我使用 PHP 在 MySQL 中创建了数据库。我有 registration.php 文件。从 Android 应用程序插入数据时会引发错误。
这是我的 registration.php:
<?php
// array for JSON response
$response = array();
// check for required fields
if (isset($_POST['fname']) && isset($_POST['lname']) && sisset($_POST['email']) && isset($_POST['phone']) && isset($_POST['password']))
{
$fname = $_GET['fname'];
$lname = $_GET['lname'];
$email = $_GET['email'];
$phone = $_GET['phone'];
$password = $_GET['password'];
// include db connect class
require_once __DIR__ . '/db_connect.php';
//include("db_connect.php");
// connecting to db
$db = new DB_CONNECT();
// mysql inserting a new row
$result = mysql_query("INSERT INTO user_master(fname, lname, email, phone, password,) VALUES ('$fname','$lname', '$email','$phone','$password',)");
// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["success"] = 1;
$response["message"] = "**successfully Registration.**";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["success"] = 0;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
} else {
// required field is missing
$response["success"] = 0;
$response["message"] = "Required field(s) is missing";
// echoing JSON response
echo json_encode($response);
}
?>
这是我的 Registration.java 文件:
public class Registartion extends Activity implements OnClickListener {

您没有正确构建 JSON 结构。您确实需要使用像 Gson 这样的 JSON 库来将您的数据序列化/反序列化为 JSON。
