Javascript 如何使用axios从nodejs接收文件

我需要axios从nodejs获取pdf缓冲区和更多数据信息

如果我将axios post设置为responseType:“arraybuffer”，并使node只发送它正在工作的pdf缓冲区

但是我需要从节点返回更多的数据信息，如果我去掉“responseType:arrayBuffer”，为了接收json，我无法使用新的Blob函数将pdfBuffer转换为pdf。 我的血块无效

我做错了什么

这不起作用：

//前端：

const resp=await axios.post("atestadosClientes/generatePDF", data);

 const file = new Blob([response.data.pdfBuffer], {
          type: "application/pdf",
        });
//Build a URL from the file
const fileURL = URL.createObjectURL(file);

//Node response:generate pdf buffer
return res.send({
      message: "Success",
      id: resp[0].insertId,
      pdfBuffer: pdfSignedBuffer, //pdf buffer
    });

const resp=await axios.post("atestadosClientes/generatePDF", data, {
      responseType: "arraybuffer",
    });
  },
const file = new Blob([response.data], {
          type: "application/pdf",
        });
//Build a URL from the file
const fileURL = URL.createObjectURL(file);

这是有效的：

//前端：

const resp=await axios.post("atestadosClientes/generatePDF", data);

 const file = new Blob([response.data.pdfBuffer], {
          type: "application/pdf",
        });
//Build a URL from the file
const fileURL = URL.createObjectURL(file);

//Node response:generate pdf buffer
return res.send({
      message: "Success",
      id: resp[0].insertId,
      pdfBuffer: pdfSignedBuffer, //pdf buffer
    });

const resp=await axios.post("atestadosClientes/generatePDF", data, {
      responseType: "arraybuffer",
    });
  },
const file = new Blob([response.data], {
          type: "application/pdf",
        });
//Build a URL from the file
const fileURL = URL.createObjectURL(file);

//节点响应：生成pdf缓冲区

return res.send(pdfBuffer)
