Gateway Event Timer sendMessage not work

[471421143]

我通过button onclick运行system.perspective.sendMessage("mapRefresh",payload = {}, scope = "session") 是成功(is ok)的.

I want Periodic refresh sendMessage刷新数据, 但是在Gateway Event Timer 中运行代码则不成效(inoperative).

不知道是什么原因, 请帮助我一下. 谢谢!

Please post your full code as pre-formatted text.

I suspect one reason your 2nd image code isn't working is because it needs indented one tab. An onClick Mouse Event on a button is a function so at the top there will be:

def():
   #put your code here

where you have done:

def():
#your code is here

You can't use system.perspective.sendMessage() outside of Perspective scripts. Gateway events are outside of Perspective. You must use system.util.sendMessage(...., scope='S') to deliver to a perspective session message handler, which can then relay with system.perspective.sendMessage() to the actual perspective scope you wish to target (if not session).

See this discussion:

Set/Configure tag binding with script in Perspective

So, to get this to work I had to make a handler in the project's "Session Events" to receive from system.util.sendMessage(..., scope='S'). It then just calls system.perspective.sendMessage(..., scope='session') with the same payload. The component can receive this latter broadcast. This is a nuance that should be put in the documentation. (That messages broadcast to Perspective via system.util.sendMessage(..., scope='S') can only be received in "Session Events".)

@Matrix_Engineering

indented one tab

谢谢您的回复, 我经过测试不是由于缩进的原因导致的.

谢谢您的帮助, 按照您的提示, 我的问题已经解决了, sendMessage可以正常工作了. 我的解决步骤如下:

1. Gateway Event -->timer 中sendMessage
2. Getway Session Event--->Message中 sendMessage.
3. Vew 中Edit Message Handle接收Recive Message并且执行.

You've put a function in a function. Your def getHostInfo needs indented after def onMessageReceived
