使用API​​密钥分析报告v4

标签: c# asp.net google-api google-analytics-api google-api-dotnet-client

我需要在我使用asp.net网络表单(C#)构建的CMS Web应用程序的仪表板页面中集成Google Analytics的一个非常基本的报告。

我记得我能够在2015年使用API​​ V3进行的测试中做到这一点,但是现在,使用V4,我总是收到一条错误消息,认证需要OAuth2。

  

我需要访问我拥有的特定分析帐户,而不是在CMS中导航的用户帐户!

所以我使用Google API Manager提供的API KEY。我已经给了API Key所有权限。 API密钥类似于:“d471c3ce04612f143ff0Be319aac2e17d0159add”

这是代码

@Component({
  selector: 'my-app',
  template: `
    <div>
      <input type="text" 
        *ngFor="let name of names; let nameIndex = index; trackBy: trackByIndex"
        [(ngModel)]="names[nameIndex]"/>
      <br/>
      {{ names | json }}
    </div>
  `,
})
export class App {

  names: string[];

  constructor() {
    this.names = ['a', 'b', 'c'];
  }

  public trackByIndex(index: number, item) {
    return index;
  }
}

在Test()方法的最后一行, ars.Reports.BatchGet(getReport).Execute(); 我收到错误:

  

Google.Apis.Requests.RequestError   请求缺少必需的身份验证凭据。预期的OAuth 2访问令牌,登录cookie或其他有效的身份验证凭据。

但是再次使用OAUTH2身份验证我访问用户数据并不是我想要的。 我需要访问我拥有的特定帐户,由浏览CMS的用户独立访问。

API密钥仅用于访问公共数据,这意味着您只能将其与metadata api一起使用。

Google Analytics数据是用户拥有的私有数据。由于这是您尝试访问的自己的数据,因此您应该创建一个服务帐户。服务帐户是预先授权的。转到Google开发人员控制台并创建service account credentials。然后获取服务帐户电子邮件地址,并将其作为用户添加到Google Analytics分析网站管理部分的ACCOUNT级别。它必须是ACCOUNT级别。您现在已授权服务帐户访问该帐户的数据。

服务帐户验证
