I am using Micronaut @Client to call external service which returns me response
of type FullNettyClientHttpResponse and it has body in the form of CompositeByteBuf(freed, components=1); I want to convert CompositeByteBuf to a human readable toString message but it has failing with IllegalReferenceCountException. Please provide suggestion how I can get the text message here.
@Client(value = "url")
public interface MyClient {
@Post(consumes = MediaType.APPLICATION_XML, produces = MediaType.APPLICATION_XML)
HttpResponse call(String body);
}
class service{
void method(){
HttpResponse httpResponse = client.call(request);// returns FullNettyClientHttpResponse with body "Optional[CompositeByteBuf(freed, components=1)]"
Optional<CompositeByteBuf> reBody = httpResponse.getBody(CompositeByteBuf.class);
if(reBody.isPresent()){
CompositeByteBuf b=reBody.get();
byte[] req = new byte[b.readableBytes()];
b.readBytes(req);
String body = new String(req, CharsetUtil.UTF_8).substring(0, req.length -
System.getProperty("line.separator").length());
System.out.println("server receive order : " + body);
}
}
I tried to get the message using toString but failed with IllegalReferenceCountException.
b.toString(Charset.defaultCharset()); // Method threw 'io.netty.util.IllegalReferenceCountException' exception.
toString returns CompositeByteBuf.
b.toString(); //CompositeByteBuf(freed, components=1);
You must specify the body type in the client if you want micronaut to keep the body of the response.
For example:
HttpResponse<String> call(String body);
