这是我的HTML表单：
<form name="myForm" ng-submit="">
<input ng-model='file' type="file"/>
<input type="submit" value='Submit'/>
</form>
我想从本地计算机上传图像，并想读取上传文件的内容。我想使用AngularJS进行的所有操作。
当我尝试打印时，$scope.file它的值是未定义的。
Answers:
这里的一些答案建议使用FormData()，但是很遗憾，这是Internet Explorer 9及更低版本中不提供的浏览器对象。如果需要支持那些较旧的浏览器，则需要使用<iframe>或Flash 等备份策略。
已经有许多Angular.js模块可以执行文件上传。这两个对旧版浏览器有明确的支持：
还有其他一些选择：
其中之一应适合您的项目，或者可以使您对如何自己编写代码有所了解。
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>
在您的控制器中定义“添加”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 $resource or do anything else with it
}
r.readAsBinaryString(f);
}
浏览器兼容性
桌面浏览器
Edge 12，Firefox（Gecko）3.6（1.9.2），Chrome 7，Opera * 12.02，Safari 6.0.2
移动浏览器
Firefox（壁虎）32，Chrome 3，Opera * 11.5，Safari 6.1
注意：不建议使用readAsBinaryString（）方法，而应使用readAsArrayBuffer（）。
onloadend回调函数中对其进行处理。您不需要任何库即可使用此API，它已经在您的浏览器中（除非您使用的是非常老的库）。希望这可以帮助。
readAsArrayBuffer方法（仅在Web worker中可用）而不是常规的异步FileReader API？
这是现代的浏览器方式，没有第三方库。适用于所有最新的浏览器。
app.directive('myDirective', function (httpPostFactory) {
return {
restrict: 'A',
scope: true,
link: function (scope, element, attr) {
element.bind('change', function () {
var formData = new FormData();
formData.append('file', element[0].files[0]);
httpPostFactory('upload_image.php', formData, function (callback) {
// recieve image name to use in a ng-src
console.log(callback);
});
});
}
};
});
app.factory('httpPostFactory', function ($http) {
return function (file, data, callback) {
$http({
url: file,
method: "POST",
data: data,
headers: {'Content-Type': undefined}
}).success(function (response) {
callback(response);
});
};
});
HTML：
<input data-my-Directive type="file" name="file">PHP：
if (isset($_FILES['file']) && $_FILES['file']['error'] == 0) {
// uploads image in the folder images
$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = substr(md5(time()), 0, 10) . '.' . end($temp);
move_uploaded_file($_FILES['file']['tmp_name'], 'images/' . $newfilename);
// give callback to your angular code with the image src name
echo json_encode($newfilename);
}

ng-submit动作还是一个表单动作？这本身无能为力
以下是文件上传的工作示例：

在这个函数中，

要么
您可以使用AngularJS检查jQuery文件上传
您可以使用flow.js实现漂亮的文件和文件夹上传。
https://github.com/flowjs/ng-flow
在这里查看演示
http://flowjs.github.io/ng-flow/
它不支持IE7，IE8，IE9，因此您最终必须使用兼容层
使用该onchange事件将输入文件元素传递给函数。
<input type="file" onchange="angular.element(this).scope().fileSelected(this)" />
因此，当用户选择文件时，您无需单击“添加”或“上传”按钮就可以对其进行引用。
$scope.fileSelected = function (element) {
var myFileSelected = element.files[0];
};
我尝试了@Anoyz（正确答案）给出的所有替代方法...最佳解决方案是https://github.com/danialfarid/angular-file-upload
一些功能：
对我来说很好。您只需要注意说明即可。
在服务器端，我使用NodeJ，Express 4和Multer中间件来管理多部分请求。

