public final class BlobClientBuilder extends Object
This class provides a fluent builder API to help aid the configuration and instantiation ofBlobClients
andBlobAsyncClients
, callbuildClient
andbuildAsyncClient
respectively to construct an instance of the desired client.The following information must be provided on this builder:
- the endpoint through
.endpoint()
, including the container name and blob name, in the format ofhttps://{accountName}.blob.core.windows.net/{containerName}/{blobName}
. - the credential through
.credential()
or.connectionString()

Method Detail
-
buildClient
public BlobClient buildClient()
Creates aBlobClient
based on options set in the builder. BlobClients are used to perform generic blob methods such asdownload
andget properties
, use this when the blob type is unknown.Code Samples
BlobClient client = new BlobClientBuilder() .connectionString(connectionString) .buildClient();
- Returns:
- a
BlobClient
created from the configurations in this builder. - Throws:
NullPointerException
- Ifendpoint
orblobName
isnull
.IllegalStateException
- If multiple credentials have been specified.
-
buildAsyncClient
public BlobAsyncClient buildAsyncClient()
Creates aBlobAsyncClient
based on options set in the builder. BlobAsyncClients are used to perform generic blob methods such asdownload
andBlobAsyncClientBase.getProperties()
, use this when the blob type is unknown.Code Samples
BlobAsyncClient client = new BlobClientBuilder() .connectionString(connectionString) .buildAsyncClient();
- Returns:
- a
BlobAsyncClient
created from the configurations in this builder. - Throws:
NullPointerException
- Ifendpoint
orblobName
isnull
.IllegalStateException
- If multiple credentials have been specified.
-
customerProvidedKey
public BlobClientBuilder customerProvidedKey(CustomerProvidedKey customerProvidedKey)
Sets thecustomer provided key
that is used to encrypt blob contents on the server.- Parameters:
customerProvidedKey
-CustomerProvidedKey
- Returns:
- the updated BlobClientBuilder object
-
encryptionScope
public BlobClientBuilder encryptionScope(String encryptionScope)
Sets theencryption scope
that is used to encrypt blob contents on the server.- Parameters:
encryptionScope
- Encryption scope containing the encryption key information.- Returns:
- the updated BlobClientBuilder object
-
credential
public BlobClientBuilder credential(StorageSharedKeyCredential credential)
Sets theStorageSharedKeyCredential
used to authorize requests sent to the service.- Parameters:
credential
-StorageSharedKeyCredential
.- Returns:
- the updated BlobClientBuilder
- Throws:
NullPointerException
- Ifcredential
isnull
.
-
credential
public BlobClientBuilder credential(com.azure.core.credential.TokenCredential credential)
Sets theTokenCredential
used to authorize requests sent to the service.- Parameters:
credential
-TokenCredential
.- Returns:
- the updated BlobClientBuilder
- Throws:
NullPointerException
- Ifcredential
isnull
.
-
sasToken
public BlobClientBuilder sasToken(String sasToken)
Sets the SAS token used to authorize requests sent to the service.- Parameters:
sasToken
- The SAS token to use for authenticating requests. This string should only be the query parameters (with or without a leading '?') and not a full url.- Returns:
- the updated BlobClientBuilder
- Throws:
NullPointerException
- IfsasToken
isnull
.
-
credential
public BlobClientBuilder credential(com.azure.core.credential.AzureSasCredential credential)
Sets theAzureSasCredential
used to authorize requests sent to the service.- Parameters:
credential
-AzureSasCredential
used to authorize requests sent to the service.- Returns:
- the updated BlobClientBuilder
- Throws:
NullPointerException
- Ifcredential
isnull
.
-
setAnonymousAccess
public BlobClientBuilder setAnonymousAccess()
Clears the credential used to authorize the request.This is for blobs that are publicly accessible.
- Returns:
- the updated BlobClientBuilder
-
connectionString
public BlobClientBuilder connectionString(String connectionString)
Sets the connection string to connect to the service.- Parameters:
connectionString
- Connection string of the storage account.- Returns:
- the updated BlobClientBuilder
- Throws:
IllegalArgumentException
- IfconnectionString
in invalid.
-
endpoint
public BlobClientBuilder endpoint(String endpoint)
Sets the service endpoint, additionally parses it for information (SAS token, container name, blob name)If the blob name contains special characters, pass in the url encoded version of the blob name.
If the endpoint is to a blob in the root container, this method will fail as it will interpret the blob name as the container name. With only one path element, it is impossible to distinguish between a container name and a blob in the root container, so it is assumed to be the container name as this is much more common. When working with blobs in the root container, it is best to set the endpoint to the account url and specify the blob name separately using the
blobName
method.- Parameters:
endpoint
- URL of the service- Returns:
- the updated BlobClientBuilder object
- Throws:
IllegalArgumentException
- Ifendpoint
isnull
or is a malformed URL.
-
containerName
public BlobClientBuilder containerName(String containerName)
Sets the name of the container that contains the blob.- Parameters:
containerName
- Name of the container. If the valuenull
or empty the root container,$root
, will be used.- Returns:
- the updated BlobClientBuilder object
-
blobName
public BlobClientBuilder blobName(String blobName)
Sets the name of the blob.- Parameters:
blobName
- Name of the blob. If the blob name contains special characters, pass in the url encoded version of the blob name.- Returns:

isnull
-

Sets the snapshot identifier of the blob.- Parameters:
snapshot
- Snapshot identifier for the blob.- Returns:
- the updated BlobClientBuilder object

-
serviceVersion
public BlobClientBuilder serviceVersion(BlobServiceVersion version)
Sets theBlobServiceVersion
that is used when making API requests.If a service version is not provided, the service version that will be used will be the latest known service version based on the version of the client library being used. If no service version is specified, updating to a newer version of the client library will have the result of potentially moving to a newer service version.
Targeting a specific service version may also mean that the service will return an error for newer APIs.
- Parameters:
version
-BlobServiceVersion
of the service to be used when making requests.- Returns:
