Question

我是Spring Boot的新手，所以请帮助我。我已经使其工作到可以通过未经身份验证的请求生成Bearer Token的地步。接下来，我想将此令牌与端点一起使用，以便对我的请求进行身份验证-这就是麻烦所在。我总是收到401，看起来我的配置有问题。这是我的代码

public class ApplicationUser {

private String username;
private String password;
private String role;

public ApplicationUser(String username, String password, String role) {
    this.username = username;
    this.password = password;
    this.role = role;
}

public String getUsername() {
    return username;
}

public String getPassword() {
    return password;
}

public String getRole() {
    return role;
    }
}

JwtConfig类：

@Component("jwtConfig")
public class JwtConfig {
@Value("${security.jwt.uri:/auth/**}")
private String Uri;

@Value("${security.jwt.header:Authorization}")
private String header;

@Value("${security.jwt.prefix:Bearer }")
private String prefix;

@Value("${security.jwt.expiration:#{24*60*60}}")
private int expiration;

@Value("${security.jwt.secret:JwtSecretKey}")
private String secret;

public String getUri() {
    return Uri;
}

public String getHeader() {
    return header;
}

public String getPrefix() {
    return prefix;
}

public int getExpiration() {
    return expiration;
}

public String getSecret() {
    return secret;
}
}

JwtTokenAuthenticationFilter

public class JwtTokenAuthenticationFilter extends  OncePerRequestFilter {

private final JwtConfig jwtConfig;

public JwtTokenAuthenticationFilter(JwtConfig jwtConfig) {
    this.jwtConfig = jwtConfig;
}

@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain)
        throws ServletException, IOException {

    // 1. get the authentication header. Tokens are supposed to be passed in the authentication header
    String header = request.getHeader(jwtConfig.getHeader());

    // 2. validate the header and check the prefix
    if(header == null || !header.startsWith(jwtConfig.getPrefix())) {
        chain.doFilter(request, response);          // If not valid, go to the next filter.
        return;
    }

    // If there is no token provided and hence the user won't be authenticated.
    // It's Ok. Maybe the user accessing a public path or asking for a token.

    // All secured paths that needs a token are already defined and secured in config class.
    // And If user tried to access without access token, then he won't be authenticated and an exception will be thrown.

    // 3. Get the token
    String token = header.replace(jwtConfig.getPrefix(), "");

    try {   // exceptions might be thrown in creating the claims if for example the token is expired

        // 4. Validate the token
        Claims claims = Jwts.parser()
                .setSigningKey(jwtConfig.getSecret().getBytes())
                .parseClaimsJws(token)
                .getBody();

        String username = claims.getSubject();
        if(username != null) {
            @SuppressWarnings("unchecked")
            List<String> authorities = (List<String>) claims.get("authorities");

            // 5. Create auth object
            // UsernamePasswordAuthenticationToken: A built-in object, used by spring to represent the current authenticated / being authenticated user.
            // It needs a list of authorities, which has type of GrantedAuthority interface, where SimpleGrantedAuthority is an implementation of that interface
            UsernamePasswordAuthenticationToken auth = new UsernamePasswordAuthenticationToken(
                    username, null, authorities.stream().map(SimpleGrantedAuthority::new).collect(Collectors.toList()));

            // 6. Authenticate the user
            // Now, user is authenticated
            SecurityContextHolder.getContext().setAuthentication(auth);
        }

    } catch (Exception e) {
        // In case of failure. Make sure it's clear; so guarantee user won't be authenticated
        SecurityContextHolder.clearContext();
    }

    // go to the next filter in the filter chain
    chain.doFilter(request, response);
}

JwtUsernameAndPasswordAuthenticationFilter

    // By default, UsernamePasswordAuthenticationFilter listens to "/login" path.
    // In our case, we use "/auth". So, we need to override the defaults.
    this.setRequiresAuthenticationRequestMatcher(new AntPathRequestMatcher(jwtConfig.getUri(), "POST"));
}

@Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
        throws AuthenticationException {

    try {

        // 1. Get credentials from request

        // 2. Create auth object (contains credentials) which will be used by auth manager
        UsernamePasswordAuthenticationToken authToken = new UsernamePasswordAuthenticationToken(
                creds.getUsername(), creds.getPassword(), Collections.emptyList());

        // 3. Authentication manager authenticate the user, and use UserDetialsServiceImpl::loadUserByUsername() method to load the user.
        return authManager.authenticate(authToken);

    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}

// Upon successful authentication, generate a token.
// The 'auth' passed to successfulAuthentication() is the current authenticated user.
@Override

    Long now = System.currentTimeMillis();
    String token = Jwts.builder()
            .setSubject(auth.getName())
            // Convert to list of strings.
            // This is important because it affects the way we get them back in the Gateway.
            .claim("authorities", auth.getAuthorities().stream()

对v1/cooks的调用始终返回401。我缺少配置的哪一部分？我遵循了https://medium.com/omarelgabrys-blog/microservices-with-spring-boot-authentication-with-jwt-part-3-fafc9d7187e8

上的文档

但是我现在完全迷路了。请求网址为GET http://localhost:9100/v1/cooks

响应为

编辑：从pom添加了application.properties和依赖项

Answer 1

根据您的需求，在对多个路径使用多种身份验证之前，您实际上不需要多个http安全配置（例如对于您想要拥有JWT的某些路径以及对于某些您想要具有基本auth或auth2的路径））。

因此，删除SecurityCredentialsConfig并将WebSecurity更新到下面，您会很好。

@Configuration
@EnableWebSecurity(debug = true)    // Enable security config. This annotation denotes config for spring security.
public class WebSecurity extends WebSecurityConfigurerAdapter {
    @Autowired
    private JwtConfig jwtConfig;

    @Autowired
    private UserDetailsServiceImpl userDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .csrf().disable()
                // make sure we use stateless session; session won't be used to store user's state.
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                // authorization requests config
                .authorizeRequests()
                // allow all who are accessing "auth" service
                .antMatchers(HttpMethod.POST, jwtConfig.getUri()).permitAll()
                // must be an admin if trying to access admin area (authentication is also required here)
                .antMatchers("/v1/cooks/**").hasAuthority("ADMIN")
                //for other uris
                //   .antMatchers(HttpMethod.GET, "/v1/**").hasRole("USER")
                // Any other request must be authenticated
                .anyRequest().authenticated()
                .and()
                // handle an authorized attempts
                .exceptionHandling().authenticationEntryPoint((req, rsp, e) -> rsp.sendError(HttpServletResponse.SC_UNAUTHORIZED))
                .and()
                // Add a filter to validate the tokens with every request
                .addFilterAfter(new JwtTokenAuthenticationFilter(jwtConfig), UsernamePasswordAuthenticationFilter.class)
                .addFilter(new JwtUsernameAndPasswordAuthenticationFilter(authenticationManager(), jwtConfig));
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
    }

    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

Answer 2

尝试添加此

/ **

WebSecurity类中的在线

.antMatchers("/v1/cooks/**" ).access("hasRole('ADMIN')")

请提供关于春季启动和安全性相关性的日志和版本，这对我们有很大帮助。

Answer 3

@ KK1957

尝试从cookAPI删除spring-boot-starter-security依赖性。
我已经看到，在zuul-server application.properties中仅添加了auth-service。在cookAPI属性文件中为cookAPI提供一个端口和应用程序名称。将其添加到zuul属性文件中。 zuul property file 我遵循了您提到的同一教程。
