上面是json的请求方式，参数只需要传一个对应的服务器地址就行，下面是解析格式
String json = HttpUtils.getHttpText(
Configs.getServerAddress(context)
+ "/api.php/Message/getMessage"
+ Configs.getRoomInfo(context));
if (json == null || json.equals(""))
continue;
try {
JSONObject root = new JSONObject(json);
if (root.getInt("status") != 0)
return;
boolean gotMessage = false;
JSONArray ja = root.getJSONArray("messageList");
int len = ja.length();
long now = System.currentTimeMillis();
for (int i = 0; i < len; i++) {
JSONObject jo = ja.getJSONObject(i);
long deadline = jo.getLong("finish_time") * 1000;
if (deadline <= now) continue;
MarqueeContent content = new MarqueeContent();
content.id = mMarqueeId++;
content.deadline = deadline;
content.text = jo.getString("content");
mMarqueeList.add(content);
gotMessage = true;
}
if (gotMessage) {
context.sendBroadcast(new Intent(MarqueeView.GOT_MARQUEE_ACTION));
}
return;
} catch (JSONException e) {
e.printStackTrace();
}
