Question

我正在使用AWS CloudAPI调用AWS Lambda存储库，以实现Google（AoG）上的操作。使用Google-Actions NodeJS客户端，一切正常，除了从AoG模拟器调用时出现错误时，错误消息是“ ...目前无响应。请稍后重试”。

node.js AWS Lambda代码如下，

const { dialogflow } = require('actions-on-google'),
    AWS = require('aws-sdk');

const app = dialogflow({
    debug: true
});

const iotData = new AWS.IotData({
    endpoint: '***thing_id***.iot.us-east-1.amazonaws.com'
}),
    name = '***thing_name***',

    /** The parameters required to retrieve the state of the endpoint */
    paramsToGetThing = {
        thingName: name
    };

/**
 * Notify the AWS IoT endpoint on command
 * @param {DialogflowConversation} conv DialogflowConversation instance
 * @return {void}
 */
app.intent('Notify IoT Intent', (conv) => {
    console.log('Inside Notify IoT Intent function');

    return new Promise((resolve, reject) => {
        iotData.getThingShadow(paramsToGetThing, function (error, data) {
            if (error) {
                console.log(error, error.stack);
                conv.close('Network error! Please try again after some time.');
                reject(error);
            } else {
                const parsing = JSON.parse(data.payload);
                console.log('Parsing state is ' + parsing.state.reported.connected);
                if (parsing.state.reported.connected) {
                    console.log('Device is in online state and publish the command');
                    publishMessageForCommands(conv.action)
                        .then((response) => {
                            console.log('Inside publish message delay case');
                            setTimeout(function () {
                                console.log('Inside delaycheck after 2 seconds timeout function');
                                conv.ask(response);
                                resolve();
                            }, 2000); // Two seconds delay before speech response
                        })
                        .catch((rejectError) => {
                            conv.close(rejectError);
                            console.log('Inside CustomIntentHandler error block.');
                            reject();
                        });
                } else {
                    console.log('Inside publish message before time out\nDevice is offline state and cannot publish the message to ' + name);
                    conv.close('The device is offline, please check the device and try again');
                    reject();
                }
            }
        });
    });
});

/**
 * Error handler block
 * @param {DialogflowConversation} conv DialogflowConversation instance
 * @return {void}
 */
app.catch((conv, error) => {
    console.error(error);
    conv.ask('I encountered a glitch. Can you say that again?');
});

/**
 * Default fallback intent
 * @param {DialogflowConversation} conv DialogflowConversation instance
 * @return {void}
 */
app.fallback((conv) => {
    conv.ask(`I couldn't understand. Can you say that again?`);
});

exports.handler = app;

当我深入研究问题时，发现AWS部分是干净的，它在dialogflow上运行时也通过了测试，

当我们尝试通过AoG模拟器进行测试时，就会出现问题，

预期的行为是在AoG模拟器中获得响应，但我收到了错误消息。任何帮助将不胜感激。

Answer 1

@Daniel，在AWS Lambda上运行dialogFlow时，我也遇到这个问题。我通过拦截谷歌上的动作响应并仅将正文作为JSON响应发送来解决了该问题。下面是我的示例代码。当dialogFlow只需要JSON时，似乎Google动作sdk希望返回200响应。

Cluster 0 2
Cluster 1 2
Cluster 2 1
Cluster 3 1

响应格式错误：从dialogflow Web挂钩获取响应时出现Webhook错误
