Python 調用request模塊訪問https網站報錯: Can't connect to HTTPS URL because the SSL module is not available。
環境：Anaconda3.
安裝Anaconda3，開發環境使用Anaconda3 自帶的Jupyter Notebook。 相關函數代碼示例如下：
import request
import base64
def GetJiraTickets():
jiraticketshtml='''<font color="blue",size="3">'''
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.
這個函數在Anaconda的Jupyter Notebook中運行正常，爲了方便調用，創建bat腳本，添加下面一行命令來執行該python 腳本：
C:\Anaconda3\python.exe C:\WorkSpace\PythonProgram\Deployment\CreateComplianceReport2.0.py
但雙擊運行該bat腳本時報告如下錯誤：

網上搜索大部分是Linux環境相關，有兩篇帖子提到是Anaconda自帶的SSL版本和系統的SSL版本不匹配導致的。很可能是系統自帶的SSL版本低。下載安裝最新版本的OpenSSL後問題解決。bat 腳本執行正常。
