增加一个确认支付的弹窗

修改src\views\orderConfirmation\Order.vue

        <div class="mask__content__btn">确认支付</div>
      </div>
    </div>
  </div>
</template>
<script>
......
</script>
<style lang="scss" scoped>
@import '@/style/viriables.scss';
.order {

          确认支付
        </div>
      </div>
    </div>
  </div>
</template>
<script>
......
</script>
<style lang="scss" scoped>
@import '@/style/viriables.scss';
.order {

    }
    &__btns {
      display: flex;
      margin: 0.24rem 0.58rem;
    }
    &__btn {

      }
      &--second {
        margin-left: 0.12rem;
        color: #fff;
        background: #4fb0f9;
      }
    }
  }
}
</style>

完善按钮逻辑，进入fastmock增加一个post接口/api/createOrder

    /**
     * 输入
     * conten-type：json
     * body:{
       addressId：“xxx”//收货地址 id
       shopId：""//商店id
       shopName:"某什么码1",
       isCanceled:false,//订单是否被取消了
       products:[
       {
         id:"xxx",//商品id
         num:6//商品数量
       }, 
       {
         id:"xxx",//商品id
         num:6//商品数量
       },
       ]
     }
     **/
    {
      "code": 200,
      "data": {   _id: '1',},
      "desc": "成功"
