本代码是为了防止伪造cookie。加一个秘钥来验证..
$s_uid = session("unionUid");<br>
$s_email = session("unionEmail");<br>
if (empty($s_uid) or empty($s_email)) { //若是session获取不到，则到cookie里面去取<br>
$c_uid = cookie("unionUid");<br>
$c_checkcode = cookie("unionCheckcode");//用来安全校验<br>
if (!empty($c_uid) && !empty($c_checkcode)) {<br>
if ($c_checkcode == getUnionLoginCheckcode($c_uid)) {<br>
$data = array(<br>
"userId" => $c_uid,<br>
);<br>
$userinfo = getCodeJson($data, 'getSiteUserInfo', '', '2');<br>
$s_email = $userinfo['userEmail'];<br>
session("unionUid", $c_uid);<br>
session("unionEmail", $s_email);<br>
} else {<br>
$c_uid = '';<br>
}<br>
}<br>
$s_uid = $c_uid;<br>
}秘钥获取方法：function getUnionLoginCheckcode($uid) {<br>
$privateKey = S("union_private_key");<br>
if (empty($privateKey)) {<br>
$data = array(<br>
"slug" => "userKey",<br>
);<br>
$rs = getCodeJson($data, 'getGlobalVarBySlug', '', 2);<br>
if ($rs) {<br>
$privateKey = $rs[0]['var']['value'];<br>
} else {<br>
$privateKey = "5edgka9gu724l7uslc";//若是通过接口获取不到秘钥。<br>
}<br>
S("union_private_key", $privateKey, 3600);<br>
}<br>
return md5($uid . $privateKey);<br>
