使用路由时从 vuex store 获取特定数据

Question

所以我是 Vue 的新手，过去一两周一直在学习。我似乎无法弄清楚如何获取 PhysicianProfile.vue 组件上的特定医生数据。我在商店中有我的模拟数据，我正在将该信息传递给 PhysicianListing.vue，这是我查看列表的主页（循环遍历数据）。

在 PhysicianFullListing.vue 中，我正在传递一个医生道具，该道具需要一个对象，并且正在 PhysicianListing.vue 上构建列表卡片。我有路由设置来构建我们的 SEO 友好 URL (/physician/profile/firstName-lastName-designation)。

我的问题是如何只取回我当前在个人资料页面上查看的医生的数据？看起来很简单，但我完全错过了我需要做的事情。对此的任何帮助将不胜感激。谢谢。

Answer 1

首先，通过将 props: true 添加到您的路由对象，您可以将路由参数作为 props 传递给您的 PhysicianProfile 组件

    {
        path: '/physicians/profile/:firstName-:lastName-:designation',
        name: 'pd-profile',
        component: PhysicianProfile,
        props: true
    },

然后你可以将这三个道具添加到你的 PhysicianProfile 组件，并设置一个 Vuex getter 来获取医生：

getters: {
  // ...
  getPhysicianByDetails: (state) => (firstName, lastName, designation) => {
    return state.physicians.find(phys => phys.firstName === firstName && phys.lastName === lastName && phys.designation === designation)
  }
}

Answer 2

您可以通过 URL 传递道具，在本例中为医师 ID。然后你可以在创建的生命周期钩子中获取医生 :)

为了使解释更容易一些，我将在您的路径中添加一个 id (/physician/profile/id/firstName-lastName-designation)。您可以更改创建的挂钩中的查找方法以满足您的需要:)

// Router
  {
     path: '/physicians/profile/:id/:firstName-:lastName-:designation',
     name: 'pd-profile',
     component: PhysicianProfile,
     props: true
  },

然后您需要在PhisicianProfile.vue中设置道具并获取医生：

<template>
    <div class="physician-profile">
        <h1 class="mb-5">{{ msg }}</h1>
    </div>
</template>

<script>
    export default {
        name: 'pd-profile',
        props: {
            id: {
                required: true
            },
            // rest of the props if needed
        },
        data () {
            return {
                msg: 'Physician Profile',
            }
        },

        created () {
            // Fetch the physician with based on this.id
            const physician = this.$store.state.physicians.find((physician) => { return physician.id == this.id })
            // Do something with physician (set to data and use in template)
        }
    }
</script>
