Swagger 整合 Oauth2

一旦项目中加入了 Oauth2.0，那么每次请求接口都需要在 header 上带上 Authorization 参数才可以正常访问，如下所示：

项目用了 Swagger 在线接口文档组件，那么如何结合 Oauth2.0，让调用接口的时候自动带上认证参数呢？

关键代码

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    private static final String VERSION = "1.0.0";
    /**
     * 创建API
     */
    @Bean
    public Docket createRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //指定接口包所在路径
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                .paths(PathSelectors.any())
                .build()
                //整合oauth2
                .securitySchemes(Collections.singletonList(apiKey()))
                .securityContexts(Collections.singletonList(securityContext()));
    }

    /**
     * 添加摘要信息
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .contact(new Contact("JAVA日知录","http://javadaily.cn","jianzh5@163.com"))
                .title("account-server接口文档")
                .description("account-server接口文档")
                .termsOfServiceUrl("http://javadaily.cn")
                .version(VERSION)
                .build();
    }



    private ApiKey apiKey() {
        return new ApiKey("Bearer", "Authorization", "header");
    }


    /**
     * swagger2 认证的安全上下文
     */
    private SecurityContext securityContext() {
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .forPaths(PathSelectors.any())
                .build();
    }

    private List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope = new AuthorizationScope("web", "access_token");
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Collections.singletonList(new SecurityReference("Bearer",authorizationScopes));
    }
}
​

使用步骤

• 调用认证中心获取 access_token
  http://localhost:8090/auth-service/oauth/token

{
  "access_token": "36034ff7-7eea-4935-a3b7-5787d7a65827",
  "token_type": "bearer",
  "refresh_token": "4baea735-3c0d-4dfd-b826-91c6772a0962",
  "expires_in": 36931,
  "scope": "web"
}
​

• 访问 Swagger 接口页面，点击 Authorize 接口进行认证，在弹出框中输入 Bearer 36034ff7-7eea-4935-a3b7-5787d7a65827 并点击认证按钮。
  

• 在 Swagger 中正常请求接口
  

经过以上几步可以看到接口请求会默认带上认证参数，小伙伴们又可以愉快的玩耍了！
