Configure environment variables

In Alibaba Cloud SDK code, you can create a default access credential by defining ALIBABA_CLOUD_ACCESS_KEY_ID and ALIBABA_CLOUD_ACCESS_KEY_SECRET environment variables. When you call API operations of Alibaba Cloud services, the system directly accesses the credential, reads your AccessKey pair, and then automatically completes authentication. Before you use the SDK sample code, you must configure environment variables. For more information, see Configure credentials.
