PHP Класс Aws\Credentials\CredentialProvider


use Aws\Credentials\CredentialProvider;
$provider = CredentialProvider::defaultProvider();
Returns a CredentialsInterface or throws.
$creds = $provider()->wait();

Credential providers can be composed to create credentials using conditional logic that can create different credentials in different environments. You can compose multiple providers into a single provider using {@see \Aws\Credentials\CredentialProvider::chain}. This function accepts providers as variadic arguments and returns a new function that will invoke each provider until a successful set of credentials is returned.


First try an INI file at this location.
$a = CredentialProvider::ini(null, '/path/to/file.ini');
Then try an INI file at this location.
$b = CredentialProvider::ini(null, '/path/to/other-file.ini');
Then try loading from environment variables.
$c = CredentialProvider::env();
Combine the three providers together.
$composed = CredentialProvider::chain($a, $b, $c);
Returns a promise that is fulfilled with credentials or throws.
$promise = $composed();
Wait on the credentials to resolve.
$creds = $promise->wait();

Открытые методы

Метод	Описание
cache ( callable $provider, Aws\CacheInterface $cache, string \| null $cacheKey = null ) : callable	Wraps a credential provider and saves provided credentials in an instance of Aws\CacheInterface. Forwards calls when no credentials found in cache and updates cache with the results.
chain ( ) : callable	Creates an aggregate credentials provider that invokes the provided variadic providers one after the other until a provider returns credentials.
defaultProvider ( array $config = [] ) : callable	Create a default credential provider that first checks for environment variables, then checks for the "default" profile in ~/.aws/credentials, then tries to make GET Request to fetch credentials if Ecs environment variable is presented, and finally checks for EC2 instance profile credentials.
ecsCredentials ( array $config = [] ) : EcsCredentialProvider	Credential provider that creates credentials using ecs credentials by a GET request, whose uri is specified by environment variable
env ( ) : callable	Provider that creates credentials from environment variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_SESSION_TOKEN.
fromCredentials ( Aws\Credentials\CredentialsInterface $creds ) : callable	Create a credential provider function from a set of static credentials.
ini ( string \| null $profile = null, string \| null $filename = null ) : callable	Credentials provider that creates credentials using an ini file stored in the current user's home directory.
instanceProfile ( array $config = [] ) : Aws\Credentials\InstanceProfileProvider	Credential provider that creates credentials using instance profile credentials.
memoize ( callable $provider ) : callable	Wraps a credential provider and caches previously provided credentials.
