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。
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
1. 在IntelliJ IDEA中打开终端Terminal。
2. 执行以下命令，配置环境变量。
  <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。如果后续需要进行更多权限相关的配置，具体操作请参见使用RAM Policy控制访问权限。
```
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。然后重启Windows系统。本操作以Windows 10为例进行说明。
1. 打开文件资源管理器，在此电脑上右键单击属性。
2. 在右侧导航栏，单击高级系统配置。
3. 在系统属性对话框的高级页签下，单击环境变量。
4. 在环境变量对话框中，单击新建(W)。
5. 在弹出的新建系统变量对话框中，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。
6. 重启Windows系统，使配置生效。
