Create a resource service client by name.
:type service_name: string
:param service_name: The name of a service, e.g. 's3' or 'ec2'. You
can get a list of available services via
:py:meth:`get_available_resources`.
:type region_name: string
:param region_name: The name of the region associated with the client.
A client is associated with a single region.
:type api_version: string
:param api_version: The API version to use. By default, botocore will
use the latest API version when creating a client. You only need
to specify this parameter if you want to use a previous API version
of the client.
:type use_ssl: boolean
:param use_ssl: Whether or not to use SSL. By default, SSL is used.
Note that not all services support non-ssl connections.
:type verify: boolean/string
:param verify: Whether or not to verify SSL certificates. By default
SSL certificates are verified. You can provide the following
values:
* False - do not validate SSL certificates. SSL will still be
used (unless use_ssl is False), but SSL certificates
will not be verified.
* path/to/cert/bundle.pem - A filename of the CA cert bundle to
uses. You can specify this argument if you want to use a
different CA cert bundle than the one used by botocore.
:type endpoint_url: string
:param endpoint_url: The complete URL to use for the constructed
client. Normally, botocore will automatically construct the
appropriate URL to use when communicating with a service. You
can specify a complete URL (including the "http/https" scheme)
to override this behavior. If this value is provided,
then ``use_ssl`` is ignored.
:type aws_access_key_id: string
:param aws_access_key_id: The access key to use when creating
the client. This is entirely optional, and if not provided,
the credentials configured for the session will automatically
be used. You only need to provide this argument if you want
to override the credentials used for this specific client.
:type aws_secret_access_key: string
:param aws_secret_access_key: The secret key to use when creating
the client. Same semantics as aws_access_key_id above.
:type aws_session_token: string
:param aws_session_token: The session token to use when creating
the client. Same semantics as aws_access_key_id above.
:type config: botocore.client.Config
:param config: Advanced client configuration options. If region_name
is specified in the client config, its value will take precedence
over environment variables and configuration values, but not over
a region_name value passed explicitly to the method. If
user_agent_extra is specified in the client config, it overrides
the default user_agent_extra provided by the resource API. See
`botocore config documentation
<https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html>`_
for more details.
