htaccess语法RewriteRule [英] Htaccess syntax RewriteRule

问题描述

我想尝试了解我的一些htaccess规则，但无法成功找到合适的文档。

I would like to try to understand some of my htaccess rules but I can't succeed to find the proper documentation.

RewriteRule ^([a-z]{1,2})?\/?style\/(.*).css$ site/scripts/concat-files.php?type=css&page=$2&lang=$1 [L,QSA]

问题1：
我猜这条规则是由这样的事情触发的。 < link rel = stylesheet src =<？php echo URL？> / en / style / accueil.css>
我对 ？

Question 1: I guess this rule is triggered by something like this. <link rel="stylesheet" src =<?php echo URL ?>"/en/style/accueil.css"> Am I right ?

问题2：我知道QSA允许将请求参数从第一个URL保留到重写URL。但是L在做什么？

Question 2: I know QSA allow to keep the request parameter from the first url to the rewrite URL. But what L is doing ?

问题3：规则是由这种事情触发的吗？

Question 3 : Is the rule triggered by this kind of things ?

$urlstyle = URL."en/style/accueil.css";
$style = file_get_contents($urlstyle);

谢谢。

编辑：然后考虑此

$urlstyle = URL_SITE.'en/style/accueil.css';
$style = file_get_contents($urlstyle);
echo $style;

样式已编写。

但是在我的concat-files.php中

But in my concat-files.php

我有这个

$pathfile= PATH . $file;
$sContenu = @file_get_contents( $pathfile);
if( $sContenu !== false) {
    echo $sContenu;
}

这意味着Accueil CSS将被写入2次，否？

It means that accueil css will be written 2 times no ?

但是在我的代码中，我只有一次。

But in my code I have it only once.

推荐答案

如@nick在评论中所述

1-该规则由任何满足规则本身的http请求触发。或者更确切地说：

Edit
As @nick said in the comments
1 - The rule is triggered by any http request that satisfy the rule itself. or rather :

`1 or 2 alphabetic characters` / style / `any string`.css

2- [L] 表示仅第一条规则适用，其他规则匹配将被忽略。

2 - [L] means thats only first rule will apply, other rules match will be ignored.

3-是的，正如我所说，该规则由满足规则本身的所有http请求触发

3 - Yes, as i said The rule is triggered by any http request that satisfy the rule itself

Edit2

不，看来您没有两次输出相同的内容。

No, it seems that you are not outputting same content two times.

$style = file_get_contents($urlstyle);

您正在将内容分配给 $ style 网址（由一些php代码生成）。
与 include 函数的行为不同，在这种情况下，这两段代码都将被执行和写入两次。

因此，您只需一次就可以了。

You are assigning to $style the content of an url (generated by some php code). Is a different behaviour from, for example, include function, in that case both pieces of code would be executed and written two times.
So its ok that you have it only once.
