.htaccess重写规则未提交发布表单数据？

问：

htacccess 重写 URL 规则没有 .php 扩展名，还有一些带有类别名称作为参数的 URL 我已经成功地完成了这两个工作，但是在此之后，我的帖子表单方法不起作用，我需要帮助，这是我的 .htacess 代码和表单

RewriteEngine On
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+(.+)\.php [NC]
RewriteRule ^ /%1 [R=301,L]

# Rewrite extensionless URLs to .php extension
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^([^\.]+)$ $1.php [NC,L]


RewriteBase /






# Redirect requests for category URLs to category.php with the category parameter
RewriteRule ^collections/([^/]+)/?$ collections/category.php?category=$1 [L]

RewriteRule ^categories/([^/]+)/?$ categories/category_url.php?category=$1 [L]

这是一个 formn 代码

<form action="/update_cart" method="POST"> 
                        
                        <input type="hidden" name="p_sku" value="<?php echo $pro['sku']; ?>"></form>

也带有 ajax 请求

xhr.open('POST', '/update_cart', true);

我尝试以操作形式更新 URL，您可以在表单操作属性中看到
