I have been using the http-request node successfully (including authentication of the device). I now want to send another command (payload) but due to how it is formatted do not get it working.
The call to be executed:
http://<IP>/rpc/Cover.SetConfig?id=0&config={in_mode:%22detached%22}
works like this when using a browser. So the call basically is correct.
In node red I'm calling the http-request node with the payload providing the data as params (works this way for other commands):
I get the following reply:
The issue here is that the config data is provided in {} which gets reformatted when sending this payload to the http-request node.
The config part should stay like config={in_mode:%22detached%22} and should not be formatted.
Any idea how to solve this? Any escape characters that I can use? I tried {{{}}}, \{\}, but nothing did the trick.
The simplest method would be to put it together in a function node (or template node)
Function e.g.
msg.url = 'http://<IP>/rpc/Cover.SetConfig?id=0&config={in_mode:%22detached%22}'
return msg
NOTE: for this to work, you need to leave the http url field blank.
Read the built in help for the http node for more info
I think I need to send the parameter as POST body together with the authentication, which is what I'm currently doing. But I suspect that the nested {} cause issues here.
I tried as you explained already, but it did not work. I think the authentication part was then not accepted anymore. I somehow need to send it as is in the params.
Not sure I follow.
If you are doing POST then simple put the JS object directly into msg.payload.
Are there other/additional data (different from this config and id you mention in The URL) that needs to be sent as POST data?

{in_mode:%22detached%22} in_mode would require quotes also.
If you post this then config would need to be a valid json or a javascript object

Thanks to both of you. I just tried what @E1cid mentioned and it seems to work.
