define('QQ_APPID','102468789');//appkey
define('QQ_APPSECRET','914bf642u54fc9181cc695bc1f43f5');//appsecret
define('QQ_REDIRECT_URI','http://www.zhaoyoucai.com/mp/auth-qq.php');//redirect_uri

function fa_qq_oauth_redirect(){
    echo '<script>if (window.opener) {
    window.opener.location.reload();
    window.close()
} else {
    window.location.href = "'.$_SESSION['prevUrl'].'"
}</script>';
}

function qq_oauth(){
//略去验证过程

//成功后跳转
fa_qq_oauth_redirect();

}

function qq_oauth_url(){
    $url = "https://graph.qq.com/oauth2.0/authorize?client_id=" . QQ_APPID . "&state=" . md5 ( uniqid ( rand (), true ) ) . "&response_type=code&redirect_uri=" . urlencode (QQ_REDIRECT_URI);
    //return $url;
    echo "<script language='javascript' type='text/javascript'>";  
    echo "window.location.href='$url'";  
    echo "</script>";
    
}
if (isset($_GET ['state']) && isset($_GET ['code'])) qq_oauth();
if (isset($_GET ['showurl']) ){
    if($_GET ['showurl']!=''){
        $_SESSION['prevUrl'] = $_GET ['showurl'];
    }else{
        if(isset($_SERVER['HTTP_REFERER'])) {
            $_SESSION['prevUrl'] = $_SERVER['HTTP_REFERER'];
        }else{
            $_SESSION['prevUrl'] = home_url();
        }
    }
    
    qq_oauth_url();
}
