ColdFusion and Azure Blob

Introduction

Blob or Binary Large OBject include images, text files, videos, or audio. Azure BLOB storage is a persistent data storage in cloud, which you can utilize to store BLOB data.

ColdFusion and Azure Blob

ColdFusion (2018 release) included support for AWS S3 storage service. In ColdFusion (2021 release), we have extended it to provide multi-cloud storage with Azure Blob, so that you can use different storage services for storing and retrieve data based on your requirement.

In ColdFusion, you can use the following operations for Azure storage service.

  • Perform different operations, for example, create, update, delete, or list in a container.
  • Upload and download items from the blob.
  • Apply policies in a container.
  • Copy a blob from one container to another container in the same account.
  • Share permission for container or blob in different user using shared access signature.
Nota:

On Weblogic 14.1.1.0.0, an Null Pointer Exception occurs when using Azure Blob as storage. For the workaround, see the work-around.

Get started

Install azureblob package

Adobe ColdFusion (2021 release) is modularized, if you are only using the ZIP installer. By default, the package for Azure Blob is not installed. The first step is to install the Blob package in ColdFusion.

Note: If you are using the GUI installer, the packages are pre-installed.

The package for Blob is called azureblob.

To install the package azureblob, use the Package Manager page in the ColdFusion Administrator, or follow the steps below:

  1. Navigate to <CF_HOME>/cfusion/bin.

  2. Enter the command:

    • Windows: cfpm.bat
    • Linux: cfpm.sh
  3. Enter the command, install azureblob.

    Wait for the Azure Blob package to get installed.

For more information, see ColdFusion Package Manager.

Add cloud service credentials and configuration

In ColdFusion (2021 release), there is a method getCloudService() that gives you a handle to create objects for accessing various cloud services.

The syntax of the service handle is as follows:

service=getCloudService(cloudCred,cloudConfig), where:

  • cloudCred: Defines the credentials for the cloud service. It could either be a struct or a string (also known as credential alias).
  • cloudConfig: Defines the cloud service configuration details. It could either be a struct or a string (also known as config alias).

After you've acquired the Azure credentials, you must declare these credentials in one of the following ways. Only then you can use these credentials to create a Blob object, after which you can use the object to make calls to the various Azure Blob methods.

ColdFusion Administrator

Set credentials

In the ColdFusion Administrator, click Data & Services > Cloud Credentials

An alias is a named representation of a cloud service and its configuration details. You can set the config alias through ColdFusion Administrator.

Add cloud credentials
Add cloud credentials

A connection string includes the authorization information required for your application to access data in an Azure Storage account.

For more information, see Configure Azure Storage connection strings.

After entering the details, click Add Credential.

Set configuration options

In the ColdFusion Administrator, click Data & Services > Cloud Configuration

Enter the following details, like configuration Alias, Vendor, and the name of the service.

Add cloud configuration options
Add cloud configuration options

After adding the configuration options, you may need to add a few more options. You can do so in the next screen. The following are a few options that you may need to add:

  • Concurrent Request Count
  • Single block size in bytes
  • Maximum Execution time (ms)
  • Retry policy type
  • Enable logging

For more information, see Cloud configuration options.

CREATE THE AZURE BLOB SERVICE OBJECT

Once you've created the aliases for Blob credential and configuration options, you can create the object by using the getCloudService API, and include the following in your CFM. 

blobObject= getCloudService("blobCred", "blobConf")

Application.cfc

You can specify the Blob credentials and configuration options in Application.cfc. For example,

omponent { 
    this.name ="AzureblobTest" 
    this.serialization.preservecaseforstructkey=true 
    this.enableNullSupport=true 
    void function onApplicationStart(){ 
        application.blobCred = { 
            "vendorName" : "AZURE", 
            "connectionString" : "xxxxxxxxxxx" 
        } 
 
        application.blobConf = { 
            "serviceName" : "AZURE_BLOB" 
        } 
 } 
 
}

CREATE THE AZURE BLOB SERVICE OBJECT

blobObject = getCloudService(application.blobCred, application.blobConf) 

On CFM page

On a CFM page, you can specify the Blob credentials and configuration options in one of the four methods, specified below:

Credential alias and configuration alias

After you've created the aliases for Azure Blob credential and configuration options, you can use these aliases in the getCloudService handle as shown below:

<cfscript> 
  // define the credential and the configuration aliases in the ColdFusion Admin 
  blobObject=getCloudService("blobCred","blobConf") 
  // code below. 
  ........... 
</cfscript>

Credential Alias and Struct for configuration options

<cfscript> 
    blobCred = { 
        "vendorName" : "AZURE", 
        "connectionString" : "xxxxxx" 
    } 
    blobConf = { 
        "serviceName" : "AZURE_BLOB", 
        "options" : { 
            "absorbConditionalErrorsOnRetry" : true/false,

Create a container

A container serves as a default container for your storage account. A storage account may have one container container. A blob stored in the container container may be addressed without referencing the container container name. For more information, see Azure Blob container.

