Azure PHP SDK: get the asset by asset name - php

Question

Is it possible to get the asset details using asset name with Azure PHP sdk. I can get all the asset list, but it's loading first 1000 assets only.
getAssetList();
I can get single asset details using asset id.
getAsset($asset);
But in my case, I don't have asset id with me. I just have asset name alone. Now how do I get the asset details using this?
EDIT:
I got some help from Azure support saying that, we can use $skip parameter for pagination. I got code snippet in c#
for (int i = 0; i < _context.Assets.Count(); i += 1000 )
{
var assets = _context.Assets.Skip(i);
foreach (IAsset objIAsset in assets)
{
Console.WriteLine(objIAsset.Name.ToString());
}
}
How can I use this param in PHP SDK.

Answer 1

It seem that Azure SDK for PHP don't support skip method. However, I used the fiddler to monitor C# skip method and got the URL like this:
https://***-hs.cloudapp.net/api/Assets()?$skip=1000
So I think we can bulid up the request path like above in our PHP project and we can modify the getAssetList method in "MediaServicesRestProxy" file.
I add a function named "getAssetListBySkip($number)" into "MediaServicesRestProxy" class, the code like this:
/**
* Get asset list using skip number
*
* */
public function getAssetListBySkip($number)
{
$propertyList = $this->_getEntityList("Assets()?".'$skip='.$number);
$result = array();
foreach ($propertyList as $properties) {
$result[] = Asset::createFromOptions($properties);
}
return $result;
}
We can call this method like this:
$mediaServiceProxy = ServicesBuilder::getInstance()->createMediaServicesService(
new MediaServicesSettings("**","**/**="));
$result=$mediaServiceProxy->getAssetListBySkip(1000);

Azure Media services supports filtering by name. You can construct web request to be like
/api/assets()?$filter=Name%20eq%20'Your Name'&$top=1
You can also filter by other properties

Have you tried REST API that are used when creating, processing, managing, and delivering Assets. https://msdn.microsoft.com/en-us/library/azure/hh974277.aspx#list_an_asset but I do think we can list asset via a name directly since id is an unique indentifier of asset entity. PHP Azure SDK leverages assetId to get an Asset as well:
public function getAsset($asset)
{
$assetId = Utilities::getEntityId(
$asset,
'WindowsAzure\MediaServices\Models\Asset'
);
return Asset::createFromOptions($this->_getEntity("Assets('{$assetId}')"));
}
But in my case, I don't have asset id with me. I just have asset name
alone. Now how do I get the asset details using this?
Here are some test function code snippets for your reference:
public function testListAllAssets(){
// Setup
$asset1 = new Asset(Asset::OPTIONS_NONE);
$asset1->setName(TestResources::MEDIA_SERVICES_ASSET_NAME . $this->createSuffix());
$asset2 = new Asset(Asset::OPTIONS_NONE);
$asset2->setName(TestResources::MEDIA_SERVICES_ASSET_NAME . $this->createSuffix());
// Test
$asset1 = $this->createAsset($asset1);
$asset2 = $this->createAsset($asset2);
$result = $this->restProxy->getAssetList();
// Assert
$this->assertCount(2, $result);
$names = array(
$result[0]->getName(),
$result[1]->getName()
);
$id = array(
$result[0]->getId(),
$result[1]->getId()
);
$this->assertContains($asset1->getName(), $names);
$this->assertContains($asset2->getName(), $names);
$this->assertContains($asset1->getId(), $id);
$this->assertContains($asset2->getId(), $id);
}
public function testGetAnAssetReference(){
// Setup
$assetName = TestResources::MEDIA_SERVICES_ASSET_NAME . $this->createSuffix();
$asset = new Asset(Asset::OPTIONS_NONE);
$asset->setName($assetName);
$asset = $this->createAsset($asset);
// Test
$result = $this->restProxy->getAsset($asset);
// Assert
$this->assertEquals($asset->getId(), $result->getId());
$this->assertEquals($asset->getName(), $result->getName());
}

According to my testing, it seems that we can’t use Asset’s name to get the information of asset in Media Service.
$mediaServiceProxy = ServicesBuilder::getInstance()->createMediaServicesService(
new MediaServicesSettings("**","******"));
$asset = new Asset(Asset::OPTIONS_NONE);
$asset->setName('For-Test-wmv-Source');
//$asset don't have the value of id,
// unless execute ‘createAsset($asset)’, "$asset1" will be set the ID
$asset1 =$mediaServiceProxy->createAsset($asset);
$result2=$mediaServiceProxy->getAsset($asset1);
PHP SDK support the method named “getAsset($asset)”. Actually, the method get the Asset information by Asset id, just like the Aka's reference code.And Azure REST API don’t support the method queried by Asset’s name.
Please refer to the official document.
Alternative approach is that you can store your assets information (such as Id,URl,name and ect.) into Azure table storage when you upload them into media service. If you want to use it, you can fetch and filter the data of Asset’s name you wants from table storage.
