Php 如何从Wordpress自定义端点内部初始化POST和PUT方法

我正在wordpress中创建一个自定义端点，该端点应执行以下操作： 1.创建路径（完成） 2.调用函数，该函数： 2.1. 从WooCommerce获取所有产品并将其存储在数组中（完成） 2.2. 将WooCommerce上的产品与外部数据库中的产品进行比较，如果数据存在任何差异，则通过外部数据库中的数据进行更新（PUT） 2.3. 如果某些产品存在于外部数据库中，但不存在于WooCommerce中，请在WooCommerce上创建它们（POST）

我已经设法通过wc_get_products（$args）从WooCommerce获取所有数据，但我找不到如何编写PUT和POST方法来更新或创建产品。 如果我使用Automatic/WooCommerce从独立文件（不是从自定义端点）推送或放置产品，但如果我将Automatic/WooCommerce保留在自定义端点上，它会告诉我以下信息：

Failed to connect to localhost port 8000: Connection refused in /var/www/html/wp-content/plugins/wl-api/vendor/automattic/woocommerce/src/WooCommerce/HttpClient/HttpClient.php on line 417 

这是完全有意义的，因为从自定义端点我已经连接到WooCommerce，并且自动/WooCommerce将尝试再次连接。除了PUT和PUSH之外，还有像wc_get_产品这样的方法吗

我将非常感谢与我的问题有关的任何意见。谢谢大家!

要获得POST和PUT，您需要实现这些方法（动词）

您可以使用：

$verb = $_SERVER['REQUEST_METHOD'];
echo $verb;

。。。测试您正在使用的HTTP请求方法（PUT vs GET）
