我正在尝试自学SOAP，只是为了扩展我的技能组合，但是我已经碰壁了，我想知道那里的善良开发者是否可以提供帮助？
我已经设置了我的服务器：
http://www.domain1.com/server.php
<?php
// Pull in the NuSOAP code
require_once('soap/nusoap.php');
// Create the server instance
$server = new soap_server();
// Initialize WSDL support
$server->configureWSDL('hellowsdl', 'urn:hellowsdl');
// Register the method to expose
$server->register('hello', // method name
array('name' => 'xsd:string'), // input parameters
array('return' => 'xsd:string'), // output parameters
'urn:hellowsdl', // namespace
'urn:hellowsdl#hello', // soapaction
'rpc', // style
'encoded', // use
'Says hello to the caller' // documentation
);
// Define the method as a PHP function
function hello($name) {
return 'Hello, ' . $name;
}
// Use the request to (try to) invoke the service
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>
现在我尝试在单独的服务器上设置客户端：
http://www.domain2.com/client.php
<?php
// Pull in the NuSOAP code
require_once('soap/nusoap.php');
// Create the client instance
$client = new soapclient('http://domain.com/server.php?wsdl', true);
// Check for an error
$err = $client->getError();
if ($err) {
// Display the error
echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
// At this point, you know the call that follows will fail
}
// Call the SOAP method
$result = $client->call('hello', array('name' => 'Scott'));
// Check for a fault
if ($client->fault) {
echo '<h2>Fault</h2><pre>';
print_r($result);
echo '</pre>';
} else {
// Check for errors
$err = $client->getError();
if ($err) {
// Display the error
echo '<h2>Error</h2><pre>' . $err . '</pre>';
} else {
// Display the result
echo '<h2>Result</h2><pre>';
print_r($result);
echo '</pre>';
}
}
// Display the request and response
echo '<h2>Request</h2>';
echo '<pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';
echo '<h2>Response</h2>';
echo '<pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre>';
// Display the debug messages
echo '<h2>Debug</h2>';
echo '<pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre>';
?>
但我无法让这件事情发挥作用。服务器显示正常 - wdsl输出该批次。但客户端无法/不会连接并完成交易。我收到这条消息：
Warning: SoapClient::SoapClient() expects parameter 2 to be array, boolean given in /home/public_html/slidebank_soap_client.php on line 5
Fatal error: Uncaught SoapFault exception: [Client] SoapClient::SoapClient() [<a href='soapclient.soapclient'>soapclient.soapclient</a>]: Invalid parameters in /home/soap/slidebank_soap_client.php:5 Stack trace: #0 /home/soap/slidebank_soap_client.php(5): SoapClient->SoapClient('http://testing....', true) #1 {main} thrown in /home/public_html/soap/slidebank_soap_client.php on line 5
这就是我难倒的地方......
有什么想法吗？

这thread可能会对您有所帮助，尤其是回答＃9和＃10。
答案 1 :(得分：1)
我曾经是使用PHP3 / 4的nusoap的粉丝（也就是当PHP没有内置的SOAP客户端时）但是使用PHP5的SOAP客户端我发现这些天我没有任何需要nusoap。
PHP5内置的SOAP客户端的一个优点是它实现起来更清晰，更简单，所以提及它可能对你有帮助（我知道有些人选择使用nusoap，但很多人显然不是意识到它存在于PHP5中，因为很多“HOWTO”指南已经过时而忽略了它。）
使用示例：
ini_set("soap.wsdl_cache_enabled", "1"); // Set to zero to avoid caching WSDL
$soapClient = new SoapClient('http://www.example.com/webservices/HelloWorldService/?wsdl");
$result = $soapClient->HelloWorldMethod(array('string' => "hello!"));
print_r($result);
关于服务类型的说明：
对于SOAP服务，理想情况下，您希望实现Document / Literal服务，而不是RPC / Encoded服务，因为RPC / Encoded是一种难以使用的格式，因此已被弃用WS-I支持Document / Literal（在设计中更易于使用和更合理）。
首先，如果可以，您可能希望尝试针对现有服务实施客户端 - 这样您就知道它至少可以正常工作，这可能会让您感到头疼。
不幸的是 - 虽然它非常适合消费它们 - 但PHP并没有特别支持提供文档/文字服务。这个IIRC至少有一个第三方类似nusoap的图书馆，但它并没有为我完全削减它。
（如果其中任何一个已过时，欢迎更正。）

