mod_rewrite 与组合 2 个条件/规则发生冲突

【问题标题】：mod_rewrite conflict with combining 2 conditions/rulesmod_rewrite 与组合 2 个条件/规则发生冲突
【发布时间】：2022-01-16 06:20:48
【问题描述】：

我正在使用这个 mod_rewrite 规则来在我们的网站上避免 .php 结尾：

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} -f
RewriteRule ^([^\.]+)$ $1.php [NC,L,QSA]

效果很好，website.com/login.php 变成 website.com/login

现在我想介绍一个使用 website.com/username

的用户名系统 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ /profile.php?user=$1 [L,QSA]

两个规则/条件都按预期工作，但同时使用它们会导致冲突，例如自定义“未找到配置文件”消息，即使在 条款之类的页面上也是如此。 php

有没有机会结合这些规则/条件首先检查是否存在现有的 .php 文件，如果没有，请尝试配置文件用户名？或者甚至提示如何更好地解决这个问题？

示例： website.com/netsetter

  1. 如果 netsetter.php 存在，使用 netsetter.php
  2. 如果 netsetter.php 不存在，使用 profile.php?user=netsetter

【问题讨论】：

  • 用户名可以包含点吗？
  • 用户名中实际上没有点，甚至没有数字，但将来可能会。

标签： apache mod-rewrite


【解决方案1】：

假设这些指令直接在服务器配置（或虚拟主机）中，而不是 &lt;Directory&gt; 容器或 .htaccess 文件中。

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} -f
RewriteRule ^([^\.]+)$ $1.php [NC,L,QSA]

旁白：这里的第二个条件没有意义。它在附加.php 之前检查初始请求是否映射到文件。如果初始请求确实映射到文件，您当然不想附加.php。幸运的是，它完全是多余的，因为 RewriteRule pattern ^([^\.]+)$ 不包括点，因此该规则自然会排除无论如何都会映射到实际文件的请求（除非您有没有文件扩展名的文件- 不太可能）。

这里只有第一个检查请求未映射到目录的条件实际被使用。

这实际上是无条件地重写请求，而不管目标.php 文件是否存在。最好先检查一下，这将有助于解决您与用户名的冲突（如您所建议的那样）。

注意：您确实应该在此处使用REQUEST_URI 变量（或$1 反向引用）而不是REQUEST_FILENAME。 REQUEST_FILENAME 旨在包含绝对文件系统路径，因此将其附加到 DOCUMENT_ROOT 通常没有意义。只是在 server（或 virtualhost）上下文中使用时，REQUEST_FILENAME 包含与 REQUEST_URI 相同的内容（即相对于根的 URL 路径）。

效果很好，website.com/login.php 变成 website.com/login

旁白：这条规则实际上正好相反。 /login 变为 /login.php。另一种方式是外部重定向和不同的指令。

所以，将上面的内容改为：

RewriteCond %{DOCUMENT_ROOT}$1.php -f
RewriteRule ^([^.]+)$ $1.php [L]

这会在重写请求之前检查请求 + .php 是否存在。在检查请求 + .php 是否映射到文件之前，无需检查请求是否直接映射到 a。

无需对正则表达式字符类中的文字点进行反斜杠转义。

不需要NC 或QSA 标志。正则表达式已经不区分大小写，因为它同时匹配 a-z 和 A-Z。并且请求中的任何查询字符串都会自动附加，除非您在 substitution 中明确包含查询字符串。

那么，如果用户名不能包含点，您可以使用以下规则来管理/username。例如：

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/.]+)/?$ /profile.php?user=$1 [L,QSA]

您可能需要首先检查请求未映射到目录的条件。

但是，如果 usernames 可以包含确实，则从正则表达式中删除点并包含一个附加条件以排除已经映射到文件的请求（在文档根目录中）：

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ /profile.php?user=$1 [L,QSA]

总结

# Extensionless URLs
RewriteCond %{DOCUMENT_ROOT}$1.php -f
RewriteRule ^([^.]+)$ $1.php [L]

# Rewrite "/Usernames"
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ /profile.php?user=$1 [L,QSA]

  • 感谢@MrWhite 的精彩回答。但是，通过使用您的“摘要”，我在每个页面请求上都收到“未找到配置文件”自定义错误消息，因此我更新了包含完整配置的原始问题，以便快速查看是否有其他规则覆盖您的摘要?
