nginx [emerg] 未知的“0”变量

Question

我已经尝试了两天将 .htaccess 转换为 nginx 重写原始文件如下所示：

# Turn on URL rewriting
RewriteEngine On

RewriteBase //

# Protect hidden files from being viewed
<Files .*>
Order Deny,Allow
Deny From All
</Files>

# Protect application and system files from being viewed
RewriteRule ^(?:application|modules|system)\b.* index.php/$0 [L]

# List of files in subdirectories will not be displayed in the browser
Options -Indexes

# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

AddDefaultCharset utf-8
AddCharset UTF-8 .htm .html .txt
AddType "text/html; charset=UTF-8" .htm .html .txt
AddType "text/css; charset=UTF-8" .css
AddType "text/javascript; charset=UTF-8" .js

# Rewrite all other URLs to index.php/URL
RewriteRule .* index.php/$0 [PT]

我想出了这个：

# nginx configuration 
charset utf-8; 
autoindex off; 

location /application {
rewrite ^/(?:application|modules|system)\b.* /index.php/$0 break;
} 
location /modules {
rewrite ^/(?:application|modules|system)\b.* /index.php/$0 break;
}
location /system { 
rewrite ^/(?:application|modules|system)\b.* /index.php/$0 break; 
} 
location / { 
if (!-e $request_filename){ 
rewrite ^(.*)$ /index.php/$0; 
} 
} 
location ~ \.* { 
deny all; 
}

但是当我重新启动 nginx 时，我得到：

[emerg] unknown "0" variable
nginx: configuration file /etc/nginx/nginx.conf test failed

我不明白这是为什么。有人可以帮我解决这个问题吗？

Answer 1

nginx 没有该$0变量，该变量在 Apache 中用于 Apache 中的整个正则表达式模式匹配。

在 nginx 中，您可以使用 获得等效的字符串$request_uri。

因此，您应该使用如下配置：

charset utf-8;
autoindex off;

location ~ /\.* {
    deny all;
}

location ~ /(?:application|modules|system) {
    return 301 /index.php$request_uri;
}

# Try first the actual files, if they do not exist, then try $request_uri via `index.php`.
try_files $uri $uri/ /index.php/$request_uri;

我还在这里修复了隐藏文件正则表达式。
