angular-file-upload 是一款轻量级的 AngularJS 文件上传工具，为不支持浏览器的 FileAPI polyfill 设计，使用 HTML5 直接进行文件上传。

特性

• 支持上传进度，在上传的时候，可以取消或者中止，支持文件拖拽（HTML5），目录拖拽（weikit），CORS， PUT(html5)/POST 方法
• 支持使用 Flash polyfill FileAPI 跨浏览器上传 (HTML5 和 non-HTML5) 。允许客户端在上传之前验证或者修改文件。
• 当文件的内容类型使用 $upload.http()时，支持直接上传到 CouchDB，imgur 等等。支持 Angular http POST/PUT 请求的进度事件，更多内容请看 #88(comment)
• Separate shim file loaded on demand for non-HTML5 code meaning no extra load/code if you just need HTML5 support. (Note that html5-shim.js is still needed for progress event in HTML5 browsers)
• 轻量级，使用常规的 $http 来上传（支持非 HTML5 浏览器），所以提供所有 Angular $http 功能

使用

HTML:

drop files here HTML5 Drop File is not supported! Cancel Upload

JS:

//inject angular file upload directives and service.angular.module('myApp', ['angularFileUpload']);var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
 $scope.onFileSelect = function($files) { //$files: an array of files selected, each file has name, size, and type.
 for (var i = 0; i < $files.length; i++) { var file = $files[i];
 $scope.upload = $upload.upload({
 url: 'server/upload/url', //upload.php script, node.js route, or servlet url
 //method: 'POST' or 'PUT',
 //headers: {'header-key': 'header-value'},
 //withCredentials: true,
 data: {myObj: $scope.myModelObj},
 file: file, // or list of files ($files) for html5 only
 //fileName: 'doc.jpg' or ['1.jpg', '2.jpg', ...] // to modify the name of the file(s)
 // customize file formData name ('Content-Disposition'), server side file variable name.
 //fileFormDataName: myFile, //or a list of names for multiple files (html5). Default is 'file'
 // customize how data is added to formData. See #40#issuecomment-28612000 for sample code
 //formDataAppender: function(formData, key, val){}
 }).progress(function(evt) { console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
 }).success(function(data, status, headers, config) { // file is uploaded successfully
 console.log(data);
 }); //.error(...)
 //.then(success, error, progress);
 // access or attach event listeners to the underlying XMLHttpRequest.
 //.xhr(function(xhr){xhr.upload.addEventListener(...)})
 } /* alternative way of uploading, send the file binary with the file's content-type. Could be used to upload files to CouchDB, imgur, etc... html5 FileReader is needed. It could also be used to monitor the progress of a normal http post/put request with large data*/
 // $scope.upload = $upload.http({...}) see 88#issuecomment-31366487 for sample code.
 };
}];
