Access_token在本地主机中工作，不在服务器中

Question

I am using the following code in my application to check if some headers are provided .The code works fine in localhost but not when the application is deployed to server . Basically I am trying to check if headers are present in the request. On the server , I keep getting invalid request . When I pass accesstoken instead of access_token , the request goes through successfully . So by changing if ((request.headers.access_token && request.headers.refresh_token && request.headers.id_token) || request.headers.token) to

The code works , my question is why is this happening

const Hapi = require('hapi');
const Path = require('path');
const axios = require('axios');

    var tokenValidation = function (request, reply) {


            if ((request.headers.access_token && request.headers.refresh_token && request.headers.id_token) || request.headers.token) {

                if (request.headers.access_token != undefined) {
                   //do something
                    }
                    else {
                        return reply.continue();
                    }

                } else
                    return reply.continue();
            } 
            else {
                var err = Boom.badRequest(‘Invalid request.');
                reply(err);
            }
        }

        server.ext('onRequest', tokenValidation);

Missing (disappearing) HTTP Headers If you do not explicitly set underscores_in_headers on;, NGINX will silently drop HTTP headers with underscores (which are perfectly valid according to the HTTP standard). This is done in order to prevent ambiguities when mapping headers to CGI variables as both dashes and underscores are mapped to underscores during that process.

We have to explicitly underscores_in_headers on in NGINX , else they will be ignored
