Let’s say you have an image and want to provide a downloadable link. The Azure SDK for Python contains libraries that build on top of the Azure REST API, allowing you to interact with REST API operations through familiar Python paradigms.There are basically two kinds of creating a downloadable link: To learn more about how to download blobs using the Azure Blob Storage client library for Python, see the following resources. # encoding param is necessary for readall() to return str, otherwise it returns bytesĭownloader = blob_client.download_blob(max_concurrency=1, encoding='UTF-8') In this example, the encoding parameter is necessary for readall() to return a string, otherwise it returns bytes: def download_blob_to_string(self, blob_service_client: BlobServiceClient, container_name): The following example downloads blob contents as text. # Process your data (anything can be done here - 'chunk' is a byte array)

# Read data in chunks to avoid loading all into memory at once In this example, StorageStreamDownloader.chunks returns an iterator, which allows you to read the blob content in chunks: def download_blob_chunks(self, blob_service_client: BlobServiceClient, container_name): The following example downloads a blob and iterates over chunks in the download stream.

Num_bytes = blob_client.download_blob().readinto(stream) # readinto() downloads the blob contents to a stream and returns the number of bytes read In this example, StorageStreamDownloader.read_into downloads the blob contents to a stream and returns the number of bytes read: def download_blob_to_stream(self, blob_service_client: BlobServiceClient, container_name): The following example downloads a blob to a stream.

Sample_blob.write(download_stream.readall()) With open(file=os.path.join('filepath', 'filename'), mode='wb') as sample_blob:ĭownload_stream = blob_client.download_blob() The following example downloads a blob to a file path: def download_blob_to_file(self, blob_service_client: BlobServiceClient, container_name):īlob_client = blob_service_client.get_blob_client(container=container_name, blob='sample-blob.txt') The download_blob method returns a StorageStreamDownloader object. You can download a blob by using the following method: This article shows how to download a blob using the Azure Storage client library for Python.
