在 node.js 中 res.json 之后的 res.redirect

Question

I have the following code below I want to redirect and return the response as well, can someone help me in this? What is the better solution for this?

try {
  res.json(await example.preview(access_token, context, id, body))
  res.redirect(`${sso.host}/session/login?grant_type=bearer&access_token=${access_token}&remember_me=true&redirect_uri=${encodeURIComponent(
 'https://example.com'
 )}`);
} catch (e) {
  logger.info(e);
  next(e);
}

Answer 1

You can't.

It isn't possible (and simply doesn't make sense) to simultaneously say both:

• Here is the thing you asked for
• The thing you asked for is not here, you need to request this URL instead

(This sounds like an XY Problem ; you might want to ask a new question about the problem you are trying to solve by asking how to do this impossible thing).

Answer 2

You can use res.json to return a regular 200 response, with any data you wish and also add a redirectURL item, which will be handled on the client side.

Example on client side:

// Simulate a mouse click:
window.location.href = redirectURL;

// Simulate an HTTP redirect:
window.location.replace(redirectURL);
