java微信公众号模板消息发送接口问题

Question

java代码如下

 /**
     * 发送注册成功模板消息
     * @return
     */
    public static String toSendModelMessage(String openId,String phone,String id,String dayStr){
        String accessToken=getAccessToken();
        if(accessToken.length()<=0){
            return "";
        }
        System.out.println("accessToken==="+accessToken);
        String urlStr="https://api.weixin.qq.com/cgi-bin/message/template/send?access_token="+accessToken;
        try {
            URL url = new URL(urlStr);
            HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection();
            urlConnection.setDoOutput(true);
            urlConnection.setDoInput(true);
            urlConnection.setRequestMethod("POST");
            urlConnection.setUseCaches(false); 
            urlConnection.setInstanceFollowRedirects(true);
            urlConnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
            urlConnection.setRequestProperty("Charset", "UTF-8"); 
            urlConnection.connect();
            DataOutputStream out = new DataOutputStream(urlConnection.getOutputStream());
            String params="{"+

                                "\"remark\":{"+
                                "\"value\":\"点击跳转\","+

                             "}"+
                            "}";        
            System.out.println(params);
            out.writeBytes(params);
            out.flush();
            out.close(); 
            BufferedReader reader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(),"UTF-8"));
            String line;
            String responseStr="";
            while ((line = reader.readLine()) != null){
                responseStr+=line;
            }
            System.out.println(responseStr);
            reader.close();
            urlConnection.disconnect();

        }catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ProtocolException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return "";
    }

返回的结果如下

 {"errcode":47001,"errmsg":"data format error hint: [IGparA0715ge14]"}

以下是我打印出来的请求json

    "touser":"on3mAwuljdY12JuRbua28EUCgW9o",
    "template_id":"ZvG8sGRKqo2Hk-OFRkHVLbvaeZTX7DDJFyS3G-0mb4A",

        },
        "keyword1":{
            "value":"18520040243",
            "color":"#173177"

        },
        "remark":{
            "value":"点击跳转",
            "color":"#173177"
        }
    }
}

很想知道我错在哪！求有经验的同学指点下
