我正在使用 Micronaut@Client
调用外部服务,该服务返回我的响应类型FullNettyClientHttpResponse
,它的正文形式为CompositeByteBuf(freed, components=1);
我想转换CompositeByteBuf
为人类可读的toString
消息,但它失败了IllegalReferenceCountException
. 请提供建议我如何在此处获取短信。
@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);
}
}
我尝试使用 toString 获取消息,但因 IllegalReferenceCountException 而失败。
b.toString(Charset.defaultCharset()); // Method threw 'io.netty.util.IllegalReferenceCountException' exception.
toString 返回 CompositeByteBuf。
b.toString(); //CompositeByteBuf(freed, components=1);
