Windows环境中Python SSL异常：Can't connect to HTTPS URL because the SSL module is not available

Python 调用request模块访问https网站报错: Can't connect to HTTPS URL because the SSL module is not available。

环境：Anaconda3.

安装Anaconda3，开发环境使用Anaconda3 自带的Jupyter Notebook。 相关函数代码示例如下：

 

---

import request

import base64

def GetJiraTickets():
    jiraticketshtml=''''''
    url="https://www.baidu.com.cn"
    auth=base64.b64encode(b'username:password')
    auth=auth.decode('utf8')
    header = {
        "Accept": "application/json",
        "Content-Type": "application/json",
        "Authorization": 'Basic {}'.format(auth),
        "User-Agent" : "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:68.0) Gecko/20100101 Firefox/68.0"
    }

    response = requests.request("POST",url,data=None,headers=header)

    #print(response.status_code)

    return response.text.

这个函数在Anaconda的Jupyter Notebook中运行正常，为了方便调用，创建bat脚本，添加下面一行命令来执行该python 脚本：

C:\Anaconda3\python.exe C:\WorkSpace\PythonProgram\Deployment\CreateComplianceReport2.0.py 

但双击运行该bat脚本时报告如下错误：

网上搜索大部分是Linux环境相关，有两篇帖子提到是Anaconda自带的SSL版本和系统的SSL版本不匹配导致的。很可能是系统自带的SSL版本低。下载安装最新版本的OpenSSL后问题解决。bat 脚本执行正常。
