尝试添加强制 HTTPS 规则时的 .htaccess 重定向循环（Amazon Elastic Beanstalk）

Question

我在尝试在生产环境中加入强制 HTTPS 的规则后开始收到此错误。 BWC_ENV 环境变量可以有几个不同的值：“prod”、“stage”、“ben_local”、“nam_local”等。

这是我的 .htaccess：

RewriteEngine On

# Force HTTPS
RewriteCond %{HTTPS} !=on
RewriteCond %{ENV:BWC_ENV} ^prod$
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# Parse the subdomain as a variable we can access in our scripts
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{HTTP_HOST}        !^www
RewriteCond %{HTTP_HOST}         ^([^\.]+)\.([^\.]+)\.([^\.]+)$
RewriteRule ^(.*)$ /$1?subdomain=%1

# Ditto for the path; map all requests to /index.php
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !robots.txt
RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] 

# robots.txt - supply the correct one for each environment
RewriteRule ^robots.txt$ /robots.prod.txt [NC] 
RewriteCond %{ENV:BWC_ENV} !prod
RewriteRule ^robots.prod.txt$ /robots.stage.txt [NC]

更重要的是，如果我的 .htaccess 只包含以下内容，这也会导致重定向循环。为什么会这样？

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Answer 1

事实证明这是 Amazon Elastic Load Balancer 的事情。您必须使用 Amazon 的 X-Forwarded-Proto 标头来完成此操作：

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule !/status https://%{SERVER_NAME}%{REQUEST_URI} [L,R]

Answer 2

您在几条规则中缺少L 标志。键入将您的代码更改为：

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

# Force HTTPS
RewriteCond %{HTTPS} !=on
RewriteCond %{ENV:BWC_ENV} ^prod$
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# Parse the subdomain as a variable we can access in our scripts
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{QUERY_STRING} !^$
RewriteCond %{HTTP_HOST}        !^www
RewriteCond %{HTTP_HOST}        ^([^.]+)\.[^.]+\.[^.]+$
RewriteRule ^(.*)$ /$1?subdomain=%1 [L,QSA]

# Ditto for the path; map all requests to /index.php
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !robots.txt
RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] 

# robots.txt - supply the correct one for each environment
RewriteRule ^robots.txt$ /robots.prod.txt [L,NC] 
RewriteCond %{ENV:BWC_ENV} !prod
RewriteRule ^robots.prod.txt$ /robots.stage.txt [NC,L]
