如何将参数传递给Vue组件？

<template>
  <div>
    <child-component :message="message"></child-component>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello World'
    }
  }
}
</script>

<template>
  <div>
    <p>{{ message }}</p>
  </div>
</template>

<script>
export default {
  props: {
    message: String
  }
}
</script>

<template>
  <div>
    <child-component :message="message"></child-component>
  </div>
</template>

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

export default {
  components: {
    ChildComponent
  },
  data() {
    return {
      message: 'Hello World'
    }
  }
}
</script>
