我已经在ubuntu22.04上配置并安装了ejabberd，我已经成功地配置并创建了一个具有管理员权限的用户，并创建了一些用户。

我正在使用版本
*操作系统- Ubuntu 22.04 LTS
*10月22日

还通过mod_http_api配置了ejabberd API，然后我用POSTMAN测试了API，除了send_message之外，几乎所有（link）“API引用”都能正常工作。
下面是我的ejabberd.yml配置：-

  - B660M-D2H-DDR4

我对消息（send_message）有两点看法：

• 客户端到客户端（PSI）
• Postman 至客户

在第一次观察中，我成功地在psi（PSI）上的用户之间交换消息，但当我们尝试使用“mod_http_API”API通过 Postman 向客户端发送消息时，我得到的结果是200 ok，但消息没有被传递。
我是否遗漏了使用ejabberd的REST API和postman接收消息的重要内容？
