http-proxy-middleware, how to copy all/cookie headers

问题

I am using lite server by John Papa with HTTP proxy middleware by chimurai as a dev server. the problem is with my session cookie, I cannot persist the session cookie that comes from the real server. I saw this solution: https://github.com/chimurai/http-proxy-middleware/issues/78

but I see no resemblance to my bs-config.js:

var proxy = require('http-proxy-middleware');

module.exports = {
    port: 3003,
    server: {
        middleware: {
            1: proxy('demo/webservice/jaxrs', {
                target: 'https://localhost:8443',
                secure: false, // disable SSL verification
                changeOrigin: true   // for vhosted sites, changes host header to match to target's host
            }),
            2: require('connect-history-api-fallback')({index: '/index.html', verbose: true})
        }
    }
};

Does someone knows how to merge this two?

UPDATE: this is part of the response headers:

set-cookie:JSESSIONID=620083CD7AEB7A6CC5772AC800E673E3; Path=/appServer/webservice/jaxrs; Secure
strict-transport-security:max-age=31622400; includeSubDomains
Transfer-Encoding:chunked

UPDATE2: I think my config should look like this:

var proxy = require('http-proxy-middleware');

function relayRequestHeaders(proxyReq, req) {
    Object.keys(req.headers).forEach(function (key) {
        proxyReq.setHeader(key, req.headers[key]);
    });
};

function relayResponseHeaders(proxyRes, req, res) {
    Object.keys(proxyRes.headers).forEach(function (key) {
            res.append(key, proxyRes.headers[key]);
        });
};

module.exports = {
    port: 3003,
    server: {
        middleware: {
            1: proxy('/skybox', {
                target: 'https://localhost:8443',
                secure: false, // disable SSL verification
                changeOrigin: true,   // for vhosted sites, changes host header to match to target's host
                onProxyReq: relayRequestHeaders,
                onProxyRes: relayResponseHeaders
            }),
            2: require('connect-history-api-fallback')({index: '/index.html', verbose: true})
        }
    }
};

but now res.append is undefined :(

回答1:

try it:

var cookie;
function relayRequestHeaders(proxyReq, req) {
  if (cookie) {
    proxyReq.setHeader('cookie', cookie);
  }
};

function relayResponseHeaders(proxyRes, req, res) {
  var proxyCookie = proxyRes.headers["set-cookie"];
  if (proxyCookie) {
    cookie = proxyCookie;
  }
};

It's working with lite-server

回答2:

Not sure how your localhost:3003 is configured; With or without https:...

Say you are using http://localhost:3000 (not https:); The Secure cookie attribute from your target might be the cause for your browser to omit the cookie.

4.1.2.5. The Secure Attribute

The Secure attribute limits the scope of the cookie to "secure"
channels (where "secure" is defined by the user agent). When a
cookie has the Secure attribute, the user agent will include the
cookie in an HTTP request only if the request is transmitted over a
secure channel (typically HTTP over Transport Layer Security (TLS)

source: https://tools.ietf.org/html/rfc6265#section-4.1.2.5

Browsers may omit cookies based on the algorithm described in: https://tools.ietf.org/html/rfc6265#section-5.4

Try removing the Secure Attribute and see if that helps
