userId 和 Meteor.userId() 在允许/拒绝规则中的区别 [英] Difference between userId and Meteor.userId() in allow/deny rules

问题描述

我有一个集合，其中一些允许规则:

I have a collection and some allow rules on it:

Teams = new Meteor.Collection("teams")
Teams.allow({
    insert: function(userId, doc) {
        console.log(userId);
        console.log(Meteor.userId());
        // do some stuff
    }
})

当我执行 Teams.insert({ name: "superheroes" }) 时，我在控制台中看到 2 个相等的字符串.那么，userId 和 Meteor.userId() 有什么区别?

When I do Teams.insert({ name: "superheroes" }) i see 2 equal strings in console. So, what the difference between userId and Meteor.userId()?

推荐答案

Meteor.userId() 表示当前登录的用户. userId 内允许/deny 规则表示发起操作的用户.由于您不能以其他用户的身份进行方法调用，因此我无法想象这些情况会有所不同.在允许/拒绝规则中检查 userId 真的很常见，所以我认为它被添加为一个参数只是为了方便.

Meteor.userId() means the user which is currently logged in. userId inside of an allow/deny rule means the user that initiated the action. Since you can't make a method call as another user, I can't imagine a situation where these would ever be different. Checking the userId in an allow/deny rule is really common, so I assume it was added as an argument just for convenience.
