quick-cocos2d-x解析json

先声明下我采用的是http服务器，客户端用的curl。

下面是我服务器端代码，我用的是jetty，其他服务器的都类似：

[java] public class JsonServlet extends HttpServlet {

    private static final long serialVersionUID = 1L;

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        resp.setContentType("application/json");
        resp.setCharacterEncoding("UTF-8");
        Map map = new HashMap();
        map.put( "name", "json" );
        map.put( "bool", Boolean.TRUE );
        map.put( "int", new Integer(1) );
        map.put( "arr", new String[]{"a","b"} );
        String jsonStr=JSONArray.fromObject(map).toString();
        resp.getWriter().println(jsonStr);
        resp.flushBuffer();
        System.out.println(jsonStr);
    }

}

public class JsonServlet extends HttpServlet {

private static final long serialVersionUID = 1L;

@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
   throws ServletException, IOException {
  resp.setContentType("application/json");
  resp.setCharacterEncoding("UTF-8");
  Map map = new HashMap();
        map.put( "name", "json" );
        map.put( "bool", Boolean.TRUE );
        map.put( "int", new Integer(1) );
        map.put( "arr", new String[]{"a","b"} );
        String jsonStr=JSONArray.fromObject(map).toString();
        resp.getWriter().println(jsonStr);
        resp.flushBuffer();
        System.out.println(jsonStr);
}

}熟悉json的同学可以看懂我返回的json的数据。

下面是客户端lua代码：

[html] local function callback(event)
    local ok = (event.name == "completed")
    local request = event.request
    local response = request:getResponseString()
     print(response)
    local json=require("framework.shared.json")
    local t=json.decode(response)
    print(t)
end

local request = network.createHTTPRequest(callback, "http://localhost:8080/json", "POST")
request:start()

local function callback(event)
local ok = (event.name == "completed")
local request = event.request
local response = request:getResponseString()
print(response)
local json=require("framework.shared.json")
local t=json.decode(response)
print(t)
end

local request = network.createHTTPRequest(callback, "http://localhost:8080/json", "POST")
request:start()
其中http://........./json是上面servlet的响应url。

json.decode()函数会返回一个已经解析好的table也就是上面的变量t。

然后就可以通过t来访问获取到的数据了。
