Dialogflow简单的授权方式

Question

是否存在将Dialogflow代理连接到我的node.js代码的简单方法？当我使用此代码与Dialogflow代理的设置页面中的正确projectID时,我有以下错误:

错误:获取应用程序默认凭据时出现意外错误:无法加载默认凭据.有关详细信息,请浏览到https://developers.google.com/accounts/docs/application-default-credentials.

const sessionClient = new dialogflow.SessionsClient();
const sessionPath = sessionClient.sessionPath(projectId, sessionId);

我访问了该页面,但是我想要的是我认为很混乱(他们引用其他API和很多设置),我该如何解决这个问题？

我想这样做从文件中获取信息并加载所有信息而不安装API或其他一些...

Answer 1

它没有很好的文档记录,但最简单的身份验证方法是使用Google云平台控制台上提供的JSON文件.

const sessionClient = new dialogflow.SessionsClient({
    keyFilename: '/path/to/google.json'
});
const sessionPath = sessionClient.sessionPath(projectId, sessionId);

这也适用于所有其他客户.ContextsClients,EntityTypesClient等等.

Answer 2

我正在编写代码，这对我有用。请按照参考链接 2 中提供的所有步骤进行操作，出于编码目的，您可以使用提供的代码段。

我还添加了 Google Cloud Oauth 的示例 JSON
