vue导出pdf（接口）

get请求

export function getPdf(id) {
  const InfoRequestDTO = {
        consumer: store.getters.QLMConfig.application_id,
        language: store.getters.language,
        serialNo: uuid.v1(),
        tag: id
      };
  return request({
    url: store.getters.QLMConfig.qlm_gateway_url + "/specialwork/ZxjlGxcx/getPdf",
    method: 'get',
    params:InfoRequestDTO,
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded'
    },
    responseType: 'arraybuffer'
  })
}

调用：

daochu(id) {
      this.loading = true;
      getPdf(id).then(
        data => {
          this.loading = false;
          let blob = new Blob([data], { type: 'application/vnd.ms-pdf' })
          let objectUrl = window.URL.createObjectURL(blob) // 创建URL
          let link = document.createElement('a')
          link.style.display = 'none'
          link.href = objectUrl
          link.download = '突出贡献与创新申报表.pdf' // 自定义文件名
          document.body.appendChild(link)
          link.click() // 下载文件
          window.URL.revokeObjectURL(objectUrl) // 释放内存

          // const url = window.URL.createObjectURL(new Blob([data], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" }))
          // const link = document.createElement('a')
          // link.style.display = 'none'
          // link.href = url;
          // link.setAttribute('download', '突出贡献与创新申报表.pdf')
          // document.body.appendChild(link)
          // link.click()
          // document.body.removeChild(link)
        }
      )
    },

后端：

     * @param response
     * @return
     */
    @ApiOperation(value = "导出申报表", notes = "导出申报表")

        try {

            printFile("ndbg.ftl", root, fileName + ".doc", "C://specialworktempfile/", "C://specialworktempfile/");
            new PdfConverter().doc2pdf("C://" + fileName + ".doc", "C://" + fileName + ".pdf");
