Java Post Data请求返回HTTP响应代码500

我正在使用Java中的一个程序，该程序需要用户登录，但是何时结束HTTP请求并尝试读取输出，它返回HTTP响应代码500。

plogin.php中的代码如下：

    if(isset($_POST['redir'])){
        $redir = $_POST['redir'];
    }else{
        $redir = '';
    }
    $query = $conn->prepare("SELECT Password, Verified, Admin FROM Users WHERE Name=?");
    $query->bind_param('s', $user);
    if($query->execute()){
        $query->bind_result($hash, $ver, $admin);
        while($query->fetch()){
            if($ver == "T"){
                if($query->num_rows > 0){
                    if(validate_password($password, $hash)){
                        $_SESSION['user'] = $user;
                        $msg = session_id() . ':' . $user;
                    }else{
                        $msg = 'Incorrect username or password';
                    }
                }else{
                    $msg = 'Incorrect username or password';
                }
            }else{
                $msg = 'Your account has not been verified, please check your email and do so now if you wish to continue.';
            }
            }
    }else{

    }

预先感谢您，希望您能为我提供帮助：）

编辑：我知道Conn.php或hash.php中不是错误

编辑：stacktrace：

我遇到了相同的问题，现在解决了。只需检查正确的编码即可。确保您已将所有内容编码为同一charset。就我而言，我正在使用ISO8859_1编码。服务器对Firefox浏览器的响应正常，但错误500对我的Java程序。我更改为ISO8859_1，现在正在工作：

    public void sendPost(String Url, String params) throws Exception {

    String url=Url;
    URL obj = new URL(url);
    HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
    con.setRequestProperty("Acceptcharset", "en-us");
    con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
    con.setRequestProperty("charset", "EN-US");
    con.setRequestProperty("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
    String urlParameters=params;
    // Send post request
    con.setDoOutput(true);
    con.setDoInput(true);
    con.connect();
    //con.
    DataOutputStream wr = new DataOutputStream(con.getOutputStream());
    wr.writeBytes(urlParameters);
    wr.flush();
    wr.close();
    int responseCode = con.getResponseCode();
    System.out.println("nSending 'POST' request to URL : " + url);
    System.out.println("Post parameters : " + urlParameters);
    System.out.println("Response Code : " + responseCode);
    BufferedReader in = new BufferedReader(
            new InputStreamReader(con.getInputStream()));
    String inputLine;
    StringBuffer response = new StringBuffer();
    while ((inputLine = in.readLine()) != null) {
        response.append(inputLine);
    }
    in.close();
    //print result
    System.out.println(response.toString());
    this.response=response.toString();
    con.disconnect();
}

在主要程序中，我这样称呼为：

    certcon.sendPost("https://www.desphilboy.com/authbox/generateCRT","csr_string="+URLEncoder.encode(requestparams,"ISO8859_1"));