以防一些googlers发现这个...
我按照ccheneson的建议编辑了php.ini，这段代码运行得很好，即使在同一台开发服务器上也是如此。
客户端 - 基于PHP模式的Drupal页面：
<?php
# URL for the service WSDL
ini_set("soap.wsdl_cache_enabled", "0"); // Set to zero to avoid caching WSDL
try {
// Get a service proxy from the WSDL
$proxy = new SoapClient('http://testing.domain.com/soap.php?wsdl');
global $user;
if (is_array($user->roles) && in_array('group1', array_values($user->roles))) {
// User is logged in and is in the usergroup, perform login
$id = $user->uid;
$key = 1234;
$hashgenerator = $key . "xyz" . $id . "randomstringhere";
$hash = sha1($hashgenerator);
// Call a method on the service via the proxy
$result = $proxy->handshake($id, $key, $hash);
if ($hash==$result) {
//Send all user details
profile_load_profile($user);
$email = $user->mail;
$fname = $user->{profile_firstname};
$lname = $user->{profile_lastname};
$phone = $user->{profile_phone};
$fax = $user->{profile_fax};
$dept = "Speakers";
$role = "Speakers";
//Send request
$authresult = $proxy->authlogin($id, $email, $fname, $lname, $phone, $fax, $authgroup);
if ($authresult=='ok') {
//Logged in, show them the page
$_SESSION['loggedin'] = 1;
} else {
echo "Error 3";
}
} else {
echo "Error 2";
}
} else {
echo "Error 1";
}
} catch(SoapFault $ex) {
echo 'Error: ';
if ($ex->getMessage() != '') {
echo $ex->getMessage();
} else {
echo $ex . "\n";
}
}
?>
服务：
<?php
//----------------------------------//
// This file is a dummy service It obviously does nothing with the data, but i needed it to build my client scripts and so it might give you a hand returning the correct strings.
//----------------------------------//
// Pull in the NuSOAP code
require_once('nusoap/nusoap.php');
// Create the server instance
$server = new soap_server();
// Initialize WSDL support
$server->configureWSDL('WDSL', 'urn:WDSL');
// Register the methods to expose
$server->register('handshake', // method name
array('id' => 'xsd:string',
'key' => 'xsd:string',
'hash' => 'xsd:string'),
array('return' => 'xsd:string'), // output parameters
'urn:WDSL', // namespace
'urn:WDSL#_handshake', // soapaction
'rpc', // style
'encoded', // use
'Initial handshake' // documentation
);
$server->register('authlogin', // method name
array('id' => 'xsd:string', // User ID
'email' => 'xsd:string', // User email address
'fname' => 'xsd:string', // User first name
'lname' => 'xsd:string', // User last name

'urn:WDSL', // namespace
'urn:WDSL#authlogin', // soapaction
'rpc', // style
'encoded', // use
'Authentication of a user' // documentation
);
// Define the method as a PHP function
function slidebank_handshake($uid, $key, $hash) {
//returns the same hash string for confirmation. No need to pass UID again.
$hashgenerator = $key . "xyz" . $uid . "randomstringhere";
$hash = sha1($hashgenerator);
return $hash;
}
// Define the method as a PHP function
function slidebank_authlogin($id, $email, $fname, $lname, $phone, $fax, $dept, $role) {
//logic to log user in and capture details etc
return 'ok'; //options = ok or fail
}
// Use the request to (try to) invoke the service
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>
