▌1. 问题简述
[E 171009 20:37:58 base_handler:203] HTTP 599: SSL certificate problem: unable to get local issuer certificate

Exception: HTTP 599: SSL certificate problem: unable to get local issuer certificate▌2. 排除过程
- 更新pyspider（使用最新版本），仍存在该问题
- 使用代码 validate_cert =false 仍存在给问题；
self.crawl(it.href, validate_cert = False)后仔细查看报错信息：
File "d:\python\python35\lib\site-packages\tornado\concurrent.py", line 238, in result
raise_exc_info(self._exc_info)后搜索得之： cURL error 60: SSL certificate problem: unable to get local issuer certificate
讲述了类似的场景：
- 下载 http://curl.haxx.se/ca/cacert.pem
- 将文件报错到上述目录：d:\python\python35\lib\site-packages\tornado\
- 问题解决。
