摘要：
exportfunctiondownloadFile（obj，name，后缀=“xlsx”）｛consturl=window.URL.createObjectURL（newBlob（[obj]，｛type:“application/vnd.ms-excel”｝））constlink=document.createElement（'a'）link.style.display='none'li
export function downloadFile(obj, name, suffix = "xlsx") {
const url = window.URL.createObjectURL(new Blob([obj], {type: "application/vnd.ms-excel"}))
const link = document.createElement('a')
link.style.display = 'none'
link.href = url
const fileName = name + '-' + parseTime(new Date()) + '.' + suffix
link.setAttribute('download', fileName)
document.body.appendChild(link)
link.click()
document.body.removeChild(link)
}
按照以上方式导出出现文件损坏提示, 原因是请求时少了请求头responseType: ‘blob’
加上请求头即可
