我想通过点击为会话赋值
我试图这样做,但它不起作用:
<?php session_start();
$_SESSION['role']="";?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

<title></title>
<link href="auth-buttons.css" rel="stylesheet" />
<link href="StyleSheet.css" rel="stylesheet" />
</head>
<body>
<div id="wrap">
<div id="wrapHome">
<p><a class="btn-auth btn-facebook large" href="redirect.php" onclick="<?php $_SESSION['role']="facebook" ?>" > Sign in with <b>Facebook</b> </a></p>
<p><a class="btn-auth btn-twitter large" href="redirect.php" onclick="<?php $_SESSION['role']="twitter" ?>" > Sign in with <b>Twitter</b> </a></p>
<p><a class="btn-auth btn-google large" href="redirect.php" onclick="<?php $_SESSION['role']="google" ?>" > Sign in with <b>Google</b> </a></p>
</div>
</div>

我正在使用ebay-api用于node-js,当我因某种原因刷新页面时出现错误.在控制台日志中,我收到"无法在发送后发送标头"的错误.这是我的代码,你可以弄清楚为什么我在刷新时"在发送后发送标题"？
