如何使用HttpPost类将数据从android发送到mysql？

问题描述 投票：0回答：1

我想用android做一个简单的游戏。我已经做了一个注册页面。我想将用户名和密码传输到mysql服务器。我尝试通过使用HttpPost类将发布请求发送到http://peeyshapps.epizy.com/add_entry.php来完成此操作，但是它不起作用，我的数据库中没有任何条目。我该如何解决？预先感谢。

add_entry.php包含：


<?php
    $response=array();
    $User=$_REQUEST["User"];
    $pass=$_REQUEST["Pass"];
    $conn=mysqli_connect("sql304.epizy.com","my_username","my_password","epiz_25639733_PWord") or die("SERVER ERROR!<br>ERR_Connection");
    $result=mysqli_query($conn,"INSERT INTO `Users`(`User`, `Password`) VALUES (\"$User\",\"$pass\")");
    if($result)
        $response[status]=1;
    else
        $response[status]=0;
    echo json_encode($response);
 ?>

用于注册的xml文件页面包含：

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"
    android:layout_height="match_parent"

尝试更改PHP以显示一些错误并检查是否返回任何内容：

$response=array();
$User=$_REQUEST["User"];
$pass=$_REQUEST["Pass"];
$conn=mysqli_connect("sql304.epizy.com","my_username","my_password","epiz_25639733_PWord") or die("SERVER ERROR!<br>ERR_Connection");

if(!$conn){
    $response["mysqliError"] = mysqli_connect_errno() . ": " . mysqli_connect_error();
}

$result=mysqli_query($conn,"INSERT INTO `Users`(`User`, `Password`) VALUES (\"$User\",\"$pass\")");
if($result)
    $response["status"]=1;
else
    $response["mysqliError"] = mysqli_errno($conn) . ": " . mysqli_error($conn);
    $response["status"]=0;
echo json_encode($response);

我这里没有PHP IDE，因此无法测试代码。可能会错过某些语法或类似内容
