how to realise this function?
two nodes(TO and TS) conmunication by service and topic,how to realise this :
TO TS
--------requst-----> #this is a service ,TO as client,TS as server
<-------response----
<-------requst------ #another service,TS as client,TO as server
-------response---->
-------topic--------> # TO as publisher,TS as subscriber
here,two nodes communicate during a time,they run in order, I have no idea to edit
...I don't understand which part of this is your question.
nodes communicate in different.for example,when this service run over,the node judge if will run the next service.
