Flow HTTP Server
Title: Inhalt einer Systemvariablen über einfachen Webservice bereitstellen Category: Beispiel Flows
Dieses Beispiel ermöglicht es den Zustand der Systemvariable "Anwesenheit" via HTTP GET abzufragen.
Der Change Node schreibt die Textdarstellung der Variable (wird vom Sysvar Node in der Property valueEnum bereitgestellt) in den Flow Context.
Dieser Change Node überträgt die zuvor im Flow Context gespeicherte Variable in den msg.payload.
Dieser Node beantwortet die HTTP Anfrage
Nun kann http://<ccu-adresse>/addons/red/api/anwesenheit genutzt werden:
