配置環境變量

配置環境變量ALIBABA_CLOUD_ACCESS_KEY_IDALIBABA_CLOUD_ACCESS_KEY_SECRET

重要
  • 阿里云賬號AccessKey擁有所有API的訪問權限,建議您使用RAM用戶進行API訪問或日常運維,具體操作,請參見創建RAM用戶

  • 請不要將AccessKey ID和AccessKey Secret保存到工程代碼里,否則可能導致AccessKey泄露,威脅您賬號下所有資源的安全。

  • Linux和macOS系統配置方法

    1. 在IntelliJ IDEA中打開終端Terminal。

    2. 執行以下命令,配置環境變量。

      <access_key_id>需替換為您RAM用戶的AccessKey ID,<access_key_secret>替換為您RAM用戶的AccessKey Secret。如果后續需要進行更多權限相關的配置,具體操作請參見使用RAM Policy控制訪問權限

      export ALIBABA_CLOUD_ACCESS_KEY_ID=<access_key_id> 
      export ALIBABA_CLOUD_ACCESS_KEY_SECRET=<access_key_secret>
  • Windows系統配置方法

    新建環境變量文件,添加環境變量ALIBABA_CLOUD_ACCESS_KEY_IDALIBABA_CLOUD_ACCESS_KEY_SECRET,并寫入已準備好的AccessKey ID和AccessKey Secret。然后重啟Windows系統。本操作以Windows 10為例進行說明。

    1. 打開文件資源管理器,在此電腦上右鍵單擊屬性。

    2. 在右側導航欄,單擊高級系統配置

    3. 系統屬性對話框的高級頁簽下,單擊環境變量

    4. 環境變量對話框中,單擊新建(W)image.png

    5. 在彈出的新建系統變量對話框中,添加環境變量ALIBABA_CLOUD_ACCESS_KEY_IDALIBABA_CLOUD_ACCESS_KEY_SECRET,并寫入已準備好的AccessKey ID和AccessKey Secret。

    6. 重啟Windows系統,使配置生效。
