NGINX+Wordpress 缓存悖论

Jas*_*enX 2 wordpress caching nginx

我正在运行 Wordpress + NGINX + PHM-FPM。我对 NGINX 配置进行了这些更改,这些更改取自我遇到的最佳实践文章:

#Don't cache if there is a cookie called PHPSESSID
if ($http_cookie ~* "PHPSESSID"){
    set $no_cache 1;
}

#Don't cache if there is a cookie called wordpress_logged_in_[hash]
if ($http_cookie ~* "wordpress_logged_in_"){
    set $no_cache 1;
}

然而,这意味着在使用 PHPSESSID cookie 时,帖子页面(我的大部分点击)不会在请求时被缓存。帖子页面不包含每个用户的上下文,并且是通用的。有没有更好的方法只允许缓存帖子页面?也许使用“domain.com/yyyy/mm/dd/post-name”模式?

这是我通常用来专门禁用 Wordpress/Woocommerce 网站的 Fast-CGI 缓存的块,它可能会有所帮助:

#disabler
set $no_cache 0;

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

# Don't cache uris containing the following segments
if ($request_uri ~* "/wp-admin/|/wp-login/|/xmlrpc.php|index.php|phpmyadmin|sitemap(_index)?.xml|sitemap$") {
    set $no_cache 1;
}   
if ($request_uri ~* "(/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {
    set $no_cache 1;
}
if ($request_uri ~* "(/wp-admin/|/cart/|/checkout/|/account/|/mon-compte/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {
    set $no_cache 1;
}

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

# Woocommerce
if ($request_uri ~* "/store.*|/cart.*|/my-account.*|/checkout.*|/addons.*|/panier.*|/paiement.*|/mon-compte.*") {
    set $no_cache 1;
}

if ( $arg_add-to-cart != "" ) { 
   set $no_cache 1;
}

# need more tests
#if ( $cookie_woocommerce_items_in_cart != "0" ) {  
#   set $no_cache 1;
#}

if ( $cookie_woocommerce_items_in_cart ) {
    set $no_cache 1;
}

这是我找到的多篇文章和要点的汇总。请注意,我通常在每个块中添加标头,以查看测试期间禁用缓存的标头。有些规则可能会重复。

注销后,用户仍然拥有一些 cookie,因此有时会绕过缓存。但在大多数情况下它都能正常工作。

当然,全部或部分实施需要测试。

我在Wordpress Nginx Helper插件中使用它,这对于全局和条件清除非常有用。
