HTTP 599: SSL certificate problem: unable to get local issuer certificate错误

自己在用 PySpider 框架爬虫运行代码后时出现 HTTP 599: SSL certificate problem: unable to get local issuer certificate错误

完整报错信息：

HTTP 599: SSL certificate problem: unable to get local issuer certificate

报错截图：

错误原因：

这个错误会发生在请求 https 开头的网址，SSL 验证错误，证书有误。

解决方法：

使用 self.crawl(url, callback=self.index_page, validate_cert=False)

这个方法基本可以解决问题了。
