具有多個目錄的URL的正則表達式

Question

我想匹配與數字和文本混合的特定格式。數字是不同的日期。

這些應該符合：

/shop/2017/12/04/string-of-text/another-string-of-text

/shop/2017/12/04/string-of-text/another-string-of-text/

但這些不應該：

/shop/2017/12/04/string-of-text/another-string-of-text/more-text

/shop/2017/12/04/string-of-text/

/shop/2017/12/04/string-of-text

---

這甚至可能嗎？

到目前爲止，我已經得到了這一步，但它似乎在某些情況下，以匹配它不應該：

^/shop/(.*?)/(.*)/(.*)/(.*)/(.*)$

Answer 1

你需要躲避/和非常肯定你不」 t最後要放.*，因爲這將在最後的/之後匹配任何東西，這不會是你所需要的;試試這個/^\/shop\/\d{4}\/\d{2}\/\d{2}(?:\/[^/]+){2}\/?$/;

• ^\/shop匹配/shop開頭;
• \/\d{4}\/\d{2}\/\d{2}匹配/year/month/day;
• (?:\/[^/]+){2}\/?$匹配另外兩個文本塊，最後是可選的/;

var samples = ["/shop/2017/12/04/string-of-text/another-string-of-text", 
 
       "/shop/2017/12/04/string-of-text/another-string-of-text/", 
 
       "/shop/2017/12/04/string-of-text/another-string-of-text/more-text", 
 
       "/shop/2017/12/04/string-of-text/", 
 
       "/shop/2017/12/04/string-of-text"] 
 

 
console.log(
 
    samples.map(s => /^\/shop\/\d{4}\/\d{2}\/\d{2}(?:\/[^/]+){2}\/?$/.test(s)) 
 
);
