Node.js和express ReferenceError:未定义响应

Question

这是我的代码

var express = require('express');
var fs = require('fs');
var config = JSON.parse(fs.readFileSync("./config.json"));
console.log(config);
var host = config.host;
var port = config.port;

var app = express.createServer();

// use route
app.use(app.router);

// for static files this location
app.use(express.static(__dirname));

// root path
app.get('/', function (request, response) {

    response.send("hello");
});


app.get("/id/:id", function (request, reponse) {


    var value = request.params.id;
    console.log(value);
    response.send(value.toString());

});

app.listen(port, host);

我可以在url 127.0.0.1:3317/id/ hello中记录id之后的值

Hello在控制台中打印但是有一个ReferenceError:响应未定义 错误.

请帮帮我
