Please see the `Signed URLs documentation <https://cloud.google.com/storage/docs/access-control/signed-urls>`_ for background about signed URLs. Multiple gs:// URLs may be provided and may contain wildcards. A signed URL will be produced for each provided URL, authorized for the specified HTTP method and valid for the given duration. NOTE: Unlike the gsutil ls command, the signurl command does not support operations on sub-directories. For example, unless you have an object named ``some-directory/`` stored inside the bucket ``some-bucket``, the following command returns an error: ``gsutil signurl <private-key-file> gs://some-bucket/some-directory/`` The signurl command uses the private key for a service account (the '<private-key-file>' argument) to generate the cryptographic signature for the generated URL. The private key file must be in PKCS12 or JSON format. If the private key is encrypted the signed URL command will prompt for the passphrase used to protect the private key file (default 'notasecret'). For more information regarding generating a private key for use with the signurl command please see the `Authentication documentation. <https://cloud.google.com/storage/docs/authentication#generating-a-private-key>`_ If you used `service account credentials <https://cloud.google.com/storage/docs/gsutil/addlhelp/CredentialTypesSupportingVariousUseCases#supported-credential-types_1>`_ for authentication, you can replace the <private-key-file> argument with the -u or --use-service-account option to use the system-managed private key directly. This avoids the need to store a private key file locally, but prior to using this flag you must `configure <https://cloud.google.com/sdk/gcloud/reference/auth/activate-service-account>`_ ``gcloud`` to use your service account credentials. <B>OPTIONS</B> -b <project> Allows you to specify a user project that will be billed for requests that use the signed URL. This is useful for generating presigned links for buckets that use requester pays. Note that it's not valid to specify both the ``-b`` and ``--use-service-account`` options together. -c Specifies the content type for which the signed URL is valid for. -d Specifies the duration that the signed URL should be valid for, default duration is 1 hour. Times may be specified with no suffix (default hours), or with s = seconds, m = minutes, h = hours, d = days. This option may be specified multiple times, in which case the duration the link remains valid is the sum of all the duration options. The max duration allowed is 7 days when ``private-key-file`` is used. The max duration allowed is 12 hours when -u option is used. This limitation exists because the system-managed key used to sign the URL may not remain valid after 12 hours. -m Specifies the HTTP method to be authorized for use with the signed URL, default is GET. You may also specify RESUMABLE to create a signed resumable upload start URL. When using a signed URL to start a resumable upload session, you will need to specify the 'x-goog-resumable:start' header in the request or else signature validation will fail. -p Specify the private key password instead of prompting. -r <region> Specifies the `region <https://cloud.google.com/storage/docs/locations>`_ in which the resources for which you are creating signed URLs are stored. Default value is 'auto' which will cause gsutil to fetch the region for the resource. When auto-detecting the region, the current gsutil user's credentials, not the credentials from the private-key-file, are used to fetch the bucket's metadata. This option must be specified and not 'auto' when generating a signed URL to create a bucket. -u Use service account credentials instead of a private key file to sign the URL. You can also use the ``--use-service-account`` option, which is equivalent to ``-u``. Note that both options have a maximum allowed duration of 12 hours for a valid link. <B>USAGE</B> Create a signed URL for downloading an object valid for 10 minutes: gsutil signurl -d 10m <private-key-file> gs://<bucket>/<object> Create a signed URL, valid for one hour, for uploading a plain text file via HTTP PUT: gsutil signurl -m PUT -d 1h -c text/plain <private-key-file> \ gs://<bucket>/<obj> To construct a signed URL that allows anyone in possession of the URL to PUT to the specified bucket for one day, creating an object of Content-Type image/jpg, run: gsutil signurl -m PUT -d 1d -c image/jpg <private-key-file> \ gs://<bucket>/<obj> To construct a signed URL that allows anyone in possession of the URL to POST a resumable upload to the specified bucket for one day, creating an object of Content-Type image/jpg, run: gsutil signurl -m RESUMABLE -d 1d -c image/jpg <private-key-file> \ gs://bucket/<obj> c C s t jtjd�jdd�S )z2Returns the current utc time as a datetime object.��tzN��tzinfo)r �nowr �utc�replace� r2 r2 �%/opt/gsutil/gslib/commands/signurl.py�_NowUTC� s r4 c C s� t �d| �}|std��|�d�\} }t| �} |�� }|dkrJt| d�}n:|dkr^t| d�}n&|dkrrt| d�}n|d kr�t| d �}|S ) z>Parses the given duration and returns an equivalent timedelta.z^(\d+)([dDhHmMsS])?$z Unable to parse duration string�h�dr& r) �m)�minutes�s��seconds)�re�matchr �groups�int�lowerr )�durationr= �modifier�retr2 r2 r3 �_DurationToTimeDelta� s rD c C s� t �ddd�}d|i}|dkr8d}d|d< | s8|�d � | rD| |d < |rf|j||||| || || d � }n|tjrrd }nd }t||||| || || | d� \}}t| t�r�t | ||�}n&t s�t t ��| � t |�t�� t�� �}t||||�}|S )a1 Construct a string to sign with the provided key.
