错误:尝试连接到远程gremlin服务器(TinkerPop3)时连接ECONNREFUSED

Question

我使用gremlin-javascript模块访问远程gremlin服务器.我在app.js中的代码:

var gremlin = require('gremlin-client');
var client = gremlin.createClient(8182, 'localhost');
var query = client.stream('g.V()');
query.on('data', function(result) {
  console.log(result);
});
query.on('end', function() {
  console.log("All results fetched");
});

这工作正常,所有查询都在执行.但当我用我的远程服务器地址--cbtitan.cloudapp.net替换'localhost'时,它会回复ECONNREFUSED错误.

我应该更改/做什么来连接到该远程服务器？或者我应该更改该远程服务器中的任何配置？我严重困扰这个问题,请帮帮我.提前致谢.

在gremlin-server.yaml,你需要做一些改变.

您需要更新主机.默认值为localhost,这意味着您只能从本地客户端进行连接.您应该使用机器的IP地址,或者如果要在所有接口上侦听,则应使用0.0.0.0.

host: 0.0.0.0

您应该使用WebSocketChannelizer而不是HttpChannelizerwith,gremlin-javascript因为它是TinkerPop3 Gremlin Server的WebSocket JavaScript客户端.

channelizer: org.apache.tinkerpop.gremlin.server.channel.WebSocketChannelizer
