流星的铁路由器-路由前更改路径 [英] Meteor's Iron Router - Alter Path before routing

问题描述

在基于某种逻辑(例如Session变量)路由页面之前，是否可以更改路径?例如:

Is there a way to change the path before the page is routed based on some logic, such as a Session variable? For example:

// Before routing
Router.onBeforeAction(function () {
    if(Session.get('key') === true) {
        prependToPath('prefix');
    }
});

推荐答案

您可以使用Iron.Location.get().path获取当前路径，运行逻辑，然后在Router.go()中使用新路径.像这样:

You can get the current path using Iron.Location.get().path, run through your logic, and then use the new path in Router.go(). Like so:

// If abc is set on the URL, then keep it there
if (Session.get('abc') === true) { // You can use better logic here
    Router.go('/abc' + Iron.Location.get().path);
}

，并确保您Session.set('abc') = false在某个地方，否则它将继续循环，在无限循环中添加/abc.

and make sure you Session.set('abc') = false somewhere or else it will keep on looping, adding /abc in an infinite loop.
