RestTemplate

一、

@Component
public class HelpUtil {

   public static String getData(String url) throws ClientProtocolException,
         URISyntaxException, IOException {
      RestTemplate restTemplate = new RestTemplate();
      restTemplate.getMessageConverters().add(new StringHttpMessageConverter(Charset.forName("utf-8")));
      String rspMsg = restTemplate.getForObject(url,
            String.class);
      return rspMsg;
   }

   public static ResponseBean getByPostData(String url,Map<String,Object> params) throws ClientProtocolException,
         URISyntaxException, IOException {
      RestTemplate restTemplate = new RestTemplate();
        HttpHeaders headers = new HttpHeaders();
        headers.add("Content-Type", "application/x-www-form-urlencoded");
      MultiValueMap<String, Object> requestEntity = new LinkedMultiValueMap<>();
      for (String key:params.keySet()) {
         requestEntity.add(key,String.valueOf( params.get(key)));
      }
        HttpEntity<MultiValueMap<String, Object>> r = new HttpEntity<>(
                requestEntity, headers);
        ResponseBean rspMsg =  restTemplate.postForObject(url,r , ResponseBean.class);
      return rspMsg;

   }

   public static String getStrByPostData(String url,Map<String,Object> params) throws ClientProtocolException,
         URISyntaxException, IOException {
      RestTemplate restTemplate = new RestTemplate();
      HttpHeaders headers = new HttpHeaders();
      headers.add("Content-Type", "application/x-www-form-urlencoded");
      MultiValueMap<String, Object> requestEntity = new LinkedMultiValueMap<>();
      for (String key:params.keySet()) {
         requestEntity.add(key,String.valueOf( params.get(key)));
      }
      HttpEntity<MultiValueMap<String, Object>> r = new HttpEntity<>(
            requestEntity, headers);
      String rspMsg =  restTemplate.postForObject(url,r , String.class);
      return rspMsg;

   }

}

public String getToken(){
    try {
        String resultContent=  HelpUtil.getData(tokenUrl);
        Map<String, Object> resultMap = JSON.parseObject(resultContent,
                new TypeReference<Map<String, Object>>() {
                });
        Integer code = (Integer) resultMap.get("code");
        if(code==0){
            String dataJson = resultMap.get("data").toString();
            Map<String, Object> dataMap = (Map<String, Object>) resultMap.get("data");
            Integer expriesIn = (Integer) dataMap.get("expriesIn");
            String accessToken = (String) dataMap.get("accessToken");
           return  accessToken;
        }else{
            log.info("得到token报错->"+resultMap.toString());
        }
    }catch (Exception e){
        log.error("得到token报错->{}",e);
        return null;
    }
   return null;
}

public String getLastTime(String accessToken,String mobile){
    try {
        Map<String,Object> params=new HashMap<String,Object>();
        params.put("accessToken",accessToken);
        params.put("mobile",mobile);
        String resultContent=  HelpUtil.getStrByPostData(detail_url,params);
        Map<String, Object> resultMap = JSON.parseObject(resultContent,
                new TypeReference<Map<String, Object>>() {
                });
        Integer code = (Integer) resultMap.get("code");
        if(code==0 && null!=resultMap.get("data")){
            String dataJson = resultMap.get("data").toString();
            Map<String, Object> dataMap = (Map<String, Object>) resultMap.get("data");
            if(null!=dataMap.get("lastLoginTime")){
                String lastTime= dataMap.get("lastLoginTime").toString();
                SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                long lt = new Long(lastTime);
                Date date = new Date(lt);
                String dateFmt = simpleDateFormat.format(date);
                return dateFmt;
            }
        }else{
            log.info("得到lastTime报错->"+resultMap.toString());
        }
    }catch (Exception e){
        log.error("得到lastTime报错->{}",e);
        return null;
    }
    return null;
