對於我的Rails應用程序，我有項目，用戶可以通過Redactor Rails發佈更新。我爲每個項目製作了BLOGPOSTS控制器和型號。現在，他們可以用這款富文本編輯器嵌入視頻。但是，我正在探索添加一個選項，允許用戶直接在我的網站上使用YouTube進行網絡攝像機錄製並將其上傳到YouTube並作爲項目的BLOGPOST發佈。 Blogposts目前被保存在blogupdates表中，作爲t.text "content"。Youtube Webcam Widget - 抓取視頻ID
我在這裏引用文檔：https://developers.google.com/youtube/youtube_upload_widget
* *問題：當我加入的YouTube上傳控件，它顯示了網絡攝像頭。然後錄製，之後，它只會生成上傳的視頻進行播放。但是有沒有辦法讓我抓住視頻ID，並在錄製視頻後自動保存爲帶有嵌入html的「BLOGPOST」content？
所以我增加了以下每個項目頁面：
視圖/項目/ show.html.erb
<script>
// 2. Asynchronously load the Upload Widget and Player API code.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. Define global variables for the widget and the player.
// The function loads the widget after the JavaScript code
// has downloaded and defines event handlers for callback
// notifications related to the widget.
var widget;
var player;
function onYouTubeIframeAPIReady() {
widget = new YT.UploadWidget('widget', {
width: 500,
events: {
'onUploadSuccess': onUploadSuccess,
'onProcessingComplete': onProcessingComplete
}
});
}
// 4. This function is called when a video has been successfully uploaded.
function onUploadSuccess(event) {
alert('Video ID ' + event.data.videoId + ' was uploaded and is currently being processed.');
}
// 5. This function is called when a video has been successfully
// processed.
function onProcessingComplete(event) {
player = new YT.Player('player', {
height: 390,
width: 640,
videoId: event.data.videoId,
events: {}
});
}
</script>
<div class = "container">
<div id="widget"></div>
<div id="player"></div>
</div>
此外，每個頁面顯示的修訂者Rails的形式：
<%= form_for([@project, @project.blogposts.build]) do |f| %>
<div class="field">
<%= f.text_area :content, label: "Blog Posts", :class => "redactor", %>
</div>
<%= f.hidden_field :user_id, :value => current_user.id %>
<div class="actions">
<%= f.submit "Add Blog Post", :class => "btn btn-header" %>
</div>
<% end %>
blogposts_controller.rb
def create
@project = Project.find(params[:project_id])
params[:blogpost][:content] = sanitize_redactor(params[:blogpost][:content])
@blogpost = @project.blogposts.create!(params[:blogpost])
if @blogpost.save
redirect_to blogs_project_path(@project), notice: "Blog entry created."
end
end
schema.rb
create_table "blogposts", :force => true do |t|
t.integer "user_id"
t.integer "project_id"
t.text "content"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
