如何从 url 中删除查询? [英] How do I remove a query from a url?

问题描述

我正在使用scrapy 来抓取一个站点，该站点似乎在每个URL 末尾的查询字符串中附加了随机值.这将爬行变成了一种无限循环.

I am using scrapy to crawl a site which seems to be appending random values to the query string at the end of each URL. This is turning the crawl into a sort of an infinite loop.

如何让scrapy忽略URL的查询字符串部分?

How do i make scrapy to neglect the query string part of the URL's?

推荐答案

参见 urllib.urlparse

示例代码:

from urlparse import urlparse
o = urlparse('http://url.something.com/bla.html?querystring=stuff')

url_without_query_string = o.scheme + "://" + o.netloc + o.path

示例输出:

>>> url_without_query_string = o.scheme + "://" + o.netloc + o.path
>>> print url_without_query_string
http://url.something.com/bla.html
