Question

我的前端运行在react + flux + node和后端运行在Java中。我正在使用superagent将响应操作的请求发送到成功发生的后端，我正在尝试从后端发送自定义标头，这也正常工作并从后端发送到前端，我可以在浏览器网络中看到（调试请求和响应）。但是当我尝试访问反应动作中的标题时，我没有看到它。有人请指导我如何处理这个？

我想要访问的自定义标头是X-Token但是我无法在反应动作的superagent的响应中看到它。反应动作功能如下所示：

login(payload) {
        request.post(someurl+'/login')
            .send({
                username: payload.userEmail,
                password: payload.userPassword
                })
            .set('Accept', 'application/json')
            .end(function(err, res){
                if (err || !res.ok) {

                } else {
                    console.log(res.headers) //it doesnt give x-token header.

                }
            });
    }
}

以下是我的服务器js内容：

var app = express();
app.options('*', cors());

app.set('port', process.env.PORT || 3001);
app.use(compression());
app.use(logger('dev'));
app.use(bodyParser.urlencoded({
    extended: true
}));
app.use(bodyParser.json());

app.use(function (req, res, next) {
         // Website you wish to allow to connect
         res.setHeader('Access-Control-Allow-Origin', '*');

         // Request methods you wish to allow
         res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');

         // Request headers you wish to allow
         res.setHeader("Access-Control-Allow-Headers", "X-Token,Origin,X-Requested-With,content-type");

         // Set to true if you need the website to include cookies in the requests sent
         // to the API (e.g. in case you use sessions)
         res.setHeader('Access-Control-Allow-Credentials', true);

         // Pass to next layer of middleware
         next();
     });


app.use(express.static(path.join(__dirname, 'public')));

app.engine('html', consolidate['swig']);
app.set('view engine', 'html');
app.set('views', './views');


 app.use(function(req, res) {
   Router.match({ routes: routes.default, location: req.url }, function(err, redirectLocation, renderProps) {
     if (err) {
       res.status(500).send(err.message)
     } else if (redirectLocation) {
       res.status(302).redirect(redirectLocation.pathname + redirectLocation.search)
     } else if (renderProps) {
       var html = ReactDOM.renderToString(React.createElement(Router.RoutingContext, renderProps));
       var page = swig.renderFile('views/index.html', { html: html });
       res.status(200).send(page);
     } else {
       res.status(404).send('Page Not Found')
     }
   });
 });

require('./app/routes/server-route')(app, express);
var server = require('http').createServer(app);


server.listen(app.get('port'), function() {
   console.log('Express server listening on port ' + app.get('port'));
});

提前感谢您的帮助。

您确定setHeader吗？

标题的

express documentation api为setHeaders。
