<el-button type="primary" plain  @click="allDownload">下载</el-button>

methods:{allDownload(){const params =this.exportAllParams
      console.log(params)// const params = JSON.parse(JSON.stringify(this.searchParams))delete params.current
      delete params.size
      delete params.total
      allExportList(params).then((res)=>{const blob =newBlob([res],{type:'application/vnd.ms-excel'})const a = document.createElement('a')const href = window.URL.createObjectURL(blob)
        a.href = href
        a.download ='实时监控'
        document.body.appendChild(a)
        a.click()// console.log(a)
        document.body.removeChild(a)
        window.URL.revokeObjectURL(href)})},}
