存在RewriteCond文件 [英] RewriteCond file exists

问题描述

这是一个简单的问题，但是htaccess和我从来没有相处过。

Such a simple problem but htaccess and I have never got along.

1. 提供文件（如果存在）。


2. 如果URI只是/并且存在index.html，则提供index.html


3. 否则，提供app.php

这里是.htaccess：

Here is .htaccess:

# Disable the directory processing, Apache 2.4
DirectoryIndex disabled xxx

RewriteEngine On

# Serve existing files
RewriteCond %{REQUEST_FILENAME} -f

RewriteRule .? - [L]

# For / serve index.html if it exists
RewriteCond %{REQUEST_URI} ^/$

RewriteCond    index.html -f

RewriteRule .? index.html [L]

# Otherwise use front controller
RewriteRule .? app.php [L]

如果我将RewriteCond index.html -f行注释为只要index.html确实存在。但是我也想检查index.php，所以我需要检查文件是否存在。而且如果没有别的我想了解为什么张贴的行不起作用。

It works if I comment out the RewriteCond index.html -f line as long as index.html does in fact exists. But I also want to check for index.php so I need the file exists check. And if nothing else I'd like to understand why the posted lines do not work.

推荐答案

这应该起作用：

# Disable the directory processing, Apache 2.4
DirectoryIndex disabled xxx

RewriteEngine On

# Serve existing files
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]

# For / serve index.html if it exists
RewriteCond %{DOCUMENT_ROOT}/index.html -f [NC]
RewriteRule ^/?$ index.html [L]

# Otherwise use front controller
RewriteRule ^ app.php [L]

请记住 RewriteCond -f 或 -d 的文件或目录需要完整路径，这就是为什么需要在文件名前加上％{DOCUMENT_ROOT} / 。无需在这里转义。

Remember that RewriteCond with -f or -d needs full path to the file or directory that's why you need to prefix the filename with %{DOCUMENT_ROOT}/. No need to escape dots here.
