在Python中验证URL [英] Validating URLs in Python

问题描述

我一直在尝试找出验证URL的最佳方法是什么(特别是在Python中)，但实际上并没有找到答案.似乎没有一种已知的验证URL的方法，它取决于您认为可能需要验证哪些URL.同样，我发现很难找到一个易于阅读的URL结构标准.我确实找到了RFC 3986和3987，但它们包含的内容远不止其结构.

I've been trying to figure out what the best way to validate a URL is (specifically in Python) but haven't really been able to find an answer. It seems like there isn't one known way to validate a URL, and it depends on what URLs you think you may need to validate. As well, I found it difficult to find an easy to read standard for URL structure. I did find the RFCs 3986 and 3987, but they contain much more than just how it is structured.

我是否缺少某些内容，或者没有一种标准的方法可以验证URL?

Am I missing something, or is there no one standard way to validate a URL?

推荐答案

这可能与您应该能够使用此处描述的urlparse库.

You should be able to use the urlparse library described there.

>>> from urllib.parse import urlparse # python2: from urlparse import urlparse
>>> urlparse('actually not a url')
ParseResult(scheme='', netloc='', path='actually not a url', params='', query='', fragment='')
>>> urlparse('http://google.com')
ParseResult(scheme='http', netloc='google.com', path='', params='', query='', fragment='')

在要检查的字符串上调用urlparse，然后确保ParseResult具有scheme和netloc

call urlparse on the string you want to check and then make sure that the ParseResult has attributes for scheme and netloc