<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> <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);
});
$http.post('http://localhost:1337/mediaobject/upload',fd,
{
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
}).success(function(d)
{
console.log(d);
})
}
}]);
</script>
<input type=file>默认情况下，该元素不适用于ng-model指令。它需要一个自定义指令：
select-ng-files适用于1的指令的工作演示ng-modelangular.module("app",[]);
angular.module("app").directive("selectNgFiles", function() {
return {
require: "ngModel",
link: function postLink(scope,elem,attrs,ngModel) {
elem.on("change", function(e) {
var files = elem[0].files;
ngModel.$setViewValue(files);
})
}
}
});<script src="//unpkg.com/angular/angular.js"></script>
<body ng-app="app">
<h1>AngularJS Input `type=file` Demo</h1>
<input type="file" select-ng-files ng-model="fileList" multiple>
<h2>Files</h2>
<div ng-repeat="file in fileList">
{{file.name}}
</div>
</body>$http.post从文件列表$scope.upload = function(url, fileList) {
var config = { headers: { 'Content-Type': undefined },
transformResponse: angular.identity
};
var promises = fileList.map(function(file) {
return $http.post(url, file, config);
});
return $q.all(promises);
};发送带有File对象的POST时，进行设置很重要'Content-Type': undefined。然后，XHR send方法将检测File对象并自动设置内容类型。
指令简单
HTML：
<input type="file" file-upload multiple/>JS：
app.directive('fileUpload', function () {
return {
scope: true, //create a new scope
link: function (scope, el, attrs) {
el.bind('change', function (event) {
var files = event.target.files;
//iterate files since 'multiple' may be specified on the element
for (var i = 0;i<files.length;i++) {
//emit event upward
scope.$emit("fileSelected", { file: files[i] });
}
});
}
};在指令中，我们确保创建了新的作用域，然后侦听对文件输入元素所做的更改。当检测到更改时，以文件对象为参数，向所有祖先作用域（向上）发出事件。
在您的控制器中：
$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);
});
});然后在您的ajax调用中：
data: { model: $scope.model, files: $scope.files }http://shazwazza.com/post/uploading-files-and-json-data-in-the-same-request-with-angular-js/
我认为这是角度文件上传：
轻型Angular JS指令可上传文件。
这是DEMO页面。
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您可以使用FormData安全快速的对象：
// 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: $scope.content,
}).success(function(response) {
// Uploading complete
console.log('Request finished', response);
});
}<input type="file" ng-change="contentChanged($event)">，该怎么办？
http://jsfiddle.net/vishalvasani/4hqVu/在chrome和IE中效果很好（如果您在背景图片中稍微更新了CSS）。这用于更新进度条：
scope.progress = Math.round(evt.loaded * 100 / evt.total)但是在FireFox中，虽然文件上传成功，但是在DOM中无法成功更新angular的[percent]数据。
load事件，如果长度是可计算的，则触发进度事件以指示成功上传。github.com/danialfarid/angular-file-upload已经解决了这一问题。
您可以考虑将IaaS用于文件上传，例如Uploadcare。有一个Angular软件包：https : //github.com/uploadcare/angular-uploadcare
从技术上讲，它是作为指令实施的，提供了不同的上载选项以及对小部件中上载的图像的操作：
<uploadcare-widget
ng-model="object.image.info.uuid"
data-public-key="YOURKEYHERE"
data-locale="en"
data-tabs="file url"
data-images-only="true"
data-path-value="true"
data-preview-step="true"
data-clearable="true"
data-multiple="false"
data-crop="400:200"
on-upload-complete="onUCUploadComplete(info)"
on-widget-ready="onUCWidgetReady(widget)"
value="{{ object.image.info.cdnUrl }}"
/>要使用的更多配置选项：https : //uploadcare.com/widget/configure/
我知道这是一个较晚的条目，但是我创建了一个简单的上载指令。您可以立即开始工作！
<input type="file" multiple ng-simple-upload web-api-url="/api/Upload" callback-fn="myCallback" />ng-simple-upload在Github 上提供更多示例，并提供使用Web API的示例。
的HTML
<input type="file" id="file" name='file' onchange="angular.element(this).scope().profileimage(this)" />向您的控制器添加'profileimage（）'方法
$scope.profileimage = function(selectimage) {
console.log(selectimage.files[0]);
var selectfile=selectimage.files[0];
r = new FileReader();
r.onloadend = function (e) {
debugger;
var data = e.target.result;
}
r.readAsBinaryString(selectfile);
}这应该是对@ jquery-guru答案的更新/评论，但由于我没有足够的代表，它会放在这里。它修复了代码现在生成的错误。
https://jsfiddle.net/vzhrqotw/
更改基本上是：
FileUploadCtrl.$inject = ['$scope']
function FileUploadCtrl(scope) {至：
app.controller('FileUploadCtrl', function($scope)
{如果需要，可以随意移动到更合适的位置。
