如何迭代alexa输出的语音？

Question

我正在尝试迭代 alexa 的语音输出

for(var i = 0; i< status.passengers.length; i++) {
                    console.log("----inside getJson--------->",status.passengers[i].current_status);
                    let reservationStauts = status.passengers[i].current_status;

                    statusWords = reservationStauts.split("/");
                    for(var j=0; j < statusWords.length; j++) {
                        confirmStatus = statusWords[0];
                        statusNumber = statusWords[2];
                    }
                    passenger = status.passengers[i].no;
                    speechOutput = "the p n r status for passenger "+passenger+" is "+confirmStatus+statusNumber;
                    callback(session.attributes, buildSpeechletResponse(cardTitle, speechOutput, "", false));
                }

但由于回调更改了控制器，我无法获得语音输出的第二次迭代。

基本上我正在尝试迭代语音输出！

这里确实没有什么是 Alexa 独有的，而是 javascript 和回调处理问题。诀窍是除非绝对必要，否则不要调用回调。
在这种情况下，因为看起来您正在尝试构建包含多个模式信息的响应，所以您可能最好将回调移到最外层的 for 循环之外。

我已尝试更新您的以下代码段：
注意：我还将 speechOutput 的声明移到了循环之外，这样您就可以在循环的每次迭代中构建它

let speechOutput = ''; // need to declare this outside the loop and treat the loop as your speech builder
for(var i = 0; i< status.passengers.length; i++) {
    console.log("----inside getJson--------->",status.passengers[i].current_status);
    let reservationStauts = status.passengers[i].current_status;

    statusWords = reservationStauts.split("/");
    for(var j=0; j < statusWords.length; j++) {
        confirmStatus = statusWords[0];
        statusNumber = statusWords[2];
    }
    passenger = status.passengers[i].no;
    speechOutput += "the p n r status for passenger "+passenger+" is "+confirmStatus+statusNumber;
    speechOutput += ',\n'; //SINCE you're looping over multiples - should probably throw some sort of speach separator/pause here

}
callback(session.attributes, buildSpeechletResponse(cardTitle, speechOutput, "", false));
