content-type：application/PDF更改为content-type：application/octet-stream

Question

const getData = async (req: Request, res: Response): Promise<void> => {
  try {
    .... some code...
    const response = await createPdfResponse(location);
    res.setHeader("Accept", "application/pdf");
    res.setHeader("Content-Type", "application/pdf");
    res.setHeader(
      "Content-Disposition",
      "inline; filename=fileName.pdf"
    );

    res.send(200, response);
  } catch (error) {
    const errorBody = error.body;
    const statusCode = error.code;
    res.send(statusCode, { errorBody });
  }
};

Answer 1

我找到解决办法了。这是由resitify代码引起的：

https://github.com/restify/node-restify/blob/master/lib/response.js#L477

只需使用res.sendraw(200,response）
