this.$http({

    method:‘post’,

    url:’’,

    data:{},

    responseType:’arraybuffer’

})

.then((res) => {

    const fileName =‘order’;

    const blob = newBlob([data],{ type: 'application/vnd.ms-excel' });

    const link =document.createElement('a');

    link.href =window.URL.createObjectURL(blob);

    link.download = fileName+’.xls’;
