IBM Watson无法向API进行身份验证

Question

不是使用curl，而是遵循node.js教程，使用IBM Watson tone analyzer为slack构建情绪分析应用程序。我的process.env已经拥有来自IBM的凭证，就像伦敦的实例url一样：

TONE_ANALYZER_IAM_APIKEY=<MY API KEY>
TONE_ANALYZER_URL=https://api.eu-gb.tone-analyzer.watson.cloud.ibm.com/instances/c2f8238d- 
cf7a-4184-9bc2-315e0a204d3a

The index.js

const ToneAnalyzerV3 = require('watson-developer-cloud/tone-analyzer/v3');
const toneAnalyzer = new ToneAnalyzerV3({
  iam_apikey: process.env.TONE_ANALYZER_IAM_APIKEY,
  url: 'https://api.eu-gb.tone-analyzer.watson.cloud.ibm.com/instances/c2f8238d-cf7a-4184- 
  9bc2-315e0a204d3a',
version: '2017-09-21',

我仍然收到这个错误

Error: Insufficient credentials provided in constructor argument. Refer to the documentation 
for the required parameters. Common examples are username/password and iam_access_token.

我尝试使用IBM Watson仪表板中的“管理”和“服务凭据”选项卡中的两个API密钥--它们都不起作用。有谁有什么想法吗？

Answer 1

试着用这种方式

Watson APIs Node.js SDK

import AssistantV1 from 'ibm-watson/assistant/v1';
import { IamAuthenticator } from 'ibm-watson/auth';

export const createAssistant = configs => new AssistantV1({
  authenticator: new IamAuthenticator({ apikey: configs.apiKey }),
  url: configs.url,
  version: '2019-02-28'
});

有关身份验证的更多信息，请参阅https://cloud.ibm.com/apidocs/tone-analyzer?code=node#authentication上的SDK参考。
