Question

我无法通过路由器上的 Meteor.call 验证用户。只有 return "undefined" pr

"Exception in delivering result of invoking 'verifyUserRole': TypeError: undefined is not a function"

Router.route("/admin", function(){
    Meteor.call("verifyUserRole", function(error, result){
        if(result){
            this.render('adminDashboard');
            this.layout("adminLayout");
        } else {
            this.render('adminLogin');
        }
    })
});

 Meteor.methods({
   "verifyUserRole" : function(){
       if(this.userId){
       var user = Meteor.user();
       var role = user.profile.role;
       if(role == "admin"){
           return true;
       } else {
           Session.set("adminLoginError", "Restrict Area");
           return false;
       }
   }
}});

this 的值是指您的内部函数而不是外部函数。尝试以下操作：

Router.route("/admin", function(){
  var self = this;
  Meteor.call("verifyUserRole", function(error, result){
    if(result){
      self.render('adminDashboard');
      self.layout("adminLayout");
    } else {
      self.render('adminLogin');
    }
  });
});
