Google Cloud Vision - 无法加载默认凭据

Question

我正在使用 PHP 库来使用 Google Cloud Vision。该文档讲述了 2 种身份验证方式 - 1) API 和 2) 服务帐户。

如何在我的 VisionClient 中使用基于 API 的身份验证？没有关于使用它的文档。如果我错了，请告诉我。

    $vision = new VisionClient([
        'projectId' => 'ophoto'
    ]);

    $image = $vision->image($photoResource, 
             ['LABEL_DETECTION','SAFE_SEARCH_DETECTION','IMAGE_PROPERTIES']);

    $vision->annotate($image);

运行上述代码时，我收到以下错误消息。

请找到here 一个使用 PHP 语言的 Cloud Vision API 的几个示例！

希望对你有帮助！

Answer 2

如果您打算继续在本地运行它，您可以通过运行gcloud auth application-default login 命令进行身份验证，然后使用 Cloud Vision API 客户端库来运行您的服务。有关更多详细信息，请参阅此使用客户端库 section。
