Nginx缓存密钥$uri可以'；t区分URL'；s

我正在使用nginx缓存我的站点。然而，默认的fastcgi_缓存_密钥选项“$scheme$request\u method$host$request\u uri”对我来说并不好，因为我使用我的站点进行付费流量，并且它发送了许多类似UTM的参数

我想忽略参数，所以我将$request_uri更改为$uri

但现在，当我重新加载nginx时，我尝试访问一个随机页面，它将显示标题：“x-cache:MISS”，并正确显示此页面。但现在每次我尝试访问任何页面时，它都会显示我访问的第一个页面和“x-cache:HIT”，即使是不存在的页面，它也会显示第一个页面

我的确认：
