基于 Spring Security Token 的认证 [英] Spring Security Token based Authentication
问题描述
我有一个 rest api，我在其中使用 spring 安全基本授权进行身份验证，客户端为每个请求发送用户名和密码.现在，我想实现基于令牌的身份验证，当用户首先通过身份验证时，我将在响应标头中发送一个令牌.对于进一步的请求，客户端可以在标头中包含该令牌，该令牌将用于验证用户对资源的身份.我有两个身份验证提供程序 tokenAuthenticationProvider 和 daoAuthenticationProvider
I have a rest api where I am authenticating using spring security Basic Authorization where client sends username and password for each request. Now, I wanted to implement token based authentication where I will send a token in response header when user is authenticated at first. For further requests, client can include that token in the header which will be used to authenticate the user to the resources. I have two authentication providers tokenAuthenticationProvider and daoAuthenticationProvider
@Component
public class TokenAuthenticationProvider implements AuthenticationProvider {
@Autowired
private TokenAuthentcationService service;
@Override
public Authentication authenticate(final Authentication authentication) throws AuthenticationException {
final RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
final HttpServletRequest request = ((ServletRequestAttributes) requestAttributes).getRequest();
final String token = request.getHeader(Constants.AUTH_HEADER_NAME);
final Token tokenObj = this.service.getToken(token);
final AuthenticationToken authToken = new AuthenticationToken(tokenObj);
return authToken;
}
@Override
public boolean supports(final Class<?> authentication) {
return AuthenticationToken.class.isAssignableFrom(authentication);
}
}
在 daoAuthenticationProvider 中，我正在设置自定义 userDetailsService 并通过从数据库中获取用户登录详细信息进行身份验证(只要使用 Authorization:Basic bGllQXBpVXNlcjogN21wXidMQjRdTURtR04pag== 作为标头传递用户名和密码，它就可以正常工作)
And in daoAuthenticationProvider I am setting custom userDetailsService and authenticating against user login details by fetching it from the database (which is working fine as long as user name and password are passed using Authorization:Basic bGllQXBpVXNlcjogN21wXidMQjRdTURtR04pag== as header)
但是当我使用 X-AUTH-TOKEN(即 Constants.AUTH_HEADER_NAME)在标头中包含令牌时，不会调用 tokenAuthenticationProvider.我收到错误为
But when I include token in the header using X-AUTH-TOKEN (which is Constants.AUTH_HEADER_NAME), tokenAuthenticationProvider is not being called. I am getting error as
{"timestamp":1487626368308,"status":401,"error":"Unauthorized","message":"Full authentication is required to access this resource","path":"/find"}
这是我添加身份验证提供程序的方式.
And here is how I am adding authentication providers.
@Override
public void configure(final AuthenticationManagerBuilder auth) throws Exception {
final UsernamePasswordAuthenticationProvider daoProvider = new
UsernamePasswordAuthenticationProvider(this.service, this.passwordEncoder());
auth.authenticationProvider(this.tokenAuthenticationProvider);
auth.authenticationProvider(daoProvider);
}
请建议我如何在不损害 Spring Security 当前行为的情况下实现基于令牌的身份验证.
Please suggest how can I implement Token based authentication without hurting the current behavior of spring security.

这是我如何能够实现基于令牌的身份验证和基本身份验证
Here is how I was able to implement token based authentication and basic authentication
SpringSecurityConfig.java
SpringSecurityConfig.java
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter
{
@Override
public void configure(final AuthenticationManagerBuilder auth) throws Exception
{
auth.userDetailsService(this.participantService).passwordEncoder(this.passwordEncoder());
}
@Override
protected void configure(final HttpSecurity http) throws Exception
{
//Implementing Token based authentication in this filter
final TokenAuthenticationFilter tokenFilter = new TokenAuthenticationFilter();
http.addFilterBefore(tokenFilter, BasicAuthenticationFilter.class);
//Creating token when basic authentication is successful and the same token can be used to authenticate for further requests
final CustomBasicAuthenticationFilter customBasicAuthFilter = new CustomBasicAuthenticationFilter(this.authenticationManager() );
http.addFilter(customBasicAuthFilter);
}
}
TokenAuthenticationFilter.java
TokenAuthenticationFilter.java
public class TokenAuthenticationFilter extends GenericFilterBean
{
@Override
public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain)
throws IOException, ServletException
{
final HttpServletRequest httpRequest = (HttpServletRequest)request;
//extract token from header
final String accessToken = httpRequest.getHeader("header-name");
if (null != accessToken) {
//get and check whether token is valid ( from DB or file wherever you are storing the token)
//Populate SecurityContextHolder by fetching relevant information using token
final User user = new User(
"username",
"password",
true,
true,
true,
true,
authorities);
final UsernamePasswordAuthenticationToken authentication =
new UsernamePasswordAuthenticationToken(user, null, user.getAuthorities());
SecurityContextHolder.getContext().setAuthentication(authentication);
}
chain.doFilter(request, response);
}
}
CustomBasicAuthenticationFilter.java
CustomBasicAuthenticationFilter.java
@Component
public class CustomBasicAuthenticationFilter extends BasicAuthenticationFilter {
@Autowired
public CustomBasicAuthenticationFilter(final AuthenticationManager authenticationManager) {
super(authenticationManager);
}
@Override
protected void onSuccessfulAuthentication(final javax.servlet.http.HttpServletRequest request, final javax.servlet.http.HttpServletResponse response, final Authentication authResult) {
//Generate Token
//Save the token for the logged in user
//send token in the response
response.setHeader("header-name" , "token");
}
}
由于我们的 CustomBasicAuthenticationFilter 已配置并添加为 spring 安全性的过滤器，
As our CustomBasicAuthenticationFilter has been configured and added as a filter to the spring security,
每当基本身份验证成功时，请求将被重定向到 onSuccessfulAuthentication，我们在其中设置令牌并在响应中将其与一些标头header-name"一起发送.
Whenever basic authentication is successful the request will be redirected to onSuccessfulAuthentication where we set the token and send it in the response with some header "header-name".
如果为进一步请求发送header-name"，则该请求将在尝试尝试基本身份验证之前首先通过 TokenAuthenticationFilter.
If "header-name" is sent for further request, then the request will go through TokenAuthenticationFilter first before attempting to try Basic Authentication.
