正则表达式匹配任何1级深度的网址

to match a URL that is 1 level deep

匹配深度为1级的URL

and a url (x)levels deep but under a specific directory

和url(x)级别深,但在特定目录下

How do I achieve this in regex?

我如何在正则表达式中实现这一目标?

I saw a regex solution from this question : Regular expression to match a URL with 6 or more levels

我从这个问题中看到了一个正则表达式解决方案:正则表达式匹配具有6个或更多级别的URL

But, I am unable to generate a working one for my 2 conditions above.

但是,我无法为上述两个条件生成一个有效的工作。

2 个解决方案

#1

Try this regex:

试试这个正则表达式:

^someserver.com/(\w+|specific(/\w+){n})$

Where n is x-1 from your question

其中n是你问题的x-1

If you need separate regex:

如果你需要单独的正则表达式:

For one level:

一个级别:

^someserver.com/\w+$

For x levels under specific:

对于特定的x级别:

^someserver.com/specific(/\w+){x-1}$

#2

what if you just split it..?

如果你把它分开怎么办?

string url = "*.com/questions";

if (url.Split('/').Length == 2) //check for one level
{
    System.Diagnostics.Trace.WriteLine("One Level");
}

if (url.Split('/')[0].ToLower() == "*.com") //check for base
{
    System.Diagnostics.Trace.WriteLine("Good base");
}

may need to handle http:// though

可能需要处理http://
