Question

我现在对Meteor很新。

我想

获取网址
检查客户端是否与子域匹配
如果客户端存在，则查询数据库并从数据库中获取一些结果（比如客户端设置）。

我确信如果我们使用MongoDB，这将是一块蛋糕，但是，我们必须移动一个具有MySQL后端的现有应用程序（基于PHP构建）。

我为meteor找到了一个包Bootstrap，我已将它添加到项目中。

这是迄今为止编写的源代码：

if(!Session.get('client_details')) {
    var hostnameArray = document.location.hostname.split('.');

    if(hostnameArray[1] === "localhost" && hostnameArray[2] === "local") {
        var subdomain = hostnameArray[0];
    }

    if(subdomain) {
        currentClientDetails = new MysqlSubscription('getClientDetailsFromUrl', subdomain).reactive();
        Tracker.autorun(function() {
            if(currentClientDetails.ready()) {
                if(currentClientDetails.length > 0) {
                    var clientDetails = currentClientDetails[0];

                    Session.setPersistent('client_details', clientDetails);
                    var clientId = clientDetails.id;

                    if(!Session.get('client_settings')) {
                        clientSettings = new MysqlSubscription('clientSettings', clientId).reactive();
                        Tracker.autorun(function() {
                            if(clientSettings.ready()) {
                                if(clientSettings.length > 0)
                                    Session.setPersistent('client_settings', clientSettings[0]);
                                else
                                    Session.setPersistent('client_settings', {});
                            }
                        });
                    }
                }
            }
        });
    }
}

session.setPersistent来自numtel:mysql以在客户端存储会话 这是发表声明：

Meteor.publish("getClientDetailsFromUrl", function(url) {
    if(typeof url === undefined) {
        return;
    }

    var clientDetails = Meteor.readLiveDb.select(
        'select * from clients where client_url = "'+ url +'"',
        [{table: 'clients'}]
    );

    return clientDetails;
});


Meteor.publish("clientSettings", function(clientId) {
    if(typeof clientId === undefined) {
        throw new error('ClientId cannot be null');
        return;
    }

    var clientSettings = Meteor.readLiveDb.select(
        'select * from client_settings where client_id = ' + clientId, [{
            table: 'client_settings'
        }]);

    return clientSettings;
});

，数据库启动为

Meteor.readLiveDb = new LiveMysql(<MySQL Settings like host, user, passwords, etc>);

问题

我成功地将client_details加入会话，然而，无法将client_settings加入会话。最终出现错误：

Exception from Tracker recompute function:
Error: Subscription failed!
    at Array.MysqlSubscription (MysqlSubscription.js:40)
    at app.js?6d4a99f53112f9f7d8eb52934c5886a2b7693aae:28
    at Tracker.Computation._compute (tracker.js:294)
    at Tracker.Computation._recompute (tracker.js:313)
    at Object.Tracker._runFlush (tracker.js:452)
    at onGlobalMessage (setimmediate.js:102)

我知道代码很乱，可以好多了，欢迎提出建议
