Question

我正在尝试创建一个Alexa技能，根据Alexa设备的位置在Web服务上查找位置。

我已经完成了所有代码，因为我可以在日志中看到正确的输出，但我正在努力解决的一件事就是让语音输出工作。

非常感谢任何帮助。我对NodeJS很新。我觉得这与在https.request中调用tell有关，但我现在不知道如何解决这个问题。

代码：

deviceAddressRequest.then((addressResponse) => {
    switch(addressResponse.statusCode) {
        case 200:
            console.log("Address successfully retrieved, now responding to user.");
            const address = addressResponse.address;
            const postcode = `${address['postalCode']}`;

            // Get JSON response

            console.info("test begin");

            var post_data =
            {
                "postcode":
                "`${address['postalCode']}`"
            };
            console.info ('Users postcode is ' + postcode);
            var post_options = {
                host:  '[redacted]',
                port: '443',
                path: '/alexa/address.php?postcode=' + encodeURI(postcode),
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                    'Content-Length': Buffer.byteLength(JSON.stringify(post_data))
                }
            };
            console.info ('Post options set');
            var post_req = https.request(post_options, function(res) {
                res.setEncoding('utf8');
                var returnData = "";
                res.on('data', function (chunk) {
                    returnData += chunk;
                });
                res.on('end', function () {
                    console.info("Data returned!")
                    console.info('returnData: ' + returnData);
                    var nearBoutique = JSON.parse(returnData).location1;
                    console.info("Nearest location: " + nearLocation);
                    const ADDRESS_MESSAGE = "Your nearest location is: " + nearLocation;
                });
            });
            post_req.write(JSON.stringify(post_data));
            post_req.end();
            console.info(ADDRESS_MESSAGE);
            // I tried it here, and also under the "const ADDRESS_MESSAGE"
            this.emit(":tell", ADDRESS_MESSAGE);
            break;
        case 204:
            console.log("Successfully requested from the device address API, but no address was returned.");
            this.emit(":tell", Messages.NO_ADDRESS);
            break;
        case 403:
            console.log("The consent token we had wasn't authorized to access the user's address.");
            this.emit(":tellWithPermissionCard", Messages.NOTIFY_MISSING_PERMISSIONS, PERMISSIONS);
            break;
        default:
            this.emit(":ask", Messages.LOCATION_FAILURE, Messages.LOCATION_FAILURE);
    }

    console.info("Ending getAddressHandler()");
});

我不是在寻找一个直接的解决方案，但是正确方向的指针会很棒。
