PySpider问题记录http599

问题简述

背景说明：

python版本 3.5.2

操作流程：

• 1.执行pyspider安装：

•   pip install pyspider
  

• 2.运行pyspider

•   pyspider all
  

• 3.打开浏览器进行任务配置

•   localhost:5000
  

• 4.新增并执行task

错误如下描述

    [E 171009 20:37:58 base_handler:203] HTTP 599: SSL certificate problem: unable to get local issuer certificate
Traceback (most recent call last):

    raise_exc_info(self._exc_info)
  File "<string>", line 4, in raise_exc_info
Exception: HTTP 599: SSL certificate problem: unable to get local issuer certificate

排除过程

• 1.更新pyspider（使用最新版本），仍存在该问题
• 2.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)

讲述了类似的场景：

1. 下载 http://curl.haxx.se/ca/cacert.pem
2. 将文件报错到上述目录：d:\python\python35\lib\site-packages\tornado\
3. 问题解决。
