AngularJS HTTP POST不發送數據

Question

我必須使用Angular JS通過HTTP POST發送一個簡單的JSON對象。

我有一個簡單的ng-clik鏈接函數：

$scope.requestGoogleAuth = function() {
        var googleCredentials = {
            email: 'user@domain.com',
            password: 'a2s4d'
        };
        console.log(JSON.stringify(googleCredentials));
        /*$http({
            url: '/MyServlet',
            method: "POST",
            data: JSON.stringify(googleCredentials),
            headers: {'Content-Type': 'application/json'}
        })*/
        $http.post("/MyServlet", JSON.stringify(googleCredentials)).then(function success(response) {
            $('#loginGoogleModal').modal('hide');
            $("#notificationsWrapper").notify(
                "Logged with Google",
                {
                    className: 'success',
                    position: 'bottom right'
                }
            );
            $scope.googleLogged = true;
            console.log($scope.googleLogged);
        }, function error(response) {
            $('#loginGoogleModal').modal('hide');
            $("#notificationsWrapper").notify(
                "Failed to login with Google",
                {
                    className: 'error',
                    position: 'bottom right'
                }
            );
            $scope.googleLogged = false;
            console.log($scope.googleLogged);
        });

    };

我的控制器配置是：

iftttApp.controller('indexController', 
                    ['$scope', '$routeParams', '$window', '$http', function ($scope, $routeParams, $window, $http, ) { ... });

POST成功到達我的servlet，返回成功，但是JSON沒有放入HTTP消息中，POST數據結果為空。 為什么？

嘗試下面的代碼。 實際上您的發布不是正確的密鑰對，在發布請求中的值為json。

$scope.requestGoogleAuth = function() {
        var googleCredentials = {
            email: 'user@domain.com',
            password: 'a2s4d'
        };
        console.log(JSON.stringify(googleCredentials));
        /*$http({
            url: '/MyServlet',
            method: "POST",
            data: JSON.stringify(googleCredentials),
            headers: {'Content-Type': 'application/json'}
        })*/

        var postvalue = {
            "nome": $scope.nome,
            "regione": $scope.regione
        }
        $http.post("/MyServlet", angular.toJson(postvalue)).then(function success(response) {
            $('#loginGoogleModal').modal('hide');
            $("#notificationsWrapper").notify(
                "Logged with Google",
                {
                    className: 'success',
                    position: 'bottom right'
                }
            );
            $scope.googleLogged = true;
            console.log($scope.googleLogged);
        }, function error(response) {
            $('#loginGoogleModal').modal('hide');
            $("#notificationsWrapper").notify(
                "Failed to login with Google",
                {
                    className: 'error',
                    position: 'bottom right'
                }
            );
            $scope.googleLogged = false;
            console.log($scope.googleLogged);
        });

    };
