Is there a way to customize the response for a POST request to HTTP IN?
Right now I’m only getting an OK, but I’d like to get a different response if, for example, my impee is offline.
This functionality is available with agents (in beta right now) and the http.onrequest function.
If you like, I can set you up on our beta, and you can give it a try 
Edit: included link to devwiki page.
on the forum I found an example for use with Agents but I can’t find it anymore, so here is my version. You have to create you web app yourself but for testing I go to http://hackst.com/
Agent:
`server.log("access me via "+http.agenturl());
local YellowState = 0;
local RedState = 0;
device.on(“setRed”, function(data) {
RedState = data;
});
device.on(“setYellow”, function(data) {
YellowState = data;
});
http.onrequest(function(request, response) {
server.log("http.onrequest received ");
local code = null;
local message = null;
server.log("request.path: " + request.path);
if (request.path == “/lights”){
if (request.method == "GET"){
code = 200;
message = "{ 'Red': " + RedState + ", 'Yellow': " + YellowState + " }";
}
else if (request.method == "POST"){
try {
local data = http.jsondecode(request.body);
if ("Red" in data){
//server.log("Red: " + data.Red);
device.send("setRed", data.Red);
}
if("Yellow" in data){
//server.log("Yellow: " + data.Yellow);
device.send("setYellow", data.Yellow);
}
code = 200;
message = "OK";
}
catch (e) {
code = 501;
message = "Unacceptable";
server.log(e);
}
}}
else{code = 404; message = "Not Found";}
response.send(code, message);
});`
Device:
`
class LEDController{
pin = null;
colour = null
state = 0;
constructor(ledPin, ledColour){
pin = ledPin;
colour = ledColour;
pin.configure(DIGITAL_OUT);
}
function TurnOn(){
Write(0);
}
function TurnOff(){
Write(1);
}
function Write(newState){
server.log("Write called");
if (newState == 0 || newState == 1)
{
state = newState;
server.log(colour + ": " + newState);
agent.send("set" + colour, newState);
pin.write(newState);
}
else
{
server.log(newState + " is not a valid LED state. Please use 0 or 1.");
}
}
};
local RedLED = LEDController(hardware.pin8, “Red”);
local GreenLED = LEDController(hardware.pin9, “Yellow”);
//RedLED.TurnOff();
//GreenLED.TurnOff();
agent.on(“setYellow”, function(state) {
GreenLED.Write(state);
});
agent.on(“setRed”, function(state) {
RedLED.Write(state);
});
imp.configure(“Red Light Yellow Light”,[],[]);`
In this example I would not use HTTP IN’s URL ?
I would use instead http.agenturl() to post?
Correct - you would use the url that http.agenturl() returns.
You can also find the agent URL by clicking on “Device Settings.”
I would like to use http.onrequest function in my imp.
Connect this function, please
I see my imp dont connection with site!!! I cant download device program