Use the method container to create the container container. The method accepts two parameters:

  • Name of the container (required)
  • Public access type (optional): The parameter publicAccessType defines the level at which the access will be granted. This parameter can accept one of the four values:
    • BLOB: Specifies blob-level public access. Clients can read the content and metadata of blobs within this container but cannot read container metadata or list the blobs within the container.
    • CONTAINER: Specifies container-level public access. Clients can read blob content and metadata and container metadata and can list the blobs within the container.
    • OFF: Specifies no public access. Only the account owner can access resources in this container.

Create a snapshot

A blob snapshot is a read-only version of a blob that's taken at a single point in time. After a snapshot has been created, it can be read, copied, or deleted, but not modified. Snapshots provide a way to back up a blob as it appears at a moment in time.

A blob may have any number of snapshots. Snapshots persist until they're explicitly deleted. A snapshot can't outlive its source blob. You can enumerate the snapshots associated with your blob to track your current snapshots.

For more information, see Snapshots in Azure Blob.

Syntax

createSnapshot(parameterStruct)

Parameters

Parameter

Description

Required

blobName

The name of the blob whose snapshot you want to create.

Yes

keyName

The key associated with the blob.

Yes

Example

<cfscript> 
  storageService = getCloudService(application.blobCred, application.blobConf) 
  // create container 
  container = storageService.container("con001",true) 
  src = "#ExpandPath('./')#file.txt" 
  //writedump(src) 
  blobname = "Version-1" 
  // upload a file into the blob 
  uploadRequest = { 
    "srcFile" : src, 
    "blobName" : blobname 
  } 
  uploadResponse = container.uploadFile(uploadRequest) 
  //writeDump(uploadResponse) 
  // Create snapshot 
  // Create snapshot struct 
  versionRequest = { 
        "blobName" : "Version-1" 
      } 
  snapshot1 = container.Createsnapshot(versionRequest); 
  snapshot2 = container.Createsnapshot(versionRequest); 
  writeDump(snapshot1) 
  writeDump(snapshot2) 
</cfscript> 

Copy container in different account

Copy the blob in different account by using storage classes.

Example

<cfscript>  
  storageService1 = getCloudService(application.blobCred, application.blobConf) 
  rootList = storageService1.listAll() 
   
  for (i=1;i LTE ArrayLen(rootList);i=i+1) 
   { 
   if( (i GT 0 ) and (rootList[i].name Neq "rootpoc") ){ 
    storageService1.delete(rootList[i].name)} 
   } 
  sleep(35000) 
  rootobject = storageService1.container("#object1#",true); 
  rootList = storageService1.listAll() 
  FileWrite("#Dirpath#uploadfile.txt","this test copy with access condition and storage classes"); 
    src = "uploadfile.txt" 
    blobName = "A/B/key1" 
        uploadRequest = { 
            "srcFile" : src, 
            "blobName" : blobName 
        } 
    uploadResponse = rootobject.uploadFile(uploadRequest); 
 rootList = rootobject.listAll() 
 
 copyRequest = { 
        "source" : "root-object1/A/B/key1", 
        "storageClass" : "HOT", 
        "blobName" : "C/D/Key2" 
    } 
 copyResponse = rootobject.copy(copyRequest); 
 rootList = rootobject.listAll() 
 for (i=1;i LTE ArrayLen(rootList.response);i=i+1) 
 { 
  if(rootList.response[i].blobName eq "C/D/Key2"){ 
   writeoutput(rootList.response[i].properties.standardBlobTier & " ")}

Client-side encryption

In ColdFusion, you can use an RSA encryption key while uploading a blob. While downloading the same blob, you must provide the same RSA encryption key with password.

All data that is stored in Azure storage is automatically encrypted before uploading and decrypted during retrieval. Encryption and decryption are completely transparent to the user. All data is encrypted using 256-bit AES encryption. With encryption enabled by default, you need not make any changes to their applications.

getKeyPairfromkeystore

Import a key pair from a key store that is in your computer.

A JKS or a keystore is an encrypted security file that is used to store a set of cryptographic keys or certificates in the binary format, and it requires a password to be opened.

Syntax

getKeyPairfromkeystore(parameterStruct)

Parameters

Parameter

Description

keystore

Location of the keystore or jks file.

keystorePassword

Password of the jks file.

keypairPassword

Password of RSA keypair.

keystoreAlias

Alias name of the jks keystore.

keyStoreType

Jks or pkcs12.

Example- p12 key

<cfscript> 
    storageService = getCloudService(application.blobCred, application.blobConf) 
    keyPair2 = getKeyPairfromkeystore({  
        "keystore": ExpandPath("blobkey.p12"),  
        "keystorePassword": "changeit"  
    }) 
    // create a root
