  var uploader=$scope.uploader=new FileUploader();/*实例化一个FileUploader对象*/
    uploader.url='/carrots-admin-ajax/a/u/img/task';/*以下是设置了两个必须的属性*/
    uploader.queue=[];

/*以下是上传过程中以及结束后所做的处理动作，可以只拿自己需要的部分，最好将这些都放到一个service中*/

    uploader.onWhenAddingFileFailed = function(item /*{File|FileLikeObject}*/, filter, options) {
      console.info('onWhenAddingFileFailed', item, filter, options);
    };
    uploader.onAfterAddingFile = function(fileItem) {
      console.info('onAfterAddingFile', fileItem);
    };
    uploader.onAfterAddingAll = function(addedFileItems) {
      console.info('onAfterAddingAll', addedFileItems);
    };
    uploader.onBeforeUploadItem = function(item) {
      console.info('onBeforeUploadItem', item);
    };
    uploader.onProgressItem = function(fileItem, progress) {
      console.info('onProgressItem', fileItem, progress);
    };
    uploader.onProgressAll = function(progress) {
      console.info('onProgressAll', progress);
    };
    uploader.onSuccessItem = function(fileItem, response, status, headers) {
      // alert(response)
      console.info('onSuccessItem', response.data.url);
    };
    uploader.onErrorItem = function(fileItem, response, status, headers) {
      console.info('onErrorItem', fileItem, response, status, headers);
    };
    uploader.onCancelItem = function(fileItem, response, status, headers) {
