Method: googleapis.storage.v1.objects.get

Note that Workflows supports a number of library functions for data type and format conversions. For example, if you specify alt=media as the response data format, you can use the text.decode function to decode data in bytes to string.

Retrieves an object or its metadata.

Arguments

Parameters
bucket

string

Required. Name of the bucket in which the object resides.

object

string

Required. Name of the object. For information about how to URL encode object names to be path safe, see Encoding URI Path Parts.

generation

string (int64 format)

If present, selects a specific revision of this object (as opposed to the latest version, the default).

ifGenerationMatch

string (int64 format)

Makes the operation conditional on whether the object's current generation matches the given value. Setting to 0 makes the operation succeed only if there are no live versions of the object.

ifGenerationNotMatch

string (int64 format)

Makes the operation conditional on whether the object's current generation does not match the given value. If no live object exists, the precondition fails. Setting to 0 makes the operation succeed only if there is a live version of the object.

ifMetagenerationMatch

string (int64 format)

Makes the operation conditional on whether the object's current metageneration matches the given value.

ifMetagenerationNotMatch

string (int64 format)

Makes the operation conditional on whether the object's current metageneration does not match the given value.
