我是新來的平均堆棧。我想知道如何通過AngularJS將圖像文件上傳到數據庫（貓鼬）。請如果你能提供一些代碼。我已經在網上搜索，我發現這個代碼，但它不工作對我來說如何上傳圖像並使用mean.js將其保存到數據庫（貓鼬）
HTML代碼：
<div class="col-md-4 col-xs-8">
<div class="fileinput fileinput-new" data-provides="fileinput">
<img class="profile-pic thumbnail" style="width: 200px; height: 150px;" />
<div>
<span class="btn btn-default btn-file">
<span class="fileinput-new upload-button"><span class="glyphicon glyphicon-upload"></span> Upload New Pic</span>
<input class="file-upload" type="file" data-ng-file-select="onFileSelect($files)" accept="image/png, image/jpeg" >
</span>
</div>
<span data-ng-if="uploadInProgress">Upload progress: {{ uploadProgress }}</span>
<img data-ng-src="uploadedImage" data-ng-if="uploadedImage">
<br>
</div>
</div>
客戶方controller.js：
$scope.onFileSelect = function(image) {
console.log("image selected" + image);
if (angular.isArray(image)) {
image = image[0];
}
// This is how I handle file types in client side
if (image.type !== 'image/png' && image.type !== 'image/jpeg') {
alert('Only PNG and JPEG are accepted.');
return;
}
$scope.uploadInProgress = true;
$scope.uploadProgress = 0;
$scope.upload = $upload.upload({
url: '/upload/image',
method: 'POST',
file: image
}).progress(function(event) {
$scope.uploadProgress = Math.floor(event.loaded/event.total);
$scope.$apply();
}).success(function(data, status, headers, config) {
$scope.uploadInProgress = false;
// If you need uploaded file immediately
$scope.uploadedImage = JSON.parse(data);
}).error(function(err) {
$scope.uploadInProgress = false;
console.log('Error uploading file: ' + err.message || err);
});
};
我的問題甚至在選擇文件後控制器沒有觸發。我還保留了一個控制檯來測試，但它不起作用。
