java - Spring :Inserting cookies in a REST call response

Question

我正在使用 spring mvc 实现 REST API 端点。我正在尝试发回带有 cookie 值的 HTTP 响应。这相当于我在 ruby​​ SINATRA 中需要做的事情:

  response.set_cookie('heroku-nav-data', :value => params['nav-data'], :path => '/')

这是我迄今为止尝试过的，但没有奏效:

@RequestMapping(value = "/login", method = RequestMethod.POST)
    public ResponseEntity<String> single_sign_on(@RequestBody String body_sso) {

        String[] tokens = body_sso.split("&");
        String nav_data=tokens[3].substring(9);
        String id = tokens[2].substring(3);
        String time_param = tokens[0].substring(10);
        long timestamp= Long.valueOf(time_param).longValue(); 

        String pre_token = id+':'+HEROKU_SSO_SALT+':'+time_param;
        String token = DigestUtils.shaHex(pre_token);
         long lDateTime = new Date().getTime()/1000;
        if (!((token.equals(tokens[4].substring(6))) && ((lDateTime-timestamp)<300)))
        {   
            return new ResponseEntity<String>(HttpStatus.FORBIDDEN);
        }

        HttpHeaders headers = new HttpHeaders();
        headers.add("heroku-nav-data",nav_data);// this didn't work
        return new ResponseEntity<String>(id,headers,HttpStatus.OK);    

}

我该怎么办？谢谢。

虽然可以使用原始 Set-Cookie header 设置 cookie，但使用 Servlet API 会更容易:

在你的 Controller 方法中添加HttpServletResponse参数，Spring会传递相关实例；然后使用 addCookie 方法:

@RequestMapping(value = "/login", method = RequestMethod.POST)
public ResponseEntity<String> singleSignOn(@RequestBody String bodySso, HttpServletResponse response) {

    response.addCookie(new Cookie("heroku-nav-data", navData));
    return new ResponseEntity<String>(id,headers,HttpStatus.OK);    

}

如果需要，您还可以向 cookie 对象添加更多参数:

final Cookie cookie = new Cookie(this.cookieName, principal.getSignedJWT());
cookie.setDomain(this.cookieDomain);
cookie.setSecure(this.sendSecureCookie);
cookie.setHttpOnly(true);
cookie.setMaxAge(maxAge);
response.addCookie(cookie);
