Question

我想从我的数据库中的表中获取一个特定的行，即只有与登录用户相关的行。我正在使用以下脚本：

<?php
 include('./classes/DB.php');
 include('./classes/Login.php');

$connect = mysqli_connect("localhost", "root", "", "gaming");  
$playerid = Login::isLoggedIn();

$sql = "SELECT * FROM games";// WHERE player_id =" .$playerid;  
$result = mysqli_query($connect, $sql);  
$json_array = array();  

while($row = mysqli_fetch_assoc($result))  
    {  
        if ($row['player_id']==$playerid) {
            $json_array[] = $row;  
        }
   }  

echo json_encode($json_array); 
?>

Login.php：

<?php 

class Login {

public static function isLoggedIn() {

    if (isset($_COOKIE['CHEZA'])) {
        if (DB::query('SELECT user_id FROM login_tokens WHERE token=:token',    array(':token'=>sha1($_COOKIE['CHEZA'])))) {
            $userid = DB::query('SELECT user_id FROM login_tokens WHERE token=:token', array(':token'=>sha1($_COOKIE['CHEZA'])))[0]['user_id'];
            if (isset($_COOKIE['CHEZACHEZA'])) {
                    return $userid;
            } else {
                $cstrong = True;
                $token = bin2hex(openssl_random_pseudo_bytes(64, $cstrong));
                DB::query('INSERT INTO login_tokens VALUES (\'\', :token, :user_id)', array(':token'=>sha1($token), ':user_id'=>$userid));
                DB::query('DELETE FROM login_tokens WHERE token=:token', array(':token'=>sha1($_COOKIE['CHEZA'])));
                setcookie("CHEZA", $token, time() + 60 * 60 * 24 * 7, '/', NULL, NULL, TRUE);
                setcookie("CHEZACHEZA", '1', time() + 60 * 60 * 24 * 3, '/', NULL, NULL, TRUE);
                return $userid;
            }
        }
    }
    return false;
}
}
?>

我在浏览器中得到了所需的响应但是当我使用REST客户端时，我得到的是一个空数组[]。我做错了什么？

Answer 1

$playerid = Login::isLoggedIn();

未设置，请检查。

修改

现在发布了isLoggedIn()的代码：您确定您的REST客户端正在发送CHEZA cookie吗？我不认为在REST调用中使用cookie是个好主意。我发现这篇阅读很有用：https://softwareengineering.stackexchange.com/questions/141019/should-cookies-be-used-in-a-restful-api

Answer 2

尝试修改您的PHP代码，我在运行您的查询和逻辑代码之前添加了 isset 检查：

print_r($playerid)

如果它不起作用，请尝试添加=IF(B2<>"",B2*C2,IF(D2<>"",D2*E2))并检查您是否获得 loggedin 用户ID。

获取mysql中的特定行
