Chromecast CAF 接收器应用程序中的身份验证

Question

我有一个帮助 URL，在播放它之前要使用令牌进行身份验证。如何将令牌标头添加到接收方 CAF 应用程序？我在文档中进行了搜索，但找不到任何有关接收器 CAF 应用程序的身份验证参考。

在 V2 播放器中，我们可以使用updateSegmentRequestInfo 拦截请求，如下所示，但我不确定如何使用 CAF 应用程序来拦截请求。有人可以帮忙吗？

host.updateSegmentRequestInfo = function(requestInfo) {
            console.log("Inside updateSegmentRequestInfo");
            requestInfo.withCredentials = true;
            requestInfo.headers = {};
            requestInfo.headers['token'] = window.token;
            console.log("token sent");
        };

在播放器加载事件上设置 cookie。

使用此代码：

const context = cast.framework.CastReceiverContext.getInstance();
const playerManager = context.getPlayerManager();
const castOptions = new cast.framework.CastReceiverOptions();

let playbackConfig = (Object.assign(new cast.framework.PlaybackConfig(), playerManager.getPlaybackConfig()));

playerManager.setMessageInterceptor(
cast.framework.messages.MessageType.LOAD,
request => {

  // Set cookies here. 
  // No need to pass cookies into header in each segment.

  //  console.log("content id:", request.media.contentId);
  //  Set your segment valid hls format : below is example:
  //  Refer other format:
  //  https://developers.google.com/cast/docs/reference/caf_receiver/cast.framework.messages#.HlsSegmentFormat

  request.media.hlsSegmentFormat = cast.framework.messages.HlsSegmentFormat.TS;

  return request;
});

playbackConfig.manifestRequestHandler = requestInfo => {
    requestInfo.withCredentials = true;
};

playbackConfig.segmentRequestHandler = requestInfo => {
    requestInfo.withCredentials = true;
  };

playbackConfig.licenseRequestHandler = requestInfo => {
    requestInfo.withCredentials = true;
};

castOptions.playbackConfig = playbackConfig;
context.start(castOptions);
