JSON Post in PHP（CSP-Report）

Question

今天我执行了Content-Security-Policy (CSP)。我还包括report-uri，因此它会发送一个POST请求到myserver.com/csp-report.php。由于MDN在其网站上解释的那样，POST请求是这样的：

{ 
    "csp-report": { 
    "document-uri": "http://example.com/signup.html", 
    "referrer": "http://evil.example.net/haxor.html", 
    "blocked-uri": "http://evil.example.net/injected.png", 
    "violated-directive": "img-src *.example.com", 
    "original-policy": "default-src 'self'; img-src 'self' *.example.com; report-uri /_/csp-reports", 
    } 
} 

我想通过电子邮件发送此信息，以reports@myserver.com。目前，我有这样的代码，但它只是邮件“阵列（）阵列（）”

<?php 
$tars = Array("reports@myserver.com", "webm@myserver.com"); 
$from = "notify@myserver.com"; 
$subject = "CSP Report"; 
$text = print_r($_POST, true); 
$text = (isSet($_GET["text"]) ? $_GET["text"] : $text); 
foreach($tars as $tar){ 
    $e = mail($tar,$subject,$text,"From: $from"); 
} 
if($e){ 
    header("Content-type: text/javascript"); 
    echo 'console.log("Email Sent");'; 
    exit(); 
} 
?>

<?php 
# 
# Set vars for mail sender and recipient 
$sender = $_SERVER['SERVER_ADMIN']; 
$recipient = $_SERVER['SERVER_ADMIN']; 
$subject = $_SERVER['SERVER_NAME'] . ' CSP Report'; 
$smtp_headers = 'From: ' . $_SERVER['SERVER_ADMIN'] . "\r\n" . 
    'Reply-To: ' . $_SERVER['SERVER_ADMIN'] . "\r\n" . 
    'X-Mailer: PHP/' . phpversion(); 
# 
# Get the report content 
$json = file_get_contents('php://input'); 
if ($json === false) { 
    throw new Exception('Bad Request'); 
} 
$message = 'The user agent "' . $_SERVER['HTTP_USER_AGENT'] . '" ' 
      . 'from ' . $_SERVER['REMOTE_HOST'] . ' ' 
      . '(IP ' . $_SERVER['REMOTE_ADDR'] . ') ' 
      . 'reported the following content security policy (CSP) violation:' . "\n\n"; 
$csp = json_decode($json, true); 
if (is_null($csp)) { 
    throw new Exception('Bad JSON Violation'); 
} 

# Parse 
foreach ($csp['csp-report'] as $key => $value) { 
    $message .= ' ' . $key . ": " . $value ."\n"; 
} 

# 
# Send the report 
$reported = mail($recipient, $subject, $message, $smtp_headers); 

# 
# Log in client? 
if ($reported) { 
    header("Content-type: text/javascript"); 
    echo 'console.log("Email Sent");'; 
    exit(); 
}
