我应该如何关闭快递服务器?

I need to close server after getting callback from /auth/github/callback url. With usual HTTP API closing server is currently supporting with server.close([callback]) API function, but with node-express server i’m getting TypeError: Object function app(req, res){ app.handle(req, res); } has no method 'close' error. And I don't know how to find information to solve this problem.
How should I close express server?

NodeJS 配置注意事项:

NodeJS configuration notes:

$ node --version
v0.8.17
$ npm --version
1.2.0
$ npm view express version
3.0.6

实际应用代码:

var app = express();

// configure Express
app.configure(function() {
    // … configuration
});

app.get(
    '/auth/github/callback',
    passport.authenticate('github', { failureRedirect: '/login' }),
    function(req, res) {
        res.redirect('/');

        setTimeout(function () {
            app.close();
            // TypeError: Object function app(req, res){ app.handle(req, res); } has no method 'close'
        }, 3000)
    }
);

app.listen('http://localhost:5000/');

另外，我发现 'nodejs express close...' 但我不确定我是否可以将它与我拥有的代码一起使用:var app = express();.

Also, I have found ‘nodejs express close…’ but I don't sure if I can use it with code I have: var app = express();.

推荐答案

app.listen() 返回 http.Server.您应该在该实例上调用 close() 而不是在 app 实例上调用.

app.listen() returns http.Server. You should invoke close() on that instance and not on app instance.

例如

app.get(
    '/auth/github/callback',
    passport.authenticate('github', { failureRedirect: '/login' }),
    function(req, res) {
        res.redirect('/');

        setTimeout(function () {
            server.close();
            // ^^^^^^^^^^^
        }, 3000)
    }
);

var server = app.listen('http://localhost:5000/');

您可以检查源代码:/node_modules/express/lib/application.js
