Closed blue-troy closed 2 years ago

blue-troy commented 2 years ago

this is my demo, i use curl -X POST -H 'Content-Type:application/json' -H 'Accept:application/json' -d '{"workflowdata" : { "action" : "list" , "access" : { "ak" : "aa" , "sk" : "aa" }}}' http://localhost:8080/RestExample to start my workflow instance. want a help to know how to use condition when simple == .
