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

它不支持IE7, IE8, IE9，所以你最终必须使用兼容层

您的文件和json数据同时上传。

// FIRST SOLUTION var _post = function (file, jsonData) { $http({ url: your url, method: "POST", headers: { 'Content-Type': undefined }, transformRequest: function (data) { var formData = new FormData(); formData.append("model", angular.toJson(data.model)); formData.append("file", data.files); return formData; }, data: { model: jsonData, files: file } }).then(function (response) { ; }); } // END OF FIRST SOLUTION // SECOND SOLUTION // If you can add plural file and If above code give an error. // You can try following code var _post = function (file, jsonData) { $http({ url: your url, method: "POST", headers: { 'Content-Type': undefined }, transformRequest: function (data) { var formData = new FormData(); formData.append("model", angular.toJson(data.model)); for (var i = 0; i < data.files.length; i++) { // add each file to // the form data and iteratively name them formData.append("file" + i, data.files[i]); } return formData; }, data: { model: jsonData, files: file } }).then(function (response) { ; }); } // END OF SECOND SOLUTION

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/

<form id="csv_file_form" ng-submit="submit_import_csv()" method="POST" enctype="multipart/form-data">
    <input ng-model='file' type="file"/>
    <input type="submit" value='Submit'/>
</form>

在angularJS控制器中

$scope.submit_import_csv = function(){

        var formData = new FormData(document.getElementById("csv_file_form"));
        console.log(formData);

        $.ajax({
            url: "import",
            type: 'POST',
            data:  formData,
            mimeType:"multipart/form-data",
            contentType: false,
            cache: false,
            processData:false,
            success: function(result, textStatus, jqXHR)
            {
            console.log(result);
            }
        });

        return false;
    }

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 }

最简单的是使用HTML5 API，即FileReader

HTML非常简单:

<input type="file" id="file" name="file"/>
<button ng-click="add()">Add</button>

在你的控制器中定义'add'方法:

$scope.add = function() {
    var f = document.getElementById('file').files[0],
        r = new FileReader();

    r.onloadend = function(e) {
      var data = e.target.result;
      //send your binary data via $http or $resource or do anything else with it
    }

    r.readAsBinaryString(f);
}

浏览器兼容性

桌面浏览器

Edge 12, Firefox(Gecko) 3.6(1.9.2)， Chrome 7, Opera* 12.02, Safari 6.0.2

移动浏览器

注意:readAsBinaryString()方法已弃用，应该使用readAsArrayBuffer()代替。
