$s_uid = session("unionUid");
$s_email = session("unionEmail");
if (empty($s_uid) or empty($s_email)) { //若是session获取不到，则到cookie里面去取
$c_uid = cookie("unionUid");
$c_checkcode = cookie("unionCheckcode");//用来安全校验
if (!empty($c_uid) && !empty($c_checkcode)) {
if ($c_checkcode == getUnionLoginCheckcode($c_uid)) {
$data = array(

session("unionUid", $c_uid);

} else {
$c_uid = '';
}
}
$s_uid = $c_uid;
}秘钥获取方法：function getUnionLoginCheckcode($uid) {
$privateKey = S("union_private_key");
if (empty($privateKey)) {
$data = array(
"slug" => "userKey",
);
$rs = getCodeJson($data, 'getGlobalVarBySlug', '', 2);
if ($rs) {
$privateKey = $rs[0]['var']['value'];
} else {
$privateKey = "5edgka9gu724l7uslc";//若是通过接口获取不到秘钥。
}
S("union_private_key", $privateKey, 3600);
}
return md5($uid . $privateKey);
