前端定制开发，预算 300，工作量大概一天

看过一个将 PDF 嵌入到 HTML 的网页：

<!doctype html>
<html data-n-head="">
  <head data-n-head="">
    <title data-n-head="true">PDF System</title><meta data-n-head="true" charset="utf-8"><meta data-n-head="true" name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no,minimal-ui"><meta data-n-head="true" data-hid="description" name="description" content="sample-descripition"><link data-n-head="true" rel="icon" type="image/x-icon" href="/favicon.ico"><link data-n-head="true" rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500,700|Material+Icons"><link rel="preload" href="/_nuxt/c02e8843048f08ed5d11.js" as="script"><link rel="preload" href="/_nuxt/733506230cb54452c0f6.js" as="script"><link rel="preload" href="/_nuxt/01515e5a3b9d60a9d181.js" as="script"><link rel="preload" href="/_nuxt/c407da2b0e33b8054733.js" as="script">

由于我不懂前端的技术细节，但是这个网页就是我想要的：

PDF 直接在网页里面可见
PDF 无法直接下载

除此之外这个小开发还包括：

Single Sign On 页面
使用 AWS S3 文件作为用户数据库
