I'm trying to redirect a user request to another url on post with some additional data.
Lets say the user does POST /profile/update
Afterwards, I want to redirect the user to another url with some additional data.
e.g., POST /test body with a body, {"foo": "bar"}
How can I do this?
app.post('/profile/update', function(req, res) { res.redirect(307, '/test') // but dont know how to pass some body here: {"foo":"bar"} }); From what I understand you are doing it in the right way. Your data should be passed directly to the route /test. i.e., if you do req.body in the code of the route /test after having redirected, you should see the data that came from /profile/update. Take a look at this answer and the docs.
If it is confusing and you do not want to redirect, I suggest you do something different. Create a controller for the route /test (i.e., move the code inside the route do a different script called testController.js and inside the route invoke it). Then just go with:
app.post('/profile/update', function(req, res) { testController.test(req.body); });
