Извините, если мой английский плохой!Я использую модификацию 2 для получения данных, зависящих от данных POST.Я получаю данные с сервера, но у меня проблема с отправкой данных.Я пытался использовать разные аннотации (@Field, @Body с Object, @Body с данными HashMap), но каждая из них не работала.Вот мой код Java:

Вот мои журналы:
W/retroTest: sent --> DataResponse{numb=0, name='test row', value='null', status='null'}
W/retroTest: received --> DataResponse{numb=0, name='null', value='null', status='2'}
мой PHP-файл на сервере:
<?php
header("Content-type: application/json; charset=utf-8");
$inputJSON = file_get_contents('php://input');
$input = json_decode($inputJSON, TRUE);
$numb = $input['numb'];
$name = $input['name'];
if (isset($_POST['numb']) && !empty($_POST['numb'])) {
$numb = $_POST['numb']; }
if (isset($_POST['name']) && !empty($_POST['name'])) {
$name = $_POST['name']; }
if (!$numb) {
$json = json_encode( array(
"emp" => $name,
"status" => "2"));
} else {
$json = json_encode( array(
"emp" => "nothing",
"status" => "2"));
}
$myfile = fopen("testfile.txt", "w");
fwrite($myfile, $inputJSON);
fwrite($myfile, "\n");
fwrite($myfile, $numb);
fwrite($myfile, "\n");
fwrite($myfile, $name);
fclose($myfile);
echo $json;
?>
Файл testfile.txt также пуст, но когда я пытаюсь отправить POST почтальоном, все работает!
