本地消息传送，请参阅：关闭后重新建立与主机应用程序的连接

问题描述

我有一个功能扩展与本地主机C＃应用程序进行通信。在关闭并重新打开它后，寻找一种方式来自动重新建立与C＃应用程序的连接。任何帮助不胜感激。本地消息传递意味着只有Chrome可以在连接时启动主机实例。 这是一个用词不当，因为 connect（）表示启动一个新的副本并与之通话。

没有办法附加到已经运行的过程。如果关闭主机，stdio管道会破坏 Port 对象触发 onDisconnect 事件。然后，您需要从分机上重新启动主机才能与其通话。

I have a functioning extension that communicates with native host C# app. Looking for a way to automatically re-establish a connection with the C# app after I close and re-open it. Any help greatly appreciated.

解决方案

Native messaging means only Chrome can start a host instance when it "connects". It's a misnomer, since connect() means "launch a new copy and talk to it".

There is no way to "attach" to an already-running process. If you close the host, stdio pipe is broken the Port object fires onDisconnect event. Then you need to re-launch the host from the extension to be able to talk to it.
