在fsockopen的情况下发布数据，接收方未收到任何数据

我使用fsockopen连接并向脚本发送数据。问题是接收端没有接收到任何数据，正如您在下面的输出中看到的那样，只打印了空数组。我的解决方案基于Tamlyns的答案：使用Fsockopen发布PHP数据。我确实尝试了他创建post参数的方法，输出没有差异。

我的主脚本：

<?php
session_start();  
    $fp = fsockopen("192.168.1.107",    
          80,
          $errno, $errstr, 10);    
    $params = "smtp=posteddata'r'n";
    $params = urlencode($params);
    $auth = base64_encode("kaand:kaand123");
     if (!$fp) {
          return false;
      } else {
          error_log("4");
          $out = "POST /smic/testarea/fsockopen_print_post.php HTTP/1.1'r'n";      
          $out.= "Host: 192.168.1.107'r'n";      
          $out.= "Content-Type: application/x-www-form-urlencoded'r'n";
          $out.= "Authorization: Basic ".$auth;
          $out.= 'Content-Length: '.strlen($params).''r'n';
          $out.= "Connection: Close'r'n'r'n";
          $out .= $params;
          fwrite($fp, $out);
          fflush($fp);
          header('Content-type: text/plain');
          while (!feof($fp)) {
                echo fgets($fp, 1024);
            }
          fclose($fp);
      }        
?>

fsockopen_print_post.php：

<?php
session_start();
print_r($_POST);
$raw_data = $GLOBALS['HTTP_RAW_POST_DATA'];  
parse_str( $raw_data, $_POST );
print_r($_POST);
?>

输出：

问题出在哪里？我该如何解决？
