vue本地环境proxy代理携带cookie问题

onProxyReq(proxyReq, req, res) {

        if (cookie) {

                proxyReq.setHeader('cookie', cookie )

        }

},

onProxyRes(proxyRes, req, res) {

        // 第一次login请求返回携带cookie，赋值保存，也仅仅login请求返回cookie

        var cookies = proxyRes.headers['set-cookie'];

        if (req.url.includes('login')&&cookies) {

                cookie = cookies;

        }

}
