Ethernet & Wi-Fi Module

Arduino WebServer

การใชงาน Http Connection ( Android )

HttpURLConnection conn = null;

try {

conn = (HttpURLConnection)new URL("http://someurl").openConnection();

conn.setRequestMethod("GET");

conn.setInstanceFollowRedirects(true);

conn.setUseCaches(false);

int resCode = conn.getResponseCode();

if (resCode == HttpURLConnection.HTTP_OK) {

InputStream is = conn.getInputStream();

ByteArrayOutputStream bos =

new ByteArrayOutputStream();

int read = 0;

while ((read = is.read()) != -1) {

bos.write(read);

}

byte[] result = bos.toByteArray();

bos.close();

}

( code ตอหนา 2 )

else {

// do something

}

conn.disconnect();

}

catch (Exception e) {

// do something

}
