javascript - 通过 AngularJS 上传多个文件到 Laravel Controller

Question

---

我有

浏览文件按钮

<input type="file" upload-files multiple />

创建按钮

<button class="btn btn-link" ng-click="store()" >Create</button>

---

指令

myApp.directive('uploadFiles', function () {
    return {
        scope: true,
        link: function (scope, element, attrs) {
            element.bind('change', function (event) {
                var files = event.target.files;
                for (var i = 0; i < files.length; i++) {
                    scope.$emit("seletedFile", { file: files[i] });
                }
            });
        }
    };
});

---

监听选择的文件

$scope.files = [];
$scope.$on("seletedFile", function (event, args) {

    console.log("event is ", event);
    console.log("args is ", args);

    $scope.$apply(function () {
        $scope.files.push(args.file);
    });

});

发布数据和选定的文件。

$scope.store = function() {

    $scope.model = {
      name: $scope.name,
      type: $scope.type
    };

    $http({
        method: 'POST',
        url: '/image/store',
        headers: { 'Content-Type': undefined },
        transformRequest: function (data) {
            console.log("data coming into the transform is ", data);
            var formData = new FormData();
            formData.append("model", angular.toJson(data.model));
            for (var i = 0; i < data.files; i++) {
                formData.append("file" + i, data.files[i]);
            }
            return formData;
        },

        data: { model: $scope.model, files: $scope.files }

    })


    .then(function successCallback(response) {
        console.log("%cSuccess!", "color: green;");
        console.log(response);
        $scope.refresh();
        $scope.showModal = false;
        }, function errorCallback(response) {
        console.log("%cError", "color: red;");
        console.log(response);
    });
};

结果

在我的控制台中，我没有看到我的文件在后端传递到我的 Controller 。

array:1 [
  "model" => "{"type":"wedding"}"
]

问题

我忘记了什么步骤？

如何进一步调试它？

Answer 1

我做过几个angular 1的项目，也发现通过$http api上传文件并不简单。希望我在我的项目中使用的以下代码片段可以帮助您。

$scope.store = function() {
  var formData = new FormData();

  // add normal properties, the name should be the same as
  // what you would use in a html form
  formData.append('model[name]', $scope.name);
  formData.append('model[type]', $scope.type);

  // add files to form data.
  for (var i = 0; i < $scope.files; i++) {
    formData.append('file' + i, $scope.files[i]);
  }

  // Don't forget the config object below
  $http.post('/image/store', formData, {
    transformRequest: angular.identity,
    headers: {'Content-Type': undefined}
  }).then(function() {
    // ...
  });
};
