为什么 post 请求不发送 cookies？

Question

I am trying to send an HTTPonly cookie containing my refresh token to my server. The cookie is shown below

res.cookie('refreshtoken', token, {
    httpOnly: true,
    sameSite: 'strict',
    path: '/refresh_token',
    expires: new Date(Date.now() + 7 * 216000000)   //    Token expires in 7 days
  });

I am making a post request to a server that is running on the same port/domain so it shouldn't need cors. When I take a look at the sent request, there are no cookies sent. I'm running my server on localhost which may be causing the issue, but I'm not sure.

Regardless if I use same-origin or include for the credentials, no cookie is sent.

const result = await (
          await fetch('http://localhost:5000/api/refresh_token', {
            method: 'POST',
            credentials: 'same-origin',
            headers: {
              'Content-Type': 'application/json',
            }
          })).json();

For anyone reading this in the future, path refers to the absolute path. So 'api/refresh_token' won't match with '/refresh_token'. This allowed my cookie to be sent.
