Question

我正在尝试运行https://github.com/hazelcast/hazelcast-nodejs-client

的“使用客户端”部分中提供的基本示例代码

我收到连接拒绝错误。我在我的Mac和我的PC机上尝试了相同的结果。他们正在运行Node v6.9.1。我没有任何特殊的防火墙设置。甚至尝试完全转向Windows防火墙。

我有什么遗失的吗？

[DefaultLogger] WARN at ClientConnection: Could not connect to address localhost:5701

首先我创建了一个空节点项目：

npm install hazelcast-client --save

然后用：

创建了一个js文件

var HazelcastClient = require('hazelcast-client').Client;
var person = {
    firstName: "Joe",
    lastName: "Doe",
    age: 42
};
var map;
HazelcastClient.newHazelcastClient().then(function (hazelcastClient) {
    map = hazelcastClient.getMap("personMap");
    map.put(1, person).then(function (val) {
        // prints previous value for key `1`
        console.log(val);
    });
    map.get(1).then(function (value) {
        console.log(value);
    })
});

这就是所有文件都要做的。使用hazelcast-client for nodejs是否需要在localhost上启动单个客户端集群？

开始之前

从https://hazelcast.org/download/
解压缩到任何文件夹
使用启动脚本/bin/start.sh启动Hazelcast成员
- 您现在可以使用样本

start hazelcast node http://gamov.io/images/before_nodejs_client.gif

让我知道它是否有效
