接收了参数并且获取了相应的数据。
这里在 onLoad 周期中进行获取和调用函数，因为其他部分执行在onload之前，如果在onload之外调用函数，queryParams 还没有获取到id和name。

<template>
	<view class="classlist">
		<view class="content">
			<navigator url="/pages/preview/preview" class="item" v-for="item in classList" :key="item._id">
				<image :src="item.smallPicurl" mode="aspectFill"></image>
			</navigator>
		</view>
	</view>
</template>

<script setup>
	import {
		ref
	} from 'vue'
	import {
		apiGetCLassList
	} from '@/api/apis.js'
	import {
		onLoad
	} from '@dcloudio/uni-app'

	const queryParams = {}

	onLoad(e => {
		console.log(e)
		let {
			id = null,
				name = null
		} = e
		uni.setNavigationBarTitle({
			title: name
		})
		queryParams.classid = id

		getClassList()
	})

	const classList = ref([])

	const getClassList = async () => {
		let res = await apiGetCLassList(queryParams)
		console.log(res)
		classList.value = res.data
	}
</script>

<style lang="scss">
	.classlist {
