javascript - 在 Google Action 意图中发送 GET 请求

Question

我是 Google 和 Node.js 上的 Actions 新手，但这看起来应该很简单，但我不确定为什么它不起作用。我只想在处理特定意图的代码中发送 GET 请求。目前，我什至不寻找返回值；我只是想取消这个请求。我正在使用 Firebase 的 Blaze 层，它应该允许传出 HTTPS 请求。事实上，我可以通过 SSML 获取从我的服务器播放音频文件的操作。但是，当我向 PHP 页面发出 GET 请求以增加数据库中的值时，它没有成功执行。

我的代码直接取自 Google 的 CodeLabs 操作教程。以下是我正在修改的唯一功能。此代码运行，但从未收到 GET 请求。

// Handle the Dialogflow intent named 'favorite color'.
// The intent collects a parameter named 'color'.
app.intent('favorite color', (conv, {color}) => {
    const luckyNumber = color.length;
    const audioSound = 'https://my.server.tld/path/to/sound.mp3';

    // These two lines don't seem to do what I'm expecting them to.
    var https = require("https");
    https.get('https://my.server.tld/path/to/file.php?value=1');

    conv.ask(`<speak>Your lucky number is ${luckyNumber}.` +
        `<audio src="${audioSound}"></audio>` +
        `Would you like to hear some fake colors?</speak>`);
});

Firebase 日志中没有任何异常之处(摘录如下)。似乎没有提到我试图进行的 GET 调用。

Answer 1

我想我已经发现了为什么我会遇到这个问题，以及为什么我无法根据对 Google 或 Node.js 上的 Actions 的研究来解释它。看起来我请求的服务器上的页面返回了 301“永久移动”响应。当我通过 Web 浏览器请求该页面时，它会忽略(？)此响应并提供该页面，但是当我在 AoG 意图实现中发出请求时，它会默默地识别出 301 并且永远不会命中页面上的 PHP服务器。不管怎样，看来这是我的服务器配置的问题，而不是我的 AoG 代码的问题。

给新 AoG 程序员的重要提示:执行中的 console.log() 命令将出现在 Firebase Cloud Functions 日志中，这最终让我看到了返回的 301 代码。感谢任何试图与我一起解决这个问题的人!
