Download file from AZURE BLOB CONTAINER using SAS URI in PYTHON

Question

I have Azure container where i keep some files. I need to access them using python code I did same thing in JAVA but i am unable to replicate it in Python

//This is java code for same.

CloudBlobContainer Con = new CloudBlobContainer("Some SAS URI");

CloudBlockBlob blob1 = Con.getBlockBlobReference(fileName);

blob1.downloadToFile(filePath+fileName+userName);

What kind of SAS URI do you have? Is it for the blob container or blob? Please edit your question and include the SAS URI (you can obfuscate the account name and sig portion of the SAS URI). — Gaurav Mantri

There is no equivalent method in python, you can take a look at the Container class of python

You should always use BlockBlobService with sas token(if you have a sas uri, you can get sas token from it) or account key, like below if you use sas token:

from azure.storage.blob import BlockBlobService

blobservice = BlockBlobService("storage_account",sas_token="?sv=2018-03-28&ss=bfqt&srt=sco&sp=rwdlacup&se=2019-04-24T10:01:58Z&st=2019-04-23T02:01:58Z&spr=https&sig=xxxxxxxxx")
blobservice.get_blob_to_path("container_name","blob_name","local_file_path")

Yes it works fine thanks I didn't knew that BlockBlobService method has sas_token parameter also.

If you are using newer version that does not have BlockBlobService, you can use BlobClient:

from azure.storage.blob import BlobClient

blob_client = BlobClient.from_blob_url(sas_url)
with open(file=blob_client.blob_name, mode="wb") as blob_file:
    download_stream = blob_client.download_blob()
    blob_file.write(download_stream.readall())
