有两种方案
1.通过kkfile后端服务调用，实现，后端部署服务，前端传递网络地址pdf

//KKFILE_URL 是后端服务地址
export function kkfilePreview(url) {// 修改kkfile文件预览，需要进行base64编码return KKFILE_URL + '/onlinePreview?url=' + encodeURIComponent(Base64.encode(url))
}

2.通过vue2-pdf-embed，来浏览pdf

<template><div><vue-pdf-embedsource="pdf网络地址" /></div>
</template><script>import VuePdfEmbed from "vue-pdf-embed/dist/vue2-pdf-embed";export default {components: {VuePdfEmbed,},data() {return {}},}
</script>
