Php 登录时无法获得显示头像的Steam API

我使用本教程为我正在创建的网站实现了steam登录：。问题是，当我登录时，它不显示任何信息，只显示一个注销按钮。这是我正在处理的代码

if(isset($_SESSION['steamid'])){

    include("settings.php");
    if (empty($_SESSION['steam_uptodate']) or $_SESSION['steam_uptodate'] == false or empty($_SESSION['steam_personaname'])) {
        //We mute alerts from the following line because we do not want to give away our API key in case file_get_contents() throws a warning.
        @ $url = file_get_contents("http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key=".$steamauth['apikey']."&steamids=".$_SESSION['steamid']);
        if($url === FALSE) { die('Error: failed to fetch content form Steam. It may be down. Please, try again later.'); }
        $content = json_decode($url, true);
        $_SESSION['steam_steamid'] = $content['response']['players'][0]['steamid'];
        $_SESSION['steam_communityvisibilitystate'] = $content['response']['players'][0]['communityvisibilitystate'];
        $_SESSION['steam_profilestate'] = $content['response']['players'][0]['profilestate'];
        $_SESSION['steam_personaname'] = $content['response']['players'][0]['personaname'];
        $_SESSION['steam_lastlogoff'] = $content['response']['players'][0]['lastlogoff'];
        $_SESSION['steam_profileurl'] = $content['response']['players'][0]['profileurl'];
        $_SESSION['steam_avatar'] = $content['response']['players'][0]['avatar'];
        $_SESSION['steam_avatarmedium'] = $content['response']['players'][0]['avatarmedium'];
        $_SESSION['steam_avatarfull'] = $content['response']['players'][0]['avatarfull'];
        $_SESSION['steam_personastate'] = $content['response']['players'][0]['personastate'];
        if (isset($content['response']['players'][0]['realname'])) { 
               $_SESSION['steam_realname'] = $content['response']['players'][0]['realname'];
           } else {
               $_SESSION['steam_realname'] = "Real name not given";
        }
        $_SESSION['steam_primaryclanid'] = $content['response']['players'][0]['primaryclanid'];
        $_SESSION['steam_timecreated'] = $content['response']['players'][0]['timecreated'];
        $_SESSION['steam_uptodate'] = true;
    }

    $steamprofile['steamid'] = $_SESSION['steam_steamid'];
    $steamprofile['communityvisibilitystate'] = $_SESSION['steam_communityvisibilitystate'];
    $steamprofile['profilestate'] = $_SESSION['steam_profilestate'];
    $steamprofile['personaname'] = $_SESSION['steam_personaname'];
    $steamprofile['lastlogoff'] = $_SESSION['steam_lastlogoff'];
    $steamprofile['profileurl'] = $_SESSION['steam_profileurl'];
    $steamprofile['avatar'] = $_SESSION['steam_avatar'];
    $steamprofile['avatarmedium'] = $_SESSION['steam_avatarmedium'];
    $steamprofile['avatarfull'] = $_SESSION['steam_avatarfull'];
    $steamprofile['personastate'] = $_SESSION['steam_personastate'];
    $steamprofile['realname'] = $_SESSION['steam_realname'];
    $steamprofile['primaryclanid'] = $_SESSION['steam_primaryclanid'];
    $steamprofile['timecreated'] = $_SESSION['steam_timecreated'];

}

我想做的是，当有人登录时，在登录按钮所在的位置，我想显示steam名称以及登录者的头像。

您看过文档了吗？要显示化身，请执行以下操作：

$steamprofile['avatar'] //  32x32 version of avatar
$steamprofile['avatarmedium'] // 64x64 version of avatar
$steamprofile['avatarfull'] // 184x184 version of avatar

$steamprofile['personaname']

要显示Steam用户名，请执行以下操作：

$steamprofile['avatar'] //  32x32 version of avatar
$steamprofile['avatarmedium'] // 64x64 version of avatar
$steamprofile['avatarfull'] // 184x184 version of avatar

$steamprofile['personaname']

它都写在底部的

README.md

文件中

编辑：如果要显示图像，请执行以下操作：

echo '<img src="' . $steamprofile['avatar'] . '" />';

echo'；

---

这将把

$steamprofile['avatar']

中的图像URL放入

元素。

您的程序中没有回显或打印任何内容。关于

@

这一行：如果您的用户可以看到PHP输出的警告，那么暴露您的API密钥应该是您最不担心的事情。我对PHP有非常基本的了解，我所困惑的是把$steamprofile['avatar']放在哪里，它会返回一个图像URL。如果要显示图像，请选中“我的编辑”。
