1、下载表格（二进制）

exportExcel () {
    axios.get(url, {
            headers:{
                "Admin_token":token
            },
            responseType: 'blob', //二进制流
        }).then(function (res) { // res为后端接口返回二进制流数据
            if(!res) return
            const content = res
            const blob = new Blob([content], {type: 'application/vnd.ms-excel'})
            const fileName = '下载表格'+ '.xls'
            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)
            }
        }).catch(function (error) {
            console.log(error)
        })
    }
