Youtube api 由于缺少eurl参数，将某些YouTube视频嵌入UIWebView时出现问题

我正在标准iOS UIWebView中查看HTML页面。在这个页面中，我有一个标准的YouTube嵌入，如下所示：

<iframe id="video-play" width="624" height="350" src="http://www.youtube.com/embed/hBLf_N-T0vI" allowfullscreen class="hide fade"></iframe>

此操作失败，错误代码为150，错误消息如上所述（在浏览器中可以正常工作，因此使用下面的原始HTTP请求）

如果我将eurl=未知值更改为eurl=http://rubbish.com/ 然后它又起作用了：

http://www.youtube.com/get_video_info?html5=1&video_id=DldaCQby3j4&eurl=http://rubbish.com&ps=native&el=embedded&hl=en_GB

我试着看了看那些失败的视频的特性，但无法找出是什么导致了好视频和坏视频之间的差异。我看过嵌入设置、隐私和跟踪设置以及我能想到的任何其他设置

我的另一个选择是找出如何将eurl参数添加到请求中

救命啊！ 乔恩

如果有人想要完整的HTTP请求/响应：

错误的请求

GET /get_video_info?html5=1&video_id=DldaCQby3j4&eurl=unknown&ps=native&el=embedded&hl=en_GB HTTP/1.1

可能与“声称”的视频有关。YouTube上的一位联系人回复到我们：

“这些视频（有效的）是被宣称的，而其他的则不是，所以 索赔过程中的某些东西导致了问题。”
