Php 发送帧在事务中失败（STOMP）

php transactions

Php 发送帧在事务中失败（STOMP）,php,transactions,stomp,apollo,Php,Transactions,Stomp,Apollo,我正在为STOMP（Apollo）制作自己的PHP网关，因为所有现有的解决方案要么太糟糕，要么太复杂 因此，当我在没有事务（但有收据）的情况下向队列发送消息时，一切正常，请参阅日志： SEND destination:/queue/teststst content-type:text/plain content-length:100 receipt:f1dd03450508d938e6eb8196a6d128c4 2149b4a936862b121f7928ed5c060152 75235e0

我正在为STOMP（Apollo）制作自己的PHP网关，因为所有现有的解决方案要么太糟糕，要么太复杂

因此，当我在没有事务（但有收据）的情况下向队列发送消息时，一切正常，请参阅日志：

SEND
destination:/queue/teststst
content-type:text/plain
content-length:100
receipt:f1dd03450508d938e6eb8196a6d128c4

2149b4a936862b121f7928ed5c060152
75235e0fbc8a56970ede75d2147b538b
fece2e4403b52fd903b8e7a78b1918c6

RECEIPT
receipt-id:f1dd03450508d938e6eb8196a6d128c4
但当涉及到事务时，我得到了以下信息（我删除了握手日志，不用担心）：

然后什么也没有。我的包装器尝试接收接收帧，但只有一个fgets超时，看起来代理等待更多发送帧数据，但生成帧的过程是相同的，只有一个标头（事务）。所有必要的EOL和空八位字节都已就位

解决了它。如果启动事务，则不需要收据标题，因此必须修复官方STOMP文档（可能是与阿波罗相关的问题）。
是否确实发送STOMP提交框架？在相关交易提交之前，接收者不会收到交易发送帧。
请用英语回答。我不太确定这是关于PHP的，它更多的是关于跺脚本身。再说一次：完全没有区别，只是多了两个帧（begin和commit/abort）和帧中的一个事务头。基本上你的PHP在哪里？这被标记为一个PHP问题，所以我希望看到一些代码。我认为这比PHP更像是STOMP协议问题。好吧，让我们看看我们能做些什么。好吧，看来readFrame中的这段代码永远不会在无限循环中执行，是吗？elseif（$state===static:：state_BODY&&$this->detectNullOctet（$frameLine））{break；}
