Redirecting a Node.js/Express request to another server-CodePudding

I got a situation where I need to redirect an HTTP request made to server X to another server Y,

with all of the requests' headers, params, body etc.

I tried:

app.post('/redirect-source', (req, res, next) => {
  res.redirect(301, 'http://localhost:4000/redirect-target');
});

But the response I get when reaching this route is:

{"message":"Not Found"}

Although the server and route i'm redirecting to are live and I get an ok response when reaching it directly.

What am I missing?

edit: I noticed that the target route works on Postman and not from the browser, my guess is because it's a POST request. How can I configure the redirect to pass as POST/specific type?

CodePudding user response：

Try to change the statusCode to 308.

Take a look at this https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/301

Use the 301 code only as a response for GET or HEAD methods and use the 308 Permanent Redirect for POST methods instead, as the method change is explicitly prohibited with this status.

CodePudding user response：

It turned out that status code 307 is the one that works for POST requests too. Like so:

app.post('/redirect-source', (req, res, next) => {
  res.redirect(307, 'http://localhost:4000/redirect-target');
});
