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 规则
Rewrite 规则是指 Nginx 服务器在处理请求时，根据一定的规则对请求的 URL 进行修改，从而实现 URL 重写或重定向。
Rewrite 模块
Nginx 的 Rewrite 模块是处理 Rewrite 规则的核心模块，它负责解析和执行 Rewrite 规则。

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 /old/ 开头的 URL 重定向到 /new/ 目录下，保持 URL 后缀不变。

使用 RewriteCond 和 RewriteRule

RewriteCond 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
