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>
