Angular2路由，路由參數

Question

我有問題，一些問題上angular2路由參數應用，則params是不確定的，我將向這個項目的一些代碼： 它route.module

import { NgModule } from '@angular/core'; 
import {RouterModule, Routes} from '@angular/router'; 
import {StudentRegisterComponent} from './student-register/student-register.component'; 

const routes: Routes = [ 

    { path: 'student/register', component: StudentRegisterComponent }, 
    { path: 'student/register/:token', component: StudentRegisterComponent } 
]; 

@NgModule({ 
    imports: [ 
     RouterModule.forChild([ 
      { path: 'student/register', component: StudentRegisterComponent } 
     ]) 
    ], 
    exports: [RouterModule] 
}) 
export class StudentRoutingModule { } 

和組件文件：

import { Component, OnInit } from '@angular/core'; 
import { Http } from '@angular/http'; 
import {Router, ActivatedRoute, Params} from '@angular/router'; 
@Component({ 
    moduleId: module.id.toString(), 
    selector: 'student-register', 
    templateUrl: 'student-register.component.html' 
}) 
export class StudentRegisterComponent { 
constructor(private activatedRoute: ActivatedRoute 
    ) 
ngOnInit() { 
    // subscribe to router event 
     let param1 = this.activatedRoute.snapshot.params['token']; 
     console.log('params: ' + param1); 
} 
} 

有什麼辦法可以工作嗎？

您沒有使用在指定了token您Routes對象：

試試這個：

import { NgModule } from '@angular/core'; 
import {RouterModule, Routes} from '@angular/router'; 
import {StudentRegisterComponent} from './student-register/student-register.component'; 

const routes: Routes = [ 

    { path: 'student/register', component: StudentRegisterComponent }, 
    { path: 'student/register/:token', component: StudentRegisterComponent } 
]; 

@NgModule({ 
    imports: [ 
     RouterModule.forRoot(Routes) 
    ], 
    exports: [RouterModule] 
}) 
export class StudentRoutingModule { }
