我获取文件的函数：

  const getFile = async () => {
      console.log(currentDocNum);
      console.log(kpiShow.value);
      const responseFile = await rest.getFile(docsList[currentDocNum]);
      const downloadUrl = window.URL.createObjectURL(new Blob([responseFile.result]));
      const blob = new Blob([responseFile.result], { type: "application/pdf" });

      const temp = URL.createObjectURL(blob);
      const pdfSource = pdf.createLoadingTask(temp);
      console.log(temp);
      objectUrl.value = downloadUrl;
      
      pdfSource.promise.then((pdfTemp: any) => {
        numberPages.value = pdfTemp.numPages;
      });
      if (currentDocNum < docsNumber) currentDocNum++;
    };

const getFile = async (file: string): Promise<RestResponse<any>> => {
  return getRequest("/view/files?fileName="+file )
}

const getRequest = (requestString: string) =>
  viewAPI
    .get(requestString)
    .then((result) => ({ ok: true, result: result.data }))
    .catch((error) => Promise.resolve({ ok: false, error: error }))

和 div

  <div class="row" v-if="!kpiShow" >
    <pdf :src="objectUrl" :page="1" ></pdf>
</div>

Answer 1

应该是的

const getRequest = (requestString: string) =>
  viewAPI
    .get(requestString,{responseType:"blob"})
    .then((result) => ({ ok: true, result: result.data }))
    .catch((error) => Promise.resolve({ ok: false, error: error }))
