    [E 171009 20:37:58 base_handler:203] HTTP 599: SSL certificate problem: unable to get local issuer certificate

Exclusion process

• 1. Updating pyspider (using the latest version) still has this problem
• 2. There are still problems with using the code validate_cert= false.

•               self.crawl(it.href, validate_cert = False)

Then check the error message carefully:

    File "d:\python\python35\lib\site-packages\tornado\concurrent.py", line 238, in result
    raise_exc_info(self._exc_info)

A similar scenario is described:

1. download http://curl.haxx.se/ca/cacert.pem
2. Error the file into the above directory: d: python python35 lib site-packages Tornado
3. Problem solving.
