Question

我正在创建一个Android项目，其中Registrationadmin活动使用HttpURLConnection连接到PHP文件（在本地服务器中，localhost）;

我遇到以下代码行的问题： InputStream = httpURLConnection.getInputStream（）; 当我运行项目时，应用程序此时停止，它还提供D / NetworkSecurityConfig：未指定Network Security Config，使用平台默认此错误

问题出在哪里？

我在这里报告代码部分：

<?php
echo "this is it";
error_reporting(0);
require "init.php";
$admname = $_POST["admname"];
$admpass = $_POST["admpass"];
$admemail = $_POST["admemail"];
$admmob=$_POST["admmob"];
//$admname = "sdf";
//$admpassword = "sdf";
//$admemail = "sdf@r54";
//$admmob="sdf";
$sql = "INSERT INTO `admin` (`admname`,`admemail`, `admpass`, `admmob`) 
VALUES ('".$admname."','".$admemail."' '".$admpass."', '".$admmob."');";
if(!mysqli_query($con, $sql)){
    echo '{"message":"Unable to save the data to the database."}';
}
?>

register.php是

<?php
echo "this is init";
error_reporting(0);

$db_name = "mydata";
$mysql_user = "root";
$mysql_pass = "";
$server_name = "localhost";

$con = mysqli_connect($server_name, $mysql_user, $mysql_pass, $db_name);

if(!$con){
    echo '{"message":"Unable to connect to the database."}';
}

?>

，init.php是
