thanks ulrich

when seek utilize code simulate action done in browser , 1 of best api in java world httpclient, give many features create code deed user in front end of browser (fill input, click, load link ...) . here tutorial start.

but in case want utilize stardard java api without 3rd party library, there here few lines hope helpful :

first seek specify in url domaine name , page want invoke when requesting server ex:

url url = new url("http://www.mydomaine.com/test.php");

if website show popup authentication login/pass when trying access seek url instead :

url url = new url("http://login:password@www.mydomaine.com/test.php");

if show login form , seek access sending login , pass if fill input then, first thing identify name of input used when send request server , may login , password or else, find name seek inspect page browser (view source code of page or seek inspecting html elements) find :

<form action="login.php" method="post"> <input type="text" name="my_login"> <input type="password" name="my_password"> </form>

let's suppose names my_login , my_password , in case the page have invoke login.php (which value of action form) code :

url obj = new url("http://www.mudomaine.com/login.php); httpurlconnection con = (httpurlconnection) obj.openconnection(); con.setrequestmethod("post"); string datas = "my_login=administrator&my_password=s3cred0n3"; con.setdooutput(true); dataoutputstream wr = new dataoutputstream(con.getoutputstream()); wr.writebytes(datas); wr.flush(); wr.close();

you can handle result calling con.getinputstream() if want manage server result .

but repeat 1 time again , if can utilize 3rd library utilize , because simplify job , , cut down possible bug in code.
