Python 禁用重试中间件

我在settings.py中对该行进行了注释，但它仍处于启用状态

DOWNLOADER_MIDDLEWARES = {  
       #'scrapy.downloadermiddlewares.retry.RetryMiddleware': 90,
       'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 110,
    }

在程序开始时，它加载了很多我没有启用的中间件

2019-08-09 10:43:37 [scrapy.middleware] INFO: Enabled downloader middlewares:
['scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware',
 'scrapy.downloadermiddlewares.httpauth.HttpAuthMiddleware',
 'scrapy.downloadermiddlewares.downloadtimeout.DownloadTimeoutMiddleware',
 'scrapy.downloadermiddlewares.defaultheaders.DefaultHeadersMiddleware',
 'scrapy.downloadermiddlewares.useragent.UserAgentMiddleware',
 'scrapy.downloadermiddlewares.retry.RetryMiddleware',
 'scrapy.downloadermiddlewares.redirect.MetaRefreshMiddleware',
 'scrapy.downloadermiddlewares.httpcompression.HttpCompressionMiddleware',
 'scrapy.downloadermiddlewares.redirect.RedirectMiddleware',
 'scrapy.downloadermiddlewares.stats.DownloaderStats']

我错过什么了吗？有没有办法禁用它？

根据文档，

下载程序\u中间件

。在后者中，默认情况下启用选项

scrapy.downloadermiddleware.httpproxy.RetryMiddleware

所以要么写

DOWNLOADER_MIDDLEWARES = {  
       'scrapy.downloadermiddlewares.retry.RetryMiddleware': None,
       #                                                     ^^^
       'scrapy.downloadermiddlewares.httpproxy.HttpProxyMiddleware': 110,
    }

或者查看

DOWNLOADER\u middleware\u BASE

。看
