htaccess移除WWW或HTTPS时跳转异常显示index.php路径问题

问题原因 #

你的问题完全是规则顺序错误导致的：

• 你把强制HTTPS、WWW、末尾斜杠这类外部跳转规则放在了所有内部重写规则的后面。用户的访问请求会先被前面的重写规则把路径重写成/index.php?module=xxx的格式，等到触发跳转时，拿到的已经是重写后的路径，自然不会保留原本的/home/后缀。
• 大量使用[N]标志会让重写流程反复从头执行，进一步放大了路径被篡改的问题。

修复方案 #

直接调整规则顺序，把所有外部跳转逻辑移到所有内部重写规则的最前面，跳转执行完成之后再跑内部重写的逻辑即可。调整后的完整规则如下：

# 所有外部跳转规则放在最前面
Redirect 301 /podcast_rss_ogg.php /podcast_rss.php?format=ogg

# 强制WWW前缀
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L]

# 强制HTTPS
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

# 强制末尾斜杠
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)([^/])$ /$1$2/ [L,R=301]

# 以下为内部重写规则
RewriteRule ^image_prox/([%\w\.-_]*)$ /includes/image_proxy.php?url=$1 [N,NC]

修改后记得清空浏览器缓存再测试，301跳转是永久缓存，旧的错误跳转结果会存在本地导致测试不准。
