如何将SOAP调用交换到cURL,以便在allow_url_fopen限制内工作？

Question

我最近遇到了一个问题,即对ID3Global /地址服务的SOAP调用突然停止工作(它们之前工作正常).我认为它与托管服务提供商关闭allow_url_fopen我们的服务器有关,现在意味着该服务不起作用.

我被告知我需要切换到使用cURL来获取文件(WSDL),因为file_get_contents需要在php.ini文件中设置'allow_url_fopen'才能使其工作.但是我似乎没有file_get_contents在我的文件中使用来获取WSDL文件.

如何切换到使用cURL？

这是我的PHP文件调用SOAP地址:

<?php
ini_set("soap.wsdl_cache_enabled", "0");

$username = 'xxxxxxx@xxxxxxxx.com';
$password = 'xxxxxxx';

$profile_id = 'xxxxxx-xxxx-xxxx-xxxx-xxxxxxxx';

// Live WSDL
$wsdl = 'https://id3global.com/ID3gWS/ID3global.svc?wsdl';

$postcode = $_POST['ZipPostcode'];

/**
 * Method to arrange the address into a sane
 * order for displaying back to the user
 *
 * @param $item
 * @param $key
 * @internal param $address
 */
function sortAddress(&$item, $key)
{
    // Convert the object to an array
    $address = (array) $item;

    // Reorder the address lines
    $addressLines = array(
        'Company' => $address['Company'],
        'Building' => $address['Building'],
        'SubBuilding' => $address['SubBuilding'],
        'Premise' => $address['Premise'],
        'SubStreet' => $address['SubStreet'],
        'Street' => $address['Street'],
        'City' => $address['City'],
        'StateDistrict' => $address['StateDistrict'],
        'ZipPostcode' => $address['ZipPostcode'],
        'Country' => $address['Country'],
    );

   // Remove blank address lines
   // $item = array_filter($addressLines);
   $item = $addressLines;

}

class clsWSSEAuth { 
    private $Username; 
    private $Password;  
    function __construct($username, $password) { 
        $this->Username=$username; 
        $this->Password=$password; 
    } 
} 

class clsWSSEToken { 
    private $UsernameToken; 
    function __construct ($UsernameToken){ 
        $this->UsernameToken = $UsernameToken; 
    } 
} 

$strWSSENS = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"; 

//Auth
$objSoapVarUser = new SoapVar($username, XSD_STRING, NULL, $strWSSENS, NULL, $strWSSENS); 
$objSoapVarPass = new SoapVar($password, XSD_STRING, NULL, $strWSSENS, NULL, $strWSSENS); 
$objWSSEAuth = new clsWSSEAuth($objSoapVarUser, $objSoapVarPass); 

//Token
$objSoapVarWSSEToken = new SoapVar($objWSSEAuth, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS); 
$objWSSEToken = new clsWSSEToken($objSoapVarWSSEToken); 

//Header
$objSoapVarWSSEAuth = new SoapVar($objWSSEToken, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'UsernameToken', $strWSSENS); 
$objSoapVarHeaderVal = new SoapVar($objSoapVarWSSEAuth, SOAP_ENC_OBJECT, NULL, $strWSSENS, 'Security', $strWSSENS); 
$objSoapVarWSSEHeader = new SoapHeader($strWSSENS, 'Security', $objSoapVarHeaderVal, true); 

//Client
$client = new SoapClient($wsdl, array(
    'soap_version' => SOAP_1_1, 
    'trace' => 1, 
    'exception' => true, 
)); 

$client->__setSoapHeaders($objSoapVarWSSEHeader);

$results = $client->AddressLookup(array(
    'InputData' => array('ZipPostcode' => strtoupper($postcode)),
));

$addresses = $results->AddressLookupResult->GlobalAddress;


array_walk($addresses, 'sortAddress');
//var_dump($addresses);

echo json_encode( $addresses );

这是使用AJAX触发的,这是JavaScript/jQuery文件:

jQuery(document).ready(function($) {

    var addresses = [];

    $("body").on('click', '.find-address', function(e){
        e.preventDefault();
        url = '/wp-content/themes/Cornhill/gbgroup-address-lookup_2.php';
        postode_id = $(this).data('postcode');
        address_id = $(this).data('address');
        postcode = $('#'+postode_id).val();
        console.log('Stage 1');

        if (postcode != '')
        {
            var addressList = $('#'+address_id);
            addressList.find('option').remove();
            opt = $('<option>').html('Loading...');
            opt.val('');
            addressList.append(opt);
            console.log('stage 2');

