Question

我在serverfault上问了这个问题，但没有人回答。希望，stackoverflow人更了解Nginx：）

我想处理从缓存到/ api的所有[GET]请求，并处理所有其他请求，就像在最后一个位置块（没有缓存）一样。使用PUT，POST，DELETE方法对/ api的所有请求也都不能使用缓存。

我看到了类似的问题here，但在我的案例中仍然无法理解如何使用它。

提前致谢。

我的配置：

location / {
    root /var/www/project/web;
    # try to serve file directly, fallback to app.php
    try_files $uri /app.php$is_args$args;
}


location ~ ^/api {
    root /var/www/project/web/app.php;
    fastcgi_send_timeout 600s;
    fastcgi_read_timeout 600s;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_split_path_info ^(.+\.php)(/?.*)$;
    include fastcgi_params;
    fastcgi_cache fcgi;
    fastcgi_cache_valid 200 5m;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param HTTPS off;

}

location ~ ^/(app|app_dev|config)\.php(/|$) {
    root /var/www/project/web;
    fastcgi_send_timeout 600s;
    fastcgi_read_timeout 600s;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_split_path_info ^(.+\.php)(/?.*)$;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param HTTPS off;
}

谢天谢地，这很简单。 Nginx的模块（proxy，fastcgi，uwsgi等）都能够通知请求不使用缓存。

location ~ ^/api {
    root /var/www/project/web/app.php;
    fastcgi_send_timeout 600s;
    fastcgi_read_timeout 600s;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_split_path_info ^(.+\.php)(/?.*)$;
    include fastcgi_params;

    # Don't cache anything by default
    set $no_cache 1;

    # Cache GET requests
    if ($request_method = GET)
    {
        set $no_cache 0;
    }

    fastcgi_cache_bypass $no_cache;
    fastcgi_no_cache $no_cache;

    fastcgi_cache fcgi;
    fastcgi_cache_valid 200 5m;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param HTTPS off;
}

根据Richard Smith的建议，使用maps指令的更优雅的解决方案如下：

map $request_method $api_cache_bypass {
    default       1;
    GET           0;
}

location ~ ^/api {
    root /var/www/project/web/app.php;
    fastcgi_send_timeout 600s;
    fastcgi_read_timeout 600s;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_split_path_info ^(.+\.php)(/?.*)$;
    include fastcgi_params;

    fastcgi_cache_bypass $api_cache_bypass;
    fastcgi_no_cache $api_cache_bypass;

    fastcgi_cache fcgi;
    fastcgi_cache_valid 200 5m;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param HTTPS off;
}

该位置的添加实质上是告诉Nginx使用或忽略缓存，具体取决于动词。它将$ no_cache设置为1，它将绕过所有请求的缓存，除非该方法是GET，当它设置为0时指示它使用缓存（如果可用）。
