Question

我的代码给我错误

Cannot read property 'SessionRequest' of undefined
    at initializeCastApi

我不知道发生了什么事。本质上，当我单击复选框时，会发出请求，并且客户应用程序将显示在Chrome Cast中。我什至无法开始会议。

    if (!chrome.cast || !chrome.cast.isAvailable) {
        setTimeout(initializeCastApi, 1000);
    }

    /**

     */
    function initializeCastApi() {
        console.log("initializeCastApi : " + applicationID);
        var sessionRequest = new chrome.cast.SessionRequest(applicationID);
        var apiConfig = new chrome.cast.ApiConfig(sessionRequest,
                sessionListener, receiverListener);

        chrome.cast.initialize(apiConfig, onInitSuccess, onError);
    };

无法在initializeCastApi读取未定义的属性“ SessionRequest”
