Hello. The task is to write a client on android to work with this section of the site http://91.200.160.20/search.php . However, I can not log in to it. The jsoup library is used. So, for the formation of a post request we have

<form action="alogon.php" id="loginform" method="POST"> <table border="0" cellpadding="0" cellspacing="0"> <tr> <td width="158"> <table width="100%" border="0" cellpadding="0" cellspacing="0"> <tr> <td> <div> <label for="loginEnterToSite" class="labelLogin">№ читательского билета</label> <input name="id" value="" id="loginEnterToSite" type="text" style="width:143px;height:15px;"> </div> </td> </tr> <tr> <td> <div> <label for="passwordEnterToSite" class="labelPass">ПИН - код</label> <input name="user_pass" id="passwordEnterToSite" value="" type="password" style="width:63px;height:15px"> </div> </td> </tr> </table> </td> <td width="41"> <input type="image" name="submit" src="menu/loginimage/sup5.gif" style="border-style:none"> </td> </tr> <tr> <td colspan=2> <input type=checkbox name=remember>Запомнить &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a class='all_1' href="javascript:void(0);" onmouseover="Tip('<font color=#FF0000><b>Паролем является PIN код.</b></font><br><br>При утрате PIN кода необходимо обратиться в отдел &laquo;Учета и регистрации&raquo;.<br><br>Если у Вас нет PIN кода, то в качестве пароля можно использовать<br>первые буквы фамилии имени и отчества.<br><br>Например, читатель Iванов Євген Іванович,<br>читательский № 1234567 вводит номер Ч.Б. -<b><font color=#FF0000>1234567</font></b>, пароль - <b><font color=#FF0000>ІЄІ</font></b>', SHADOW, true, SHADOWWIDTH, 4, SHADOWCOLOR, '#007FFF')" onmouseout="UnTip()">Напомнить&nbsp;пароль</a> </td> </tr> </table> </form>

In the fields with "http" links, changed to "ttp" due to lack of reputation.

The code that is used to authorize and receive cookies:

 Connection.Response loginGet = Jsoup.connect("http://91.200.160.20/search.php") .method(Connection.Method.GET) .execute(); Connection.Response loginPost = Jsoup.connect("http://91.200.160.20/alogon.php") .data("id",mLog) .data("user_pass",mPassword) .data("submit.x", "27") .data("submit.y", "13") .data("remember", "on") .cookies(loginGet.cookies()) .userAgent("Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.110 YaBrowser/16.4.1.8949 Safari/537.36") .referrer("http://91.200.160.20/search.php") .method(Connection.Method.POST) .execute(); Log.d("ex","loginPost" + loginPost.cookies()); Log.d("ex","loginGet" + loginGet.cookies());

When outputting cookies to the logs, this is what I get:

  D/ex: loginPost{login=deleted, pass=deleted} D/ex: loginGet{PHPSESSID=t21o83o1336qk5ea4mhf2var27, pc_id=2185}

I can not understand, because of what writes login = deleted and pass = deleted. Could this be due to the fact that the password is a combination of characters in Cyrillic? If so, would you tell me how to get around this? And if not, then what could cause such a problem and what am I doing wrong?
