在 Express 中获取 IP 地址和 GraphQL

Question

I have a question. So, I recently switched from rest to gql , and I have a problem. In rest I got ip address by req.ip . I tried to do it in resolve() function and it wasn't working (undefined) . I searched the web and found this:

const server = new GraphQLServer({
  context: context => ({
    ...context,
    db,
    userIp: maybeGetUserIpAddress(context.request),
  }),
});

const maybeGetuserIpAddress = (request): ?string => {
  const headers = request.headers;
  if (!headers) return null;
  const ipAddress = headers['x-forwarded-for'];
  if (!ipAddress) return null;
  return ipAddress;
};

But it returns undefined too.

So, my questions are:

1. Is this because I'm hosting my server locally?
2. What is wrong with the code

Answer 1

Yes it's because you are on localhost req.ip && req.socket.remoteAddress won't do the trick.

You can use this instead.

(req -> express.Request)

  const ip = require('ipware')().get_ip(req)?.clientIp || req?.ip || req?.socket?.remoteAddress || '127.0.0.1'
