vue3如何在setup函数中利用props接收父组件传值给子组件

props.get_content是undefined，是哪里没写对大家可以指点一下嘛
父组件

<template>
  <div id="home">
    <Nav @get_nav="nav" />
    <Content :get_content="text" />
  </div>
</template>

<script>
import Nav from "@/components/Nav.vue";
import Content from "@/components/Content.vue";
import {ref} from 'vue'

export default {
   name: "Home",
   components: {
    Nav,
    Content,
    },
  setup(props,context){
    // 响应式文本
    let text = ref("")
    let nav = (response) => {
      console.log("子传父,接收内容:" + response);
      text = "这是:"+response;
      console.log("父传子,传递内容:" + text);
    }
    // 把定义的内容暴露出去
    return{
      nav,
    }
  }
};
</script>

子组件

<template>
  <div id="content">
    <p>{{get_content}}</p>
  </div>
</template>

<script>
export default {
  name: "Content",
  // 接收父组件传递的参数
  props:{
      get_content:String,
  },
  setup(props,context) {
    // 接收父组件传递的参数
    console.log("props:" + props.get_content);
    
  },
  
};
