【问题描述】：
大家好，我正在尝试从 Java 应用程序发送 xmpp 消息。我已经在 ejabberd 中配置了 mod_rest。 Java发送xmpp消息的方法如下：
public String sendmessage() {
String response = null;
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_XML);
String xmppMessage = "<message from='user1@<ip>'"+
" to='user2@<ip>'"+
">"+
"<body>Hello</body>"+
"</message>";
headers.set("Host",ip+":"+port);
headers.set("Accept-Charset","*/*");
headers.setContentType(MediaType.APPLICATION_XML);
HttpEntity<String> request = new HttpEntity<String>(xmppMessage,headers);
response = restTemplate.postForObject("http://ip:port/rest", request, String.class);
return response;
}
当我收到 HTTP 406 错误时：
Jun 23, 2016 11:32:14 AM org.springframework.web.client.RestTemplate handleResponseError
WARNING: POST request for "http://ip/rest" resulted in 406 (Not Acceptable); invoking error handler

在 ejabberd.log 中出现匹配错误

消息的格式有什么问题或缺少什么吗？ 非常感谢大家的帮助

【问题讨论】：
-
为什么不使用 send_message 方法发送它而不是发送 xml 节
-
只需检查是否可以使用 ejabberdctl 命令中的 send_message。如果是，那么您可以使用它来满足您的要求。
