我创建了一个带有并发 gcloud 应用程序的 Dialogflow 代理。但是,当我尝试将其集成到 Node.js 后端时,它似乎访问了错误的应用程序默认凭据。

我可以确认它正在验证身份验证是否成功,因为它在我运行此代码时控制台记录了正确的项目 ID (diagnosistest-56e81):

// Imports the Google Cloud client library.
const Storage = require('@google-cloud/storage')

// Instantiates a client. If you don't specify credentials when constructing
// the client, the client library will look for credentials in the
// environment.
const storage = new Storage();

// Makes an authenticated API request.
storage
  .getBuckets()
  .then((results) => {
    const buckets = results[0];

    console.log('Buckets:');
    buckets.forEach((bucket) => {
      console.log(bucket.name);
    });
  })
  .catch((err) => {
    console.error('ERROR:', err);
  })

但是,当我尝试连接 dialogflow 时,出现错误。

连接到对话流的代码:

// You can find your project ID in your Dialogflow agent settings
const projectId = 'diagnosistest-56e81'; //https://dialogflow.com/docs/agents#settings
const sessionId = 'quickstart-session-id';
const query = 'hello';
const languageCode = 'en-US';

// Instantiate a DialogFlow client.
const dialogflow = require('dialogflow');
const sessionClient = new dialogflow.SessionsClient();

// Define session path
const sessionPath = sessionClient.sessionPath(projectId, sessionId);

// The text query request.
const request = {
  session: sessionPath,
  queryInput: {
    text: {
      text: query,
      languageCode: languageCode,
    },
  },
};

// Send request and log result
sessionClient
  .detectIntent(request)
  .then(responses => {
    console.log('Detected intent');
    const result = responses[0].queryResult;
    console.log(`  Query: ${result.queryText}`);
    console.log(`  Response: ${result.fulfillmentText}`);
    if (result.intent) {
      console.log(`  Intent: ${result.intent.displayName}`);
    } else {
      console.log(`  No intent matched.`);
    }
  })
  .catch(err => {
    console.error('ERROR:', err);
  });

我收到的错误消息:

ERROR: { Error: 7 PERMISSION_DENIED: Dialogflow API has not been used in project 764086051850 before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/dialogflow.googleapis.com/overview?project=764086051850 then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry.

奇怪的是,我的项目编号是 889800549397 而不是 764086051850。所以它似乎没有访问正确的凭据。

到目前为止我已经尝试过:

  1. 通过创建新的 Dialogflow 服务帐户密钥并将导出设置为 json 密钥文件export GOOGLE_APPLICATION_CREDENTIALS='/Users/Joseph/workspace/finddoc/DiagnosisTest-cred.json
  2. 删除application_default_credentials.json文件./config/gcloud/夹中的文件。

当我这样做时,我收到一条不同的错误消息:

ERROR: Error: Unexpected error while acquiring application default credentials: Could not load the default credentials. Browse to https://developers.google.com/accounts/docs/application-default-credentials for more information.

终于知道问题出在哪里了。设置好环境变量GOOGLE_APPLICATION_CREDENTIALS后,必须重启电脑才能生效!

尝试使用 Dialogflow V2 API 时,我在本地计算机上遇到了完全相同的错误消息(包括 764086051850 项目 ID)。我不想打扰GOOGLE_APPLICATION_CREDENTIALS环境变量,所以我按照这里的说明进行操作。

具体来说,这部分很重要:

API 启用和配额由主应用程序默认凭据项目管理。如果出现与 API 未启用或配额限制相关的错误,请使用 --client-id-file 标志。您可以在https://console.cloud.google.com/apis/credentials创建客户端 ID 文件。

我最终运行的命令:

gcloud auth application-default login --client-id-file=my_app_client_id.json

这会将应用程序默认凭据保存到您的主目录中的文件中。例如:/Users/nathanb/.config/gcloud/application_default_credentials.json
