如何在python的scrapy中启用cookiemiddleware [英] How to enable cookiemiddleware in scrapy in python

问题描述

在他们的文档中 http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#cookies-mw

他们告诉启用 cookie 中间件，但我无法找到如何执行此操作以及为此编辑哪个文件.谁能告诉我我该怎么做

They told to enable the cookie middle , but i am not able to find how to do that and which file to edit for that. Can anyone tell me how can i do that

推荐答案

update 会出现 cookie 默认在中间件中，所以只要 COOKIES_ENABLED = True 应该是充足的.如果中间件不是默认值的一部分，您只需要以下...

update it would appear cookies are in the middleware by default, so just COOKIES_ENABLED = True should be sufficient. You only need the below if the middleware is not part of the defaults...

据我从 doc.scrapy.org/en/latest/topics/downloader-middleware.html 中得知，您添加'scrapy.contrib.downloadermiddleware.cookies.CookiesMiddleware' 到带有相关顺序的 DOWNLOADER_MIDDLEWARE:

From what I can tell from doc.scrapy.org/en/latest/topics/downloader-middleware.html you add 'scrapy.contrib.downloadermiddleware.cookies.CookiesMiddleware' to DOWNLOADER_MIDDLEWARE with a relevant ordering:

要激活下载器中间件组件，请将其添加到DOWNLOADER_MIDDLEWARES 设置，这是一个字典，其键是中间件类路径及其值是中间件顺序.

To activate a downloader middleware component, add it to the DOWNLOADER_MIDDLEWARES setting, which is a dict whose keys are the middleware class paths and their values are the middleware orders.

DOWNLOADER_MIDDLEWARES = {
    'myproject.middlewares.CustomDownloaderMiddleware': 543,
    'scrapy.contrib.downloadermiddleware.cookies.CookiesMiddleware': 700 # <-
}

700 来自 http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#built-in-downloader-middleware-reference然后将 COOKIES_ENABLED = True(以及可选的 COOKIES_DEBUG = True)与您的其余设置放在一起.

The 700 comes from the default DOWNLOADER_MIDDLEWARES_BASE at http://doc.scrapy.org/en/latest/topics/downloader-middleware.html#built-in-downloader-middleware-reference Then put COOKIES_ENABLED = True (and optionally COOKIES_DEBUG = True) with the rest of your settings.
