Content-Type: application/pdf更改为Content-Type: application/octet-stream

Question

我有GET Http请求，如下所示

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 });
  }
};

当我收到响应时，它附带了Content-Type: application/octet-stream。

我需要Content-Type: application/pdf。

有没有人能帮我一下？我会非常感谢你的。

我找到了解决方案。这是由resitify代码引起的：

只需使用res.sendRaw(200, response)即可
