GET 方法会导致错误

对不起标题，但我不确定如何称呼它。

我已注册到 ssm 服务，该服务可以使用 php 脚本发送自动短信。该脚本基本上构建了一个包含所有 SMS 参数（发件人名称，..）的 XML 字符串。

然后它使用它来发送它：

$sms_host = "api.inforu.co.il"; // Application server's URL;  
    $sms_port = 80; // Application server's PORT; 
    ////.... generating query 
    $sms_path = "/SendMessageXml.ashx"; // Application server's PATH; 
    $fp = fsockopen($sms_host, $sms_port, $errno, $errstr, 30); // Opens a socket to the Application server
    if (!$fp){ // Verifies that the socket has been opened and sending the message; 
        echo "$errstr ($errno)<br />'n"; 
        echo "no error";
    } else  {
        $out = "GET $sms_path?$query HTTP/1.1'r'n";
        $out .= "Host: $sms_host'r'n";
        $out .= "Connection: Close'r'n'r'n";
        fwrite($fp, $out);
        while (!feof($fp)){ 
            echo fgets($fp, 128); 
        } 
        fclose($fp); 

如果我粘贴这个，查询很好

$url = "http://api.inforu.co.il/SendMessageXml.ashx?" . $query;

直接在浏览器中，然后发送短信。

所以问题是我收到错误

"/"应用程序中的服务器错误。
