我正在使用AngularJs和Firebase构建一个小型网络应用程序(类似博客文章)。我之前实现了addPost控制器并且运行良好。之后我想在表单中添加一个输入文件,该表单已经实现了使用 ng-file-upload指令在表单提交上将图像上传到firebase。作为一个新的角度我知道firebase可以将图像保存为base64但我无法弄清楚如何使其工作。 也许有些人会说这是一再重复的问题,但相信我,我在这里搜索全身心,我可以找到答案 这是我的表单文件:
<div class="container" ng-controller="AddPostCtrl">
<form class="form-horizontal" ng-submit="AddPost(files)">
<fieldset>
<!-- Form Name -->
<legend>Create Post</legend>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="txtTitle">Title</label>
<div class="col-md-4">
<input id="txtTitle" name="txtTitle" ng-model="article.title" type="text" placeholder="placeholder" class="form-control input-md">
</div>
</div>
<!-- Textarea -->
<div class="form-group">
<label class="col-md-4 control-label" for="txtPost">Post</label>
<div class="col-md-4">
<textarea class="form-control" id="txtPost" ng-model="article.post" name="txtPost"></textarea>
</div>
</div>
<!-- Images -->
<div class="form-group">
<label class="col-md-4 control-label" for="pictures">Add Pictures</label>
<div class="col-md-4">
<input id="pictures" type="file" ngf-select ng-model="files" name="file"
accept="image/*" ngf-max-size="2MB" ngf-multiple="true" ngf-keep="true" ngf-keep-distinct="true" class="btn btn-primary"/>
<!-- Show image thumb and remove option -->
<span ng-repeat="file in files">
<img ngf-thumbnail="!file.$error && file" class="thumb"> <button class="btn btn-danger" ng-click="file = null" ng-show="file">Remove</button>
</span>
</div>
</div>
<!-- Button -->
<div class="form-group">
<label class="col-md-4 control-label" for="singlebutton"></label>
<div class="col-md-4">
<input id="singlebutton" ng-disabled="!article.title || !article.post" name="singlebutton" class="btn btn-primary" type="submit" value="Publish" />
</div>
</div>
</fieldset>
</form>
</div>
这是我的控制器:
angular.module('myApp.addPost', ['ngRoute'])
.controller('AddPostCtrl', ['$scope','CommonProp','$firebase','$location','Upload','$timeout', function($scope,CommonProp,$firebase,$location,Upload,$timeout) {
if(!CommonProp.getUser()){
$location.path('/main');
}
/***** Add data to firebase *****/
$scope.AddPost = function(files) {
var fb = new Firebase("https://hotelboard.firebaseio.com/Articles/");
var title = $scope.article.title;
var post = $scope.article.post;
var user = CommonProp.getUser();
var images = Upload.base64DataUrl(files).then(function(base64Urls){
fb.push({
title: title,
post: post,
emailId: user,
images : base64Urls,
'.priority': user
},function(error) {
if (error) {
console.log("Error:",error);
} else {
console.log("Post set successfully!");
console.log(images);
$location.path('/home');
$scope.$apply();
}
});
});
}
}]);

如果我在这个问题上得到帮助,那么对结果的质疑就会更多。 请帮助
更新: @danialfarid更新了指令并让我的日子成为了一天:)
升级到8.0.6并将你的fb推送到这里:
Upload.base64DataUrl(files).then(function(base64Urls) {
fb.push({...
images : base64Urls,
},...
});
我也更新了代码。

将你的fb推送到这里:
Upload.base64DataUrl(files).then(function(base64Urls) {
fb.push({...
images : base64Urls,
},...
});
Upload.base64DataUrl会将文件转换为base64数据网址,然后可以将其添加到json中发送给服务器。
