图像重写
这可能更像是一个检查而不是一个问题，但以下是正确的：
RewriteRule ^_images/(.*)_(.*)_(.*)$ /_images/$2_$3 [L]
基本上我想自动使网页使用 /_images/picture-name_ABC123_600.jpg （实际上并不存在）但实际上使用确实存在的图像 /_images/ABC123_600.jpg 。
我在 XAMPP 本地对其进行了检查，并且工作正常，但是我认为我最好尝试添加更多下划线，例如。 /_images/picture-name_A_B_C_1_2_3_600.jpg 我期待它能工作，但图像仍然出现 - 那么这是正常行为吗？
我也不太确定是否可以在上面的两个美元符号之间使用下划线...
任何帮助都会很棒！
This is probably more of a check than a question, but is the following correct:
RewriteRule ^_images/(.*)_(.*)_(.*)$ /_images/$2_$3 [L]
Basically I want to automatically make webpages use /_images/picture-name_ABC123_600.jpg (which doesn't really exist) but actually use the image /_images/ABC123_600.jpg that does exist.
I gave it a check locally in XAMPP, and worked, however I though that I'd better try adding more underscores eg. /_images/picture-name_A_B_C_1_2_3_600.jpg which I was expecting to work, yet the image still appeared - so is this normal behavour?
I'm also not too sure if I can use an underscore between the two dollar signs above...
Any help would be great!

这不会起作用，因为
(.*)是贪婪的，会匹配尽可能多的字符，甚至是下划线。像这样（分隔符之间不允许下划线）：或这样（不贪婪的匹配）：
或两者的组合应该可以工作。 （取决于每个块中允许的字符）
This will not work as the
(.*)is greedy and matches as many characters as it can, even underscores. Something like this (not allowing underscore between the separators):or this (ungreedy matching):
or a combination of both should work. (Depending of what chars are allowed within each block)
