我按这里的开发文档进行“连接Wifi”

function Wechat_GotoRedirect(appId, extend, timestamp, sign, shopId, authUrl, mac, ssid, bssid){ 
	var url = "https://wifi.weixin.qq.com/operator/callWechatBrowser.xhtml?appId=" + appId + "&extend=" + extend + "×tamp=" + timestamp+ "&sign=" + sign; 
	if(authUrl && shopId){ 
		url = "https://wifi.weixin.qq.com/operator/callWechat.xhtml?appId=" + appId+ "&extend=" + extend + "×tamp=" + timestamp + "&sign=" + sign+ "&shopId=" + shopId+ "&authUrl=" + encodeURIComponent(authUrl)+ "&mac=" + mac+ "&ssid=" + ssid+ "&bssid=" + bssid; 
	}		   
	var script = document.createElement('script');  
	script.setAttribute('src', url);  
	document.getElementsByTagName('head')[0].appendChild(script);
}

我在页面调用。
方式一：
Wechat_GotoRedirect(appId, extend, timestamp, sign, shop_id, authUrl, mac, ssid, bssid );
正常调用，通过。
方式二：
Wechat_GotoRedirect(appId, extend, timestamp, sign );
调用失败， jsonpCallback({'success':false,'data':'AppId not registered'})
请问要怎么处理？
