Curl 和 Sagepay

Question

我在将 Sagepay InFrame Server 与 PHP 集成时遇到了很多麻烦，因为没有可用于新协议 (v3) 的集成工具包。我有 v2.23 的旧工具包，但其中的大部分代码已被弃用。

目前，我成功从 Sagepay 服务器服务器检索 OK 状态的唯一方法是拥有一个表单，其中包含 Sagepay 所需的隐藏值集合，包括加密字段，并使用服务器 URL 作为形成动作。这在浏览器选项卡中为我提供了“OK”状态和 SecurityKey 等，但它在浏览器选项卡中没有多大用处，因为我需要在我的服务器上返回 POST 响应，而不是在他们的服务器上。

为此，我选择了 curl。我将 curl_exec 的返回值保存在一个名为 $rawresponse 的变量中，并在每次尝试后转储响应，就目前而言，$rawresponse 以虚假布尔值的形式返回：

$curlSession = curl_init();

curl_setopt ($curlSession, CURLOPT_URL, $url);
curl_setopt ($curlSession, CURLOPT_HEADER, 0);
curl_setopt ($curlSession, CURLOPT_POST, 1);
$data['Crypt'] = new CurlFile('filename.png', 'image/png', 'filename.png');
curl_setopt ($curlSession, CURLOPT_POSTFIELDS, $data);
curl_setopt($curlSession, CURLOPT_RETURNTRANSFER,1); 
curl_setopt($curlSession, CURLOPT_TIMEOUT,30); 
curl_setopt($curlSession, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curlSession, CURLOPT_SSL_VERIFYHOST, 0);

$rawresponse = curl_exec($curlSession);

现在你可以在这里看到，我必须强制 Crypt 值是 CurlFile 类型，我认为这会破坏请求，但是如果我不这样做，我会收到以下错误：

“不推荐使用@filename API 进行文件上传。请改用CURLFile 类”

我只能从中确定加密被误认为是文件（可能是因为字符串以 @ 开头），并且为了应对这种情况，我试图将其强制为图像。

所以我的问题是 - 有没有一种特殊的方式来使用 CurlFile 以便可以理解加密字符串？有没有更好的方法将此功能与任何人都知道的 Sagepay 集成？这确实是一个非常令人困惑的系统，而且由于完全缺乏示例而使良好的文档失望。

为此道歉，我以错误的方式构建字符串。以防万一将来有人遇到类似问题，我将粘贴适合我的代码：

public function registerTransaction()
{
    $VPSProtocol = urlencode($_POST['VPSProtocol']);
    $TxType = urlencode($_POST['TxType']);
    $Vendor = urlencode($_POST['Vendor']);
    $VendorTxCode = urlencode($_POST['VendorTxCode']);
    $Currency = urlencode($_POST['Currency']);
    $Amount = urlencode($_POST['Amount']);
    $NotificationURL = urlencode($_POST['NotificationURL']);
    $Description = urlencode($_POST['Description']);
    $BillingSurname = urlencode($_POST['BillingSurname']);
    $BillingFirstnames = urlencode($_POST['BillingFirstnames']);
    $BillingAddress1 = urlencode($_POST['BillingAddress1']);
    $BillingCity = urlencode($_POST['BillingCity']);
    $BillingPostCode = urlencode($_POST['BillingPostCode']);
    $BillingCountry = urlencode($_POST['BillingCountry']);
    $DeliverySurname = urlencode($_POST['DeliverySurname']);
    $DeliveryFirstnames = urlencode($_POST['DeliveryFirstnames']);
    $DeliveryAddress1 = urlencode($_POST['DeliveryAddress1']);
    $DeliveryCity = urlencode($_POST['DeliveryCity']);
    $DeliveryPostCode = urlencode($_POST['DeliveryPostCode']);
    $DeliveryCountry = urlencode($_POST['DeliveryCountry']);

    $url = "?VPSProtocol=" . $VPSProtocol;
    $url .= "&TxType=" . $TxType;
    $url .= "&Vendor=" . $Vendor;
    $url .= "&VendorTxCode=" . $VendorTxCode;
    $url .= "&Currency=" . $Currency;
    $url .= "&Amount=" . $Amount;
    $url .= "&NotificationURL=" . $NotificationURL;
    $url .= "&Description=" . $Description;
    $url .= "&BillingSurname=" . $BillingSurname;
    $url .= "&BillingFirstnames=" . $BillingFirstnames;
    $url .= "&BillingAddress1=" . $BillingAddress1;
    $url .= "&BillingCity=" . $BillingCity;
    $url .= "&BillingPostCode=" . $BillingPostCode;
    $url .= "&BillingCountry=" . $BillingCountry;
    $url .= "&DeliverySurname=" . $DeliverySurname;
    $url .= "&DeliveryFirstnames=" . $DeliveryFirstnames;
    $url .= "&DeliveryAddress1=" . $DeliveryAddress1;
    $url .= "&DeliveryCity=" . $DeliveryCity;
    $url .= "&DeliveryPostCode=" . $DeliveryPostCode;
    $url .= "&DeliveryCountry=" . $DeliveryCountry;

    $strPurchaseURL = "https://test.sagepay.com/gateway/service/vspserver-register.vsp";
    $arrResponse = $this->requestPost($strPurchaseURL, $url);
    dd($arrResponse);
}


public function requestPost($url, $data){
    // Set a one-minute timeout for this script
    set_time_limit(60);

    // Initialise output variable
    $output = array();

    // Open the cURL session
    $curlSession = curl_init();

    curl_setopt ($curlSession, CURLOPT_URL, $url);
    curl_setopt ($curlSession, CURLOPT_HEADER, 0);
    curl_setopt ($curlSession, CURLOPT_POST, 1);
    curl_setopt ($curlSession, CURLOPT_POSTFIELDS, $data);
    curl_setopt($curlSession, CURLOPT_RETURNTRANSFER,1); 
    curl_setopt($curlSession, CURLOPT_TIMEOUT,30); 
    curl_setopt($curlSession, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curlSession, CURLOPT_SSL_VERIFYHOST, 2);

    $rawresponse = curl_exec($curlSession);
    dd($rawresponse);
    //Store the raw response for later as it's useful to see for integration and understanding 
    $_SESSION["rawresponse"]=$rawresponse;
    //Split response into name=value pairs
    $response = preg_split(chr(10), $rawresponse);
    // Check that a connection was made
    if (curl_error($curlSession)){
        // If it wasn't...
        $output['Status'] = "FAIL";
        $output['StatusDetail'] = curl_error($curlSession);
    }

    // Close the cURL session
    curl_close ($curlSession);

    // Tokenise the response
    for ($i=0; $i<count($response); $i++){
        // Find position of first "=" character
        $splitAt = strpos($response[$i], "=");
        // Create an associative (hash) array with key/value pairs ('trim' strips excess whitespace)
        $output[trim(substr($response[$i], 0, $splitAt))] = trim(substr($response[$i], ($splitAt+1)));
    } // END for ($i=0; $i<count($response); $i++)

    // Return the output
    return $output;
} // END function requestPost()
