HttpURLConnection webview sessionId 连贯性

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();
