php soap wsdl模式,PHP SOAP WSDL模式在方法调用上返回Null

我一直在尝试用PHP学习SOAP，非wsdl模式很好用 . 我将它们包含在寻求学习的人们的信息中 .

暴露library.php的类

class Library {

public function getDwarves(){

$dwarves = array("Bashful","Doc","Dopey");

return $dwarves;

}

public function greetUser($name){

return array("message"=>"hello,".$name);

}

}

?>

非wsdl客户端

try{

$options = array("location" => "http://192.168.1.20/ws/server.php" , "uri" => "http://192.168.1.20/ws");

$client=new SoapClient(null,$options);

$dwarves = $client->getDwarves();

echo nl2br("Result of getDwarves:\n");

var_dump($dwarves);

echo nl2br("\n\n");

$greeting = $client->greetUser("Fairmutex");

echo nl2br("Result of greetUser:\n");

var_dump($greeting);

echo nl2br("\n\n");

}catch(SoapFault $e){

var_dump($e);

echo "

".$e->getMessage()."

";

}

?>

非wsdl服务器

require('library.php');

$options = array("uri" => "http://192.168.1.20");

$server = new SoapServer(null,$options);

$server->setClass('Library');

$server->handle();

?>

但是，当WSDL被引入图片时，服务器返回NULL作为方法调用的结果 . 谁能帮我识别我做错了什么？

server.php

require('library.php');

$server = new SoapServer("wsdl");

$server->setClass('Library');

$server->handle();

?>

client.php

try{

$client=new SoapClient("http://192.168.1.20/ws/wsdl",array( "trace" => 1 ) );

$dwarves = $client->getDwarves();

echo nl2br("Result of getDwarves:\n");

var_dump($dwarves);

echo nl2br("\n\n");

$greeting = $client->greetUser("Fairmutex");

echo nl2br("Result of greetUser:\n");

var_dump($greeting);

echo nl2br("\n\n");

}catch(SoapFault $e){

var_dump($e);

echo "

".$e->getMessage()."

";

}

?>

client.php带有调试信息

try{

$client=new SoapClient("http://192.168.1.20/ws/wsdl",array( "trace" => 1 ) );

$dwarves = $client->getDwarves();

echo nl2br("GetFunctions:\n"); var_dump($client->__getFunctions()); echo nl2br("\n\n");

echo nl2br("GetTypes:\n"); var_dump($client->__getTypes()); echo nl2br("\n\n");

echo nl2br("Request Header:\n" . htmlentities(str_ireplace('>\n__getLastRequestHeaders())) . "\n");

echo nl2br("REQUEST:\n" . htmlentities(str_ireplace('>\n__getLastRequest())) . "\n");

echo nl2br("Response Header:\n" . htmlentities(str_ireplace('>\n__getLastResponseHeaders())) . "\n");

echo nl2br("Response:\n" . htmlentities(str_ireplace('>\n__getLastResponse())) . "\n");

echo nl2br("Result of getDwarves:\n");

var_dump($dwarves);

echo nl2br("\n\n");

$greeting = $client->greetUser("Fairmutex");

echo nl2br("REQUEST:\n" . htmlentities(str_ireplace('>\n__getLastRequest())) . "\n");

echo nl2br("Response Header:\n" . htmlentities(str_ireplace('>\n__getLastResponseHeaders())) . "\n");

echo nl2br("Response:\n" . htmlentities(str_ireplace('>\n__getLastResponse())) . "\n");

echo nl2br("Result of greetUser:\n");

var_dump($greeting);

echo nl2br("\n\n");

}catch(SoapFault $e){

var_dump($e);

echo "

".$e->getMessage()."

";

}

?>
