你可以使用pdf.js库来在Vue中展示PDF文件流。首先,安装pdf.js库:
```
npm install pdfjs-dist
```
然后,创建一个Vue组件来展示PDF文件流:
```html
<template>
<div>
<canvas ref="canvas"></canvas>
</div>
</template>
<script>
import pdfjsLib from 'pdfjs-dist'
export default {
props: {
pdfData: {
type: Uint8Array,
required: true
}
},
mounted () {
this.renderPdf()
},
methods: {
renderPdf () {
const canvas = this.$refs.canvas
const pdfData = this.pdfData
pdfjsLib.getDocument({ data: pdfData }).promise.then(pdf => {
pdf.getPage(1).then(page => {
const viewport = page.getViewport({ scale: 1 })
const context = canvas.getContext('2d')
canvas.height = viewport.height
canvas.width = viewport.width
page.render({ canvasContext: context, viewport })
})
})
}
}
}
</script>
```
在这个组件中,我们使用pdf.js库来获取PDF文档,并在Canvas中渲染第一页。使用时,只需要传入PDF文件流作为`pdfData`属性即可:
```html
<template>
<div>
<PdfRenderer :pdfData="pdfData" />
</div>
</template>
<script>
import PdfRenderer from '@/components/PdfRenderer'
export default {
components: {
PdfRenderer
},
data () {
return {
pdfData: null
}
},
mounted () {
this.loadPdfData()
},
methods: {
loadPdfData () {
// 从服务器获取PDF文件流
// ...
this.pdfData = // PDF文件流
}
}
}
</script>
```
