mechanize
br = mechanize.Browser()
br.set_handle_robots(False)
br.open("https://192.168.10.3/connect/PortalMain")
for f in br.forms():
    print f

我得到的错误是

Traceback (most recent call last):
  File "demo.py", line 4, in <module>
    br.open("https://192.168.10.3/connect/PortalMain")
  File "/usr/local/lib/python2.7/site-packages/mechanize/_mechanize.py", line 254, in open
    return self._mech_open(url_or_request, data, timeout=timeout)

    response = UserAgentBase.open(self, request, data)

Answer 1

该站点可能使用了自签名的SSL证书，您可以关闭SSL验证(尽管您应该首先了解安全风险)，在br.open()之前添加这段代码:

import ssl
try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    # Legacy Python that doesn't verify HTTPS certificates by default
    pass
else:
    # Handle target environment that doesn't support HTTPS verification
    ssl._create_default_https_context = _create_unverified_https_context

来源:Disable ssl certificate validation in mechanize

所以在你的情况下，代码最终会是:

import mechanize
import ssl

ssl._create_default_https_context = ssl._create_unverified_context
br = mechanize.Browser()
br.set_handle_robots(False)
br.open("https://192.168.10.3/connect/PortalMain")
for f in br.forms():
    print f

应该可以，但我还没有测试过。
