Я создаю приложение, которое получает от клиента JSON, содержащее данные на русском языке, но когда я пытаюсь его распечатать, используйте данные или верните их на клиентскую сторону. Я получаю кучу «?? ???»Неверная кодировка Java и String
Это на стороне клиента:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script src="js/angular.min.js"></script>
<script type="text/javascript">
function Ctrl($scope,$http) {
$scope.submit = function() {
//alert($scope.first+" "+$scope.last+" "+$scope.email+$scope.phone+$scope.subject+$scope.message);
$http({
method : 'GET',
url : '/healtcare',
headers: {'Content-Type': 'application/json; charset=UTF-8'},
params: {items:$scope.a}
/* params : {
first : $scope.first,
last : $scope.last,
email : $scope.email,
phone : $scope.phone,
subject : $scope.subject,
message : $scope.message
} */
}).success(function(data, status, headers, config) {
alert(data);
});
};
}
</script>
Это на стороне сервера:

То, что я посылаю:
{"first":"ИВАН","last":"ВГОВНО","email":"[email protected]","phone":"3245324324","subject":"ТЕМА","message":"ВСЯКАЯ ФИГНЯ И ДРУГОЙ ТЕКСТ"}
Это то, что я получаю (система из)
{"first":"????","last":"??????","email":"[email protected]","phone":"3245324324","subject":"????","message":"?????? ????? ? ?????? ?????"}
Я попытался создать новую строку с кодировкой UTF8, но это не сработало. Пожалуйста, помогите,
С уважением, идо
Nice фамилия. Ну, по крайней мере, хорошо, что это проявляется в вопросительных знаках ... :)) –
