nodejs通过thrift进行跨语言请求java，默认的协议可以，如何使用TMultiplexed协议进行通讯？

服务端代码 public class ThriftServer {

private final static int PORT_TMULTIPLEXED = 9980;
private final static int PORT_DEFAULT = 9981;

public static void main(String[] args) {
	new Thread(new TypeTmultiplexed()).start();
	new Thread(new TypeDefault()).start();
}

static class TypeTmultiplexed implements Runnable{
	
	public void run() {
		try {
			LogCvt.info("thrift service (Tmultiplexed) init complete port: " + PORT_TMULTIPLEXED);
			TMultiplexedProcessor processor = new TMultiplexedProcessor();
			TServerTransport t = new TServerSocket(PORT_TMULTIPLEXED);
			TServer server = new TThreadPoolServer(new TThreadPoolServer.Args(t).processor(processor));
			processor.registerProcessor(CaseThriftService.class.getName(), processor);
			server.serve();
		} catch (TTransportException e) {
			e.printStackTrace();
		}
	}
}

static class TypeDefault implements Runnable{
	public void run(){
		try {
			LogCvt.info("thrift service (Default) init complete port: " + PORT_DEFAULT);
			TServerSocket serverTransport = new TServerSocket(PORT_DEFAULT);
			CaseThriftService.Processor<?> processor = new Processor<>(new CaseThriftServiceImpl());
			Factory portFactory = new TBinaryProtocol.Factory(true, true);
			Args args = new Args(serverTransport);
			args.processor(processor);
			args.protocolFactory(portFactory);
			TServer server = new TThreadPoolServer(args);
			server.serve();
		} catch (TTransportException e) {
			e.printStackTrace();
		}
	}
}

}

如上，用java启动了两个thrift的服务器分别监听着9980 9981 端口，其中9980是使用的thrift中协议为：Tmultiplexed 的方式，9980则使用的是默认的协议

服务端启动完毕..........................

客户端nodejs代码 var thrift = require('./node_modules/thrift');

var transport = require('./node_modules/thrift/lib/thrift/transport');

var service_api = require('./sample/gen-nodejs/CaseThriftService'); var server_type = require('./sample/gen-nodejs/Tserver_types');

var connection_def = thrift.createConnection("localhost", 9981); connection_def.on('error', function(err) { if(err != null){ console.log(err); return; } }); var client_def = thrift.createClient(service_api, connection_def); client_def.ping('connection to server',function (err,response){ if(err != null){ console.log(err); return; } console.log('service response msg: ' + response); var case_type = new server_type.CaseVo({ argStr:'typeOf String', argInt: 1000 }); client_def.doCase(case_type,function(err,response){ if(err != null){ console.log(err); return; } console.log('service response msg: ' + JSON.stringify(response)); }); connection_def.end(); });

使用nodejs 中thrift模块 进行通讯，首先请求9981端口 ----------------- > 通讯正常 再将端口换成9980 -----------------> 服务端异常显示错误信息

很明显服务端需要使用TMultiplex协议，但是我并不知道nodejs 中thrift 是用TMultiplex协议如何请求，不知道有没有大神解答下？
