后台方法的参数必须是@RequestBody修饰的。
前台关键代码:
axios ( {
method : 'post',
url : api.exportPlayTime , // 请求地址
data : {
choose : type,
begindate : startDate,
enddate : endDate
},
responseType : 'arraybuffer',
observe: 'response',
} )
.then ( ( res ) => {
const fileName = ""+filename+".xlsx"
let blob = new Blob([res.data], {type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"});
if ( 'download' in document.createElement ( 'a' ) ) { // 非IE下载
const elink = document.createElement ( 'a' )
elink.download = fileName
elink.style.display = 'none'
elink.href = URL.createObjectURL ( blob )
document.body.appendChild ( elink )
elink.click ()
URL.revokeObjectURL ( elink.href ) // 释放URL 对象
document.body.removeChild ( elink )
} else { // IE10+下载
navigator.msSaveBlob ( blob, fileName )
}
})
download(data) {
if (!data) {
return
}
let url = window.URL.createObjectURL(new Blob([data]))
let link = document.createElement('a')
link.style.display = 'none'
link.href = url
link.setAttribute('download', 'excel.xlsx')
document.body.appendChild(link)
link.click()
},
