meteor - 是否可以查看所有活动订阅

Question

我有由各种自动运行设置的多个订阅。能够查看在任何给定时间处于活动状态的订阅对于调试目的很有用。这可能吗？

Answer 1

对“活动”订阅一无所知。

但是有一个对象 Meteor.default_connection._subscriptions存储在给定时间之前已订阅的所有订阅的信息。

    var subs = Meteor.default_connection._subscriptions; //all the subscriptions that have been subscribed.

    Object.keys(subs).forEach(function(key) {
        console.log(subs[key]);   // see them in console.
    });

不完全是你想要的。

Answer 2

作为对上述内容的补充，我们可以对它们进行一些组织，以便更容易检查多个订阅等。

//all the subscriptions that have been subscribed.
var subs = Meteor.default_connection._subscriptions; 
var subSummary = {};

// organize them by name so that you can see multiple occurrences
Object.keys(subs).forEach(function(key) {
  var sub = subs[key];
  // you could filter out subs by the 'active' property if you need to
  if (subSummary[sub.name] && subSummary[sub.name].length>0) {
    subSummary[sub.name].push(sub);
  } else {
    subSummary[sub.name] = [sub];
  }
});
console.log(subSummary);

请注意，您可以看到“就绪”状态，以及订阅中使用的参数。