            $.ajax({
                url: url,
                dataType: 'json',
                type: 'post',
                data: {
                    'ZipPostcode': postcode
                },
                success: function(response){
                    addressList.find('option').remove();
                    addresses[address_id] = response;

                    opt = $('<option>').html('Please select');
                    opt.val('');
                    addressList.append(opt);

                    for(x=0; x<addresses[address_id].length; x++){

                        addressArray = new Array();
                        addressArray.push(addresses[address_id][x].Building);
                        addressArray.push(addresses[address_id][x].Street);
                        addressArray.push(addresses[address_id][x].City);
                        addressArray.push(addresses[address_id][x].ZipPostcode);

                        addressString = addressArray.join(', ');

                        opt = $('<option>').attr('value', x);
                        opt.html(addressString);

                        addressList.append(opt);
                    }
                }
            });
        }
        else
        {
            return;
        }
    });

    $("body").on('change', '.select-address', function(){
        address_id = $(this).attr('id');
        street_id = $(this).data('street');
        town_id = $(this).data('town');
        postcode_id = $(this).data('postcode');

        value = $(this).val();
        if(value != ''){
            address = addresses[address_id][value];

            if (address.Building != '')
            {
                $('#'+street_id).val(address.Building+' '+address.Street);
            }
            else
            {
                $('#'+street_id).val(address.Street);
            }
            $('#'+town_id).val(address.City);
            $('#'+postcode_id).val(address.ZipPostcode);
        }

    });

});

我之前尝试使用以下代码切换来获取WSDL文件,但我不确定我应该用它做什么:

$ch =  curl_init('https://id3global.com/ID3gWS/ID3global.svc?wsdl');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$resultSuper = curl_exec($ch);

该参数allow_url_fopen对 SOAP 的工作方式没有影响。您可以使用以下脚本轻松测试：

<?php

echo "allow_url_fopen status is: " . ini_get('allow_url_fopen') . "\n";

$wsdl = 'https://id3global.com/ID3gWS/ID3global.svc?wsdl';

file_get_contents($wsdl);

$client = new SoapClient($wsdl, array(
    'soap_version' => SOAP_1_1,
    'trace' => 1,
    'cache_wsdl' => WSDL_CACHE_NONE, // this is important for the purpose of the test
    'exception' => true,
));

print_r($client);

?>

当启用allow_url_fopen时，您将看到以下输出：

allow_url_fopen status is: 1 SoapClient Object ( [trace] => 1 [_soap_version] => 1 [sdl] => Resource id #11 )

当allow_url_fopen被禁用时，您将看到以下输出：

allow_url_fopen status is: 0 
Warning: file_get_contents(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /var/www/test.php on line 9

Warning: file_get_contents(https://id3global.com/ID3gWS/ID3global.svc?wsdl): failed to open stream: no suitable wrapper could be found in /var/www/test.php on line 9
SoapClient Object ( [trace] => 1 [_soap_version] => 1 [sdl] => Resource id #10 )

请注意，没有报告 SOAP 错误。

出现此行为的原因是ext/soap/php_xml.cPHP 源文件中的以下代码：

old_allow_url_fopen = PG(allow_url_fopen);
PG(allow_url_fopen) = 1;
ctxt = xmlCreateFileParserCtxt(filename);
PG(allow_url_fopen) = old_allow_url_fopen;

因此，为 WSDL 下载启用了allow_url_fopen。如果您按如下方式注释这些行：

/* old_allow_url_fopen = PG(allow_url_fopen);
PG(allow_url_fopen) = 1; */
ctxt = xmlCreateFileParserCtxt(filename);
/* PG(allow_url_fopen) = old_allow_url_fopen; */

然后使用更改后的源代码编译 PHP，您将看到以下结果：

启用allow_url_fopen：

allow_url_fopen status is: 1 SoapClient Object ( [trace] => 1 [_soap_version] => 1 [sdl] => Resource id #11 )

禁用allow_url_fopen：

allow_url_fopen status is: 0 
Warning: file_get_contents(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /var/www/test.php on line 9

Warning: file_get_contents(https://id3global.com/ID3gWS/ID3global.svc?wsdl): failed to open stream: no suitable wrapper could be found in /var/www/test.php on line 9

Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://id3global.com/ID3gWS/ID3global.svc?wsdl' : failed to load external entity "https://id3global.com/ID3gWS/ID3global.svc?wsdl" in /var/www/test.php:16 Stack trace: #0 /var/www/test.php(16): SoapClient->SoapClient('https://id3glob...', Array) #1 {main} thrown in /var/www/test.php on line 16

您可以看到，这次我们出现了致命的 SOAP 错误，并且无法加载 WSDL。我在 PHP 5.4.40 和 PHP 5.6.8 中观察到了这种行为。
