Nginx 配置 ReWrite：高效处理 URL 重写与重定向
Nginx 是一款高性能的 HTTP 和反向代理服务器，它以其轻量级、稳定性高、配置灵活等特点被广泛应用于各种场景，在 Nginx 的配置中，Rewrite 功能是实现 URL 重写和重定向的重要手段，可以帮助我们优化网站结构、提高用户体验，本文将详细介绍 Nginx 配置 Rewrite 的方法和技巧。
Rewrite 基础概念
Rewrite 配置步骤
开启 Rewrite 模块在 Nginx 的配置文件中，首先需要开启 Rewrite 模块,具体操作如下：
http {...server {...location / {...if (!-e $request_fileName) {rewrite ^/(.*)$ /index.php?$query_string last;}}}}
编写 Rewrite 规则在 location 块中，我们可以编写 Rewrite 规则，以下是一个简单的 Rewrite 规则示例：
location /old/ {rewrite ^/old/(.*)$ /new/$1 permanent;}
这个规则将所有以开头的 URL 重定向到目录下，保持 URL 后缀不变。
使用 RewriteCond 和 RewriteRuleRewriteCond 用于判断是否执行 RewriteRule，RewriteRule 用于定义具体的重写规则，以下是一个结合 RewriteCond 和 RewriteRule 的示例：
location /old/ {rewritecond $request_URI ~ /old/rewritecond $request_uri !~ /old/(index|login)/rewritecond $request_uri !~ /old/rewritecond $request_uri !~ ^/old$rewritecond $request_uri !~ ^/old$rewritecond $request_uri !~ ^/old$rewritecond $request_uri !~ ^/old$rewritecond $request_uri !~ ^/old$rewritecond $request_uri !~ ^/old$rewritecond $request_uri !~ ^/old$rewritecond $request_uri
