tRestRequest attachment_headers variable

_AnonymousUser — Sat, 16 Nov 2024 11:00:58 GMT

Hello,
I want to extract and write in a file the headers of a tRestRequest . I found this :
((java.util.Map<String, java.util.Map<String, java.util.List<String>>>)globalMap.get("tRESTRequest_1_ATTACHMENT_HEADERS"))
My java's expertise is poor so i don't know how to parse this.

firstly, "ATTACHMENT_HEADERS" variable provide headers only for for multipart scenario.

for non-multipart case try following Java code snippet (for example in tJavaRow or tJavaFlex):

javax.ws.rs.core.MultivaluedMap<String, String> allHeaders =
		(javax.ws.rs.core.MultivaluedMap<String, String>)
				 ((java.util.Map<String, Object>) globalMap.get("restRequest")).get("ALL_HEADER_PARAMS");

for (java.util.Map.Entry<String, List<String>> oneHeader : allHeaders.entrySet()) {
	String headerName = oneHeader.getKey();
	List<String> headerValues = oneHeader.getValue();
	// String headerValue = allHeaders.getFirst(headerName); // for single value header
	// ... your code ...
}

i use this in a tJavaFlex :

java.util.Map<String, Object> request1 = (java.util.Map<String, Object>) globalMap.get("restRequest");
System.out.println("HEADERS========>>> " + request1.get("ALL_HEADER_PARAMS"));
