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);
    });
}

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:

上传文件

<input type="file" name="resume" onchange="angular.element(this).scope().uploadResume()" ng-model="fileupload" id="resume" />


        $scope.uploadResume = function () { 
            var f = document.getElementById('resume').files[0];
            $scope.selectedResumeName = f.name;
            $scope.selectedResumeType = f.type;
            r = new FileReader();

            r.onloadend = function (e) { 
                $scope.data = e.target.result;
            }

            r.readAsDataURL(f);

        };

下载文件:

          <a href="{{applicant.resume}}" download> download resume</a>

var app = angular.module("myApp", []);

            app.config(['$compileProvider', function ($compileProvider) {
                $compileProvider.aHrefSanitizationWhitelist(/^\s*(https?|local|data|chrome-extension):/);
                $compileProvider.imgSrcSanitizationWhitelist(/^\s*(https?|local|data|chrome-extension):/);

            }]);

你可以使用flow.js实现良好的文件和文件夹上传。

https://github.com/flowjs/ng-flow

点击这里查看演示

http://flowjs.github.io/ng-flow/

它不支持IE7, IE8, IE9，所以你最终必须使用兼容层

简单的指令

Html:

<input type="file" file-upload multiple/>

JS:

app.directive('fileUpload', function () {
return {
    scope: true,        //create a new scope
    link: function (scope, el, attrs) {
        el.bind('change', function (event) {
            var files = event.target.files;
            //iterate files since 'multiple' may be specified on the element
            for (var i = 0;i<files.length;i++) {
                //emit event upward
                scope.$emit("fileSelected", { file: files[i] });
            }                                       
        });
    }
};

在指令中，我们确保创建了一个新的作用域，然后监听对文件输入元素所做的更改。当检测到更改时，以文件对象作为参数向所有祖先作用域(向上)发出事件。

在你的控制器中:

$scope.files = [];

//listen for the file selected event
$scope.$on("fileSelected", function (event, args) {
    $scope.$apply(function () {            
        //add the file object to the scope's files collection
        $scope.files.push(args.file);
    });
});

然后在ajax调用中:

data: { model: $scope.model, files: $scope.files }

下面是文件上传的工作示例:

在这个函数中

setFiles

从视图更新控制器中的文件数组

你可以使用AngularJS检查jQuery文件上传
