从cookies 获取token

从cookie中获取token，在根据token获取想要的数据

public String getToken2(HttpServletRequest request) throws Exception {
 try {
 Cookie[] cookies = request.getCookies();
 if (cookies != null && cookies.length > 0) {
 for (Cookie cookie : cookies) {
 if ("token".equals(cookie.getName())) {
 String token = cookie.getValue();
 HttpHeaders headers = new HttpHeaders();
 RestTemplate restTemplate = new RestTemplate();
 headers.put(HttpHeaders.COOKIE, Collections.singletonList("token=" + token));
 HttpEntity<String> requestEntity = new HttpEntity<>("", headers);
 ResponseEntity<String> responseEntity = restTemplate.exchange(accessTokenUrl, HttpMethod.GET, requestEntity, String.class);
 String body = responseEntity.getBody();
 JSONObject bodyObj = JSON.parseObject(body);
 Integer code = bodyObj.getInteger("code");
 if (code == 200 ) {
 JSONObject object = bodyObj.getJSONObject("member");
 String uid = object.getString("uid");
 return uid;
 }
 break;
 }
 }
 }
 } catch (Exception e) {
 e.printStackTrace();
 }
 return null;
}
