http.onrequest(requestHandler);

Agent Code
1

Hello,

I am encountering a weird thing going on with GET vs POST request. I have the following agent code:

`
function requestHandler(request, response) {
try {
// check if the user sent Hardware_Reset as a query parameter
server.log(“All good - 1”);
// if (“Test1” in request.query)
if (“Test1” in request.query)
{
server.log(“All good - 2”);
if (request.query.Test1== “0” || request.query.Test1 == “1”)
{
server.log(“All good - 3”);
}
}
// send a response back saying everything was OK.
response.send(200, “OK”);
} catch (ex) {
response.send(500, "Internal Server Error: " + ex);
}
}

// register the HTTP handler
http.onrequest(requestHandler);
`

Now, if I go to the internet and type the following into the web browser:
https://agent.electricimp.com/MYAGENTLINK?Test1=0

I get the following output in the server logs: This is a GET request
All good - 1
All good - 2
All good - 3

Now if I use a perl program to do the same thing, I only get the following output:
All good - 1

This is the perl program that I am using:
`
#************************************************
#**************** Send_Request********************
#************************************************
sub Send_Request
{
use HTTP::Request::Common qw(POST);
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;

my $url = 'https://agent.electricimp.com/'.$Agent_Link;
    my $req = ('Garage_Door_ID' => '0'); 
   
    my $response = $ua->post($url,$req);

Check the response

if ($response->code() == 200)	#$response->code will return 200 for OK (this is set within the IMP Agent Code)
	{		
    print $response->code();		#Change this line of code to do whatever I want
	 }
}

1;
`

So why is the “All good -2” and “All good -3” dropping out from the POST request, but not the GET request. How do I make this work with the POST request?

Thanks

Have you read this imp blog as it demos post method: https://community.electricimp.com/blog/how-to-serve-an-html-form-via-an-agent-and-deal-with-the-results/

If I’ve read your Perl code right, it’s not sending the equivalent of ?Test1=0 to the agent, so the agent prints the first message (on receipt of the request) but not the others (request lacks the strings being checked for), ie. ("Test1" in request.query) fails. The incoming request parameter in requestHandler() is a table, so you can check for the POST request by examining request.method
