php使用nusoap创建WebService

service:

include_once("utils/lib/nusoap.php"); //加载nusoap库文件
$server = new soap_server(); //生成对象
$server->configureWSDL("screenshot_wsdl", "urn:screenshot_wsdl");
$server->register("screenshot", //调用方法
	array( //输入参数
		"key" => "xsd:string", //字符串类型
		"arraykey" => "xsd:array", //数组类型
	),
	array( //输出参数
		"returnstring" => "xsd:string",
		"returnarray" => "xsd:array",
	),
	"urn:screenshot_wsdl", //名字空间
	"urn:screenshot_wsdl#screenshot", //名字空间#要操作的函数名
	"rpc", //style
	"encoded", //use
	"screenshot for webpage!"//说明
);
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : ""; //Use the request to (try to) invoke the service
$server->service($HTTP_RAW_POST_DATA);
/**
 * 处理截图请求方法
 * @param $url
 * @param $key
 * @return array|soap_fault
 */
function screenshot($key, $arraykey)
{
	return ['returnstring' => $key, 'returnarray' => $arraykey];
}

client: 

include_once("utils/lib/nusoap.php"); //加载nusoap库文件
//设置参数数组
$para = array(
	"key" => "test",
	"arraykey" => [1, 2],
);
$client = new nusoap_client("http://localhost/jietu/soap_server.php?WSDL"); //访问的WebService地址
$return = $client->call('screenshot', $para); //发送请求
print_r($return); //输出返回结果
var_dump($client->getError()); //显示错误
