Question

我从Google Analytics API v3获取数据

https://www.googleapis.com/analytics/v3/data/ga?ids=ga:181335694&metrics=ga:sessions&start-date=7daysAgo&end-date=today

一旦我运行浏览器就会抛出错误

{
   "error":{
      "errors":[
         {
            "domain":"global",
            "reason":"required",
            "message":"Login Required",
            "locationType":"header",
            "location":"Authorization"
         }
      ],
      "code":401,
      "message":"Login Required"
   }
}

如何解决此错误？

一旦我运行python代码，我就会获得Google Analytics（分析）api，但是我在浏览器中运行时抛出登录错误，这是解决该问题所必需的。

在谈论Google API时，有两种类型的数据。

任何人和所有人都不拥有的公共数据数据可以查看用户拥有的私人数据，您必须具有访问权限。

“需要登录”，

完全表示您必须经过身份验证才能访问您尝试访问的数据。您需要该数据所有者的许可。您不能只获取该获取字符串并在需要访问令牌的浏览器中将其启动就可以做到这一点。您将从身份验证流程中获取访问令牌。

自从您提到python以来，您应该遵循hello analytics tutorial，它将向您展示如何设置项目和验证脚本，以便您可以访问所需的数据。
