Linux环境下Swagger的认证与授权如何实现 - 问答

在Linux环境下，Swagger的认证与授权可以通过多种方式实现，以下是一些常见的方法：

1. 基本认证（Basic Authentication）

基本认证是最简单的认证方式，客户端需要提供用户名和密码。

实现步骤：

添加依赖：在pom.xml中添加Spring Security依赖。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

配置Spring Security：创建一个配置类来设置基本认证。

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/swagger-ui/**").authenticated()
            .and()
            .httpBasic();
    }

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

配置Swagger：确保Swagger配置允许基本认证。

import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.example.demo"))
            .paths(PathSelectors.any())
            .build();
    }
}

2. OAuth2认证

OAuth2是一种更复杂的认证方式，支持多种授权模式。

实现步骤：

添加依赖：在pom.xml中添加Spring Security和OAuth2依赖。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.security.oauth.boot</groupId>
    <artifactId>spring-security-oauth2-autoconfigure</artifactId>
    <version>2.5.2</version>
</dependency>

配置Spring Security：创建一个配置类来设置OAuth2认证。

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.JwtTokenStore;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/swagger-ui/**").authenticated()
            .and()
            .oauth2ResourceServer()
            .jwt();
    }
}

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/swagger-ui/**").authenticated();
    }

    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(accessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setSigningKey("123"); // 设置签名密钥
        return converter;
    }
}

配置Swagger：确保Swagger配置允许OAuth2认证。

import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.example.demo"))
            .paths(PathSelectors.any())
            .build()
            .securitySchemes(Arrays.asList(securityScheme()))
            .securityContexts(Arrays.asList(securityContext()));
    }

    private SecurityScheme securityScheme() {
        return new OAuthBuilder()
            .name("oauth2")
            .grantTypes(Arrays.asList(new ResourceOwnerPasswordCredentialsGrant("http://localhost:8080/oauth/token")))
            .scopes(Arrays.asList(new Scope("read", "read access"), new Scope("write", "write access")))
            .build();
    }

    private SecurityContext securityContext() {
        return SecurityContext.builder()
            .securityReferences(defaultAuth())
            .forPaths(PathSelectors.regex("/swagger-ui/.*"))
            .build();
    }

    List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope = new AuthorizationScope("read", "read access");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Arrays.asList(new SecurityReference("oauth2", authorizationScopes));
    }
}

3. API密钥认证

API密钥认证是一种简单的认证方式，客户端需要在请求头中提供API密钥。

实现步骤：

添加依赖：在pom.xml中添加Spring Security依赖。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-security</artifactId>
</dependency>

配置Spring Security：创建一个配置类来设置API密钥认证。

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter;

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers("/swagger-ui/**").authenticated()
            .and()
            .addFilterBefore(apiKeyFilter(), UsernamePasswordAuthenticationFilter.class);
    }

    @Bean
    public ApiKeyFilter apiKeyFilter() {
        return new ApiKeyFilter();
    }
}

import org.springframework.web.filter.OncePerRequestFilter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class ApiKeyFilter extends OncePerRequestFilter {

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws ServletException, IOException {
        String apiKey = request.getHeader("X-API-KEY");
        if (apiKey != null && apiKey.equals("your-api-key")) {
            // 认证成功
            chain.doFilter(request, response);
        } else {
            // 认证失败
            response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        }
    }
}

配置Swagger：确保Swagger配置允许API密钥认证。

import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.example.demo"))
            .paths(PathSelectors.any())
            .build()
            .securitySchemes(Arrays.asList(apiKey()))
            .securityContexts(Arrays.asList(securityContext()));
    }

    private ApiKey apiKey() {
        return new ApiKey("X-API-KEY", "X-API-KEY", "header");
    }

    private SecurityContext securityContext() {
        return SecurityContext.builder()
            .securityReferences(defaultAuth())
            .forPaths(PathSelectors.regex("/swagger-ui/.*"))
            .build();
    }

    List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope = new AuthorizationScope("read", "read access");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Arrays.asList(new SecurityReference("X-API-KEY", authorizationScopes));
    }
}

以上是几种常见的Swagger认证与授权实现方式，可以根据具体需求选择合适的方法。
