Question

我需要为opencart创建付款模块。如何在php中构建xml输出以将其发布到远程租赁服务器URL的问题：https://ecredit.leasing.com/eshop_test/UBLOnline.aspx?eshopdata=?

使用post方法。我试图构建这个xml：

<?xml version="1.0" encoding="UTF-8"?>
<ContractRequest xmlns="http://e-credit.ubl.lt/eshop" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://e-credit.ubl.lt/eshop http://e-credit.leasing.com/eshop/contractrequest.xsd">
    <SaleLogin>test</SaleLogin>
    <SaleConditionID>111</SaleConditionID>
    <Person>
        <FirstName>John</FirstName>
        <LastName>Jones</LastName>
    </Person>
    <Communication>
        <StreetOrVillage>First</StreetOrVillage>
        <City>New York</City>
        <PostCode>21212</PostCode>
        <Phone>+100000000</Phone>
        <Email>john@mymail.com</Email>
    </Communication>
    <ContractDetails>
        <CreditAmount>617.60</CreditAmount>
        <CreditCurrency>USD</CreditCurrency>
    </ContractDetails>
    <OrderedItemsDetail>
        <Item>
            <Name>1 x HP 250 G5 UMA Celeron N3060 15.6 HD SVA, 1 x HP 15-r101na 15.6 HD Brightview flat (B), </Name>
            <Amount>2pcs.</Amount>
            <Price>617.60</Price>
            <Currency>USD</Currency>
        </Item>
    </OrderedItemsDetail>

</ContractRequest>

我试过像这样创建xml：

$XmlString =  '<?xml version="1.0" encoding="UTF-8" ?>'; 
                  $XmlString .= '<ContractRequest 
    xmlns="http://e-credit.ubl.lt/eshop"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://e-credit.ubl.com/eshop http://e-credit.leasing.com/eshop/contractrequest.xsd">'; 


    $XmlString .= '<SaleLogin>' . $data['SaleLogin'] . '</SaleLogin>';
    $XmlString .= '<SaleConditionID>' . $data['SaleConditionID'] . '</SaleConditionID>'; 

    $XmlString .= '<Person>';  
        $XmlString .= '<FirstName>' . $data['first_name'] . '</FirstName>'; 
        $XmlString .= '<LastName>' . $data['last_name'] . '</LastName>'; 

    $XmlString .= '</Person>'; 

    $XmlString .= '<Communication>';
        $XmlString .= '<StreetOrVillage>' . $data['street'] . '</StreetOrVillage>'; 
        $XmlString .= '<City>' . $data['city'] . '</City>'; 
        $XmlString .= '<PostCode>' . $data['postcode'] . '</PostCode>'; 
        $XmlString .= '<Phone>' . $data['telephone'] . '</Phone>'; 
        $XmlString .= '<Email>' . $data['email'] . '</Email>'; 
    $XmlString .= '</Communication>'; 

    $XmlString .= '<ContractDetails>';

        $XmlString .= '<CreditAmount>' . $data['amount'] . '</CreditAmount>'; 
        $XmlString .= '<CreditCurrency>' . $data['currency'] . '</CreditCurrency>'; 
    $XmlString .= '</ContractDetails>'; 

    $XmlString .= '<OrderedItemsDetail>';
        $XmlString .= '<Item>';
            $XmlString .= '<Name>' . $data['description'] . '</Name>'; 
            $XmlString .= '<Amount>' . $data['products_amount'] . '</Amount>'; 
            $XmlString .= '<Price>' . $data['amount'] . '</Price>'; 
            $XmlString .= '<Currency>' .$data['currency'] . '</Currency>'; 
        $XmlString .= '</Item>'; 
    $XmlString .= '</OrderedItemsDetail>'; 


$XmlString .= '</ContractRequest>';

之后：

$url = https://ecredit.leasing.com/eshop_test/UBLOnline.aspx?eshopdata=?;
$header = array();

                        $header[] = 'Content-Type: text/xml';
                        $header[] = 'Content-Length: ' . strlen($XmlString);

                        $ch = curl_init();

                        curl_setopt($ch, CURLOPT_URL, &url);
                        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
                        //curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
                        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
                        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
                        curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
                        curl_setopt($ch, CURLOPT_POSTFIELDS, $XmlString);
                        ///////////////////////
                        $response = curl_exec($ch);

                curl_close($ch);

    $XmlString = simplexml_load_string($response);

            //create object to use as json
            $json = array();



                $json['redirect'] = $this->url->link('checkout/success', '', true);


            $this->response->addHeader('Content-Type: application/json');
            $this->response->setOutput(json_encode($json));

但这不起作用......伤心......我想念的是什么？

如何正确创建xml请求并将其发布到url？

Answer 1

您已经在评论中提供了一些提示（也许是您的答案），但这里有一些关于您应该如何改进代码并帮助其他人帮助您的想法。

PHP为您提供了一些创建XML的好资源，您应该使用它们。我推荐DOMDocument。以下是您的示例的入门代码。

$dom = new DOMDocument('1.0', 'utf-8');
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;

$namespace = 'http://e-credit.ubl.lt/eshop';
$contractRequest = $dom->createElement('ContractRequest');
$contractRequest->setAttributeNS('http://www.w3.org/2000/xmlns/', 'xmlns', $namespace);
$saleLogin = $dom->createElement('SaleLogin', 'test');
$saleConditionID = $dom->createElement('SaleConditionID', '111');

$contractRequest->appendChild($saleLogin);
$contractRequest->appendChild($saleConditionID);
$dom->appendChild($contractRequest);
//you got the idea...

对于卷曲部分，首先将第一个setopt更改为curl_setopt($ch, CURLOPT_URL, $url);。现在，在关闭curl句柄之前，插入以下代码：

if($response === false)
{
    echo 'Curl error: ' . curl_error($ch);
}

如果不起作用，您可以调试curl请求。这another question可能会对您有所帮助。

更新

我认为对你的请求使用curl是正确的选择，但是，正如你在评论中所要求的，如果你的curl请求仍然失败，这里有一个选项。

$payload = array();
$payload['header'] = 'Content-Type: text/xml';
$payload['header'] .= 'Content-Length: ' . strlen($XmlString);
$payload['content'] = is_array($XmlString) ? http_build_query($XmlString) : $XmlString;
$payload['method'] = 'POST';
$payloadContext =  stream_context_create(array('http' => $payload));
$result = file_get_contents($url, false, $payloadContext);
if ($result === false) {
  print_r ("Error in your request. Check logs for more information");
}

正如我所说，它只是一个选项，但卷曲仍然很好，你只需要纠正它。
