问题描述

是否可以使用Node.js和express放弃对某些路由的请求? IE.不返回http状态或任何标题?我只想关闭连接.

Is it possible using Node.js and express to drop a request for certain route? I.E. not return a http status or any headers? I'd like to just close the connection.

app.get('/drop', function(req, res) {
    //how to drop the request here
});

推荐答案

要关闭连接而不返回任何内容，您可以

To close a connection without returning anything, you can either end() or destroy() the underlying socket.

app.get('/drop', function(req, res) {
  req.socket.end();
});    

我认为没有任何办法可以在您端断开连接，但是要让客户端等待直到超时(即不发送FIN).您可能必须以某种方式与防火墙进行交互.

I don't think there's any way to drop the connection at your end but keep the client waiting until it times out (i.e. without sending a FIN). You'd perhaps have to interact with your firewall in some way.
