以下に定義されている単純な関数があります
function upload(response, postData) {
console.log("Received: " + postData);
response.writeHead(200,{"Content-Type":"text/plain"});
response.write("You've sent text: " + querystring.parse(postData).text);
response.end();
}
データをコンソールにログインすると正しく表示されますが、応答オブジェクトに書き込むと「未定義」と表示されます。なぜこれが起こるのですか?私のコードに間違いはありますか?
