Vue模拟数据,实现路由进入商品详情页面的示例

 {
  path: '/goodDetail',
  component:goodDetail
 }

//点击路由到商品详细信息页
  selectGood(){
  router.push({
   path: 'goodDetail',
   query:{goodId:this.goodDetail.id}})
  }

export default{
 data(){
  return {
  id: this.$route.query.goodId,
  loading: false,
  selectedGood: []
  }
 },

 created(){
  this.fetchData();
 },

 methods:{
  fetchData(){
  this.loading = true;

  //拿到查询字段，商品的id后进行http请求
  var id = this.id;
  this.$http.get('/api/goods/' + id)
   .then(response => {
   this.selectedGood = response.data.data;
   }, error => {
   console.log(error);
   })

  this.loading = false;
  }
 }
 }

//获取mock数据
var appData = require('../data.json');
var goods = appData.goods;

var apiRoutes = express.Router();

apiRoutes.get('/goods', function (req, res) {
 res.json({
 errno: 0,
 data: goods
 });
})

//拿到指定id的商品信息
apiRoutes.get('/goods/:id', function(req, res) {
 var id = req.params.id;
 function selectedGood(id){
 for(var i = 0; i < goods.length; i++) {
  if(goods[i].id == id){
  return goods[i];
  }
 }
 }
 var good = selectedGood(id);
 res.json({
 errno: 0,
 // data: goods[req.params.id]
 data: good
 });
})

app.use('/api', apiRoutes);
