GlobalVars.serviceUrl = http://192.168.0.106:8080/text/login.jsp

1 获取 HttpURLConnection 返回的 cookie 和内部的 sessionId

sessionId格式如 JSESSIONID=XXXXXXXXXXXX.tomcat1 不同的服务器SESSION名字是不一样的，

这里我们暂时认为都含有SESSIONID

responseCode = conn.getResponseCode();if (responseCode == HttpURLConnection.HTTP_OK) {	InputStream response_in = conn.getInputStream(); 	GlobalVars.HttpSetCookies = conn.getHeaderFields().get("Set-Cookie");	if(GlobalVars.HttpSessionid==null){		for(String value:GlobalVars.HttpSetCookies){			//默认情况下 SESSION_ID_NAME 必定含有 SESSIONID			if(value.toUpperCase().indexOf("SESSIONID")>0){				GlobalVars.HttpSessionid = value;			}		}			}}

2 HttpURLConnection提交时加入 sessionId

url = new URL(str_remotecallservlerurl);conn = (HttpURLConnection)url.openConnection();if(GlobalVars.HttpSessionid !=null ){	conn.setRequestProperty("Cookie",GlobalVars.HttpSessionid);}

3 webview 初始化前 将cookie写入activity的本地即可

	CookieSyncManager.createInstance(this);  	CookieManager cookieManager = CookieManager.getInstance();  	cookieManager.setCookie(GlobalVars.serviceUrl, GlobalVars.HttpSetCookies.toString()); 	    			CookieSyncManager.getInstance().sync(); 

HttpURLConnection webview sessionId 连贯性
