光油不與WooCommerce合作

Question

我們正在嘗試將Varnish添加到我們的Woocommerce設置中，並且遇到了一些麻煩。

在產品頁面（可以說/產品/電視）上，如果按下「添加到購物車」按鈕，您現在已按預期重定向到購物車頁面，但該商品尚未添加到購物車。
但是，如果您在登錄帳戶時執行同樣的操作，它將正常工作。我已經發布了我的varnish.vcl文件，如果有人有任何問題，請告訴我。

我找到了解決這個問題就在這裏： https://guides.wp-bullet.com/fix-empty-cart-with-woocommerce-redirect-to-checkout-varnish-4/

基本上當你添加項目到購物車，Woocommerce發出302重定向，併發送你的車（你可以禁止這種行爲設置）。在Varnish中，當發生此事件時，您必須確保不會從後端響應中刪除任何Cookie。

sub vcl_backend_response { 
    if (!(bereq.url ~ "wp-(login|admin)|cart|my-account|wc-api|resetpass") && 
    !bereq.http.cookie ~ "wordpress_logged_in|woocommerce_items_in_cart|resetpass" && 
    !beresp.status == 302) { 
     unset beresp.http.set-cookie; 
     set beresp.ttl = 1w; 
     set beresp.grace = 1d; 
    } 
}
