如何在返回标头时解析curl响应

Question

所以我想要做的是解析响应中的每个“节点”，因为缺少更好的单词。它应该回显“标签”，然后是“：”然后是值。我试过的是“代码”部分。从当前代码返回的内容位于“响应”部分。我正在尝试从其他代码中学习，这是“用于调试和认证目的的显示标题/正文/响应”代码的来源。我只是试图修改它以回应解析后的rawResponse，当它显然没有。

的响应：

    headers:
    body:
    rawResponse:AC700000005332001VI4788250000028291sBn551664C1A088C3242DF9CD5C92D52A8FA9EDD532D10100 N097857Approved00N013731
    OrderID: sBn5
    TxRefNum: 51664C1A088C3242DF9CD5C92D52A8FA9EDD532D
    RespCode: 00
    AVSRespCode: 
    CVV2RespCode: N
    AuthCode: 097857

的代码：

<?php

$xml_data = "<Request><NewOrder>";
$xml_data .= "<IndustryType>EC</IndustryType>";
$xml_data .= "<MessageType>AC</MessageType>";
$xml_data .= "<BIN>000002</BIN>";
$xml_data .= "<AccountNum>".$varCC."</AccountNum>";
$xml_data .= "<Exp>".$varExpiry."</Exp>";
$xml_data .= "<CardSecVal>".$varCVV."</CardSecVal>";
$xml_data .= "<OrderID>sBn5</OrderID>";
$xml_data .= "<Amount>".$varAmt."</Amount>";
$xml_data .= "</NewOrder></Request>";   

$URL = "https://orbitalvar1.paymentech.net";

// Build header as array for cURL option
$header = "POST /AUTHORIZE HTTP/1.0\r\n";
$header.= "MIME-Version: 1.0\r\n";
$header.= "Content-type: application/PTI46\r\n";
$header.= "Content-length: ".strlen($xml_data)."\r\n";
$header.= "Content-transfer-encoding: text\r\n";
$header.= "Request-number: 1\r\n";
$header.= "Document-type: Request\r\n";
$header.= "Interface-Version: Test 1.4\r\n";
$header.= "Connection: close \r\n\r\n";              
$header.= $xml_data;   

// Define cURL options, then connect to server while saving response
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,$URL);

curl_setopt($ch, CURLOPT_HEADER, false); 
curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$rawResponse = curl_exec($ch);             

if (curl_errno($ch)) {
   print curl_error($ch);
} else {
   curl_close($ch);
}

Answer 1

你需要从http正文中单独的http标题。这是一个"\r\n\r\n" snting。所以你可以这样找到它：

$p = strpos($rawResponse, "\r\n\r\n");
if( $p !== false ) {
    $rawHeades = substr($rawResponse, 0, $p);
    $rawBody = substr($rawResponse, $p + 4);
}

你需要print curl_error($ch);之后的一些东西 - 在这种情况下，$ rawResponse中没有任何真实的数据
