Scrapy 错误 - HTTP 状态代码未处理或不允许

Question

我正在尝试运行蜘蛛，但有此日志：

    twisted.internet.error.CannotListenError: Couldn't listen on 127.0.0.1:6073: [Errno 48] Address already in use.

第一个错误开始出现在所有蜘蛛中，但其他蜘蛛仍然可以工作。该：“[Errno 48] 地址已在使用中。” 然后来了：

        self.port.stopListening()
    exceptions.AttributeError: TelnetConsole instance has no attribute 'port'

错误“exceptions.AttributeError: TelnetConsole instance has no attribute 'port'”对我来说是新的......不知道发生了什么，因为我所有其他网站的蜘蛛都运行良好。

谁能告诉我如何解决？

编辑：

重新启动后，此错误消失了。但是仍然无法用这个蜘蛛爬行......现在这里是日志：

这个“2015-05-15 15:46:56+0100 [theverge] DEBUG: Ignoring response http://www.theverge.com/reviews>: HTTP status code is not processed or not allowed”很奇怪，因为我使用的是 download_delay = 2 和上周我可以毫无问题地抓取该网站...会发生什么？

Answer 1

Address already in use 会建议在该端口上侦听其他东西，很可能您正在并行运行另一个蜘蛛？第二个错误只是第一个错误的结果，因为它没有正确实例化端口，现在找不到它来关闭它。

我建议重新启动以确保没有端口仍在使用，并且只运行一个蜘蛛以查看它是否正常工作。如果再次发生，您可以使用netstat 或类似工具调查哪个应用程序正在使用该端口。

更新：HTTP错误403 Forbidden很可能意味着您已被该网站禁止发出过多的请求。要解决此问题，请使用代理服务器。结帐Scrapy HttpProxyMiddleware。

Answer 2

修改你项目中的settings.py文件可能对403错误有帮助：

DOWNLOADER_MIDDLEWARES = {'scrapy.downloadermiddlewares.useragent.UserAgentMiddleware': None,}
