javascript - 可能未处理的拒绝 : - When trying to pass data from angularJS to spring MVC

Question

这个错误对我的考验很大。有人可以帮助我做错什么吗？

我有一个脚本，它以 JSON 格式保存几个参数的值。

var mpdApp = angular.module('mpdApp', ['ngAnimate',
    'ngSanitize', 'ui.bootstrap'
]);

mpdApp
    .controller(
        'mpdController',
        [
            '$scope',
            '$rootScope',
            '$http',
            '$window',

            function($scope, $rootScope, $http, $window) {
                $scope.doValidation = function() {

                    var mpdData = {
                        'mpdPolicyNumber': $scope.mpdPolicyNumber,
                        'mpdFirstName': $scope.mpdFirstName,
                        'mpdLastName': $scope.mpdLastName,
                        'mpdAddress': $scope.mpdAddress,
                        'mpdPhoneNumber': $scope.mpdPhoneNumber
                    };

                    console.log(mpdData);

                    $http({
                            'url': '/mpdValidate',
                            'method': 'POST',
                            'headers': {
                                'Content-Type': 'application/json'
                            },
                            'params': mpdData
                        })
                        .then(
                            function(response) {
                                $rootScope.resultMpdData = response.data;
                            });
                };
            }
        ]);

当我尝试通过 POST 将其传递给我的 spring mvc Controller 时，

spring mvc Controller 方法:

@PostMapping(path = "/mpdValidate", produces = "application/json")
    @ResponseBody
    public List<MPDValidationOutputVO> mpdValidate(@RequestParam("mpdPolicyNumber") String mpdPolicyNumber,
            @RequestParam("mpdFirstName") String mpdFirstName, @RequestParam("mpdLastName") String mpdLastName,
            @RequestParam("mpdAddress") String mpdAddress, @RequestParam("mpdPhoneNumber") String mpdPhoneNumber)
            throws JsonParseException, JsonMappingException, IOException {

        System.out.println("*************");
        MPDValidationInputVO mpdValidationInput = new MPDValidationInputVO();
        List<MPDValidationOutputVO> mpdValidationOutput = mpdValidationService.mpdValidate(mpdValidationInput);
        return mpdValidationOutput;
    }

我收到这个错误。

控制台日志:

{mpdPolicyNumber: "werwer", mpdFirstName: "czxc", mpdLastName: "werwe", mpdAddress: "ghhdf", mpdPhoneNumber: "asaa"}

感谢您的帮助。

尝试使用这个变体

$http({
        url: 'request-url',
        method: "POST",
        data: { 'message' : message }
    })

因为url已经是一个参数，你不应该用单引号引用它。
