我也看到了，回应中的饼干：

但是cookies不会保存在浏览器中。这是我在spring后端创建的第一方cookie。
在spring boot中，我创建了如下cookies：

import org.springframework.http.HttpCookie;
import org.springframework.http.ResponseCookie;

@Component
public class CookieUtil {

    public HttpCookie createAccessTokenCookie(String token, Long duration) {
        return ResponseCookie.from("accessToken", token).maxAge(duration).httpOnly(true).path("/").build();
    }

    public HttpCookie createRefreshTokenCookie(String token, Long duration) {
        return ResponseCookie.from("refreshToken", token).maxAge(duration).httpOnly(true).path("/").build();
    }
}
