早上好，我在播放视频时遇到了问题--我正在使用这个软件包玩家：^2.4.5，但是当我打开包含我的视频的屏幕时，它就不起作用了。它给了我一个白色的屏幕

这是我的密码

​

代码语言：javascript
运行
复制
class VideoPlayerScreenState extends State<VideoPlayerScreen> {

  var  controller;
  var youTubVideoPlayerController;

  @override
  void initState() {
    controller = VideoPlayerController.network(
        widget.initialUrl.toString() ?? 'https://samplelib.com/lib/preview/mp4/sample-5s.mp4');
    loadVideoPlayer();
    super.initState();
  }

  loadVideoPlayer() {
    controller.addListener(() {
      setState(() {
        print(widget.initialUrl);  // this working well
      });
    });
    // from here it doesn't work
    controller.initialize().then((value) {
      print("Load Video Player Initialized 1111");
      setState(() {
        print("Load Video Player Initialized 2222");
      });
    });
  }

这是因为www.privilegeapps.com的证书不受信任。您需要将它的证书添加到受信任列表中。安卓解决方案：

  1. 使用克里普：crip print --url=https://privilegeapps.com --format=pem获取证书
  2. 在cert.pem中创建res/raw。将一步获得的证书放入cert.pem中.它必须从-----BEGIN CERTIFICATE-----开始，以-----END CERTIFICATE-----结束。
  3. 在network_security_config.xml /xml中创建。把这些吐露放在里面：
代码语言：javascript
运行
复制
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
    <domain-config>
        <domain includeSubdomains="true">privilegeapps.com</domain>
        <trust-anchors>
            <certificates src="@raw/cert" />
        </trust-anchors>
    </domain-config>
</network-security-config>
  1. 最后，将其添加到Manifest中：
代码语言：javascript
运行
复制
<application
        ...
        android:networkSecurityConfig="@xml/network_security_config">

如果您事先知道域，则此操作有效。如果视频链接来自用户，那么您可以捕获HandshakeException并暂时关闭平台级别的SSL安全性。并在用户观看完视频后重新打开：

代码语言：javascript
运行
复制
    channel.setMethodCallHandler((call, result) -> {
            switch (call.method) {
                case SECURITY_OFF:
                    HttpsURLConnection.setDefaultSSLSocketFactory(unsafeSSLFactory());
                    result.success(null);
                    break;
                case SECURITY_ON:
                    HttpsURLConnection.setDefaultSSLSocketFactory(factory);
            }
        });


    private SSLSocketFactory unsafeSSLFactory() {
        return SSLCertificateSocketFactory.getInsecure(5000, null);
    }
