angularJs上传文件（非form上传）

angular.js:13920 Broken interceptor detected: Config object not supplied in rejection:

<input type="file" id="file{{$index}}" class="file" ngf-select ngf-change="cacScriptUploadVm.views.changeAttach($file,$index)">

　　　　function save() {
            console.log(vm.views.scriptList);
            var form = new FormData();
            for (var i = 0; i < vm.views.scriptList.length; i++) {
                var file = angular.element(".file")[i].files[0];
                form.append("files", file);//files和后台接收字段名称一样
            }
            //传入出了file以外的实体
            /* var scriptList = JSON.stringify(vm.views.scriptList);
            form.append("script", scriptList);*/
            form.append("newDir","");//传一个字符串
            cacScriptService.uploadFile(form);           

        }

        function changeAttach($file, $index) {
            if ($file != null && vm.views.scriptList.length > 0 && vm.views.scriptList.length >= $index) {
                vm.views.files[$index] = $file;

                method: ‘POST‘,
                url: url,

            });
        }
