我正在从Meteor 8.2更新到Meteor 1.0。我删除了所有旧的陨石包并安装了相关的流星包系统包。我不得不安装新的铁路由器包，我在流星运行的控制台中收到以下错误：
路线调度从未呈现过。您是否忘记在onBeforeAction中调用this.next（）？
包的迁移说明说：“onBeforeAction钩子现在要求你调用this.next（），而不再使用pause（）参数。”
我尝试通过从函数中删除pause并在this.next();语句后添加else来关注该示例，但无济于事。
如何编辑我的路由器以便它使用新的onBeforeAction挂钩？此外，您可以从可能存在问题的迁移中调出的任何其他内容将非常感激。谢谢！
这是我的路由器文件：

答案 0 :(得分：1)
新的onBeforeAction挂钩必须调用this.next（）;你必须在每个onBeforeAction中调用它。例如，新Iron Router中的管理路由如下所示：
Router.route('/admin', {
name: 'adminView',
onBeforeAction: function () {
var user = Meteor.user();
if (!user || !user.admin) {
this.render('home');
}
this.next();
}
});
用Router.route（'/ path'，options）替换Router.map中的所有this.route（...）并删除Router.map（）
您的全球onBeforeAction将如下所示：
Router.onBeforeAction(function() {
Alerts.clearSeen();
this.next();
});
此外，您不需要在Meteor.startup（...）中包装路由。你可以删除它。
并且没有暂停参数，而不是暂停调用this.next（）外部条件：
var filters = {
nProgressHook: function () {
// we're done waiting on all subs
if (this.ready()) {
NProgress.done();
} else {
NProgress.start();
}
this.next();
}
};
Router.onBeforeAction(filters.nProgressHook);
