1、使用npm 下载vue-pdf
npm install --save vue-pdf
2、封装pdf组件
<template>
<div style="height: 75vh;overflow-y: auto;overflow-x: hidden;">
<pdf :src="src"></pdf>
</div>
</templete>
import pdf from 'vue-pdf'
export default {
components: {pdf},
data(){
return{
src: '',
}
},
methods: {
//预览pdf
previewPDF(url){
this.src = pdf.createLoadingTask(url)
},
//下载PDF
downloadPDF(url,fileName){
this.axios({
method: 'get',
responseType: 'arraybuffer',
url: url
}).then(function(res){
//调用下载方法，把后端传过来的流传给fileDownload方法
this.fileDownload(res.data, fileName);
}.bind(this)
)
.catch(
function(error) {
this.$Message.error("网络请求出错")
//调试阶段可以看看报的什么错
//console.log("error",error)
}.bind(this)
);
},
fileDownload:function (data, fileName) {
let blob = new Blob([data], {
//type类型后端返回来的数据中会有，根据自己实际进行修改
type: "application/vnd.ms-excel"
});
let filename = fileName || "报表.xls";
if (typeof window.navigator.msSaveBlob !== "undefined") {
window.navigator.msSaveBlob(blob, filename);
} else {
var blobURL = window.URL.createObjectURL(blob);
// 创建隐藏<a>标签进行下载
var tempLink = document.createElement("a");
tempLink.style.display = "none";
tempLink.href = blobURL;
tempLink.setAttribute("download", filename);
if (typeof tempLink.download === "undefined") {
tempLink.setAttribute("target", "_blank");
}
document.body.appendChild(tempLink);
tempLink.click();
document.body.removeChild(tempLink);
window.URL.revokeObjectURL(blobURL);
}
}
}
}
3、在组件中具体使用封装的pdf组件
<templete>
<div>
<PDF ref="pdf"></PDF>
<Button type="primary" size="small" @click="previewWeekly(item.id)">预览</Button>
<Button type="primary" size="small" @click="downloadWeekly(item.id,item.name)">下载</Button>
</div>
</templete>
<script>
import PDF from '../../../../../components/UM/MAM/pdfPerviewDownload'
import Vue from 'vue';
export default {
components: {PDF},
methods:{
//预览
previewWeekly(id){
//调用子组件的预览方法
//完整的地址应该是发布到服务器的地址，不应该是localhost:8080这样的
//Vue.prototype.ApiUrl 用来读取服务器地址 比如:
//http://192.168.8.152:8080/MixShowView-Web/reports/preview/1
this.$refs.pdf.previewPDF(Vue.prototype.ApiUrl+'/reports/preview/'+id)
},
//下载
downloadWeekly(id,fileName){
//调用子组件的下载方法
this.$refs.pdf.downloadPDF(Vue.prototype.ApiUrl+'/reports/download/'+id,fileName)
}
}
};
</script>
4、打包的时候会报错
if (Object({"NODE_ENV":"production","API_ROOT":http://192.168.6.112:8080/MaxTunnel-Web}).VUE_ENV !== 'server') {
var pdfjsWrapper = __webpack_require__("ytml").default;
Build failed with errors.
解决方案是在build/webpack.prod.conf.js中加上
new webpack.DefinePlugin({
'process.env': env,
'process.env.VUE_ENV': JSON.stringify(process.env.VUE_ENV) //增加此行,将src地址转换成json字符串。
}),
