I'm trying to run a web service using PHP & SOAP, but all I'm getting so far is this:
(SoapFault)[2] message which states: 'SOAP-ERROR: Parsing WSDL: Couldn't load from 'http://localhost/MyRegistration/login.xml' : failed to load external entity "http://localhost/MyRegistration/login.xml"
I've tried changing localhost to 127.0.0.1, but that makes no difference. login is actually a wsdl file, but if I put login.wsdl in the SOAPClient constructor, it says "'looks like we got no XML document'" instead.
Here is my code for the SOAP Client (register_client.php):
<?php
try
{
$sClient = new SoapClient('http://127.0.0.1/MyRegistration/login.wsdl');
$param1 = $_POST["regname"];
$param2 = $_POST["regpass1"];
$response = $sClient->loginVerify($param1, $param2);
var_dump($response);
}
catch(SoapFault $e)
{
var_dump($e);
}
?>
And here is the login.wsdl file:
<?xml version="1.0"?>
<definitions name="LoginVal"
targetNamespace="urn:LoginVal"
xmlns:tns="urn:LoginVal"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"

xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

<types>
<xsd:schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:Login">

<message name="loginVerify">

</message>
<portType name="LoginPort">
<operation name="loginVerify">

<output message="tns:doLoginResponse" />
</operation>
</portType>
<binding name="LoginBinding" type="tns:LoginPort">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />
<operation name="loginVerify">
<soap:operation soapAction="urn:LoginAction" />
<input>
<soap:body use="encoded" namespace="urn:Login" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
</input>
<output>
<soap:body use="encoded" namespace="urn:Login" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />
</output>
</operation>
</binding>
<service name="LoginService">
<port name="LoginPort" binding="tns:LoginBinding">
<soap:address location="http://localhost/MyRegistration/register.php" />
</port>
</service>
</definitions>
And I'm not sure if this is involved, so I'm providing the code for the SOAP Server register.php:
<?php
if(!extension_loaded("soap"))
{
dl("php_soap.dll");
}
ini_set("soap.wsdl_cache_enabled", "0");
$server = new SoapServer("login.wsdl", array('uri'=>'http://127.0.0.1/MyRegistration'))
public function loginVerify($username, $password)
{
if($_POST["regname"] && $_POST["regemail"] && $_POST["regpass1"] && $_POST["regpass2"] )
{
if($_POST["regpass1"] == $_POST["regpass2"])
{
$servername = "localhost";
$username = "root";
$password = "Hellfire";
$conn = mysql_connect($servername,$username,"Hellfire")or die(mysql_error());
mysql_select_db("soap",$conn);
$sql = "insert into users (name,email,password)values('$_POST[regname]','$_POST[regemail]','$_POST[regpass1]')";
$result = mysql_query($sql,$conn) or die(mysql_error());
return "You have registered sucessfully";
//print "<a href='index.php'>go to login page</a>";
}
else return "passwords dont match";
}
else return "invalid data";
}
$server->AddFunction("loginVerify");
$server->handle();
?>
I'm sorry if I'm giving unnecessary information, but I'm a complete novice at this - and I'd really appreciate it if someone could point out why exactly this SOAP Fault is being generated, and what I can do to rectify it.
I am using WAMP Server version 2.2, with mySQL 5.5.24 and PHP 5.3.13
After migrating to PHP 5.6.5, the soap 1.2 did not work anymore. So I solved the problem by adding optional SSL parameters.
My error:
failed to load external entity
How to solve:
// options for ssl in php 5.6.5
$opts = array(
'ssl' => array(
'ciphers' => 'RC4-SHA',
'verify_peer' => false,
'verify_peer_name' => false
)
);
// SOAP 1.2 client
$params = array(
'encoding' => 'UTF-8',
'verifypeer' => false,
'verifyhost' => false,
'soap_version' => SOAP_1_2,
'trace' => 1,
'exceptions' => 1,
'connection_timeout' => 180,
'stream_context' => stream_context_create($opts)
);
$wsdlUrl = $url . '?WSDL';
$oSoapClient = new SoapClient($wsdlUrl, $params);
