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
}
