微擎和其他程序共用多个网页授权域名

思路所有登录授权走一个域名页面回调再分发

详细见代码

微擎framework\class目录下weixin.account.class.php目录下两个函数改为

如果我的版本老了根据参数改

	public function getOauthCodeUrl($callback, $state = '') {
            $baseUrl = "http://你的域名/getwxcode.html?appid={$this->account['key']}&redirect_uri={$callback}&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect";
        return $baseUrl;}
	
	public function getOauthUserInfoUrl($callback, $state = '') {
            $baseUrl = "http://你的域名/getwxcode.html?appid={$this->account['key']}&redirect_uri={$callback}&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect";
            return $baseUrl;
        }

getwxcode.html代码(转自他人处)
