Java 用suo.nz給長連結生成短連結

官方位址

private HashMap<String, Object> doSendSms(BusiTranInfo info, String mobilePhone)  {

    //要轉換的長的url連結
    String url ="https://xxx/";
        //key
    String shortConnectionTransitionKey = Global.getConfig(ApolloKey.SHORT_CONNECTION_TRANSITION_KEY);
        //shortConnectionTransitionUrl = http://suo.nz/api.php?format=json&url=
    String shortConnectionTransitionUrl = Global.getConfig(ApolloKey.SHORT_CONNECTION_TRANSITION_URL);

    HashMap<String,Object> map = Maps.newHashMap();

    try {
            // 擷取目前時間往後推遲7天
      Date now = new Date();
      Calendar calendar = new GregorianCalendar();
      calendar.setTime(now);
      calendar.add(Calendar.DATE, 7);
      Date time = calendar.getTime();
      SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
      String dateString = formatter.format(time);

      String data = url+"?orderId="+ info.getBusiId()+"&orderTypeCode=2" ;
      //對要轉換的長url編碼 import java.net.URLEncoder;
           data =  URLEncoder.encode(data) ;

        url=shortConnectionTransitionUrl+  //短連接配接的URLAPI
           data +"&key="+ shortConnectionTransitionKey +"&expireDate="+dateString;
      logger.info("面簽連結{}",url);

        // 調用人家的接口,轉成短連接配接
      String ret = HttpUtils.httpGet(url);
      JSONObject json = JSONObject.parseObject(ret);
      String suoUrl = json.getString("url");  // 這就是短連接配接位址了
      String err = json.getString("err");
         
    }
    } catch (Exception e) {
    }


    return map;
  }
