nginx在javascript文件上过期（由PHP动态生成）

Question

我在PHP生成的javascript文件上遇到了expires标题的问题。

该网站有两种类型的javascript文件。一部分是静态javascript文件，一部分是由PHP动态生成的。

conf没有过期标题

此处expires文件中没有添加.js标题（所有文件都返回HTTP 200）

location / {
    try_files  $uri $uri/ /index.php;
}

location ~ \.php$ {
    include  /var/ini/nginx/fastcgi.conf;
    fastcgi_pass  php;
    fastcgi_param  SCRIPT_FILENAME /var/www/index.php;
}

conf with expires headers

为.js文件添加位置时，所有动态生成的文件都会返回HTTP 404

location / {
    try_files  $uri $uri/ /index.php;
}

location ~ \.php$ {
    include  /var/ini/nginx/fastcgi.conf;
    fastcgi_pass  php;
    fastcgi_param  SCRIPT_FILENAME /var/www/dyndev.dk/public/secure/index.php;
}

location ~ \.(js|css)$ {
    expires 1y;
    add_header Cache-Control "public";
}

如何使用.js标题处理静态和动态生成的expires文件？

所有动态生成的javascript文件都命名为*-php.js

文件结构

/var/www/public/index.php # All none-static file requests are pointed to index.php
/var/www/public/js/main.js # Static files
/var/www/js-dynamically_generated.php # This file is outside the public www, but is routed by PHP since the file doesn't exists inside the public /js

PHP路由

www.example.com/ -> index.php
www.example.com/js -> static content
www.example.com/js/dynamically_generated-php.js -> js-dynamically_generated.php

对于nginx，PHP绝不是Javascript。 Nginx无法区分呈现html的PHP和呈现javascript的PHP（如果我错了请纠正我）。

所以要做的就是设置一个单独的文件夹，其中包含生成所有JS的PHP文件（代码未经过测试！）：

location ~ \normal_php/.php$ {
    include  /var/ini/nginx/fastcgi.conf;
    fastcgi_pass  php;
    fastcgi_param  SCRIPT_FILENAME /var/www/dyndev.dk/public/secure/index.php;
}

location ~ \js_php/.php$ {
    expires 1y;
    add_header Cache-Control "public";

    include  /var/ini/nginx/fastcgi.conf;
    fastcgi_pass  php;
    fastcgi_param  SCRIPT_FILENAME /var/www/dyndev.dk/public/secure/index.php;
}

...或者用PHP本身发送标题：

<?php
header('Expires: '. gmdate('D, d M Y H:i:s \G\M\T', time() + (60 * 60))); // 1 hour
