Express.js关闭响应

Question

Is there a way to close a response? I can use res.end() but it doesn't actually close the socket.

What I want to achieve: I am writing a Java program which interfaces with the network, and I am writing a node.js server for this. Java code:

String line;
while((line = in.readLine()) != null) {
    System.out.println("RES: "+line);
}

But this just keeps hanging.. No end connection, still waiting for input from the socket.

Node:

exports.getAll = function (req, res) {
    res.set("Content-Type", "text/plain");
    res.set(200);
    res.send(..data..);
    res.end();
}

however res.end() does not close the connection.. As said before, java keeps thinking there will be something next so it is stuck in the while loop.

Thank you

Answer 1

通过设置HTTP标头来关闭连接而不是默认保持活动策略来解决此问题。

res.set("Connection", "close");

Answer 2

如果真正想要关闭连接的人发现这一点，你可以使用res.socket或res.connection来获取destroy方法附带的net.Socket对象：

res.connection.destroy();
