在离子框架中将视频上传到Firebase uing ngCordova（$ cordovaCapture） [英] Uploading video to Firebase uing ngCordova ($cordovaCapture) in ionic framework

问题描述

如何上传我使用手机录制的视频。我设法将视频路径上传到Firebase，但是当我想在我的视图（html文件）中使用它时，它不起作用。这是我的代码：

How to upload video that I record using my mobile. I manage to upload the video path to Firebase but when I want to use it in my view (html file), it does not work. Here is my code:

.controller("HomeCtrl", function($scope, $firebaseArray, $cordovaCamera, $location, $cordovaCapture){
  var fb = new Firebase("https://myURL.firebaseio.com/videos");
  $scope.videos;
  $scope.record = function(){
      fb = new Firebase("https://myURL.firebaseio.com/videos");
      $scope.videos = $firebaseArray(fb);
      var options = { limit: 1, duration: 15 };
      $cordovaCapture.captureVideo(options).then(
          function(videoData) {
              var i, path, len;
              var pathtogo;
              var pathtogostring;
              for (i = 0, len = videoData.length; i < len; i += 1) {
                  path = videoData[i].fullPath;
                  pathtogo = path.toString();
                  pathtogostring = pathtogo.substr(6);  
                  alert("Path of the video is = " + path.toString());                                      

                  obj = {
                      videoP: path,
                      videosrc: pathtogostring
                  }
                  $scope.videos.$add(obj);
                }
          },
          function(err) {
          }
      );
  }//end record
 })//end controller 

我的html文件

  <div ng-repeat="video in videos" class="card">

    <div class="item item-text-wrap">
        {{video.videoP}}
    </div>

    <div class="item item-text-wrap">
        {{video.videosrc}}
    </div>

    <video controls>
        <source src="video.videosrc" type="video/mp4">
    </video>
</div>

推荐答案

如果不自行运行应用程序很难说，但是我确实看到你的记录函数存在问题。

It's hard to tell without running the app myself, but I do see an issue with your record function.

不要初始化 $ firebaseArray 在记录函数内部，在控制器初始化时执行：

Don't initialize the $firebaseArray inside of the record function, do it when the controller initializes:

.controller("HomeCtrl", function($scope, $firebaseArray, $cordovaCamera, $location, $cordovaCapture){
  var fb = new Firebase("https://myURL.firebaseio.com/videos");
  $scope.videos = $firebaseArray(fb);
  $scope.record = function record() {
     // ... your record code here 
  };
})

$ firebaseArray 与服务器同步，因此只需要创建一次。

The $firebaseArray is in sync with the server, so it only needs to be created once.

至于您的显示问题...

您需要更改< source> <中的 src 属性/ code>到 ng-src ，并使用卷曲 {{}} 进行插值：

You need to change the src attribute in <source> to ng-src, and use curlys {{ }} to interpolate:

<video controls>
    <source ng-src="{{video.videosrc}}" type="video/mp4">
</video>
