配置环境变量
配置环境变量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET。
重要
阿里云账号AccessKey拥有所有API的访问权限，建议您使用RAM用户进行API访问或日常运维，具体操作，请参见创建RAM用户。
创建AccessKey ID和AccessKey Secret，请参考创建AccessKey。
如果您使用的是RAM用户的AccessKey，请确保主账号已授权AliyunServiceRoleForOpenSearch服务关联角色，请参考OpenSearch-行业算法版服务关联角色，相关文档参考访问鉴权规则。
请不要将AccessKey ID和AccessKey Secret保存到工程代码里，否则可能导致AccessKey泄露，威胁您账号下所有资源的安全。
Linux和macOS系统配置方法：
执行以下命令，其中，
<access_key_id>需替换为您RAM用户的AccessKey ID，<access_key_secret>替换为您RAM用户的AccessKey Secret。export ALIBABA_CLOUD_ACCESS_KEY_ID=<access_key_id> export ALIBABA_CLOUD_ACCESS_KEY_SECRET=<access_key_secret>Windows系统配置方法
新建环境变量文件，添加环境变量ALIBABA_CLOUD_ACCESS_KEY_ID和ALIBABA_CLOUD_ACCESS_KEY_SECRET，并写入已准备好的AccessKey ID和AccessKey Secret。
重启Windows系统生效。
