如果存在文件，则重定向到某个文件，否则从 htaccess 重定向到 404

Question

我有这棵树：

libs/
html/
app/
uploads/
    files/
    images/
        male.png
        female.png
    .htaccess
    download.php
.htaccess
index.php

/.htaccess 有这个内容：

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -Indexes
    </IfModule>

    RewriteEngine On

    RewriteRule ^ index.php [END,L]
</IfModule>

我想要 /uploads/.htaccess 到：

• 重定向到download.php

  • 如果文件存在，但不存在这个 .htaccess 或 download.php

• 重定向 404

  • 如果不匹配现有文件
  • 或匹配 .htaccess 或 download.php
  • 或匹配现有文件夹

示例：

www.example.com/uploads - redirect 404
www.example.com/uploads/files - redirect 404
www.example.com/uploads/images- redirect 404
www.example.com/uploads/.htaccess - redirect 404
www.example.com/uploads/download.php - redirect 404
www.example.com/uploads/nonexistentfile - redirect 404

www.example.com/uploads/images/male.php - redirect download.php
www.example.com/uploads/images/female.php - redirect download.php

下面的讨论应该对您有所帮助： Redirect requests only if the file is not found?

# If requested resource exists as a file or directory go to it
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule (.*) - [L]
#Alternatively the code above redirects where you want

# Else rewrite requests for non-existent resources to /404.php
RewriteRule (.*) /404.php?q= [L]

我也在 serverfault.com 上问过这个问题，我得到了预期的答案： https://serverfault.com/questions/975415/if-file-exists-redirect-to-a-certain-file-else-redirect-to-404-from-htaccess/975451?noredirect=1#comment1269343_975451
