[[NSFont systemFontOfSize:13] fontDescriptor]我检查了这个代码10次（至少），但我不明白它为什么不创建<?php
ob_start();
session_start();
require ('openid.php');
function logout() {
echo '<form action="logout.php" method="post"><button class="btn btn-danger" type="submit"><i class="fa fa-power-off"></i> Log Out</button></form>'; //logout button
}
function steamlogin() {
try {
require("settings.php");
$openid = new LightOpenID($domain);
if(!$openid->mode) {
if(isset($_GET['login'])) {
$openid->identity = 'http://steamcommunity.com/openid';
header('Location: ' . $openid->authUrl());
}
return "<form action=\"?login\" method=\"post\"> <input type=\"image\" src=\"http://cdn.steamcommunity.com/public/images/signinthroughsteam/sits_large_noborder.png\"></form>";
}
elseif($openid->mode == 'cancel') {
echo 'User has canceled authentication!';
} else {
if($openid->validate()) {
$id = $openid->identity;
$ptn = "/^http:\/\/steamcommunity\.com\/openid\/id\/(7[0-9]{15,25}+)$/";
preg_match($ptn, $id, $matches);
$steamid = $matches[1];
$link = file_get_contents("http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=".$key."&steamids=".$steamid."");
$decode = json_decode($link);
$newlink = $decode->response->players->profileurl;
$xml = simplexml_load_file($newlink."?xml=1");
@$custom = $xml->customURL;
if(strlen($custom) <= 4){
$user = $xml->steamID64;
} else {
$user = $custom;
}
$_SESSION['steamid'] = $user;
//Determine the return to page. We substract "login&"" to remove the login var from the URL.
//"file.php?login&foo=bar" would become "file.php?foo=bar"
$returnTo = str_replace('login&', '', $_GET['openid_return_to']);
//If it didn't change anything, it means that there's no additionals vars, so remove the login var so that we don't get redirected to Steam over and over.
if($returnTo === $_GET['openid_return_to']) $returnTo = str_replace('?login', '', $_GET['openid_return_to']);
header('Location: '.$returnTo);

。你能救我吗？

答案 0 :(得分：0)
首先，你应该尝试设置虚拟数据来测试你的会话是否正常工作。在你的session_start()之后加上一行
$_SESSION['test'] = 'test';
var_dump($_SESSION);
如果密钥在整个请求中没有持久存在，则表示会话处理程序存在问题（可能缺少写入权限）。
如果您的会话正在运行，那么您开始沿着逻辑树开始，检查每个if语句中的表达式以查看执行路径是什么，您不提供任何当前输出，因此我无法立即告诉。
这不是一个明确的答案，但我相信如果你听从我的建议，你就会找到问题的根源。
