requests.exceptions.SSLError: [Errno 1] _ssl.c:504: error:14090086:SSL routines: SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

今天使用requests 请求https 站点下载东西时报错SSL，发现可通过在requests.get()中增加参数verify=False来解决。

>>> url = "https://heartconnect.bostonscientific.com/client/latest/HeartConnectInstaller.EXE"

>>> r = requests.get(url)
