     * tw 新增函數， 小程序登錄
     * 過程： 小程序中運行 wx.login() 獲取 code, 然後調用 mp_auth_login
     * mp_auth_login 執行
     * 1. 從 code 解析出 openId, 根據 openId 檢查用戶，存在，則返回 token，登录成功
     * 2. 不存在該 openId, 則是新用戶，返回 失敗，需要小程序做 wx.getUserProfile 调用后，
     *      然后调用 mp_auth_login_with_userinfo 接口， 注册或刷新用户信息后，返回登录成功协议
     * 小程序調用成功，就登錄成功 (注意：此时有两个问题 1. 目前测试得不到 unionId; 
     *      2. 此时用户微信资料如果变动，不会刷新)
     * 小程序得到失败，就要求用户授权 wx.getUserProfile 获取微信资料，生成新的用户，返回 token， 相当与注册过程。
     * 
     * mp_auth_login 即使执行成功，过一段时间也要返回失败，使得小程序发起重新授权，刷新用户微信资料。
     * 
     * 返回字段：
     * 
     * 'token' => $token->token,
     * 'userInfo' => $userInfo,
     * 'expires_time' => strtotime($token->expires_time),
     * 'cache_key' => $cache_key
     * 以上兼容旧协议
     * 'status' => 0/1 0 表示正常登录成功， 1 表示需要进一步调用 wx.getUserProfile 进行授权
