Google Cloud Vision - 無法加載默認憑據

我正在使用PHP庫來使用Google Cloud Vision。該文檔講述了兩種認證方式 - 1）API和2）服務帳戶。Google Cloud Vision - 無法加載默認憑據

如何使用我的VisionClient使用基於API的身份驗證？沒有使用它的文件。如果我錯了，請讓我知道。

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

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

    $vision->annotate($image);

運行上述代碼時出現以下錯誤消息。

對不起。它不是。它只說有關使用服務帳戶而不使用API密鑰。 – Purus

這可以幫到您嗎？ https://developers.google.com/identity/protocols/application-default-credentials https://cloud.google.com/vision/docs/reference/libraries#client-libraries-install-php http：///terrenceryan.com/blog/index.php/working-with-cloud-vision-api-from-php/ – Osoter

如果您計劃在本地繼續運行，可以通過運行gcloud auth application-default login命令進行身份驗證，然後使用Cloud Vision API客戶端庫運行您的服務。請參閱使用客戶端庫section瞭解更多詳細信息。
