前回のエントリの続きですが、Zend AMF を使用して画像のバイナリデータを取得するときの注意事項は、以下の 2 点です。
- AMF3 形式で通信
- Zend_Amf_Value_ByteArray API で、AS3 の ByteArray 型に変換
例 :
service.php
<?php
require_once 'Zend/Amf/Server.php';
require_once 'Zend/Amf/Value/ByteArray.php';
$server = new Zend_Amf_Server();
$server->setClass('PHPService');
$server->setClassMap('TestResultVO', 'TestResult');
$response = $server->handle();
echo $response;
class PHPService {
public function test($args) {
$filename = 'hoge.jpg';
$file = fopen($filename,'rb');
$content = fread($file, filesize($filename));
fclose($file);
$result = new TestResult();
$result->bytes = new Zend_Amf_Value_ByteArray($content);
return $result;
}
}
class TestResult {
public $bytes;
}
?>
Test.mxml
