SOAP PHP 错误解析 WSDL: 无法加载外部实体?
我正在尝试使用PHP和SOAP运行Web服务,但到目前为止,我得到的只是:
(SoapFault)[2] 消息,其中指出:“SOAP 错误:解析 WSDL:无法从”http://localhost/MyRegistration/login.xml“加载:无法加载外部实体”http://localhost/MyRegistration/login.xml"
我尝试将localhost更改为127.0.0.1,但这没有任何区别。login实际上是一个wsdl文件,但是如果我将login.wsdl放在SOAPClient构造函数中,它会说“'看起来我们没有XML文档'”。
以下是我的 SOAP 客户端代码(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);
}
?>
下面是 login.wsdl 文件:
<?xml version="1.0"?>
<definitions name="LoginVal"
targetNamespace="urn:LoginVal"
xmlns:tns="urn:LoginVal"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns="http://schemas.xmlsoap.org/wsdl/">
<types>
<xsd:schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:Login">
<xsd:element name="getName" type="xsd:string" />
<xsd:element name="getPass" type="xsd:string" />
<xsd:element name="LoginResponse" type="xsd:string" />
</xsd:schema>
</types>
<message name="loginVerify">
<part name="username" type="tns:getName" />
<part name="password" type="tns:getPass" />
</message>
<message name="doLoginResponse">
<part name="return" type="tns:LoginResponse" />
</message>
<portType name="LoginPort">
<operation name="loginVerify">
<input message="tns: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>
我不确定这是否涉及,所以我提供了SOAP服务器注册的代码.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();
?>
我很抱歉,如果我提供了不必要的信息,但我是一个完全的新手 - 如果有人能指出为什么会产生这个SOAP错误,以及我能做些什么来纠正它,我将不胜感激。
我使用的是WAMP Server版本2.2,以及mySQL 5.5.24和PHP 5.3.13
