python - 在 splinter 中强制使用 SSLv3 或 TLSV1

Question

我正在尝试访问 gateway.playneverwinter.com有碎片

from splinter import Browser

browser = Browser()
browser.visit('https://gateway.playneverwinter.com')

if browser.is_text_present('Neverwinter'):
    print("Yes, we made it to the entrance of the Prime Material Plane!")
else:
    print("Fumble")

browser.quit()

它失败了

 File "gateway_bot.py", line 10, in <module>
    browser.visit('https://gateway.playneverwinter.com')
  File "/usr/local/lib/python3.4/dist-packages/splinter/driver/webdriver/__init__.py", line 53, in visit

    self._sslobj.do_handshake()
  ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:598)

Firefox 能够毫无问题地连接和浏览该站点，非常困难。经过一些诊断

$ openssl s_client -connect gateway.playneverwinter.com:443               
CONNECTED(00000003)
139745006343840:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:177:

我发现它看起来像a fixed issue in OpenSSL并且强制 SSLv3 或 TLSv1 允许我连接(然后我可以使用 cURL 下载目标)例如任一个

openssl s_client -ssl3 -connect gateway.playneverwinter.com:443
openssl s_client -tls1 -connect gateway.playneverwinter.com:443

根据 OpenSSL ticket 中的评论，我预计问题出在服务器端，但由于我无权访问它，所以它毫无帮助。那么，为了快速修复，有没有办法强制 splinter 使用 SSLv3 或 TLSv1？

Answer 1

在研究之后，我能想到的唯一方法是进入 client.py 文件并更改其 ssl 内容的初始化。
