Spring :Inserting cookies in a REST call response
提问by user3242743
I am implementing REST API endpoints using spring mvc. I am trying to send back a HTTP response with a cookie value. This is the equivalent of what I need to do in ruby SINATRA :
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。这相当于我需要在 ruby SINATRA 中做的事情：
response.set_cookie('heroku-nav-data', :value => params['nav-data'], :path => '/')
This is what I have tried so far, but that didn't work :
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);
}
What should I do ? thanks.
我该怎么办 ？谢谢。

I finally found the solution :
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();

While it is possible to set a cookie using a raw Set-Cookieheader, it will be easier to use the Servlet API :
虽然可以使用原始Set-Cookie标头设置 cookie ，但使用 Servlet API 会更容易：
Add the HttpServletResponseparameter to your controller method, Spring will pass the relevant instance; then use the addCookiemethod :
将HttpServletResponse参数添加到您的控制器方法中，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);
}
You can also add more parameters to the cookie object if needed:
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);

You can use Spring API for Cookie: org.springframework.http.HttpCookie:
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);

Hey Here is the Example of how to add cookie to response object and reading the cookie from response object using @CookieParam
嘿，这是如何将 cookie 添加到响应对象并使用 @CookieParam 从响应对象读取 cookie 的示例
package com.ft.resources;
import javax.ws.rs.CookieParam;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.NewCookie;
import javax.ws.rs.core.Response;
@Path("/cookie")
public class CookieResource {
@GET
@Path("/write")
public Response write() {
//create cookie
NewCookie c1=new NewCookie("uname","gaurav");
NewCookie c2=new NewCookie("password","gaurav@123");
//adding cookie to response object
return Response.ok().cookie(c1,c2).build();
}
@GET
@Path("/read")
public Response read(@CookieParam("uname") String uname,@CookieParam("password")
String password) {
System.out.println(uname);
System.out.println(password);
String msg="Username:"+uname;
msg=msg.concat("</br>");
msg=msg.concat("Password:"+password);
return Response.ok(msg).build();
}
}
