Question

我正在尝试历史虚张声势的例子来调用维基百科服务。我将呼叫置于开始消息中。我可以看到它正在打印我的消息，直到它点击呼叫stmt。但它在控制台中没有打印任何内容。代码如下所示：

var https = require('https');
var urlPrefix = 'https://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&explaintext=&exsectionformat=plain&redirects=&titles=';

HowTo.prototype.eventHandlers.onLaunch = function (launchRequest, session, response) {
     console.log("vik::::::::::::: before service call ");


    var speechText = "Welcome to the your assistant? ... what can I help you with.";
    var repromptText = "For instructions on what you can say, say help me.";
    response.ask(speechText, repromptText);
     getJsonEventsFromWikipedia("day", "date", function (events) {
        console.log("vik::::::::::::: wikipedia response received");
        console.log("values are:" + events);
    });
};


function getJsonEventsFromWikipedia(day, date, eventCallback) {
    var url = urlPrefix+'Jan_21';
     console.log("url to invoke is:" + url);

    https.get(url, function(res) {
        console.log("vik:::::::::::::::::::::inside data fetch");
        var body = '';

        res.on('data', function (chunk) {
            body += chunk;
        });

        res.on('end', function () {
            var stringResult = body;
            eventCallback(stringResult);
        });
    }).on('error', function (e) {
        console.log("Got error: ", e);
    });
}

控制台打印如

我不确定有什么问题以及如何调试

Answer 1

现在有效。问题是测试我把它放在启动意图和响应卡后面。这是调用context.succeed并在它完成之前将其杀死。
