Java Android Studio登录创建帐户

我在YouTube上学习了一个教程，但我只输入了登录名和创建帐户部分

所以我的问题是，我的程序没有错误，但我无法将新数据插入数据库。我使用wamp作为我的服务器。下面是我向数据库发送请求的类

这是我的php文件

<?php

    $con=mysqli_connect("localhost", "root","","seniorproject");

    $name = $_POST["name"];
    $account = $_POST["account"];
    $password = $_POST["password"];
    $phone = $_POST["phone"];
    $department = $_POST["department"];

    $statement = mysqli_prepare($con, "INSERT INTO User (name, account, password, phone, department) VALUES(?, ?, ?, ?, ?) ");
    mysqli_stmt_bind_param($statement, "sssss", $name , $account, $password, $phone, $department );
    mysqli_stmt_execute($statement);

    mysqli_stmt_close($statement);


    mysqli_close($con);
?>

这是我在emulator中按create account后的日志，确认192.168.0.2实际上是ip地址，因为错误消息清楚地报告了尝试连接到该端点的超时。

您的问题是什么。你有没有收到错误？没有，我没有收到任何错误，但当我单击“创建帐户”时，数据库从未插入任何数据，所以我想知道发生了什么错误，你必须一步一步地检查，问题出在哪里。检查您的php代码。它能工作吗？谢谢我检查了我的IP地址好几次它能工作你能用chrome从设备上打开php脚本吗？如果失败，则设备使用的LAN、子网、网关地址上存在DNS问题。

<?php

    $con=mysqli_connect("localhost", "root","","seniorproject");

    $name = $_POST["name"];
    $account = $_POST["account"];
    $password = $_POST["password"];
    $phone = $_POST["phone"];
    $department = $_POST["department"];

    $statement = mysqli_prepare($con, "INSERT INTO User (name, account, password, phone, department) VALUES(?, ?, ?, ?, ?) ");
    mysqli_stmt_bind_param($statement, "sssss", $name , $account, $password, $phone, $department );
    mysqli_stmt_execute($statement);

    mysqli_stmt_close($statement);


    mysqli_close($con);
?>
