This does the job nicely:

blocks|key|1398029|text|为了稍微改进Alex+Martelli的响应，下面的代码不仅可以清除额外的斜杠，还可以保留尾随(结尾)斜杠，这有时会很有用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1398030|>>>+items+=+["http://www.website.com",+"/api",+"v2/"]

http://www.website.com/api/v2/|code-block|syntax|javascript|1398031|它并不容易阅读，而且不会清除多个额外的尾部斜杠。|1398032|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

To improve slightly over Alex Martelli's response, the following will not only cleanup extra slashes but also preserve trailing (ending) slashes, which can sometimes be useful :

<pre><code>&gt;&gt;&gt; items = ["http://www.website.com", "/api", "v2/"]
&gt;&gt;&gt; url = "/".join([(u.strip("/") if index + 1 &lt; len(items) else u.lstrip("/")) for index, u in enumerate(items)])
&gt;&gt;&gt; print(url)
http://www.website.com/api/v2/
</code></pre>

It's not as easy to read though, and won't cleanup multiple extra trailing slashes.

blocks|key|1182690|text|使用furl，pip+install+furl将会是：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1182691|+furl.furl('/media/path/').add(path='js/foo.js')|code-block|syntax|javascript|1182692|entityMap^0|7|G|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

Using furl, <code>pip install furl</code> it will be:

blocks|key|1398143|text|Rune+Kaagaard提供了一个很好的紧凑的解决方案，对我来说是有效的，我对此做了一点扩展：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1398144|def+urljoin(*args):

++++return+"/".join(map(lambda+x:+str(x).strip('/'),+args))+%2B+trailing_slash|code-block|syntax|javascript|1398145|这允许连接所有参数，而不考虑尾随和结束斜杠，同时保留最后一个斜杠(如果存在)。|1398146|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Rune Kaagaard provided a great and compact solution that worked for me, I expanded on it a little:

<pre class="lang-py prettyprint-override"><code>def urljoin(*args):
 trailing_slash = '/' if args[-1].endswith('/') else ''
 return "/".join(map(lambda x: str(x).strip('/'), args)) + trailing_slash
</code></pre>

This allows all arguments to be joined regardless of trailing and ending slashes while preserving the last slash if present.

I found things not to like about all the above solutions, so I came up with my own. This version makes sure parts are joined with a single slash and leaves leading and trailing slashes alone. No <code>pip install</code>, no <code>urllib.parse.urljoin</code> weirdness.

<pre><code>In [1]: from functools import reduce

In [2]: def join_slash(a, b):
 ...: return a.rstrip('/') + '/' + b.lstrip('/')
 ...:

In [3]: def urljoin(*args):
 ...: return reduce(join_slash, args) if args else ''
 ...:

In [4]: parts = ['https://foo-bar.quux.net', '/foo', 'bar', '/bat/', '/quux/']

In [5]: urljoin(*parts)
Out[5]: 'https://foo-bar.quux.net/foo/bar/bat/quux/'

In [6]: urljoin('https://quux.com/', '/path', 'to/file///', '//here/')
Out[6]: 'https://quux.com/path/to/file/here/'

In [7]: urljoin()
Out[7]: ''

In [8]: urljoin('//','beware', 'of/this///')
Out[8]: '/beware/of/this///'

In [9]: urljoin('/leading', 'and/', '/trailing/', 'slash/')
Out[9]: '/leading/and/trailing/slash/'

One liner:

For example, I want to join a prefix path to resource paths like /js/foo.js.

I want the resulting path to be relative to the root of the server. In the above example if the prefix was "media" I would want the result to be /media/js/foo.js.

os.path.join does this really well, but how it joins paths is OS dependent. In this case I know I am targeting the web, not the local file system.

Is there a best alternative when you are working with paths you know will be used in URLs? Will os.path.join work well enough? Should I just roll my own?

例如，我想将前缀路径加入到/js/foo.js这样的资源路径中。我希望得到的路径是相对于服务器根目录的。在上面的例子中，如果前缀是"media“，我希望结果是/media/js/foo.js。os.path.join在这方面做得很好，但它连接路径的方式取决于操作系统。在这种情况下，我知道我的目标是web，而不是本地文件...
