常用下载函数

链接下载

export function downLoadFile(url: string, filename: string, blank = true) {
  if (!isURL(url)) return
  let downloadLink = document.createElement('a')
  downloadLink.download = filename
  downloadLink.href = url
  blank && (downloadLink.target = '_blank')
  downloadLink.click()
  window.URL.revokeObjectURL(downloadLink.href)
}

blob 下载

需要设置 responseType: 'blob'

axios 案例

export const postDownloadLetter = () =>
  axios.request({
    method: 'post',
    url: 'url',
    responseType: 'blob',
  })

代码

export const downloadBlob = (blob: any, fileName: string) => {
  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)
  document.body.removeChild(elink)
}
