使用PySpider 框架出現錯誤 HTTP 599: SSL certificate problem: unable to get local issuer certificate，如下

HTTP 599: SSL certificate problem: unable to get local issuer certificate 
[E 161018 21:56:36 base_handler:195] HTTP 599: SSL certificate problem: unable to get local issuer certificate 
Traceback (most recent call last):

 raise_for_status 
raise http_error 
HTTPError: HTTP 599: SSL certificate problem: unable to get local issuer certificate

原因：

因為https協議需要對證書進行驗證導致，對訪問https網路需要證書

解決方法：

在兩個抓取函式中 加入 不要檢驗證書: 

validate_cert=False

成功解決！
