这应该是对@jquery-guru的答案的更新/评论，但由于我没有足够的代表，它将在这里。它修复了现在由代码生成的错误。

变化主要是:

FileUploadCtrl.$inject = ['$scope']
function FileUploadCtrl(scope) {

To:

app.controller('FileUploadCtrl', function($scope)
{

如果需要，请随意搬到更合适的地方。

这是现代浏览器的方式，没有第三方库。适用于所有最新的浏览器。

 app.directive('myDirective', function (httpPostFactory) {
    return {
        restrict: 'A',
        scope: true,
        link: function (scope, element, attr) {

            element.bind('change', function () {
                var formData = new FormData();
                formData.append('file', element[0].files[0]);
                httpPostFactory('upload_image.php', formData, function (callback) {
                   // recieve image name to use in a ng-src 
                    console.log(callback);
                });
            });

        }
    };
});

app.factory('httpPostFactory', function ($http) {
    return function (file, data, callback) {
        $http({
            url: file,
            method: "POST",
            data: data,
            headers: {'Content-Type': undefined}
        }).success(function (response) {
            callback(response);
        });
    };
});

HTML:

<input data-my-Directive type="file" name="file">

PHP:

如果收取(带有_file美元['文件'])& & $带有_file(“文件”)(“错误”)= = 0){ //上传images文件夹中的image $temp =爆炸("."，$_FILES["file"]["name"]); $newfilename = substr(md5(time())， 0,10)。”。”。结束(临时); 函数(带有_file美元(“文件”)(“tmp_name”),“图像/”。美元newfilename); //给你的angular代码回调图像SRC名称 回声json_encode ($ newfilename); ｝ Js小提琴(仅前端) https://jsfiddle.net/vince123/8d18tsey/31/

使用简单指令的示例(ng-file-model):

.directive("ngFileModel", [function () {
  return {
      $scope: {
          ngFileModel: "="
      },
      link: function ($scope:any, element, attributes) {
          element.bind("change", function (changeEvent:any) {
              var reader = new FileReader();
              reader.onload = function (loadEvent) {
                  $scope.$apply(function () {
                      $scope.ngFileModel = {
                          lastModified: changeEvent.target.files[0].lastModified,
                          lastModifiedDate: changeEvent.target.files[0].lastModifiedDate,
                          name: changeEvent.target.files[0].name,
                          size: changeEvent.target.files[0].size,
                          type: changeEvent.target.files[0].type,
                          data: changeEvent.target.files[0]
                      };
                  });
              }
              reader.readAsDataURL(changeEvent.target.files[0]);
          });
      }
  }
}])

并使用FormData在函数中上传文件。

var formData = new FormData();
 formData.append("document", $scope.ngFileModel.data)
 formData.append("user_id", $scope.userId)

我遇到了一个小问题，你可以在这里查看: https://github.com/mistralworks/ng-file-model/issues/7

最后，这里是一个分叉的回购:https://github.com/okasha93/ng-file-model/blob/patch-1/ng-file-model.js

你可以使用一个安全快速的FormData对象:

// Store the file object when input field is changed
$scope.contentChanged = function(event){
    if (!event.files.length)
        return null;

    $scope.content = new FormData();
    $scope.content.append('fileUpload', event.files[0]); 
    $scope.$apply();
}

// Upload the file over HTTP
$scope.upload = function(){
    $http({
        method: 'POST', 
        url: '/remote/url',
        headers: {'Content-Type': undefined },
        data: $scope.content,
    }).success(function(response) {
        // Uploading complete
        console.log('Request finished', response);
    });
}

简单地说

在Html中-只添加以下代码

     <form name="upload" class="form" data-ng-submit="addFile()">
  <input type="file" name="file" multiple 
 onchange="angular.element(this).scope().uploadedFile(this)" />
 <button type="submit">Upload </button>
</form>

当你点击“上传文件按钮”时，这个函数被调用。它将上传文件。你可以安慰它。

$scope.uploadedFile = function(element) {
$scope.$apply(function($scope) {
  $scope.files = element.files;         
});
}

在控制器中添加更多-以下代码添加到函数中。这个函数在你点击按钮时被调用，这个按钮被用来“命中api (POST)”。它将发送文件(上传)和表单数据到后端。

var url = httpURL + "/reporttojson"
        var files=$scope.files;

         for ( var i = 0; i < files.length; i++)
         {
            var fd = new FormData();
             angular.forEach(files,function(file){
             fd.append('file',file);
             });
             var data ={
              msg : message,
              sub : sub,
              sendMail: sendMail,
              selectUsersAcknowledge:false
             };

             fd.append("data", JSON.stringify(data));
              $http.post(url, fd, {
               withCredentials : false,
               headers : {
                'Content-Type' : undefined
               },
             transformRequest : angular.identity
             }).success(function(data)
             {
                  toastr.success("Notification sent successfully","",{timeOut: 2000});
                  $scope.removereport()
                   $timeout(function() {
                    location.reload();
                }, 1000);

             }).error(function(data)
             {
              toastr.success("Error in Sending Notification","",{timeOut: 2000});
              $scope.removereport()
             });
        }

在这种情况下…我添加了下面的代码作为表单数据

var data ={
          msg : message,
          sub : sub,
          sendMail: sendMail,
          selectUsersAcknowledge:false
         };

HTML

<html>
    <head></head>

<body ng-app = "myApp">

  <form ng-controller = "myCtrl">
     <input type = "file" file-model="files" multiple/>
     <button ng-click = "uploadFile()">upload me</button>
     <li ng-repeat="file in files">{{file.name}}</li>
  </form>

脚本

  <script src = 
     "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
  <script>
    angular.module('myApp', []).directive('fileModel', ['$parse', function ($parse) {
        return {
           restrict: 'A',
           link: function(scope, element, attrs) {
              element.bind('change', function(){
              $parse(attrs.fileModel).assign(scope,element[0].files)
                 scope.$apply();
              });
           }
        };
     }]).controller('myCtrl', ['$scope', '$http', function($scope, $http){


       $scope.uploadFile=function(){
       var fd=new FormData();
        console.log($scope.files);
        angular.forEach($scope.files,function(file){
        fd.append('file',file);
        });
       $http.post('http://localhost:1337/mediaobject/upload',fd,
           {
               transformRequest: angular.identity,
               headers: {'Content-Type': undefined}                     
            }).success(function(d)
                {
                    console.log(d);
                })         
       }
     }]);
