我正在使用Google分析嵌入Api https://ga-dev-tools.appspot.com/embed-api/third-party-visualizations/ 在我的网站中可视化仪表板，但我没有成功。
我正在执行下面的代码，结果是空白容器并出现错误，即未捕获＃cb = gapi.loaded_0：109 我无法看到任何图表我的网页。

我通过向gapi.analytics.auth.authorize（）添加 acces_token 来解决我的问题，我们可以通过在Google Analytics中创建服务帐户来获取access_token。 https://ga-dev-tools.appspot.com/embed-api/server-side-authorization/
通过运行一个轰鸣声java类，我获得了访问令牌
public static String getToken() throws FileNotFoundException, IOException
{
GoogleCredential credential = GoogleCredential
.fromStream(new FileInputStream("/path-to-file/xxx-246d0882d022.json"))
.createScoped(Collections.singleton(AnalyticsScopes.ANALYTICS_READONLY));
credential.refreshToken();
access_token=credential.getAccessToken();
System.out.println(access_token);
return access_token;
}
创建服务帐户后，您将获得服务帐户邮件ID，您必须在用户管理中添加此邮件ID，并且必须在您的帐户中启用google analytics api。
