How to set the location response HTTP header in Express framework?
提问by gremo
How to set the response LocationHTTP header in Express? I've tried this, but it's not working:
如何Location在 Express 中设置响应HTTP 标头？我试过这个，但它不起作用：
Controller.prototype.create = function(prop, res) {
var inst = new this.model(prop);
inst.save(function(err) {
if (err) {
res.send(500, err);
}
res.location = '/customers/' + inst._id;
res.send(201, null);
});
};
This code is persisting a new document into MongoDB, and upon competition sets the location and send a 201response. Got this response, no Locationheader is set:
这段代码将一个新文档持久化到 MongoDB 中，并在竞争时设置位置并发送201响应。得到这个响应，没有Location设置标题：
HTTP/1.1 201 Created
X-Powered-By: Express
Content-Length: 0

EDIT: as u?op ?p?sdn(cool nick btw) answer, res.setHeaderworks. But why res.locationdoesn't?
编辑：作为u?op ?p?sdn(cool nick btw) 回答，res.setHeader有效。但为什么res.location不呢？

you're setting res.location. res.locationis a function.
你正在设置res.location。res.location是一个函数。
res.location('/customers/' + inst._id)

The resobject exposes setHeader():
该res对象公开setHeader()：
res.setHeader('Location', foo);
Try that instead of res.location.
试试那个而不是res.location.
