こんにちは、コールバックメソッドを使用してhttp経由で応答を取得しようとしています。しかし、私は多くの情報を得ることではなく、私のデータ：ノードJSのノードJSのHTTP要求コールバック

マイノードJSコードは次のとおりです。
var http = require('http');
function getRoutes(callback){
\t var callback = request('http://localhost/php-rest/api.php/routes?filter=route_short_name', function(error, response, body, callback) {
\t \t if (!error && response.statusCode == 200) {
\t \t \t result = JSON.stringify(JSON.parse(body));
\t \t \t //console.log(result);
\t \t \t //res.setHeader('Content-Type', 'application/json');
\t \t \t //res.send(result);
\t \t \t return callback = result;
\t \t } else {
\t \t \t //res.end('Error: ' + error);
\t \t \t return callback = error;
\t \t }
\t });
\t return callback;
}
app.get('/getRoutes', function(req, res) {
\t var data = getRoutes();
\t console.log(data);
\t //res.setHeader('Content-Type', 'application/json');
\t res.send(data);
});私は、コールバック（結果やエラーの内容を）したいです。 誰かが私にこれを手伝ってもらえると大変感謝します。
その仕事：私はコールバックについてもっと学びます。ありがとう^^ –
