AngularJS中文社区angular 怎么上传文件

Answer 1

利用angular-file-upload组件就可以了。
angular-file-upload 是一个基于HTML5技术的文件上传轻量级 AngularJS指令（directive），当浏览器不支持时转为采用 FileAPI polyfill技术实现(基于Flash)。
参考:
//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.
};
}];
