GET 요청 보내기

URL url = new URL(path);
// 
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
// 
conn.setRequestMethod("GET");
conn.setConnectTimeout(5000);
conn.setReadTimeout(5000);
// ， 
if(conn.getResponseCode() == 200){

}

서버에서 되돌아오는 흐름을 가져오고 흐름에서 html 원본을 읽습니다

byte[] b = new byte[1024];
int len = 0;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
while((len = is.read(b)) != -1){
    // 
    bos.write(b, 0, len);
}
// 
// utf-8
text = new String(bos.toByteArray());

무분별한 처리

// 
text = new String(bos.toByteArray(), "utf-8");
