Is there any way to send image via JSON to an api?

Question:

I want to send an image (I'll save it in a database), but I don't know how to send it together in POST .

I'm using AngularJs :

<input type="file" ng-model="user.imageProfile">

---

$scope.register = function (user) {

    if (user.password != user.passwordConfirm) {
        $rootScope.showToast("Confirmação de senha inválida!");
        return null;
    }

    $http.post($rootScope.serviceBase + "users", user).then(function () {
        $rootScope.showToast("Cadastrado com sucesso");
        $mdDialog.cancel();
    });
};

Answer:

I decided to convert the image to Base64 , I used angular-base64-upload , it looked like this:

Input:

<input type="file" ng-model="image" base-sixty-four-input>

Controller:

$scope.register = function (user) {
    if (user.password != user.passwordConfirm) {
        $rootScope.showToast("Confirmação de senha inválida!");
        return null;
    }

    $scope.user.imageProfile = $scope.image.base64;

    $http.post($rootScope.serviceBase + "users", user).then(function () {
        $rootScope.showToast("Cadastrado com sucesso");
        $mdDialog.cancel();
    });
};

Exhibition:

<img data-ng-src="data:image/png;base64,{{ userAuthenticated.imageProfile }}" title="{{ userAuthenticated.name }}" class="photoUser" data-err-src="images/png/avatar.png"/>
