Question

当您从Python Shell或命令行运行Scrapy程序时，您会在屏幕上打印项目，如下所示：

c:\Python27\webscraper2\webscraper2>scrapy crawl mrcrawl2
2014-08-28 00:12:21+0100 [scrapy] INFO: Scrapy 0.24.4 started (bot: webscraper2)

2014-08-28 00:12:21+0100 [mrcrawl2] DEBUG: Crawled (200) <GET http://www.whoscored.com> (referer: None)

有没有办法禁用正在打印到屏幕上尚未从网页上删除的内容？理想情况下，如果响应不在200-300范围内，我只希望“DEBUG：Crawled”行打印到屏幕。

我曾尝试在Google上寻找答案，但我不确定要搜索什么。

使用-L WARNING选项将loglevel设置为WARNING：

scrapy crawl mrcrawl2 -L WARNING

只有在出现问题时才会打印消息。

使用Scrapy阻止不需要的项目打印到屏幕的方法
