Python 向GoogleAnalyticisAPI发出请求时，需要登录

我从谷歌分析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一个错误

{
   "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，我就会得到Google Analytics api，但我在浏览器中运行时会抛出错误，因为需要登录才能解决它。

当我们谈论Google api时，有两种类型的数据

不属于任何人和每个人都可以查看的公共数据 用户拥有的私有数据，您必须具有访问该数据的权限

“需要登录”

这意味着您必须通过身份验证才能访问您试图访问的数据。您需要该数据所有者的权限。你不能只是拿着那个get字符串在浏览器中启动它，你需要一个访问令牌才能做到这一点。您可以从身份验证流获取访问令牌

既然您提到了python，那么您应该遵循下面的步骤，这将向您展示如何设置项目和验证脚本，以便能够访问所需的数据

我怀疑如何设置json文件路径。get_service（'analytics'，'v3'，scope，'client_secrets.json'）SystemExit:客户端机密无效：客户端类型“web”中缺少属性“redirect_URI”。警告：请配置OAuth 2.0确保下载了corect client_secrets.json文件，并按照有关如何创建该文件的教程进行操作。确保其与正在运行的脚本位于同一文件夹中
