原因，phpcms的bug，傳輸userid失敗導(dǎo)致的。

原來的代碼如下

/*

* 測試郵件配置

*/

public function send_newmail() {

$_username = param::get_cookie('_regusername');

$_userid = param::get_cookie('_reguserid');

$_ssouid = param::get_cookie('_reguseruid');

$newemail = $_GET['newemail'];

if($newemail==''){//郵箱為空，直接返回錯誤

return '2';

}

$this->_init_phpsso();

$status = $this->client->ps_checkemail($newemail);

if($status=='-5'){//郵箱被占用

exit('-1');

}

if ($status==-1) {

$status = $this->client->ps_get_member_info($newemail, 3);
if($status) {

$status = unserialize($status); //接口返回序列化，進(jìn)行判斷

if (!isset($status['uid']) || $status['uid'] != intval($_ssouid)) {

exit('-1');

}

} else {

exit('-1');

}

}

//驗證郵箱格式

pc_base::load_sys_func('mail');

$phpcms_auth_key = md5(pc_base::load_config('system', 'auth_key'));

$code = sys_auth($userid.'|'.SYS_TIME, 'ENCODE', $phpcms_auth_key);

$url = APP_PATH."index.php?m=member&c=index&a=register&code=$code&verify=1";

//讀取配置獲取驗證信息

$member_setting = getcache('member_setting');

$message = $member_setting['registerverifymessage'];

$message = str_replace(array('{click}','{url}','{username}','{email}','{password}'), array('<a href="'.$url.'">'.L('please_click').'</a>',$url,$_username,$newemail,$password), $message);

if(sendmail($newemail, L('reg_verify_email'), $message)){

//更新新的郵箱，用來驗證

$this->db->update(array('email'=>$newemail), array('userid'=>$_userid));

$this->client->ps_member_edit($_username, $newemail, '', '', $_ssouid);

$return = '1';

}else{

$return = '2';

}

echo $return;

}

修改后的如下：

/*

* 測試郵件配置

*/

public function send_newmail() {

$_username = param::get_cookie('_regusername');

$_userid = param::get_cookie('_reguserid');

$_ssouid = param::get_cookie('_reguseruid');

$newemail = $_GET['newemail'];

if($newemail==''){//郵箱為空，直接返回錯誤

return '2';

}

$this->_init_phpsso();

$status = $this->client->ps_checkemail($newemail);
if($status=='-5'){//郵箱被占用

exit('-1');

}

if ($status==-1) {

$status = $this->client->ps_get_member_info($newemail, 3);

if($status) {

$status = unserialize($status); //接口返回序列化，進(jìn)行判斷

if (!isset($status['uid']) || $status['uid'] != intval($_ssouid)) {

exit('-1');

}

} else {

exit('-1');

}

}

//驗證郵箱格式

pc_base::load_sys_func('mail');

$phpcms_auth_key = md5(pc_base::load_config('system', 'auth_key'));

$code = sys_auth($_userid.'|'.SYS_TIME, 'ENCODE', $phpcms_auth_key);

$url = APP_PATH."index.php?m=member&c=index&a=register&code=$code&verify=1";

//讀取配置獲取驗證信息

$member_setting = getcache('member_setting');

$message = $member_setting['registerverifymessage'];

$message = str_replace(array('{click}','{url}','{username}','{email}','{password}'), array('<a

href="'.$url.'">'.L('please_click').'</a>',$url,$_username,$newemail,$password), $message);

if(sendmail($newemail, L('reg_verify_email'), $message)){

//更新新的郵箱，用來驗證

$this->db->update(array('email'=>$newemail), array('userid'=>$_userid));

$this->client->ps_member_edit($_username, $newemail, '', '', $_ssouid);

$return = '1';

}else{

$return = '2';

}

echo $return;

}

ID傳輸失敗就自然不知道是認(rèn)證誰了，所以導(dǎo)致的老用戶傳輸ID失敗不能郵箱認(rèn)證。
