通过环境变量配置访问凭证（AKSK）

1. 说明：

   1. 阿里云账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维，请登录RAM控制台创建RAM用户。

   2. 强烈建议不要把AccessKey和AccessKeySecret保存到代码里，会存在密钥泄漏风险，在此提供通过配置环境变量的方式来保存和访问aksk

2. Linux和macOS系统配置方法

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

   其中<access_key_id>替换为已准备好的AccessKey ID，<access_key_secret>替换为AccessKey Secret，AccessKey ID和AccessKey Secret的获取方式见步骤二：获取账号的AccessKey

3. Windows系统配置方法

   1. 新建环境变量文件，添加环境变量NLP_AK_ENV和NLP_SK_ENV，并写入已准备好的AccessKey ID和AccessKey Secret。

   2. 重启Windows系统。

Java代码示例

/**
 * 阿里云账号AccessKey拥有所有API的访问权限，风险很高。强烈建议您创建并使用RAM用户进行API访问或日常运维，请登录RAM控制台创建RAM用户。
 * 此处以把AccessKey和AccessKeySecret保存在环境变量为例说明。您也可以根据业务需要，保存到配置文件里。
 * 强烈建议不要把AccessKey和AccessKeySecret保存到代码里，会存在密钥泄漏风险
