----------------------- GET ----------------------------
String getUrl = "https://github.com/Hyman1993";
URL url = new URL(getUrl);
//connectionのインスタンス
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
//リクエストのメソッドを指定
connection.setRequestMethod("GET");
//通信開始
connection.connect();
// レスポンスコードを戻る
int responseCode = connection.getResponseCode();
// レスポンスコードを判断する、OKであれば、進める
if(responseCode == HttpURLConnection.HTTP_OK){
// 通信に成功した
// テキストを取得する

}
// クローズ

---------------------------- POST -----------------------------
String postUrl = "https://github.com/Hyman1993";

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
//POSTに指定
connection.setRequestMethod("POST");
//POST出力可能

//入力可能
connection.setDoInput(true);
//cache無し
connection.setUseCaches(false);
// データタイプをjsonに指定する
connection.setRequestProperty("Content-Type", "application/json;charset=utf-8");
//コネクション、通信開始
connection.connect();
// jsonデータを出力ストリームへ書き出す
String body = "userName=hyman1993&password=123456";
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(connection.getOutputStream(), "UTF-8"));
writer.write(body);
writer.close();
int responseCode = connection.getResponseCode();
if(responseCode == HttpURLConnection.HTTP_OK){
// 通信に成功した
// GETメソッドを同様に
}
