Question

需要一些建议。

这是我从node.js开始的示例：

  var amqp = require('amqplib');

    amqp.connect('amqp://localhost:61616').then(function(conn) {
      conn.once('SIGINT', function() { conn.close(); });
      return conn.createChannel().then(function(ch) {
        var ok = ch.assertQueue('xxx', {durable: true});
        ok = ok.then(function() { ch.prefetch(1); });
        ok = ok.then(function() {
          ch.consume('xxx', doWork, {noAck: false});
          console.log(" [*] Waiting for messages. To exit press CTRL+C");
        });
        return ok;

        function doWork(msg) {
          var body = msg.content.toString();
          console.log(" [x] Received '%s'", body);
          var secs = body.split('.').length - 1;
          //console.log(" [x] Task takes %d seconds", secs);
          setTimeout(function() {
            console.log(" [x] Done");
            ch.ack(msg);
          }, secs * 1000);
        }
      });
    }).then(null, console.warn);

ActiveMQ写入以记录此信息：

WARN  | Transport Connection to: tcp://127.0.0.1:34186 failed: java.io.EOFException | org.apache.activemq.broker.TransportConnection.Transport | ActiveMQ Transport: tcp:///127.0.0.1:34186@61616

我认为，这个错误是因为61616端口的协议是tcp，而不是amqp。但是当我尝试在控制台输出中将端口更改为5672时，我看到了：

netstat -antp返回：

正如你所看到的，ActiveMQ在5672上听...但是，不要连接。为什么？？？我尝试其他node.js模块，如node-amqp.js，没有任何改变。可能是我想念connection_tunnig中的一些东西？（frameSize等）请，真的需要建议。谢谢。

从快速Google搜索中我可以看出，node_amqp.js是针对AMQP规范0.9.1编写的，而ActiveMQ是为了实现AMQP v1.0，因此您将无法通过该客户端进行连接。您需要使用符合AMQP v1.0的客户端库连接到公开的AMQP传输端口上的ActiveMQ。

Node.js + node_amqp.js无法连接到ActiveMQ 61616或5672端口
