vue中通过blob流下载excel模板(接口支撑)

<Button @click="getLoadTemplate" type="primary">下载模板</Button>

export const getTemplate = () => {
  return axios.request({
    url: "...",
    method: "get",
    responseType: "blob"    //**********************************
  });
};

getTemplate () {
      getTemplate().then(res => {
        // res.data 是一个file流文件 
        const blob = new Blob([res.data], { type: 'application/vnd.ms-excel' })
        //const blob = new Blob([res.data],{type:'application/octet-stream'})
        //const blob = new Blob([res.data], "application/vnd.ms-excel;charset=utf-8")
        const downloadElement = document.createElement('a')
        const href = window.URL.createObjectURL(blob)
        downloadElement.href = href
        downloadElement.download = '模板.xls'
        document.body.appendChild(downloadElement)
        downloadElement.click()
        document.body.removeChild(downloadElement)
        window.URL.revokeObjectURL(href)
      }).catch(err => {
        console.log(err)
      })
    },
