android - 由于 “Cross origin requests”，YouTube中的Webview播放失败

转载作者：行者123 更新时间：2023-12-03 05:25:00

问题

尝试从webview(android 5.0)内播放视频会导致许多“跨源请求”失败，并且视频无法播放。
但是，在Google Chrome浏览器和笔记本电脑上，以下HTML可以使视频完美播放!

HTML

<!DOCTYPE html>
<html>
    <head>
        <style>
            html{width:100%;height:100%;}
            body{margin:0;width:100%;height:100%;background-color:black;}
        </style>
    </head>
    <body>
        <div id='player'></div>
        <script> 
            var playerLoaded = false;
            var percentReported = 0;
            var percentCurrent = 0;
            var tag = document.createElement('script');
            tag.src = 'http://www.youtube.com/player_api'; 
            var firstScriptTag = document.getElementsByTagName('script')[0];
            firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
            var player; 

            function onYouTubePlayerAPIReady() { 
                playerLoaded = true;
                player = new YT.Player('player', { 
                    width:'100%', 
                    height:'100%', 
                    videoId:'CpaOh4poNms', 
                    playerVars: { playsinline: 1 }, 
                    events: { 
                        'onReady': onPlayerReady, 
                        'onStateChange': onPlayerStateChange, 
                        'onError': onPlayerError 
                    }
                }); 
            }

            function onPlayerReady(event) { 
                event.target.playVideo(); 
                setInterval(onPlayerTimeUpdate, 1000); 
            }

            function onPlayerStateChange(event) {
                if (event.data == YT.PlayerState.ENDED) {
                } 
            }

            function onPlayerError(event) {
            }

            function onPlayerTimeUpdate() { 
                percentCurrent = Math.round(player.getCurrentTime() / player.getDuration() * 100); 
                if (percentCurrent > percentReported) { 
                     percentReported = percentCurrent; 
                }
            }

            setTimeout(function() { 
                if (!playerLoaded) { 
                } 
            }, 10000);
        </script> 
    </body>
</html>

如何初始化Webview

@SuppressLint("SetJavaScriptEnabled")

    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setUseWideViewPort(false);

        webSettings.setAllowFileAccessFromFileURLs(true);
        webSettings.setAllowUniversalAccessFromFileURLs(true);
    }

    webView.setBackgroundColor(Color.TRANSPARENT);
    webView.setVerticalScrollBarEnabled(false);
    webView.setHorizontalScrollBarEnabled(false);
    webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

}

private FrameLayout.LayoutParams COVER_SCREEN_GRAVITY_CENTER = new FrameLayout.LayoutParams(
        ViewGroup.LayoutParams.WRAP_CONTENT,
        ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.CENTER);

    // this will allow the webview to play embedded video and full screen video
    mYoutubeVideoViewContainer = (FrameLayout) findViewById(R.id.fullscreen_youtube_video);
    mWebChromeClient = new WebChromeClient() {

        {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);

            // if a view already exists then immediately terminate the new one
            if (mCustomView != null)
            {
                callback.onCustomViewHidden();
                return;
            }

            // Add the custom view to its container.
            mYoutubeVideoViewContainer.addView(view, COVER_SCREEN_GRAVITY_CENTER);
            mCustomView = view;
            mCustomViewCallback = callback;

            // hide main browser view
            mContentFlipper.setVisibility(View.GONE);

            // Finally show the custom view container.
            mYoutubeVideoViewContainer.setVisibility(View.VISIBLE);
            mYoutubeVideoViewContainer.bringToFront();
        }

        @Override
        public void onHideCustomView()
        {
            if (mCustomView == null) {
                return;
            }

            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

            // Hide the custom view.

            // Remove the custom view from its container.
            mYoutubeVideoViewContainer.removeView(mCustomView);

        }
    };
    mTargetWebView.setWebChromeClient(mWebChromeClient);
    mTargetWebView.setWebViewClient(new WebViewClient());

如何将HTML加载到Webview中

mTargetWebView.loadDataWithBaseURL("http://www.youtube.com", youtubeHTML, "text/html", "utf-8", null);

布局XML

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/fullscreen_youtube_video"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#FF000000">

        <ViewSwitcher
            android:id="@+id/contentFlipper"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >

            <WebView
                android:id="@+id/youtubeWebview"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@android:color/white" />

        </ViewSwitcher>

    </FrameLayout>

</RelativeLayout>

我想念什么？

进行中...

我可以使此废话在Android(5.0)的webview上运行的唯一方法是使用以下HTML ...

<html>
<body>
<iframe width="100%" height="100%" src="http://www.youtube.com/embed/CpaOh4poNms?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>
</body>
</html>

至少这将显示视频播放器。整个动态div至iframe废话在Android上完全不起作用: https://developers.google.com/youtube/iframe_api_reference#Getting_Started

最佳答案

我已经计算出onYouTubeIframeAPIReady()和onYouTubePlayerAPIReady()是，从来没有在Android上称为。

我想知道这是否是故意强制人们切换到YouTube Library-如果库不依赖于YouTube应用程序，我会这样做。
我认为该库应该有“胖”和“瘦”版本；精简版取决于youtube应用，胖版则可选。

为了使视频自动播放，我使用以下代码:
https://stackoverflow.com/a/27722504/550471
并从onPageFinished()触发它

要将HTML加载到WebView中，我正在使用:webView.loadDataWithBaseURL("http://www.youtube.com", youtubeHTML, "text/html; charset=utf-8", "UTF-8", null);
HTML包含:

<html>
<head></head>
<body>
<iframe id="player" width="100%" height="100%" src="http://www.youtube.com/embed/CpaOh4poNms?rel=0&origin=youtube.com" frameborder="0" allowfullscreen></iframe>
</body>
</html>
