Hi , Does the Http Request ( input ) work like it says in its own documents ?
1/ It say , if you name a topic it will add it to the url string , but I can get that to work.
if I name a topic of a injecting "data" and set the url to 127.0.0.1/1880 all I get is the node-red admin page.
2/ it say , to pass a request headers key pair feed in a msg.header , I can get GET or POST to work , the only way I`ve found is to use a GET form type push eg 127.0.0.1:1880?what=ever
I`ve posted my flow on how I've set them up
Thanks in advance Peter
