Spring:在REST调用响应中插入cookie

Question

我正在使用spring mvc实现REST API端点.我试图发回一个带有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 => '/')

这是我到目前为止所尝试的,但是没有用:

@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.

Answer 1

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

将HttpServletResponse参数添加到控制器方法中,Spring将传递相关实例; 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);

我终于找到了解决方案:

HttpHeaders headers = new HttpHeaders();
headers.add("Set-Cookie","key="+"value");
ResponseEntity.status(HttpStatus.OK).headers(headers).build();

您可以将Spring API用于Cookie：org.springframework.http.HttpCookie：

HttpCookie cookie = ResponseCookie.from("heroku-nav-data", nav_data)
        .path("/")
        .build();
return ResponseEntity.ok()
        .header(HttpHeaders.SET_COOKIE, cookie.toString())
        .body(id);
