我正在使用nervgh的角度文件上传https://github.com/nervgh/angular-file-upload/wiki/Module-API。
有没有办法在进行多文件上传时使用angular-file-upload并允许每个文件的附加属性?
我使用他们的图片示例开始:http://nervgh.github.io/pages/angular-file-upload/examples/image-preview/
尝试为用户可以设置的每个文件添加一个布尔值,然后在拾取时在服务器端使用它。

问题相当陈旧,但由于文档对我没有多大帮助,我想在此处记下我的解决方案:
这就是我的html的样子(寻找“选项”):
<div ng-controller="UploadCtrl2" nv-file-drop="" uploader="uploader" filters="customFilter">
<div class="progress progress-xs margin-top-5 margin-bottom-20">
<div class="progress-bar" role="progressbar" ng-style="{ 'width': uploader.progress + '%' }"></div>
</div>
<div class="row">
<div class="col-md-6">
<div ng-show="uploader.isHTML5">
<div class="well my-drop-zone" nv-file-drop="" options="{formData:[{folder:'attachments'}, {recordid:0}]}" uploader="uploader">
Dateien hierher ziehen.
</div>
</div>
</div>
<div class="col-md-6">
<span class="btn btn-primary btn-o btn-file margin-bottom-15"> Dateien auswählen
<input type="file" nv-file-select="" options="{formData:[{folder:'attachments'}, {recordid:0}]}" uploader="uploader" multiple />
</span>
</div>
</div>
</div>
这是我的控制器(寻找“fileItemOptions”):
app.controller('UploadCtrl2', ['$rootScope', '$scope', 'FileUploader', 'Store',
function ($rootScope, $scope, FileUploader, Store) {
var fileItemOptions = {};
var uploader = $scope.uploader = new FileUploader({
url: $rootScope.app.api.url + '/?c=uploads&a=set&authToken=' + encodeURIComponent(Store.get('X-Xsrf-Token')),
});
// FILTERS
uploader.filters.push({
name: 'customFilter',
fn: function (item/*{File|FileLikeObject}*/, options) {
if(options) fileItemOptions = options;
return this.queue.length < 10;
}
});
uploader.removeAfterUpload = true;
// CALLBACKS
uploader.onAfterAddingFile = function (fileItem, options) {
//console.info('onAfterAddingFile', fileItem);
if(fileItemOptions.formData) {
fileItem.formData = fileItemOptions.formData;
}
};
uploader.onAfterAddingAll = function (addedFileItems) {
setTimeout(function () {
console.log(uploader);
uploader.uploadAll();
}, 500);
};
uploader.onCompleteAll = function () {
$scope.$parent.run.uploadComplete();
fileItemOptions = {}; // cleanup
};
}]);
每当添加文件时,自定义过滤器都会将选项对象存储在全局变量中。回调“onAfterAddingFile”将读取该变量并将其读取到fileItem对象。非常hacky,但这是我让它运行的唯一方式。
