问题描述
如何以简化的方式允许 CORS 使用多个域.
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 -
But if I want to have origin as an array of domains and I want to allow CORS for all the domains in the origin array, I would have something like this -
cors: {
origin: ["www.one.com","www.two.com","www.three.com"];
}
但问题是下面的代码不起作用 -
But then the problem is this below code would not work -
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();
});
如何让 res.header 通过 cors.origin 获取一个域数组?
How do I make res.header take an array of domains via cors.origin ?

我会推荐 cors-module: https://www.npmjs.org/package/cors它为您做这种事情 - 检查配置 CORS w/动态原点"-Section
