使用pear::soap建立web服務的步驟

複製代碼

class FruitQuoteService
{
 public $__dispatch_map = array();
 public $__type = array();
 public $__type defy(
 public function FruitQuoteService()
 {
 $this->__dispatch_map['getQuote'] = array(
 "in" => array("category" => "string") ,
 "out" => array("quote" => "int")
 );
 $this->__dispatch_map['getFruit'] = array(
 "in" => array(),
 "out" => array("fruitSummary" => "{urn:FruitQuoteService}fruitStruct")
 );

 $this->__typedef ['fruitStruct'] = array(
 $this->__typedef ['fruitStruct'] = array(
 '類別'=>'字串', '金額' => 'int'
 );
 }

 public function getQuote($category)
 {
 switch ($category)
 {
 case 'apple': 中斷;
 case '橘色':
 $quote = 12;
 中斷;
 case '香蕉':
 $quote = 20;
 中斷;
 預設:
 $quote = 0;
 break;
 }
 return $quote;
 }//函數結束

 public function getFruit()
 {
 $list = array(
 array("蘋果", 100),
 array("柳橙", 500),
 array("香蕉", 260)
 );
 return $list;
 }//結束函數
}//結束類別
?>

第二步：建立伺服器.php 這個程式將會接收並處理客戶端的請求

require_once("FruitQuoteService.php");
require_once("SOAP/Server.php");
 $fruitQuote = new FruitQuoteService();
$server = new Soap_Server();
$server->addObjectMap($fruitQuote, "http://www.xxx.com");
if (isset ($_SERVER['REQUEST_METHOD']) && $_SERVER['REQUEST_METHOD']=='POST')
{
 $server->service($GLOBALS['HTTP_RAW_POST_DATA']);
} else
{
 require_once 'SOAP/Disco.php';
 $disco = new SOAP_DISCO_Server($server,'FruitQuoteService');
 header("內容類型：text/xml" );
 if (isset($_SERVER['QUERY_STRING']) && strcasecmp($_SERVER['QUERY_STRING'],'wsdl')==0) {
 echo $disco->getWSDL();
 } else {
 echo $disco->getDISCO();
 }
}
退出;
?>

現在可以透過http://www.shangyong.com/ws/server.php?wsdl查看wsdl文件。

DISCO：一項微軟用於發布和發現 Web 服務的技術，定義了一個從給定的 url 獲取 Web 服務描述的簡單的 HTTP GET 機制

第三步：建立web服務客戶端程式碼

require_once('SOAP/Client.php');
//該名稱空間必須和server.php定義的一致
$options = array('namespace' => 'http://www.xxx.com',
 'trace' => 1); //為1可以表示透過__get_wire取得soap訊息，預設為0
$client = new SOAP_client("http://www.shangyong.com/ws/server.php");
$params = array();
$response = $client->call("getFruit", $params, $options);
//print_r($client->__get_wire()); // 輸出soap訊息
if (PEAR::isError($response)) {
 echo 'Error: ' . $response->getMessage() 。 "n";
} else {
 print_r($response) 。 "n";
}
$params = array("name" => "orange");
$response = $client->call("getQuote", $params, $options) ;
if (PEAR::isError($response)) {
 echo '錯誤：' 。 $response->getMessage() 。 。 "nn";
}
退出;
?>
