版本:

• Scrapy 0.12.0.2536
• Python 2.6.6
• 操作系统:Ubuntu 10.10

编辑:我可以通过我的浏览器,wget,telnet google.es 80与它达成它,它发生在所有网站上.

Answer 1

任务1:Scrapy会发送一个带有'bot'的紧急情况.站点也可能基于用户代理阻止.

尝试在settings.py中覆盖USER_AGENT

例如: USER_AGENT = 'Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.7'

任务2:尝试在请求之间延迟,欺骗人类发送请求.

DOWNLOAD_DELAY = 0.25 

任务3:如果无效,请安装wireshark,并在scrapy发送和浏览器发送时查看请求标题(或)发布数据的差异.
