Regex -匹配URL中除特定单词之外的任何字符序列

I want to match a URL that contains any sequence of valid URL characters but not a particular word. The URL in question http://gateway.ovid.com and I want to match anything but the word 'gateway' so:

我希望匹配一个URL，该URL包含任何有效的URL字符序列，但不包含特定的单词。问题中的URL http://gateway.ovid.com和我想匹配除“gateway”这个词之外的任何东西:

http://abc123.ovid.com - would match
http://abc123.ovid.com将匹配
http://abc.123.ovid.com - would match
http://abc.123.ovid.com将匹配
http://abc-123.ovid.com - would match
http://abc - 123. - ovid.com,将匹配
http://fdfsffdfs.ovid.com - would match
http://fdfsffdfs.ovid.com将匹配

but

但

http://gateway.ovid.com - would NOT match
http://gateway.ovid.com -不匹配

Something like the following:

像下面这样:

^http://([a-z0-9\-\.]+|(?<!gateway))\.ovid\.com$

but it doesn't seem to work.

但这似乎行不通。

Update: Sorry forget to mention the language, it's C#.NET

更新:抱歉忘了提到语言，它是c#。net

Your regex is almost correct except the extra '|' after '+'. Remove the '|'

您的regex几乎是正确的，除了+后面的额外的“|”。删除“|”

^http://([a-z0-9\-\.]+(?<!gateway))\.ovid\.com$

You didn't specify host language, but why not something like this psuedocode

您没有指定主机语言，但是为什么不指定这个psuedocode

bool good = Regex.Match( yourRegex ) and not Regex.Match(gateway)
