Nginx 缓存密钥 $uri 无法区分 URL 的

如何解决Nginx 缓存密钥 $uri 无法区分 URL 的

我正在使用 nginx 来缓存我的网站。但是，默认的 fastcgi_cache_key 选项“$scheme$request_method$host$request_uri”对我不利，因为我将我的网站用于付费流量，并且它会发送很多像 UTM 一样的参数。

我想忽略参数，所以我将 $request_uri 更改为 $uri。

但是现在，当我重新加载 nginx 时，我尝试访问一个随机页面，它会显示标题：“x-cache: MISS”并正确显示此页面。但是现在每次我尝试访问任何页面时，它总是会显示我访问的第一页和“x-cache：HIT”，即使页面不存在，它也会显示第一页。

我的配置：

fastcgi_cache_path /etc/nginx/cache levels=1:2 keys_zone=WP:100m inactive=60m;
fastcgi_cache_key "$scheme$request_method$host$request_uri";

server {
  listen 80;
  listen [::]:80;

  server_name example.com;

  return 301 https://example.com$request_uri;
}

server {
  listen 443 ssl http2;
  listen [::]:443 ssl http2;

  root /var/www/html/example.com;
  index  index.php;
  server_name example.com;

  ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

  error_log /var/log/nginx/example.com_error.log;
  access_log /var/log/nginx/example.com_access.log;

  client_max_body_size 1024M;

  add_header X-Cache $upstream_cache_status;
  fastcgi_cache_use_stale error timeout invalid_header http_500;
  fastcgi_ignore_headers Cache-Control Expires Set-Cookie;

  set $skip_cache 0;

  # POST requests and urls with a query string should always go to PHP
  if ($request_method = POST) {
    set $skip_cache 1;
  }
  if ($query_string != "") {
    #set $skip_cache 1;
  }

  # Don't cache uris containing the following segments
  if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") {
    set $skip_cache 1;
  }

  # Don't use the cache for logged in users or recent commenters
  if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") {
    set $skip_cache 1;
  }

  location = /favicon.ico {
    log_not_found off;
    access_log off;
  }

  location = /robots.txt {
    allow all;
    log_not_found off;
    access_log off;
  }

# Media: images,icons,video,audio,HTC
location ~* \.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|mp3|ogg|ogv|webm|htc|woff2|woff)$ {
    expires 1M;
    access_log off;
    # max-age must be in seconds
    add_header Cache-Control "max-age=2629746,public";
}

# CSS and Javascript
location ~* \.(?:css|js)$ {
    expires 1y;
    access_log off;
    add_header Cache-Control "max-age=31556952,public";
}

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

  location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_intercept_errors on;
    fastcgi_pass             unix:/var/run/php/php-fpm.sock;
    fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;

    fastcgi_cache WP;
    fastcgi_cache_valid 200 60m;

    fastcgi_cache_methods GET HEAD;
    fastcgi_cache_bypass $skip_cache;
    fastcgi_no_cache $skip_cache;
  }
}

非常感谢，对不起我的英语
