通過環境變量配置訪問憑證（AKSK）

1. 說明：

   1. 阿里云賬號AccessKey擁有所有API的訪問權限，風險很高。強烈建議您創建并使用RAM用戶進行API訪問或日常運維，請登錄RAM控制臺創建RAM用戶。

   2. 強烈建議不要把AccessKey和AccessKeySecret保存到代碼里，會存在密鑰泄漏風險，在此提供通過配置環境變量的方式來保存和訪問aksk

2. Linux和macOS系統配置方法

   export NLP_AK_ENV=<access_key_id>
   export NLP_SK_ENV=<access_key_secret>

   其中<access_key_id>替換為已準備好的AccessKey ID，<access_key_secret>替換為AccessKey Secret，AccessKey ID和AccessKey Secret的獲取方式見步驟二：獲取賬號的AccessKey

3. Windows系統配置方法

   1. 新建環境變量文件，添加環境變量NLP_AK_ENV和NLP_SK_ENV，并寫入已準備好的AccessKey ID和AccessKey Secret。

   2. 重啟Windows系統。
