map拼接URL参数

请求参数不确定时,可以使用map传入,拼接后发起请求,提高代码的复用性

private static String paramsConvertUrl(Map<String, Object> params) {
        StringBuilder urlParams = new StringBuilder("?");
        Set<<String, Object>> entries = ();
        for (<String, Object> entry : ()) {
            (()).append("=").append(()).append("&");
        }
        String urlParamsStr = ();
        return (0, ()-1);
    }
