post实现下载/导出功能

话不多说 直接上码

downLoad (row) {
      let params = new FormData()
      params.append('xxx', '1')
      params.append('yyy', '2')
      const data = await this.$http.post('', params, {responseType: 'blob'})
      let blob = new Blob([data.data], { type: 'application/zip' })
      if (window.navigator.msSaveOrOpenBlob) {
      	// 兼容ie
        navigator.msSaveBlob(blob)
        // navigator.msSaveBlob(blob,'xxx.xx') //可自定义文件名
      } else {
        let objectUrl = URL.createObjectURL(blob)
        let downLoadLink = document.createElement('a')
        downLoadLink.href = objectUrl
        // downLoadLink.download = '' // 可自定义文件名
        document.body.appendChild(downLoadLink)
        downLoadLink.click()
        document.body.removeChild(downLoadLink)
        window.URL.revokeObjectURL(downLoadLink.href)
      }
    }
