在 express js 中允许多个 CORS 域

How do I allow multiple domains for CORS in express in a simplified way.

我有

 cors: {
        origin: "www.one.com";
    }

    app.all('*', function(req, res, next) {
            res.header("Access-Control-Allow-Origin", cors.origin);
            res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
            next();
        });

这在 origin

但是，如果我想将 origin 作为域数组，并且我想允许原始数组中的所有域使用 CORS，我就会有这样的东西 -

cors: {
            origin: ["www.one.com","www.two.com","www.three.com"];
        }

app.all('*', function(req, res, next) {
                res.header("Access-Control-Allow-Origin", cors.origin);
                res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
                next();
            });
