一、前情提要
1. 需求
仿照e签宝，实现pdf电子签章 => 拿到pdf链接，移动章的位置，获取章的坐标
技术 : 使用fabric + pdfjs-dist + vuedraggable
2. 借鉴
一位大佬的代码仓亏 : 地址
一位大佬写的文章 ：地址
3. 优化
在大佬的代码基础上，进行了些许优化，变的更像e签宝
二、下载
ps : 怕版本不同，导致无法运行，请下载指定版本
1.fabric
fabric :是一个功能强大且操作简单的 Javascript HTML5 canvas 工具库
npm install fabric@5.3.02.pdfjs-dist
npm install pdfjs-dist@2.5.207问题一
注意 : 最好配置一下babel，因为打包的时候可能会报错
因为babel默认不会转化node_modules中的包，但是pdfjs-dist用了es6的东东
// 安装包
npm install babel-loader @babel/core @babel/preset-env -D在webpack.config.js中配置
{
test: /.js$/,
loader: 'babel-loader',
include: [
resolve('src'),
// 转化pdfjs-dist，之所以分开写，是因为pdfjs-dist里面有很多es6的语法，但是我们只需要转化pdfjs-dist里面的web文件夹下的js文件
resolve('node_modules/pdfjs-dist/web/pdf_viewer.js'),
resolve('node_modules/pdfjs-dist/build/pdf.js'),
resolve('node_modules/pdfjs-dist/build/pdf.worker.js'),
resolve('node_modules/pdfjs-dist/build/pdf.worker.entry.js') ]
},问题二
pdf.js文件过大，可以给 .babelrc 加上属性，“compact”: false
3.vuedraggable
npm install vuedraggable@2.24.3三、代码
1. 准备pdf文件
text.pdf 可放置在 src/static 文件夹中
ps : 线上最好让后端返回pdf链接，因为存在pdf跨域问题
2. 大佬的代码
