php - 使用 PHP、MySQL 和 SQLite 登录和注册

Question

我正在练习在移动应用程序中开发登录和注册，但也集成在网络应用程序中，所以我正在关注这个:http://www.androidhive.info/2012/01/android-login-and-registration-with-php-mysql-and-sqlite/

但是当在本地主机上运行时，输出显示:

{"error":true,"error_msg":"Required parameters (name, email or password) is missing!"}

这是源代码:

// json response array
$response = array("error" => FALSE);

if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['password'])) {

// receiving the post params
$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];

// check if user is already existed with the same email
if ($db->isUserExisted($email)) {
    // user already existed
    $response["error"] = TRUE;
    $response["error_msg"] = "User already existed with " . $email;
    echo json_encode($response);
} else {
    // create a new user
    $user = $db->storeUser($name, $email, $password);
    if ($user) {
        // user stored successfully
        $response["error"] = FALSE;
        $response["uid"] = $user["unique_id"];
        $response["user"]["name"] = $user["name"];
        $response["user"]["email"] = $user["email"];
        $response["user"]["created_at"] = $user["created_at"];
        $response["user"]["updated_at"] = $user["updated_at"];
        echo json_encode($response);
    } else {
        // user failed to store
        $response["error"] = TRUE;
        $response["error_msg"] = "Unknown error occurred in registration!";
        echo json_encode($response);
    }   
    }
}
else {
$response["error"] = TRUE;
$response["error_msg"] = "Required parameters (name, email or password) is missing!";
echo json_encode($response);
}
?>

使用此代码登录

<?php
//response array
$response = array("error" => FALSE);
if (isset($_POST['btn_name'])) 
{
// receiving the post params
$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];
    if($name!="" && $email!="" && $password!="")
    {
        // check if user is already existed with the same email
        if ($db->isUserExisted($email)) {
            // user already existed
            $response["error"] = TRUE;
            $response["error_msg"] = "User already existed with " . $email;
            echo json_encode($response);
        } else {
            // create a new user
            $user = $db->storeUser($name, $email, $password);
            if ($user) {
                // user stored successfully
                $response["error"] = FALSE;
                $response["uid"] = $user["unique_id"];
                $response["user"]["name"] = $user["name"];
                $response["user"]["email"] = $user["email"];
                $response["user"]["created_at"] = $user["created_at"];
                $response["user"]["updated_at"] = $user["updated_at"];
                echo json_encode($response);
            } else {
                // user failed to store
                $response["error"] = TRUE;
                $response["error_msg"] = "Unknown error occurred in registration!";
                echo json_encode($response);
            }   
        }
    }
    else {
    $response["error"] = TRUE;
    $response["error_msg"] = "Required parameters (name, email or password) is missing!";
    echo json_encode($response);
    }
}
