Quick Start Examples

All examples use DefaultAzureCredential for authentication, which is recommended for local development only. In production, use ManagedIdentityCredential — see auth-best-practices.md. Rust uses DeveloperToolsCredential as it doesn't have a DefaultAzureCredential equivalent.

Python - Upload Blob:

from azure.identity import DefaultAzureCredential
from azure.storage.blob import BlobServiceClient

service = BlobServiceClient(account_url="https://ACCOUNT.blob.core.windows.net/", credential=DefaultAzureCredential())
container = service.get_container_client("my-container")
blob = container.get_blob_client("my-blob.txt")
blob.upload_blob(b"Hello, Azure Storage!", overwrite=True)

JavaScript - Upload Blob:

import { DefaultAzureCredential } from "@azure/identity";
import { BlobServiceClient } from "@azure/storage-blob";

const client = new BlobServiceClient("https://ACCOUNT.blob.core.windows.net/", new DefaultAzureCredential());
const container = client.getContainerClient("my-container");
const blob = container.getBlockBlobClient("my-blob.txt");
await blob.uploadData(Buffer.from("Hello, Azure Storage!"));

C# - Upload Blob:

using Azure.Identity;
using Azure.Storage.Blobs;

var client = new BlobServiceClient(new Uri("https://ACCOUNT.blob.core.windows.net/"), new DefaultAzureCredential());
var container = client.GetBlobContainerClient("my-container");
var blob = container.GetBlobClient("my-blob.txt");
await blob.UploadAsync(BinaryData.FromString("Hello, Azure Storage!"), overwrite: true);

Java - Upload Blob:

import com.azure.identity.*;
import com.azure.storage.blob.*;
import com.azure.core.util.BinaryData;

BlobServiceClient client = new BlobServiceClientBuilder()
    .endpoint("https://ACCOUNT.blob.core.windows.net/")
    .credential(new DefaultAzureCredentialBuilder().build())
    .buildClient();
BlobContainerClient container = client.getBlobContainerClient("my-container");
BlobClient blob = container.getBlobClient("my-blob.txt");
blob.upload(BinaryData.fromString("Hello, Azure Storage!"), true);

Go - Upload Blob:

package main

import (
    "context"

    "github.com/Azure/azure-sdk-for-go/sdk/azidentity"
    "github.com/Azure/azure-sdk-for-go/sdk/storage/azblob"
)

func main() {
    cred, _ := azidentity.NewDefaultAzureCredential(nil)
    client, _ := azblob.NewClient("https://ACCOUNT.blob.core.windows.net/", cred, nil)

    data := []byte("Hello, Azure Storage!")
    _, _ = client.UploadBuffer(context.Background(), "my-container", "my-blob.txt", data, nil)
}

Rust - Upload Blob:

use azure_identity::DeveloperToolsCredential;
use azure_storage_blob::{BlobClient, BlobClientOptions};

let credential = DeveloperToolsCredential::new(None)?;
let blob_client = BlobClient::new(
    "https://ACCOUNT.blob.core.windows.net/",
    "my-container",
    "my-blob.txt",
    Some(credential),
    Some(BlobClientOptions::default()),
)?;
let data = b"Hello, Azure Storage!";
blob_client.upload(None, data.to_vec().into()).await?;
