如何通过GraphQL将响应标头转发到客户端

Question

I'm having an issue using GraphQL where the response headers are being dropped when returning to client. My application is using NodeJS, Passport.js and Express Cookie-Session to manage authentication and sessions.

I have an existing /login route which authenticates with Passport and returns a user{} object and set-cookie headers to the client. In result, a cookie is created on the client's browser and their session is established.

Now, we have recently added GraphQL and I created a login query, which calls the existing /login route and responds with the user{} object. However, when the GraphQL returns the response to the client, the response headers are no longer included so the cookie is never created.

How can I forward the original response headers through GraphQL to reach the client?

Here is an example of the GraphQL login:

login { 
  type: typeLogin,
  args : { 'username/password here' },
  async resolve(_, args, context) {
    const response = await fetch('/login', {
      credentials: 'include',
      method: 'POST',
      body: JSON.stringify('username/password here')
   })

   const data = await response.json();

   // console.log(response.headers) will display correct headers

   return data; // User is returned but response headers are not
   }
 }

This is how I already do that,

Let me know if this works for you
