Monoprice Amp Web Request Help

#1

1) Give a description of the problem
Trying to send a web request that needs a carriage return (\r\n) sent as part of the request and haven’t been successful. Based on the API of the request, it needs to be in plain/text as the content type. This request gets sent over IP and converted to a RS232 connection.

2) What is the expected behavior?
Be able to send a carriage return in the request

3) What is happening/not happening?
I am able to send the command to the API to tun the receiver on/off however, it’s not taking because the carriage return is required for the command to go to the receiver.

In your post request it looks like you’re using single quotes around the \r\n. They should be double quotes I think. At least in normal HTML it is, so I assume it would be the same sending it from webcore.

#3

Either single or double quotes are acceptable… Just be consistent.

If you haven’t tried already, I would try an ‘Expression’ box, and actually press ‘Enter’ where you want the carriage return. (it has to be inside the quotes)

#4

I have tried the expression box as well. I am not sure since the content type is “plain/text” that it’s taking all the characters literally and not recognizing it that it’s a carriage return.
I got it to work through a basic web page POST call but I want to be able to call it through WebCore as part of piston automation and other rules.
