是需要npm i vue-pdf-embed 安装这个插件的，可兼容ios/Android，下面是本人的使用实例

<template><div class="conten_box"><vue-pdf-embed v-if="pdfSource.url" :source="pdfSource" /></div>
</template>
<script setup>
import { onMounted, ref, reactive } from 'vue'
import { ylhtPdf } from "@/api/ht/index";
import VuePdfEmbed from "vue-pdf-embed";const pdfSource = reactive({url: "",cMapUrl: "https://cdn.jsdelivr.net/npm/pdfjs-dist@2.16.105/cmaps/",cMapPacked: true,
});// 获取pdf需要的url
const getInvitation = () => {ylhtPdf().then(({ data: { code, data, message } }) => {pdfSource.url = data.contract;}).catch(() => {});
}onMounted(() => {getInvitation()
})</script>
