app.routing.ts中的以下定义：

 [routerLink]="['player-profile',{userID:activity.user.id}]" 

为什么单击routerLink会返回以下错误：

{path:'player-profile/:userID', component: PlayerProfileComponent},

Angular 2 RC.5 +新路由器

Answer 1

仅使用

[routerLink]="['player-profile', activity.user.id]"

该对象用于查询参数。对于路线参数，位置很重要。无需传递名称。
