【问题描述】：

我正在尝试为我的 Google 广告获取报告并将其显示在仪表板上以便于查看和监控。

我已经完成了对我的帐户进行身份验证的整个过程。我得到了所有需要的钥匙。 一切正常，直到查询运行。请参阅下面从Google ads API examples复制的代码

没有任何东西打印到我的控制台。当我打印出print(response) 我得到<google.api_core.grpc_helpers._StreamingResponseIterator object at 0x7fb7dcaaf3d0>

我没有收到任何错误，没有任何回溯。这是我的控制台的样子（隐藏 customer_id）：

【问题讨论】：

看起来一切正常。您的 Google 广告帐户是否可能没有广告系列？

尝试打印len(response)并检查是否为0。

@RitwikG 是的，我公司的谷歌广告帐户有 50 多个广告系列。这就是为什么我觉得它无法打印任何东西很奇怪。

@RitwikG TypeError: '_StreamingResponseIterator' 类型的对象没有 len()

MCC 没有广告系列，只有帐户有。您需要传递实际的帐户 ID，而不是您的 MCC ID。

【参考方案1】：

它实际上是返回值，你可以使用它。

 for batch in response:
    for row in batch.results:
        print(
            f"Campaign with ID row.campaign.id and name "
            f'"row.campaign.name" was found.'
        )

【讨论】：

对我来说，它没有返回任何值。程序运行，没有打印任何内容。这意味着查询没有结果。然而，关联的帐户上有多个广告系列。
