您应该在rfc6665 中找到所有答案。您可以更准确地查看4.2.1.4 节。更新订阅和4.4.1节。对话框创建和终止
引用 rfc 的一些文本:
这是从订阅者端请求对话结束的方法:
Clients can cause a subscription to be terminated immediately by
sending a SUBSCRIBE request with an "Expires" header field set to
'0'.
以及真正终止对话的最终通知:
A subscription is destroyed after a notifier sends a NOTIFY request
with a "Subscription-State" of "terminated", or in certain error
situations described elsewhere in this document.
