Cloud Storage API
The Google Cloud Storage API is a tool that allows developers to interact with Google Cloud Storage using Python. It provides a comprehensive set of methods and functions to manage buckets and objects within the cloud storage environment.
Installation
You can install the Google Cloud Storage Python library by running the following command:
$ pip install google-cloud-storage
Retrieving a Bucket
To retrieve information about a specific bucket in Google Cloud Storage using the Python API, you can follow these steps:
from google.cloud import storage
# Create a client
client = storage.Client()
# Retrieve the bucket
bucket = client.get_bucket(bucket_name)
# Print bucket details
print("Bucket Name: {}".format(bucket.name))
print("Location: {}".format(bucket.location))
print("Storage Class: {}".format(bucket.storage_class))
Retrieving a List of Buckets
To obtain a list of all the buckets associated with your project, you can use the following code:
from google.cloud import storage
# Create a client
client = storage.Client()
# Retrieve the list of buckets
buckets = client.list_buckets()
# Print bucket names
for bucket in buckets:
print("Bucket Name: {}".format(bucket.name))
Creating a Bucket
To create a new bucket programmatically using the Google Cloud Storage API, you can use the following code:
from google.cloud import storage
# Create a client
client = storage.Client()
# Create the bucket
bucket = client.create_bucket(bucket_name, location=location, storage_class=storage_class)
print("Bucket {} created.".format(bucket.name))
Deleting a Bucket
To delete a bucket in Google Cloud Storage using the Python API, you can follow these steps:
from google.cloud import storage
# Create a client
client = storage.Client()
# Retrieve the bucket
bucket = client.get_bucket(bucket_name)
# Delete the bucket
bucket.delete()
print("Bucket {} deleted.".format(bucket.name))
Retrieving a List of Objects
To retrieve a list of objects within a Google Cloud Storage bucket using the Python API, you can use the following code:
from google.cloud import storage
# Create a client
client = storage.Client()
# Retrieve the bucket
bucket = client.get_bucket(bucket_name)
# List objects in the bucket
objects = bucket.list_blobs()
# Print object names
for obj in objects:
print("Object Name: {}".format(obj.name))
Downloading and Uploading Objects as Files
To download and upload objects as files in Google Cloud Storage using the Python API, you can use the following code:
from google.cloud import storage
# Create a client
client = storage.Client()
# Retrieve the bucket
bucket = client.get_bucket(bucket_name)
# Download an object as a file
blob = bucket.blob(object_name)
blob.download_to_filename(local_file_path)
print("Object downloaded and saved as file: {}".format(local_file_path))
# Upload a file as an object
blob = bucket.blob(new_object_name)
blob.upload_from_filename(local_file_path)
print("File uploaded as object: {}".format(new_object_name))
Downloading Objects as File Objects from Resources
To download objects from Google Cloud Storage and retrieve them as file objects in Python, you can use the following code:
from google.cloud import storage
# Create a client
client = storage.Client()
# Retrieve the bucket
bucket = client.get_bucket(bucket_name)
# Retrieve the object
blob = bucket.get_blob(object_name)
# Download the object as a file object
file_object = blob.download_as_file()
# Read the contents from the file object
content = file_object.read()
print("Object Content: {}".format(content))
Downloading Objects as File Objects from URLs
To download objects from Google Cloud Storage using a URL and retrieve them as file objects in Python, you can use the following code:
import requests
# Specify the URL of the object
object_url = "https://storage.googleapis.com/{}/{}".format(bucket_name, object_name)
# Download the object and retrieve it as a file object
response = requests.get(object_url)
file_object = response.content
# Read the contents from the file object
content = file_object.read()
print("Object Content: {}".format(content))
Deleting an Object
To delete an object from a Google Cloud Storage bucket using the Python API, you can use the following code:
from google.cloud import storage
# Create a client
client = storage.Client()
# Retrieve the bucket
bucket = client.get_bucket(bucket_name)
# Delete the object
blob = bucket.blob(object_name)
blob.delete()
print("Object {} deleted.".format(object_name))
