致電 Amazon Lookout for Vision 操作

運行以下代碼以確認您可以撥打電話到 Amazon Lookout for Vision API。該代碼列出了您的項目 AWS 帳戶，在目前 AWS 區域。如果您之前尚未建立專案，則回應為空白，但確認您可以呼叫該 ListProjects操作。

通常，調用示例函數需要 AWS SDK Lookout for Vision 客戶端和任何其他必需的參數。Lo AWS SDK okout for Vision 客戶端在主要功能中聲明。

如果程式碼失敗，請檢查您使用的使用者是否擁有正確的權限。還要檢查 AWS 您用作 Amazon Lookout for Vision 區域並非所有區域都可用 AWS 區域。

致電 Amazon Lookout for Vision 操作

1. 如果您尚未這樣做，請安裝並配置 AWS CLI 和 AWS SDKs。如需詳細資訊，請參閱步驟 4：設定 AWS CLI 以及 AWS SDKs。

2. 使用以下的範例程式碼來檢視您的專案。

   CLI

   使用 list-projects 指令列出您帳戶中的專案。

   aws lookoutvision list-projects \
   --profile lookoutvision-access
