[onethink ucenter] 跨域名单点登录关键点

1、uc_client/data/cache/apps.php

<?php
$_CACHE['apps'] = array (
  1 => 
  array (
    'appid' => '1',
    'type' => 'OTHER',
    'name' => 'myapp',
    'url' => 'http://myapp.com',
    'ip' => '',
    'viewprourl' => '',
    'apifilename' => 'uc.php',
    'charset' => '',
    'synlogin' => '1',
    'extra' => 
    array (
      'apppath' => '',
    ),
    'recvnote' => '1',
  ),
  2 => 
  array (
    'appid' => '2',
    'type' => 'OTHER',
    'name' => 'yourapp',
    'url' => 'http://yourapp.com',
    'ip' => '',
    'viewprourl' => '',
    'apifilename' => 'uc.php',
    'charset' => '',
    'synlogin' => '1',
    'extra' => 
    array (
      'apppath' => '',
    ),
    'recvnote' => '1',
  ),
  'UC_API' => 'http://uc_server.com',
);

　超过2个应用(app)才执行同步登陆的

#file: uc_client/client.php
#function: uc_user_synlogin
if(count($_CACHE['apps']) > 1) { // 大于2才同步登陆
	$return = uc_api_post('user', 'synlogin', array('uid'=>$uid));
} else {
	$return = '';
}

2 config.inc.php

$cookiedomain = '';
