Post请求案例
实例一：接口入参为对象

public ManagementBagRsult ManagementDetainedBags(DetentionBagParam param) {       
        Gson os=new Gson();
        String paramStr=os.toJson(param);
        try {
            String result = HttpUtils.httpPost(WebApiUrl.ManagementDetainedBags_Url,paramStr);
            ManagementBagRsult info = os.fromJson(result, ManagementBagRsult.class);
            return info;
        } catch (Exception ex) {
            Log.i("TAG", String.format("ScanBagInfoContractImpl/ManagementDetainedBags:{0}", ex.toString()));
            return null;
        }
    }

实例二：接口入参为String单个属性

public class LoginContractImpl implements ILoginContract {
    private static final Logger logger = LoggerFactory.getLogger();
    @Override
    public ApLoginResult  doLogin(DetentionBagParam param) {
        try {
            //传入参数,获得结果集
            String result = HttpUtils.httpPost(WebApiUrl.Login_Url+"?OrganizationCode="+param.OrganizationCode+"&UserWorkNumber="+param.UserWorkNumber+"&UserPassWord="+param.UserPassWord, "");
            //序列化一个泛型对象
            Gson gs = new Gson();
            ApLoginResult info = gs.fromJson(result, ApLoginResult.class);
            return info;
        } catch (Exception ex) {
            logger.info(String.format("LoginContractCompl发生异常:{0}", ex.toString()));
            return null;
        }
    }
}

实例三：GET请求

public Boolean SetLocactionIsFull(String locaton_code) {
        String params="location_code="+locaton_code;
        try {
            String result=HttpUtils.httpGet(WebApiUrl.SetLocactionIsFull_Url, params);
            //获取对应的值
            if (result == null) return false;
            //反序列化一个泛型对象
            Gson gs = new Gson();
            Type jsonType = new TypeToken<RequestModel.Request<Boolean>>() {}.getType();
            RequestModel.Request<Boolean> res= gs.fromJson(result, jsonType);
            if(res!=null && res.ResultCode.equals("0000") && res.ResultDesc.equals("接口调用成功")){
                return res.Item;
            }
        } catch (Exception ex) {
            logger.info(String.format("{0}/{1}发生异常:{2}", "QuickShelfContractImpl", "InStoresOperating", ex.toString()));
        }
        return false;
}
