Meteorhack：集群订阅呼叫失败

Question

I have an UI app on port 8001 and an app named contract on port 7001. I have 'cluster' installed and working. I have a subscription and insert method defined in 'contract' app.

'contract' server/app.js

Cluster.connect("mongodb://<username>:<passwd>@URL");
var options = {
    endpoint: "http://localhost:7001",
    balancer: "http://localhost:7001", // optional
    uiService: "web" // (optional) read to the end for more info
};
Cluster.register("contracts", options);

var Contracts = new Meteor.Collection('contracts');

Meteor.methods({
    addContract: addContract,
    findContracts: findContracts
});

Meteor.publish("getContracts", function () {
    return Contracts.find({});
});

function addContract(c){
    var data = {
        id: c.id,
        type: c.type
    };
    Contracts.insert(data);
}

function findContracts(){
    var contracts = Contracts.find().fetch();
    return contracts;
}

I am accessing the methods from an angular controller in my UI app.

UI app server/app.js

 Cluster.connect(mongodb://<username>:<passwd>@URL"); var options = { endpoint: "http://localhost:8001", balancer: "http://localhost:8001" // optional //uiService: "web" // (optional) read to the end for more info }; Cluster.register("web", options); Cluster.allowPublicAccess("contracts"); 

UI app controller code

 var contractConn = Cluster.discoverConnection('contracts'); contractConn.subscribe('getContracts'); var SubscribedContracts = new Mongo.Collection('SubscribedContracts', {connection: contractConn}); console.log('status', contractConn.status()); vm.contracts = SubscribedContracts.find({}).count(); contractConn.call("findContracts", function(err, result) { if(err) { throw err ; } else { console.log(result); } }); 

This is what is happening: * I can access methods on the contract server * I can insert or find contracts using these methods * My subscription is not working . fetch on the cursor shows 0 and count shows 0 * Status on the connection shows 'connecting'

What am I doing wrong with my subscription?

我必须将客户端mongo集合的名称更改为与服务上的集合名称相同的名称。
