Server端示例:

function test($x) {
return $x;
}
$ss = new SoapServer('http://localhost/00/wsdl.xml');
$ss->addFunction('test');
$ss->handle();

Client调用:

$soap = new soapClient('http://localhost/00/wsdl.xml',array('trace'=>true));
var_dump($soap->test('10086'));

传递和返回数组参数
如果传递或返回的参数为数组,可以在message标签中做说明.

'testRequest'>
"term" type="xsd:ArrayOfString"/>

'testResponse'>
"value" type="xsd:ArrayOfString"/>

XML-RPC调用

XML-RPC可以理解为简化版的soap,对数据的包装相对简洁.
php.ini中,要打开extension=php_xmlrpc.dll

/*
求和函数
注意,rpc服务器在调用函数时,传的参数是这样的:
array(0=>'函数名' , 1=>array(实参1,实参2,...实参N) , 2=>NULL)
*/
function hello() {
return 'hello';
}
function sum($method , $args , $extra) {
return array_sum($args);
}
// 创建RPC Server
$server = xmlrpc_server_create ();
xmlrpc_server_register_method ($server , 'hello' , 'hello');
xmlrpc_server_register_method ($server , 'sum' , 'sum');
// 收取请求
$request = $HTTP_RAW_POST_DATA;
//执行调用客户端的XML请求后获取执行结果
$xmlrpc_response = xmlrpc_server_call_method($server, $request , null);
//把函数处理后的结果XML进行

客户端:

class rpcclient {
protected $url;
public function __construct($url='' ) {
$this->url = $url;
}
protected function query($request) {
$context = stream_context_create(array('http' => array(
'method' => "POST",
'header' => "Content-Type: text/xml",
'content' => $request
)));
$xml = file_get_contents($this->url, false, $context);
return xmlrpc_decode($xml);
}
public function __call($method , $args) {
$request = xmlrpc_encode_request($method , $args);
return $this->query($request);
}
}
$rpc = new rpcclient('http://localhost/00/rpcs.php');
var_dump($rpc->hello());
var_dump($rpc->sum(4,5,6));

WebService与json Api的区别

　　　　　　WebService　　 json API
数据封装　　XML 　　　　　　json
复杂度　　　高　　　　　　　 低
底层协议 不限　　　　　　 HTTP
数据类型 可严格定义　　　 不可严格定义
自说明 性自说明　　　　需额外API文档
