请求参数：

{
"jsonStr":{
		  "clientFlag": "84:21:F1:96:A5:00",
		  "command": "indexQuery",
		  "params": {
		    "itemList": [
		      {
		        "class": "mpeg",
		        "col": "tsBitrate"
		      },
		      {
		        "class": "mpeg",
		        "col": "tsMlr"
		      },
		      {
		        "class": "has",
		        "col": "downRate"
		      }
		    ]
		  }
		}
}

未获取到jsonStr值：

public Object userInfo(@Param("..") SouthInputParam parm) throws Exception {
		String paramsAsJson=parm.getJsonStr();
		Map<String, Object> params = new HashMap<>();
		params.put("iptvNo", "itv047180010923");
		if(parm.getAreaCode()==null)
			throw new Exception("param is null");
		String url =Webs.Config.get("node-stb-probe");
		Map<String, String> headers=new HashMap<>();
		headers.put("Content-Type", "application/json");
		Header header=Header.create(headers);
		Request request=Request.create(url,METHOD.POST, paramsAsJson, header);
		String rcontent = Sender.create(request)
								.send()
								.getContent();
		
		System.out.println(rcontent);
		return parm;
	}
