discuz登陆相关

$usename = "kkkkkkk" ;
$password = "123456" ;
$result = userlogin($usename, $password, null, null, "username", $_G["clientip"]);
//$result["status"] > 0 代表账号密码正确
$uid = $result["ucresult"]["uid"];

require libfile("function/member");
$result["member"] = getuserbyuid(1);
setloginstatus($result["member"], 2592000); //记录登陆状态保存在cookie或session中

账号密码验证正确,调用setloginstatus就能设置登陆状态了

验证密码是检验pre_ucenter_members表中的password,而不是pre_common_member中的password

密码验证方式  md5(md5(用户输入).salt) 是否中pre_ucenter_members.password是否一致

salt在pre_ucenter_members表中的salt字段

$auth =  authcode("{$member["password"]}	{$member["uid"]}", "ENCODE") ;
dsetcookie("auth",$auth, $cookietime, 1, true);

setloginstatus会把password和uid加密后，放在cookie中，用于在discuz_application中判断用户是否已经登陆

如以下代码

if($auth = getglobal("auth", "cookie")) {
	$auth = daddslashes(explode("	", authcode($auth, "DECODE")));
}
list($discuz_pw, $discuz_uid) = empty($auth) || count($auth) < 2 ? array("", "") : $auth;

if($discuz_uid) {
	$user = getuserbyuid($discuz_uid, 1);
}

if(!empty($user) && $user["password"] == $discuz_pw) {
	if(isset($user["_inarchive"])) {
		C::t("common_member_archive")->move_to_master($discuz_uid);
	}
	$this->var["member"] = $user;
	$nickname = getuserprofile("nickname") ;
	$this->var["member"]["nickname"] = $nickname ;
} else {
	$user = array();
	$this->_init_guest();
}
