我想实现读取一个本地的xlsx文件(task_list.xlsx)然后显示在网页上, 一开始选择的方法是建个express server, 通过发送axios请求来实现, 但是觉得只是读取一个本地文件还要搞个server太复杂了, 最终还是通过"xlsx"模块 + axios实现了读取本地文件, 无需后端, 步骤如下:
1.通过vue-cli新建项目:

2.编写分析excel workbook的脚本
/src/scripts/read_xlsx.js
const XLSX = require('xlsx')
//将行,列转换
function transformSheets(sheets) {
var content = []
var content1 = []
var tmplist = []
for (let key in sheets){
//读出来的workbook数据很难读,转换为json格式,参考https://github.com/SheetJS/js-xlsx#utility-functions
tmplist.push(XLSX.utils.sheet_to_json(sheets[key]).length)
content1.push(XLSX.utils.sheet_to_json(sheets[key]))
}
var maxLength = Math.max.apply(Math, tmplist)
//进行行列转换
for (let y in [...Array(maxLength)]){
content.push([])
for (let x in [...Array(tmplist.length)]) {
try {
for (let z in content1[x][y]){
content[y].push(content1[x][y][z])
}
} catch (error) {
content[y].push(' ')
}
}
}
content.unshift([])
for (let key in sheets){
content[0].push(key)
}
return content
}
export {transformSheets as default}3.新建一个组件
/src/components/task_list.vue
