从Windows服务调用Javascript函数 [英] Call Javascript function from Windows Service

问题描述

大家好，



我有一个在服务器上运行的Windows服务。我有一个html文件（也在IIS上部署，如www.xyz.com/index.html），它有一个javascript库，其中包含带参数的函数。我想通过使用Windows服务的参数调用此JS中的特定函数。是否可以从Windows服务中调用JS函数？给我一些想法.......

推荐答案

你的问题的答案：不，你不能。这有很多原因。


我想假设服务器端有一个事件，来自Windows服务，你想要所有或一些活跃的客户端对此做出反应（例如，通过发送一些尚未发送到服务器端的数据）。 Windows服务永远无法访问客户端。 Web应用程序也不能在iis下托管。但是您的客户端可以针对该特定事件轮询Web应用程序，该事件可以使用某些IPC轮询Windows服务。实际上你也可以公开windows服务，但我不建议这样做。



作为替代 SignalR [ ^ ]是一个很棒的工具，你可以使用，但你仍然需要将客户视为该通信的发起者。

The answer to your question: no, you can't. There are many reasons for that.

Let me suppose that there is an event on server side, comming from the windows service, and you want all or some active clients to react to that (for example by sending some data not yet sent to the server side). The windows service will never be able to access the client. Neither can the web application hosted under iis. But your client can poll the web application for that specific event, which can poll the windows service using some IPC. Actually you could expose the windows service also, but I don't recommend that.

As an alternative SignalR[^] is a great tool you can use, but you still need to think about the client as the initiator of that communication.
