axios設置返回格式爲arraybuffer 或者 blob(最佳 不會亂碼)ios
例如:json
this.$axios({axios
method: 'post',服務器
header: {'Content-Type': 'application/xls'}, // http請求類型app
responseType: 'blob', // 返回格式,默認json,可選arraybuffer、blob、document、json、text、streampost
url: url,this
data: dataurl
})orm
.then( res =>{xml
//application/vnd.openxmlformats-officedocument.spreadsheetml.sheet這裏表示xlsx類型
let blob = new Blob([res.data], {type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8'});
let downloadElement = document.createElement('a');
let href = window.URL.createObjectURL(blob);
downloadElement.href = href;
downloadElement.download = '反饋消息表.xls'; // xxx.xls/xxx.xlsx
document.body.appendChild(downloadElement);
downloadElement.click();
document.body.removeChild(downloadElement);
window.URL.revokeObjectURL(href);
})
