This class fires two events scoped to a service and operation name: * choose-signer: Allows overriding the auth signer name. * before-sign: Allows mutating the request before signing. Together these events allow for customization of the request signing pipeline, including overrides, request path manipulation, and disabling signing per operation. :type service_id: botocore.model.ServiceId :param service_id: The service id for the service, e.g. ``S3`` :type region_name: string :param region_name: Name of the service region, e.g. ``us-east-1`` :type signing_name: string :param signing_name: Service signing name. This is usually the same as the service name, but can differ. E.g. ``emr`` vs. ``elasticmapreduce``. :type signature_version: string :param signature_version: Signature name like ``v4``. :type credentials: :py:class:`~botocore.credentials.Credentials` :param credentials: User credentials with which to sign requests. :type event_emitter: :py:class:`~botocore.hooks.BaseEventHooks` :param event_emitter: Extension mechanism to fire events.

Note that bucket related conditions should not be included in the ``conditions`` parameter. :type Key: string :param Key: Key name, optionally add ${filename} to the end to attach the submitted filename. Note that key related conditions and fields are filled out for you and should not be included in the ``Fields`` or ``Conditions`` parameter. :type Fields: dict :param Fields: A dictionary of prefilled form fields to build on top of. Elements that may be included are acl, Cache-Control, Content-Type, Content-Disposition, Content-Encoding, Expires, success_action_redirect, redirect, success_action_status, and x-amz-meta-. Note that if a particular element is included in the fields dictionary it will not be automatically added to the conditions list. You must specify a condition for the element as well. :type Conditions: list :param Conditions: A list of conditions to include in the policy. Each element can be either a list or a structure. For example: .. code:: python [ {"acl": "public-read"}, ["content-length-range", 2, 5], ["starts-with", "$success_action_redirect", ""] ] Conditions that are included may pertain to acl, content-length-range, Cache-Control, Content-Type, Content-Disposition, Content-Encoding, Expires, success_action_redirect, redirect, success_action_status, and/or x-amz-meta-. Note that if you include a condition, you must specify a valid value in the fields dictionary as well. A value will not be added automatically to the fields dictionary based on the conditions. :type ExpiresIn: int :param ExpiresIn: The number of seconds the presigned post is valid for. :rtype: dict :returns: A dictionary with two elements: ``url`` and ``fields``. Url is the url to post to. Fields is a dictionary filled with the form fields and respective values to use when submitting the post. For example: .. code:: python { 'url': 'https://amzn-s3-demo-bucket.s3.amazonaws.com', 'fields': { 'acl': 'public-read', 'key': 'mykey', 'signature': 'mysignature', 'policy': 'mybase64 encoded policy' } } NTr CreateBucketrrrRrFrbucketz ${filename}z starts-withz$keyrh)rmrrrH)copyrrrrrrrr r rCr r rrTrr)rrKeyFields ConditionsrrrhrrrHr>post_presignerrrrrrrrms r$rrGsPF C FJJ ~ #:4@G %T%9%9:Nii--==nMO  " "f%'#F $$VZZ"%=>M &&#00 '  00'!"# 1Lx() ||M"=K]9K8K2LMN5#,'F5M  1 1! 2 r&c<|jjdk7ry|jjj}|r`|j ddry|j ddk(r$|jjj dk(ry|j ddk(ryy ) NawsFuse_dualstack_endpointus_east_1_regional_endpointregionalz us-east-1addressing_stylevirtualT)r partitionconfigs3rCr)client s3_configs r$rrs {{% ""%%I ==15 9 MM7 8J F ""..+= ==+ , 9 r&r)Nr)NrpN)NNrp)%rrrrrA botocore.authbotocore.awsrequestrrbotocore.compatrrbotocore.exceptionsrrr r botocore.tokensr botocore.utilsr r rrrxrrrrrrrrrnrrrr<r&r$r0s K= ,IIX C C LH3(n470(h,/,,/*W6W6tH AEL^J @DL^r&
