将 Swagger Basic AUTH 添加到 Spring Boot 应用程序

Question

Requirements:

• Spring Boot application with Springfox
• Add BASIC authentication to Swagger
• Pass on all other requests

Code: implemented

@EnableWebSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
                .antMatchers("/swagger-resources/*", "*.html", "/api/v1/swagger.json")
                .hasAuthority("SWAGGER")
                .anyRequest().permitAll()
            .and()
                .httpBasic()
            .and()
                .csrf().disable();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().withUser("admin").password("admin").authorities("SWAGGER");
    }
}

This code however does not work - you can freely browse /swagger-ui.html#/ without any authentcation.

Question is - why BASIC auth and user do not apply to swagger ui endpoint?

Answer 1

You should use the .authenticated() instead of .permitAll() :

.authorizeRequests()
    .antMatchers("/swagger-resources/*", "*.html", "/api/v1/swagger.json")
        .hasRole("SWAGGER")
    .anyRequest()
        .authenticated()

This will:

• Restrict access to all resources matching /swagger-resources/* , *.html and /api/v1/swagger.json

• Allow unauthenticated access to all other resources

For clarification on why your configuration doesn't work, it's because you're not reading spring-security like you should be reading it.

Your old configuration reads like this:

.authorizeRequests() // allow requests
    .antMatchers(...) // that matches this
        .hasAuthority("SWAGGER") // with SWAGGER authority
    .anyRequest() // All requests above
        .permitAll() // grant full access 

In other words, you're granting full access to users with the SWAGGER authority, but what you've neglected is that by default, they already have access to it. To be more precise, everybody has access to it unless you specify otherwise .

By using .authenticated() . you're telling Spring that you want all requests matched to be restricted to people with the proper role or authority .

New configuration:

.authorizeRequests() // allow requests
    .antMatchers(...) // that matches this
        .hasRole("SWAGGER") // with role SWAGGER
    .anyRequest() // all requests above
        .authenticated() // needs authentication

Update

Regarding your issue with /swagger-resources , /swagger-resources/configuration/security and swagger-resources/configuration/ui returning 401:

You should replace /swagger-resources/* for /swagger-resources/** .

Update 2

Add the following at the end of your configuration to permit all non-matched requests:

.authorizeRequests()
    .anyRequest()
        .permitAll();

Answer 2

You could do something like below

Swagger

The code for swagger is like below.

    private List<SecurityScheme> basicScheme() {
        List<SecurityScheme> schemeList = new ArrayList<>();
        schemeList.add(new BasicAuth("basicAuth"));
        return schemeList;
    }

    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
            .
            .
            .
            .securitySchemes(basicScheme());
    }

Security Config

For the security config

    public void configureGlobal(final AuthenticationManagerBuilder auth)
        throws Exception {
        auth.inMemoryAuthentication()
                .withUser("USER")
                .password("PASSWORD")
                .roles("ADMIN");
    }
    .
    .
    .
    @Override
    protected void configure(final HttpSecurity httpSecurity) throws Exception {
        httpSecurity.csrf().disable().authorizeRequests()
    .anyRequest().authenticated().and().sessionManagement()
            .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and().httpBasic();
    }
    .
    .
    .
    @Override
    public void configure(final WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/v2/api-docs",
            "/configuration/ui",
            "/swagger-resources/**",
            "/webjars/**",
            "/configuration/security",
            "/swagger-ui.html");
    }

Controllers

Below passes the authorization to the methods using swagger.

   @PutMapping("/registration/{id}")
    @ApiOperation(value = "Update registration detail",
                  authorizations = { @Authorization(value="basicAuth") })
    public ResponseEntity<RegistrationModel> updateRegistration(

POM

and in your pom.xml, you will be needing:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

That's basically it.

Answer 3

Your configuration is strange. You can try something like that:

public static void configure(HttpSecurity http) throws Exception {
    http.csrf().disable()
    .antMatcher("/swagger-ui.html")
    .authorizeRequests()
        .anyRequest().hasAnyRole("SWAGGER")
        .and()
    .httpBasic();
}

This ensures authorization to swagger-ui.html path (with SWAGGER role).
