我在尝试测试scrapy安装时遇到错误：

版本：

Scrapy 0.12.0.2536
Python 2.6.6
操作系统：Ubuntu 10.10

编辑：我可以使用我的浏览器，wget，telnet google.es 80来实现它，并且它会在所有网站上发生。

Answer 1

任务1： Scrapy会发送一个带有'bot'的usergent。网站也可能会根据用户代理进行阻止。

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：尝试在请求之间给出延迟，以欺骗人发送请求。

DOWNLOAD_DELAY = 0.25

任务3：如果无效，请安装wireshark并查看请求标头（或）发布数据的差异 scrapy发送时以及浏览器发送时。

Answer 2

您的网络连接可能存在问题。

首先，检查您的互联网连接。

如果您通过代理服务器访问网络，您应该将一段代码放入您的scrapy项目中（http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#scrapy.contrib.downloadermiddleware.httpproxy.HttpProxyMiddleware）

无论如何，请尝试升级您的scrapy版本。

Answer 3

我也遇到了这个错误。原来是我访问的端口被防火墙阻止了。我的服务器默认情况下会阻止端口，除非将其列入白名单。

Scrapy：连接被拒绝
