Sau đó, trong mã của bạn:
public void yourmethod(String url, String type, String reqbody){
HttpURLConnection con = null;
String result = null;
try {
con = conUtil.getHttpConnection( url , type);
//you can add any request body here if you want to post
if( reqbody != null){
con.setDoInput(true);
con.setDoOutput(true);
DataOutputStream out = new DataOutputStream(con.getOutputStream());
out.writeBytes(reqbody);
out.flush();
out.close();
}
con.connect();
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
String temp = null;
StringBuilder sb = new StringBuilder();
while((temp = in.readLine()) != null){
sb.append(temp).append(" ");
}
result = sb.toString();
in.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
logger.error(e.getMessage());
}
//result is the response you get from the remote side
