java Spring Security 在休息服务中获取用户信息，用于经过身份验证和未经过身份验证的用户

Spring Security get user info in rest service, for authenticated and not authenticated users

提问by fyelci

I have a spring rest service, I want to use it for authenticated and not authenticated users. And I want to get user information from SecurityContextHolder.getContext().getAuthentication()if user is authenticated.

我有一个 spring 休息服务，我想将它用于经过身份验证和未经身份验证的用户。SecurityContextHolder.getContext().getAuthentication()如果用户通过身份验证，我想获取用户信息。

• If I use .antMatchers("/app/rest/question/useroperation/list/**").permitAll()in ouath2 configuration like below, then I can get user info for authenticated user, but 401 error for not authenticated users.
• If I .antMatchers("/app/rest/question/useroperation/list/**").permitAll()and ignore the url in WebSecurity by web.ignoring()..antMatchers("/app/rest/question/useroperation/list/**")in SecurityConfigurationlike below, then all users can call the service, but I cant get user information from SecurityContext.

• 如果我 .antMatchers("/app/rest/question/useroperation/list/**").permitAll()在下面的 ouath2 配置中使用，那么我可以获得经过身份验证的用户的用户信息，但对于未经过身份验证的用户会出现 401 错误。
• 如果我 .antMatchers("/app/rest/question/useroperation/list/**").permitAll()和忽略WebSecurity在URL中使用 web.ignoring()..antMatchers("/app/rest/question/useroperation/list/**")的SecurityConfiguration类似下面，那么所有用户都可以调用该服务，但我不能从SecurityContext中获取用户信息。

How can configure my spring security to call a url for authenticated and not authenticated users and get user info from SecurityContext if user logged in.

如果用户登录，如何配置我的 spring 安全来为经过身份验证和未经过身份验证的用户调用 url，并从 SecurityContext 获取用户信息。

permitAll()still requires Authenticationobject to present in SecurityContext.

permitAll()仍然需要Authentication对象出现在SecurityContext.

For not oauth users this can be achieved with anonymous access enabled:

对于非 oauth 用户，这可以通过启用匿名访问来实现：

@Override
public void configure(HttpSecurity http) throws Exception {
   http
//some configuration
     .and()
        .anonymous() //allow anonymous access
     .and()
        .authorizeRequests()
           .antMatchers("/views/**").permitAll()
//other security settings

Anonymous access will add additional filter: AnonymousAuthenticationFilterto the filter chain that populate AnonymousAuthenticationTokenas Authentication information in case no Authenticationobject in SecurityContext

匿名访问将添加额外的过滤器：AnonymousAuthenticationFilter到过滤器链，AnonymousAuthenticationToken在没有Authentication对象的情况下作为身份验证信息填充SecurityContext

I've this security config for check AuthUser by /public/auth:

我有这个安全配置来检查 AuthUser /public/auth：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.cors().and().authorizeRequests()
           .antMatchers("/api/skills/**", "/api/profile/**", "/api/info/**").authenticated()
           .antMatchers("/api/**").hasAuthority(Role.ROLE_ADMIN.getAuthority())
           .antMatchers("/public/auth").permitAll()
           .and().httpBasic()
           .and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
           .and().csrf().disable();
}

@GetMapping(value = "/public/auth")
private ResponseEntity<User> getAuthUser(@AuthenticationPrincipal AuthUser authUser) {
    return authUser == null ? 
               ResponseEntity.notFound().build() :
               ResponseEntity.ok(authUser.getUser());
}
