如何在Vue.js中使用对象道具？

<template>
  <div>
    <ChildComponent :user-info="userInfo" />
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent
  },
  data() {
    return {
      userInfo: {
        name: 'John Doe',
        age: 30,
        email: 'john.doe@example.com'
      }
    };
  }
};
</script>

<template>
  <div>
    <p>Name: {{ userInfo.name }}</p>
    <p>Age: {{ userInfo.age }}</p>
    <p>Email: {{ userInfo.email }}</p>
  </div>
</template>

<script>
export default {
  props: {
    userInfo: {
      type: Object,
      required: true
    }
  }
};
</script>

props: {
  userInfo: {
    type: Object,
    required: true,
    validator: function(value) {
      return value.name && value.age && value.email;
    }
  }
}

import _ from 'lodash';

export default {
  methods: {
    updateUserInfo() {
      const newUserInfo = _.cloneDeep(this.userInfo);
      newUserInfo.name = 'Jane Doe';
      this.$emit('update:user-info', newUserInfo);
    }
  }
};
