Pha*_*s1c 22 java iframe spring-security cross-domain jsessionid
我正在尝试在不利用cookie的情况下管理Spring Security中的会话.原因是 - 我们的应用程序显示在另一个域的iframe中,我们需要在我们的应用程序中管理会话,并且Safari限制跨域cookie的创建.(上下文:domainA.com在iframe中显示domainB.com.domainB.com正在设置一个JSESSIONID cookie以在domainB.com上使用,但由于用户的浏览器显示domainA.com - Safari限制domainB.com创建cookie) .
我能想到的唯一方法(针对OWASP安全建议) - 将URL中的JSESSIONID作为GET参数包含在内.我不想这样做,但我想不出另一种选择.
所以这个问题都是关于:
回顾Spring的文档,使用enableSessionUrlRewriting应该允许这样做
所以我做到了这一点:
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.ALWAYS)
.enableSessionUrlRewriting(true)
这没有将JSESSIONID添加到URL,但现在应该允许它.然后我利用此问题中的一些代码将"跟踪模式"设置为URL
@SpringBootApplication
public class MyApplication extends SpringBootServletInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
super.onStartup(servletContext);
servletContext
.setSessionTrackingModes(
Collections.singleton(SessionTrackingMode.URL)
);
即使在此之后 - 应用程序仍然将JSESSIONID添加为cookie而不是URL.
有人可以帮助我指出正确的方向吗？
基于表单的登录主要是有状态会话。在您的场景中，使用无状态会话是最好的。
JWT为此提供了实现。它基本上是您需要在每个 HTTP 请求中作为标头传递的密钥。所以只要你有钥匙。API 可用。
我们可以将 JWT 与 Spring 集成。
基本上你需要编写这些逻辑。
我可以给你一个良好的开端
