【英文标题】：PayPal IPN simulator always giving INVALID response in PHP

【问题描述】：

我正在模拟沙盒购买，但我不断收到无效响应。

我在这里直接从 PayPal 获取了 IPN php 代码：https://github.com/paypal/ipn-code-samples

我已将 CURLOPT_SSL_VERIFYPEER 和 CURLOPT_SSL_VERIFYHOST 更改为 0，因为我没有运行 SSL 测试服务器，但即使像默认值一样将它们保留在 1 和 2 上，也不会改变任何内容：

<?php
define("DEBUG", 1);
define("USE_SANDBOX", 1);
define("LOG_FILE", "./ipn.log");
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) 
    $keyval = explode ('=', $keyval);
    if (count($keyval) == 2)
        $myPost[$keyval[0]] = urldecode($keyval[1]);

$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) 
    $get_magic_quotes_exists = true;

foreach ($myPost as $key => $value) 
    if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) 
        $value = urlencode(stripslashes($value));
     else 
        $value = urlencode($value);
    
    $req .= "&$key=$value";

if(USE_SANDBOX == true) 
    $paypal_url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
 else 
    $paypal_url = "https://www.paypal.com/cgi-bin/webscr";

$ch = curl_init($paypal_url);
if ($ch == FALSE) 
    return FALSE;

curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
if(DEBUG == true) 
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLINFO_HEADER_OUT, 1);

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
$res = curl_exec($ch);
if (curl_errno($ch) != 0) // cURL error
    
    if(DEBUG == true)  
        error_log(date('[Y-m-d H:i e] '). "Can't connect to PayPal to validate IPN message: " . curl_error($ch) . PHP_EOL, 3, LOG_FILE);
    
    curl_close($ch);
    exit;
 else 
        if(DEBUG == true) 
            error_log(date('[Y-m-d H:i e] '). "HTTP request of validation request:". curl_getinfo($ch, CURLINFO_HEADER_OUT) ." for IPN payload: $req" . PHP_EOL, 3, LOG_FILE);
            error_log(date('[Y-m-d H:i e] '). "HTTP response of validation request: $res" . PHP_EOL, 3, LOG_FILE);
        
        curl_close($ch);

$tokens = explode("\r\n\r\n", trim($res));
$res = trim(end($tokens));
if (strcmp ($res, "VERIFIED") == 0)    
    if(DEBUG == true) 
        error_log(date('[Y-m-d H:i e] '). "Verified IPN: $req ". PHP_EOL, 3, LOG_FILE);
    
 else if (strcmp ($res, "INVALID") == 0) 
    if(DEBUG == true) 
        error_log(date('[Y-m-d H:i e] '). "Invalid IPN: $req" . PHP_EOL, 3, LOG_FILE);
    

?>

日志文件中的结果：

【参考方案1】：

试试这个方法：

私有函数 PPHttpPost( $methodName_, $nvpStr_ ) $api_username = '[e-mail]'; $api_password = 'QWEQWEWQEQWEQEQWE';$api_signature = 'WQEQWEQWEQWEWQEQWEQWEQWEQWEQWE.cT';$api_endpoint = "https://api-3t.paypal.com/nvp";$version = '124.0' ; $ch = curl_init();curl_setopt($ch, CURLOPT_URL, $api_endpoint);curl_setopt($ch, CURLOPT_VERBOSE, 1);curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 1); $nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$api_password&USER=$api_username&SIGNATURE=$api_signature&$nvpStr_"; curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);$httpResponse = curl_exec($ch);if(!$httpResponse) exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');// 提取响应详细信息。 $httpResponseAr = explode("&", $httpResponse); $httpParsedResponseAr = array();foreach ($httpResponseAr as $i => $value) $tmpAr = explode("=", $value); if(sizeof($ tmpAr) > 1) $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1]; if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) exit("对 $api_endpoint 的 POST 请求 ($nvpreq) 的 HTTP 响应无效。"); 返回 $httpParsedResponseAr;

感谢您的建议！这么晚才回复很抱歉！我已经尝试过了，但它不起作用，我没有用这种方法得到任何响应。在我的一切工作除了“无效”部分
