SOAP PHP故障解析WSDL:未能加载外部实体?

I'm trying to run a web service using PHP & SOAP, but all I'm getting so far is this:

我尝试使用PHP和SOAP运行web服务，但目前为止我所得到的只是:

(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"

[2]消息，该消息声明:“SOAP-ERROR:解析WSDL:无法从”http://localhost/MyRegistration/login装载。xml':未能加载外部实体“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.

我尝试将localhost更改为127.0.0.1，但这没有什么区别。登录实际上是一个wsdl文件，但是如果我输入login。在SOAPClient构造函数中，它说“看起来我们没有XML文档”。

Here is my code for the SOAP Client (register_client.php):

下面是SOAP客户机的代码(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);
}
?> 

And here is the login.wsdl file:

这是登录名。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>

And I'm not sure if this is involved, so I'm providing the code for the SOAP Server register.php:

我不确定是否涉及到这一点，所以我提供了SOAP服务器注册器的代码。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();
?>

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.

如果我提供了不必要的信息，我很抱歉，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，我将非常感激。

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.

在迁移到PHP 5.6.5之后，soap 1.2不再工作了。因此，我通过添加可选的SSL参数解决了这个问题。

My error:

我的错误:

failed to load external entity

未能加载外部实体

How to solve:

如何解决:

// 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);

#2

Put this code above any Soap call:

将此代码置于任何Soap调用之上:

libxml_disable_entity_loader(false);

#3

On register_client.php make sure that the URL that has been passed to SoapClient is accessible from the machine you're executing the code.

register_client。php确保传递给SoapClient的URL可以从正在执行代码的机器中访问。

$sClient = new SoapClient('http://127.0.0.1/MyRegistration/login.wsdl');    

If 127.0.0.0 does not work you can try using some network IP address and see.

如果127.0.0.0不起作用，您可以尝试使用一些网络IP地址并查看。

Let me know if it still does not fix it for you, I did try with your example and changing path (making it proper in my dev. environment) has fixed same error for me.

如果它还没有为您修复，请告诉我，我确实尝试了您的示例和更改路径(使它在我的devi环境中是正确的)对我有相同的错误。

I would be interested to know if it does not fix it for you.

我很想知道它是否能帮你修好。

I had the same problem.

我也有同样的问题。

This php setting solved my problem:

这个php设置解决了我的问题:

allow_url_fopen -> 1

#5

try this. works for me

试试这个。适合我

$options = array(
    'cache_wsdl' => 0,
    'trace' => 1,
    'stream_context' => stream_context_create(array(
          'ssl' => array(
               'verify_peer' => false,
                'verify_peer_name' => false,
                'allow_self_signed' => true
          )
    ))

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

#6

If anyone has the same problem, one possible solution is to set the bindto stream context configuration parameter (assuming you're connecting from 11.22.33.44 to 55.66.77.88):

如果有人有同样的问题，一个可能的解决方案是设置bindto流上下文配置参数(假设您正在从11.22.33.44连接到55.66.77.88):

$context = [
    'socket' => [
        'bindto' => '55.66.77.88'
    ]
];

$options = [
    'soapVersion' => SOAP_1_1,
    'stream_context' => stream_context_create($context)
];

$client = new Client('11.22.33.44', $options);

Got a similar response with https WSDL URL using php soapClient

使用php soapClient获得与https WSDL URL类似的响应

SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from ...

SoapFault exception: [WSDL] SOAP-ERROR:解析WSDL:无法从…

After server has been updated from PHP 5.5.9-1ubuntu4.21 >> PHP 5.5.9-1ubuntu4.23 something went wrong for my client machine osx 10.12.6 / PHP 5.6.30, but MS Web Services Clients connections could be made without issues.

从PHP 5.5.9-1ubuntu4.21 >> > PHP 5.5.9-1ubuntu4.23更新服务器后，我的客户机器osx10.12.6 / PHP 5.6.30出现了问题，但Web服务客户端连接可以没有问题。

Apache2's server_access.log showed no entry when i tried to load WSDL so i added 'cache_wsdl' => WSDL_CACHE_NONE to prevent client-side wsdl caching, but still got no entries. Finally i tried to load wsdl per CURL -i checked HEADERS but all seemed to be ok..

输入的server_access。当我尝试加载WSDL时，日志没有显示条目，所以我添加了'cache_wsdl' => WSDL_CACHE_NONE以防止客户端WSDL缓存，但是仍然没有条目。最后，我尝试每卷加载wsdl -我检查了标题，但似乎一切正常。

Only libxml_get_last_error() provided some insight > SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

只有libxml_get_last_error()提供了一些代码1失败的> SSL操作。OpenSSL错误消息:错误:14090086:SSL例程:SSL3_GET_SERVER_CERTIFICATE:证书验证失败

So I added some ssl options to my call:

所以我在电话中加入了一些ssl选项:

$contextOptions = array(
    'ssl' => array(
    'verify_peer' => false,
    'verify_peer_name' => false,
    'allow_self_signed' => true
    ));

$sslContext = stream_context_create($contextOptions);

$params =  array(
    'trace' => 1,
    'exceptions' => true,
    'cache_wsdl' => WSDL_CACHE_NONE,
    'stream_context' => $sslContext
    );

try {
    $proxy = new SoapClient( $wsdl_url, $params );
} catch (SoapFault $proxy) {
    var_dump(libxml_get_last_error());
    var_dump($proxy);
}

In my case 'allow_self_signed' => true did the trick!

在我的例子中，allow_self_signed' => true做到了!
