抑制'；SSL例程：SSL3_获取_服务器_证书：证书验证失败'；python中的错误

在python 2.7.5中使用pyVmomi时遇到问题。我在尝试从SDK运行示例脚本时遇到SSL证书错误。我尝试了帖子上提到的所有解决方案，但没有一个对我有效

下面是完整的控制台输出

看起来您正在使用自签名证书。通过

SmartConnect

连接时，请使用自己的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)

。。。或者使用已签名的ssl证书

这里有一些类似的问题（例如）。
