Hi developers,
I want to send the the "id", "name", "score" to my server ( write the
records to server in a file named "ranking", path is http://
***.***.***.***/man/ranking,
I am sure the file exist, i have created it before, then i use the following
code to write, but it can't write into successful, Can anyone tell me why?
code:
private boolean updateRecord(String uid, String name, int score) {
HttpURLConnection conn = null;
try {
URL url = new URL("http://***.***.***.***/man/ranking";);
conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
DataOutputStream dos = new
DataOutputStream(conn.getOutputStream());
dos.writeUTF("UPDATE");
dos.writeUTF(uid);
dos.writeUTF(name);
dos.writeUTF(String.valueOf(score));
dos.flush();
dos.close();
DataInputStream dis = new
DataInputStream(conn.getInputStream());
String resultInfo = dis.readUTF();
if (resultInfo != null && !"ERROR".equals(resultInfo)) {
return true;
}
dis.close();
} catch (Exception e) {
Log.e("", "", e);
} finally {
if (conn != null)
conn.disconnect();
}
return false;
