How can i use the injector topic in the url http request node ? this topic containts the id(example 1002) i use in the url http://192.168.20.35:82/json.htm?type=devices&rid=1002

Perhaps this thread can clarify [image] HTTP request node - query string General The http request node was greatly improved in Node-REd version 0.20 with the addition of Bearer and Digest authentication modes. Additionally, a new option was added to allow building a query…

Solved it http://192.168.20.35:82/json.htm?type=devices&rid={{payload} } and in the injector node i use the payload for the content

Last and most difficult part of my flow is to get the name of the device as a property in my payload.. Do i have to write complex scripts or is there an easier way? This is my data from the http url (i need "Name" : "lantaarn") { "ActTime" : 1576067493, "AstrTwilightEnd" : "18:36", "AstrTwilig…

Change node with JSONata would be my first suggestion. Or just a change node as it isn’t that exciting. Try set msg.payload to msg.payload.result[0].Name

I think it works I made a function with msg.payload.naam = msg.payload.result[0].Name return msg;

I finished my function and get the following error: "TypeError: Cannot read property '0' of undefined" This is the function msg.payload = {} msg.payload.naam = msg.payload.result[0].Name msg.payload.id = msg.payload.result[0].idx msg.payload.state = msg.payload.result[0].Status return msg;

I think i killed the message before reading it.. This is better name = msg.payload.result[0].Name state = msg.payload.result[0].Status idx = msg.payload.result[0].idx msg.payload = {}; msg.payload.naam = name msg.payload.state = state msg.payload.idx = idx return msg; thank yoy very much @…

You can simplify it a bit more, yet keep readability: var payload = { naam: msg.payload.result[0].Name, state: msg.payload.result[0].Status, idx: msg.payload.result[0].idx }; msg.payload = payload; return msg;
