Apache 编码 URI 导致 404

Apache 编码 URI 导致 404

我遇到了一个奇怪的问题。我使用的框架在 mod_rewrite 重写 URL 后被调用。如果 URI 中的字符带有重音符号（如拉丁字母），则请求永远不会发送到我的框架，而服务器会出错并显示 404。我使用的是 Windows 计算机，因此不确定这是否与此有关。只要 URI 中没有重音符号，请求就会毫无问题地发送到框架。有人能告诉我这是怎么回事以及如何解决这个问题吗？

编辑：以下是我的 access.log 中的两行。第一行显示 404，其中重音符号Å由 Apache 编码，但未传递。当我将ÅURI 中的 更改为英文“A”时，一切都按预期运行。

127.0.0.1 - - [20/Oct/2017:13:50:50 -0400] "GET /actor/%C3%85ker HTTP/1.1" 404 222
127.0.0.1 - - [20/Oct/2017:13:54:48 -0400] "GET /actor/Aker HTTP/1.1" 200 5701

编辑：.htaccess这些是文件 中的行

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php?request=$1 [L,QSA]

这是由两个人组成的调试日志的一部分，其中显示对于其中一个人，mod_rewrite 没有将请求转发到我的框架，而另一个人却转发了。

这是失败的：

为什么其中一个有效而另一个无效？两个名字中都有重音符号，但其中一个失败了。

答案1

一个假设……

RewriteRule .* index.php?request=$1 [L,QSA]

这行看起来就像一个错误，因为$1反向引用将总是为空，因为没有捕获组RewriteRule 图案。

“框架”可能仍然有效（对于拉丁字母），因为它可能正在解析$_SERVER['REQUEST_URI']PHP 超全局变量（可能作为后备）——许多框架都是这样做的。但是，$_SERVER['REQUEST_URI']将保持 URL 编码（例如/actor/%C3%85ker）——因此，在通过框架路由之前，可能需要对其进行 URL 解码（例如/actor/Åker）。这可能是问题所在。另一方面，像这样的请求/actor/Aker无论是否经过 URL 编码都是相同的，因此这不会影响这样的 URL。

但是，如果您的框架允许使用 URL 参数覆盖请求的 URL，request那么请考虑将上述指令更改为：

 RewriteRule (.*) index.php?request=$1 [L,QSA]

即附上RewriteRule 图案在括号内。

这将导致捕获的 URL 路径在requestURL 参数中传递。现在，与此的重要区别在于，指令RewriteRule匹配的 URL 路径已经经过 URL 解码。因此，requestURL 参数已经包含 URL 解码的请求（尽管少了斜杠前缀），例如actor/Åker。。

更新：尝试改变RewriteRule 图案改为从.*到[\s\S]*。例如：

 RewriteRule ([\s\S]*) index.php?request=$1 [QSA,L]

这只是一个稍微更全面的模式。虽然.（点）匹配任何字符（不包括换行符），但[\s\S]匹配任何空格和非空格字符（即。一切）。

  1. 查看日志。Apache 错误日志中显示其正在查找的文件的路径是什么？该文件的路径是否存在？

  2. 这听起来像是字符编码问题。确保在 Apache 中正确配置了字符编码。不幸的是，我对此没有具体的建议。
