Right way to do url-encoded requests with Apama in C8Y?

Hi,

I am trying to do a POST request with url-encoded parameters (specifically application/x-www-form-urlencoded) and I am struggling to get a valid response.

I am always getting such an error:

com.softwareag.connectivity.httpclient.Response("POST","/xxx",com.apama.util.AnyExtractor(any()),400,"No message received: ",com.softwareag.connectivity.httpclient.HttpOptions({},{},{}),522)

Using other tools, I can confirm that that the API is working in general. From the error code (400), I suspect this error is not actually produced by the server but internally in Apama.

This is my latest attempt:

		HttpTransport transport := HttpTransport.getOrCreateWithConfigurations("...", 443, config);
		dictionary<string, string> payload := {
		... removed ...
		};
	    dictionary<string, dictionary<string, string>> formMetadata := new dictionary<string, dictionary<string, string>>;		
    	HttpOptions httpOptions := new HttpOptions;
    	httpOptions.headers["content-type"] := "application/x-www-form-urlencoded";
    	FormRequest(
        	transport.createRequest(RequestType.POST, "...", payload, httpOptions),
        	formMetadata).execute(handleResponse);

I also tried it directly with a Request both putting the query parameters into the payload and by explicitly setting query parameters using setQueryParameter.

Any idea what I am doing wrong? Is there a good way to get to the actual error?

Can you check if the following documentation helps?

Hi Sandeep,

thank you but this is where I got my code from. Can you confirm if my suspicion is correct that the “400” code I am getting is indeed produced by Apama (Connectivity plugin) and not by the server? If I am trying to emulate the error condition by sending an empty form via a standalone HTTP client I am getting a different error and I doubt that the server would use a generic “400” code.

Resolved the issue. While I specified port 443 or HTTPS, I did not explicitly activate TLS:

dictionary<string, string> config := {"tls":"true"};
