正则表达式（连字符，下划线和句点）

Question

I need a regular expression that will be able to detect:

https://s-dPICS-sac323.domain.com/a12_hyJ_k87ds_x.jpg

Will this code do it:

var x = /(https:\/\/[A-Za-z0-9.-]*PICS[A-Za-z0-9._\/]*\.jpg)/g;

Will this be able to detect something along the lines of:

Note: everything except https:// , PICS , domain.com , and .jpg are random alpha-numeric characters for this example. I'm trying to detect all of the rest of the characters.

Thanks for your help!

Answer 1

Try this instead:

/https:\/\/[a-z0-9.-]*photos[\w.\/-]*\.jpg/i

Answer 2

不要逃避正常斜线，它们不是魔法角色。

    /https:\/\/[\w.-]+PICS[\w.\/-]+\.domain\.com/[\w.\/-]+\.jpg/

Answer 3

/(https:\\/\\/[A-z0-9.-]*PICS[A-z0-9.-]*domain\\.com[A-z0-9.-/_]*\\.jpg)/ will match "https://s-dPICS-sac323.domain.com/a12_hyJ_k87ds_x.jpg".

And /(https:\\/\\/[A-z0-9.-]*photos[A-z0-9/.-]*\\.jpg)/ will match "https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-snc3/12868_695309462154_5301742_40115272_5760577_n.jpg" with https:// , photos , and .jpg being constant.
