ExecutionContext.getCredentialsProvider介绍

[英]Returns the credentials provider used for fetching the credentials. The credentials fetched is used for signing the request. If there is no credential provider, then the runtime will not attempt to sign (or resign on retries) requests.
[中]返回用于获取凭据的凭据提供程序。获取的凭据用于对请求进行签名。如果没有凭据提供程序，则运行时将不会尝试签署（或重试时退出）请求。
