RegEx-Stylish-排除某些页面

Question

我正在尝试在用于浏览器的时尚插件上使用正则表达式来匹配网站。

此正则表达式需要匹配一个域（我们将其命名为website.com ）

这就是它应该如何工作的：

• 允许的任何子域
• http或https
• website.com/team* =>不允许
• website.com/forum* =>不允许
• website.com * =>允许

从某种意义上说，它应适用于网站的任何页面，但.com后立即与/ team或/ forum的任何链接均无效。

我尝试过

((\\w+)*\\.\\w{2,6})(\\/)(?!team|forum)([^\\s]+)

但这不起作用，我也不知道如何使其仅与域名website.com相匹配

另一个问题是，这种正则表达式对时尚用户有用吗？ 我在Google上找不到任何相关信息

Answer 1

\\w{2,6}与website不匹配，因为它包含7个字符。 末尾的字符类([^\\s]+将不与空格字符匹配，可以使用0+次的量词，并使用*进行匹配，当没有尾随的正斜杠时也可以匹配。

如果要匹配website.com，也可以匹配.com部分，否则[^\\s]*将匹配其余的URL。

正斜杠应为负前瞻的一部分，因为这是您不想直接位于右侧的字符串。

您的模式可能如下所示：

\b(?:https?:\/\/)?(?:\w+\.)*website\.com(?!\/team|\/forum)\S*

那会匹配

• \\b(?:https?:\\/\\/)? 单词边界，后跟可选的http（s）：//
• (?:\\w+\\.)*匹配0+次1+个单词字符，后跟一个点
• website\\.com匹配website.com
• (?!\\/team|\\/forum)负向断言来断言直接在右边的不是/ team或/ forum
• \\S*匹配0+次非空格字符

检查以下正则表达式，

(https?:\/\/)?(www.website.com)(\/)?(?!team|forum)(\w)*

单击此处进行演示。 在这里您可以找到正则表达式的每个部分，以供您理解

此正则表达式在以下测试用例上进行了测试

1. www.website.com =允许
2. https://www.website.com =允许
3. http://www.website.com =允许https://www.website.com/team =不允许
4. https://www.website.com/forum =不允许
5. https://www.website.com/samplepage =允许
