node.js之分析服务到服务 google-auth-library-nodejs

引用此文档 JSON Web Tokens ，我尝试访问 Analytics Reporting API，首先尝试“应用程序默认凭据”，然后尝试“JSON Web token ”身份验证。
每次我收到错误 Request had insufficient authentication scopes.
我通过 Query Explorer 访问数据没有问题，而且我真的不想使用 OAuth2，因为我一开始只会访问自己的帐户。下面列出的范围来自 Google scopes 中的“Google Analytics API, v3” .

鉴于错误消息，我尝试了其他范围的各种迭代，最值得注意的是“Analytics Reporting API，v4”。
备注 :Google Developers Console 的服务帐户 key 中提供的电子邮件已添加到 Analytics 管理控制台的所有权限(帐户、属性、 View )中。我也尝试过类似“Service <--> Service authentication”中描述的方法。

尝试“应用程序默认凭据”(在 .env 中设置服务帐户 key 的路径):

const {auth} = require('google-auth-library'); 
async function main() { 
  const client = await auth.getClient({ 
    scopes: [ 
      'https://www.googleapis.com/auth/analytics', 
      'https://www.googleapis.com/auth/analytics.edit', 
      'https://www.googleapis.com/auth/analytics.manage.users', 
      'https://www.googleapis.com/auth/analytics.manage.users.readonly', 
      'https://www.googleapis.com/auth/analytics.provision', 
      'https://www.googleapis.com/auth/analytics.readonly', 
      'https://www.googleapis.com/auth/analytics.user.deletion' 
    ] 
  }); 
  const projectId = await auth.getProjectId(); 
  const url = `https://www.googleapis.com/dns/v1/projects/${projectId}`; 
  const res = await client.request({ url }); 
  console.log(res.data); 
} 
main().catch(console.error); 

const {JWT} = require('google-auth-library'); 
const keys = require('../service-account-credentials.json'); 
 
async function main() { 
  console.log('keys.client_email: ', keys.client_email) 
  console.log('keys.private_key: ', keys.private_key) 
  const client = new JWT( 
    keys.client_email, 
    null, 
    keys.private_key, 
    [ 
    'https://www.googleapis.com/auth/analytics', 
    'https://www.googleapis.com/auth/analytics.edit', 
    'https://www.googleapis.com/auth/analytics.manage.users', 
    'https://www.googleapis.com/auth/analytics.manage.users.readonly', 
    'https://www.googleapis.com/auth/analytics.provision', 
    'https://www.googleapis.com/auth/analytics.readonly', 
    'https://www.googleapis.com/auth/analytics.user.deletion' 
    ], 
  ); 
  const url = `https://www.googleapis.com/dns/v1/projects/${keys.project_id}`; 
  const res = await client.request({url}); 
  console.log(res.data); 
  const tokenInfo = await client.getTokenInfo(client.credentials.access_token); 
  console.log(tokenInfo); 
} 
 
main().catch(console.error); 

请您参考如下方法:

样板示例中指定的 url 需要替换为分析查询，例如来自 "API Query URI" 的查询.

例如，如果我想要页面浏览量，我将替换问题片段中使用的 url:
https://www.googleapis.com/dns/v1/projects/${projectId}
使用查询资源管理器中指定的内容:
https://www.googleapis.com/analytics/v3/data/ga?ids=ga%${analyticsViewOrProfileId}&start-date=30daysAgo&end-date=2018-08-28&metrics=ga%3Apageviews&dimensions=ga%3ApagePath&sort=-ga%3Apageviews
结果(功能)代码如下:

const {auth} = require('google-auth-library'); 
 
async function main() { 
  const client = await auth.getClient({ 
    scopes: [ 
      'https://www.googleapis.com/auth/analytics', 
      'https://www.googleapis.com/auth/analytics.readonly' 
    ] 
  }); 
  const viewId = <VIEW ID FROM ANALYTICS CONSOLE> 
  const url = `https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A${viewId}&start-date=30daysAgo&end-date=2018-08-28&metrics=ga%3Apageviews&dimensions=ga%3ApagePath&sort=-ga%3Apageviews`; 
  const res = await client.request({ url }); 
  console.log(res.data); 
} 
main().catch(console.error);
