In order to be able to use qingstor-sdk, you need to apply for an API key pair in our console first, which contains an access_key_id and a secret_access_key.
access_key_id will be included as a parameter to be sent in each request; secret_access_key' is responsible for generating the signature of the request, secret_access_key' needs to be kept safely, please do not share it with people you do not trust.
