  Image thumbnail:
  <div ng-sortable="{ group: 'foobar' }">//调整上传后图片顺序
    <img ng-repeat="file in files" ngf-src="/UploadFiles/2021-04-02/file">

js:


(function () {
  'use strict';
  angular.module('todoApp', ['ng-sortable','ngFileUpload'])
  .controller('UploadController', ['$scope','Upload', function ($scope,Upload) {
   $scope.showProgress = false;
 
   $scope.$watch('files', function () {
    $scope.upload($scope.files);
   });//监听files有改变就上传
 
   $scope.upload = function (files) {
    if (files && files.length) {
     for (var i = 0; i < files.length; i++) {
      var file = files[i];
      (function(i){
        return Upload.upload({
         url: '/upload',
        fields: {'username': $scope.username},
        file: file
       }).progress(function (evt) {
        $scope.showProgress = true;
        var progressPercentage = parseInt(100.0 * evt.loaded / evt.total);//上传百分比
        console.log('progress: ' + progressPercentage + '% ' + evt.config.file.name);
       }).success(function (data, status, headers, config) {
        $scope.showProgress = true;
        var url = data.url;
        $scope.files[i].url = url;
        console.log('file ' + config.file.name + 'uploaded. Response: ', data);
        console.log("size:" + (config.file.size/1000).toFixed(2));//一个文件上传成功
       });
      })(i)
     }
    }
   };
  }])
})();




二、然后是我们的后台代码：


1、app.js中设定上传文件缓存地址


var multiparty = require('connect-multiparty');
var config = require('./config').config;
app.use(multiparty({
  uploadDir: path.join(config.upload_dir)
}));



2、上传代码：


exports.uploadImage = function (req, res, next) {
 /*if (!req.session || !req.session.user) {
  res.send({ status: 'forbidden' });
  return;
 }*/
 var file = req.files && req.files.file;
 if (!file) {
  res.send({ status: 'failed', message: 'no file' });
  return;
 }
 //var uid = req.session.user._id.toString();
  var uid = "stone";
 var userDir = path.join(config.upload_dir, uid);
 ndir.mkdir(userDir, function (err) {
  if (err) {
   return next(err);
  }
  var filename = Date.now() + '_' + file.name;
  var savepath = path.resolve(path.join(userDir, filename));
  if (savepath.indexOf(path.resolve(userDir)) !== 0) {
   return res.send({status: 'forbidden'});
  }
  fs.rename(file.path, savepath, function (err) {
   if (err) {
    return next(err);
   }
   var url = '/upload/' + uid + '/' + encodeURIComponent(filename);
   res.send({ status: 'success', url: url });
  });
 });
};




三、调节图片顺序


加入Sortable插件用来拖拽调整上传图片的先后位置


1、引入js：


<script src="/UploadFiles/2021-04-02/Sortable.min.js">

2、html代码：


<div ng-sortable="{ group: 'foobar' }">//调整上传后图片顺序
  <img ng-repeat="file in files" ngf-src="/UploadFiles/2021-04-02/file">
