Php PrestaShop webService返回意外的HTTP状态503

我正在将基于PHP的仓库管理系统与PrestaShop1.6集成，并使用PrestashopWeb服务进行集成

我必须使在仓库管理系统中创建的新产品出现在PrestaShop 1.6在线商店中。仓库管理系统要求PrestaShop WebService在PrestaShop在线商店上创建新产品

我已经编写了如下所示的函数。它在本地主机上运行良好，但在测试服务器上，它在尝试更新库存可用性后收到HTTP状态503。所有WebService实体上都启用了所有WebService方法GET、PUT、DELETE等。我不知道如何调试这个问题，你能帮我吗

顺便说一下，我使用了以下代码作为示例：

---

在大多数主机中，PUT请求默认关闭。你有没有和你的托管经理核实过？？ 无论如何，你必须在解决这个问题后，才能知道错误的确切原因

---

祝你好运。

几周后，我被要求回来解决PrestaShop网站服务问题。亲爱的PrestaAlba，非常感谢，你的建议非常有用。我需要取消阻止PUT和DELETE HTTP方法。当然，现在我知道这些PUT和DELETE方法被阻止是因为安全原因，这些方法很容易被利用，所以我只为我们的仓库管理系统所在服务器的一个IP地址解除了这些方法的阻止。