我已经阅读了所有线程，并且HTML5 API解决方案看起来最好。但这会更改我的二进制文件，并以我未调查的方式破坏它们。最适合我的解决方案是：
HTML：
<input type="file" id="msds" ng-model="msds" name="msds"/>
<button ng-click="msds_update()">
Upload
</button>JS：
msds_update = function() {
var f = document.getElementById('msds').files[0],
r = new FileReader();
r.onloadend = function(e) {
var data = e.target.result;
console.log(data);
var fd = new FormData();
fd.append('file', data);
fd.append('file_name', f.name);
$http.post('server_handler.php', fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
console.log('success');
})
.error(function(){
console.log('error');
});
};
r.readAsDataURL(f);
}服务器端（PHP）：
$file_content = $_POST['file'];
$file_content = substr($file_content,
strlen('data:text/plain;base64,'));
$file_content = base64_decode($file_content);我可以使用以下代码使用AngularJS上传文件：
在file为需要传递的函数的参数ngUploadFileUpload是$scope.file按你的问题。
这里的重点是使用transformRequest: []。这样可以防止$ http弄乱文件的内容。
function getFileBuffer(file) {
var deferred = new $q.defer();
var reader = new FileReader();
reader.onloadend = function (e) {
deferred.resolve(e.target.result);
}
reader.onerror = function (e) {
deferred.reject(e.target.error);
}
reader.readAsArrayBuffer(file);
return deferred.promise;
}
function ngUploadFileUpload(endPointUrl, file) {
var deferred = new $q.defer();
getFileBuffer(file).then(function (arrayBuffer) {
$http({
method: 'POST',
url: endPointUrl,
headers: {
"accept": "application/json;odata=verbose",
'X-RequestDigest': spContext.securityValidation,
"content-length": arrayBuffer.byteLength
},
data: arrayBuffer,
transformRequest: []
}).then(function (data) {
deferred.resolve(data);
}, function (error) {
deferred.reject(error);
console.error("Error", error)
});
}, function (error) {
console.error("Error", error)
});
return deferred.promise;
}以上接受的答案与浏览器不兼容。如果有人遇到兼容性问题，请尝试此操作。
查看代码
<div ng-controller="MyCtrl">
<input type="file" id="file" name="file"/>
<br>
<button ng-click="add()">Add</button>
<p>{{data}}</p>
</div>控制器代码
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.data = 'none';
$scope.add = function(){
var f = document.getElementById('file').files[0],
r = new FileReader();
r.onloadend = function(e){
var binary = "";
var bytes = new Uint8Array(e.target.result);
var length = bytes.byteLength;
for (var i = 0; i < length; i++)
{
binary += String.fromCharCode(bytes[i]);
}
$scope.data = (binary).toString();
alert($scope.data);
}
r.readAsArrayBuffer(f);
}
}简单来说
在HTML中- 仅添加以下代码
<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>在控制器中 -单击 “上传文件按钮”时将调用此功能。它将上传文件。您可以进行控制台。
$scope.uploadedFile = function(element) {
$scope.$apply(function($scope) {
$scope.files = element.files;
});
}在控制器中添加更多 -下面的代码添加到函数中。当您单击用于 “点击api（POST）”的按钮时，将调用此函数 。它将发送文件（上传的文件）和表单数据到后端。
var url = httpURL + "/reporttojson"
var files=$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..我添加了以下代码作为表单数据
var data ={
msg : message,
sub : sub,
sendMail: sendMail,
selectUsersAcknowledge:false
};<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;
}我们使用了HTML，CSS和AngularJS。以下示例显示了如何使用AngularJS上传文件。

</div>
<script>
var myApp = angular.module('myApp', []);
myApp.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};
}]);
myApp.service('fileUpload', ['$http', function ($http) {
this.uploadFileToUrl = function(file, uploadUrl){
var fd = new FormData();
fd.append('file', file);
$http.post(uploadUrl, fd, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
})
.error(function(){
});
}
}]);
myApp.controller('myCtrl', ['$scope', 'fileUpload', function($scope, fileUpload){
$scope.uploadFile = function(){
var file = $scope.myFile;
console.log('file is ' );
console.dir(file);
var uploadUrl = "/fileUpload";
fileUpload.uploadFileToUrl(file, uploadUrl);
};
}]);
</script>
</body>
</html>使用简单指令（ng-file-model）的工作示例：
.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]);
});
}
}
}])并用于FormData上传功能中的文件。
var formData = new FormData();
formData.append("document", $scope.ngFileModel.data)
formData.append("user_id", $scope.userId)所有的积分都用于 https://github.com/mistralworks/ng-file-model
