我有一個小應用程序，現在是時候在所有內容中包含一個登錄遊戲。剛剛得到它，並在現實世界中運行（：P）設置cookie並且無法在不同的php文件中讀取它們
這是我的登錄頁面上的代碼（login.php中）：
<!DOCTYPE html>
<html>
<head>
<title>
Login
</title>
<meta charset="UTF-8">
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
</head>
<body>
<?php include_once("analyticstracking.php") ?>
<form action="login.php" method="POST">
<?php
if (isset($_POST['user']) && isset($_POST['password']))
{
if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response']))
{
$secret = '';
$verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response']);
$responseData = json_decode($verifyResponse);
if($responseData->success)
{
$user = $_POST['user'];
$password = $_POST['password'];
$salt = "d5f332312e3e390c81f6ef9f242c21bf9e472d6296ddd4bebddd0f54eb576f14";
$hpassword = hash('sha256', $salt . $password);
$_COOKIE['user'] = $user;
$_COOKIE['pass'] = $hpassword;
$auth = 1;
$_COOKIE['authorized'] = $auth;
setrawcookie("user", $user, time() + 28800, "/",'domaindig.eu');
setrawcookie("hpass", $hpassword, time() + 28800, "/",'domaindig.eu');
setrawcookie("authorized", $auth, time() + 28800, "/",'domaindig.eu');
print_r($_COOKIE);
header('Location: check.php');
}
}
}
?>
username: <input name="user" type="user"><br>
password: <input name="password" type="password"><br>
<div class="g-recaptcha" data-sitekey=""></div>
<input type="submit" value="Submit" /><br><br>
</form>
</body>
</html>
正如你可能會看到，我使用谷歌驗證碼我爲了防止暴力登錄。到那時（當我插入repcatcha時），我的$ _SESSION變量再也沒有工作過了。所以，我決定使用cookie（由於經常使用會話而引起的新嘗試）。
到目前爲止，這麼好。
當我完成了這個php頁面的編碼之後，我開始整理php文件check.php。在這個文件中，我檢查憑據，如果一切都檢出，我重定向到主頁面和菜單（沒有任何圖表是，只有純粹的PHP）。
我的問題是：
在第二個文件上，我看不到任何cookie。我使用print_r（$ _ COOKIE）;我只看到來自recaptcha的cookies。在登錄頁面上，我看到了3個我正在嘗試設置的cookie，但在其他文件中，似乎我無法讀取它們。我查了多個瀏覽器和多臺電腦，但運氣一樣。我已經確認，瀏覽器可以接受cookies，但似乎我犯了一個錯誤。
如果我的描述有些模糊，請告訴我，我會澄清。
這裏是我的check.php代碼（檢查使用cookie憑證）：
<!DOCTYPE html>
<html>
<head>
<title>
check
</title>
<meta charset="UTF-8">
</head>
<body>
<?php include_once("analyticstracking.php") ?>
<form action="check.php" method="POST">

這裏也是我的餅乾的照片時，我向他們展示登錄頁面：
我提前感謝大家。
所有文件，都在相同的域名，並在同一目錄（/） – adamkwn
我剛剛在我的主機上運行您的代碼，我可以得到cookies.Please確保您訪問在同一個域中的兩個php文件。 –
你好。這確實奏效，但如果你將上面的代碼與google recaptcha結合起來，會話不起作用，但我希望cookies能夠工作。你有沒有用recaptcha試過這段代碼？ – adamkwn
