强制 Python Scrapy 不编码 URL [英] Force Python Scrapy not to encode URL

问题描述

有一些带有 [] 的 URL，比如

There are some URLs with [] in it like

http://www.website.com/CN.html?value_ids[]=33&value_ids[]=5007

但是当我尝试使用 Scrapy 抓取此 URL 时，它会向此 URL 发出请求

But when I try scraping this URL with Scrapy, it makes Request to this URL

http://www.website.com/CN.html?value_ids%5B%5D=33&value_ids%5B%5D=5007

如何强制scrapy不对我的URL进行urlenccode?

How can I force scrapy to not to urlenccode my URLs?

推荐答案

在创建 Request 对象时，scrapy 应用了一些 url 编码方法.要恢复这些，您可以使用自定义中间件并根据需要更改 url.

When creating a Request object scrapy applies some url encoding methods. To revert these you can utilize a custom middleware and change the url to your needs.

您可以像这样使用 Downloader Middleware:

class MyCustomDownloaderMiddleware(object):

    def process_request(self, request, spider):
        request._url = request.url.replace("%5B", "[", 2)
        request._url = request.url.replace("%5D", "]", 2)

不要忘记像这样激活"settings.py 中的中间件:

Don't forget to "activate" the middleware in settings.py like so:

DOWNLOADER_MIDDLEWARES = {
    'so.middlewares.MyCustomDownloaderMiddleware': 900,
}

我的项目名为 so，文件夹中有一个文件 middlewares.py.您需要根据您的环境进行调整.

My project is named so and in the folder there is a file middlewares.py. You need to adjust those to your environment.
