java后台get和post请求访问接口

get访问其他项目接口

/**设备状态接口

Post访问代码

public void push(String space,String controll,String deviceNo,String status ,String version ,String url,String attach){
		String path="http://api.kdcm.net.cn/api/terminals/remote-control/data";
		HashMap paramMap = new HashMap();
		if(Integer.parseInt(controll)==3){ //获取磁盘空间
			paramMap.put("space", space);
		}else if (Integer.parseInt(controll)==6) {//软件版本
			paramMap.put("version", version);
		}else {
			paramMap.put("url", url); //屏幕截屏
			paramMap.put("attach", attach); //用户识别码
		}
		paramMap.put("type", controll);
		paramMap.put("deviceNo", deviceNo);
		paramMap.put("status", status);
		//传入要访问接口连接，和map数据
		NetTool.sendPost(path, paramMap);
