在python中抑制'SSL例程：SSL3_GET_SERVER_CERTIFICATE：证书验证失败'错误

Question

我在使用python 2.7.5的pyVmomi时遇到了麻烦。 尝试从SDK运行示例脚本时，我收到SSL证书错误。 我尝试了这篇文章中提到的所有解决方案，但没有一个对我有用。

以下是完整的控制台输出。

/usr/lib/python2.7/site-packages/requests/packages/urllib3/util/ssl_.py:315: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform.

看起来您正在使用自签名证书。 通过SmartConnect连接时，请使用您自己的sslContext并禁用证书验证。

from pyVim.connect import SmartConnect
import ssl

context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_NONE

si = SmartConnect(host=somehost.com, port=443, user=someone, pwd=secret, sslContext=context)

...或使用签名的ssl证书。
