标签： java spring-boot swagger swagger-ui springfox

我有使用另一个Spring启动授权服务器的spring boot rest api（resources），我已经将Swagger配置添加到资源应用程序中，以便为其余的API获得一个漂亮而快速的文档/测试平台。我的Swagger配置如下所示：

@Configuration
@EnableSwagger2
public class SwaggerConfig {    

    @Autowired
    private TypeResolver typeResolver;

    @Value("${app.client.id}")
    private String clientId;
    @Value("${app.client.secret}")
    private String clientSecret;
    @Value("${info.build.name}")
    private String infoBuildName;

    public static final String securitySchemaOAuth2 = "oauth2";
    public static final String authorizationScopeGlobal = "global";
    public static final String authorizationScopeGlobalDesc = "accessEverything";

    @Bean
    public Docket api() { 

        List<ResponseMessage> list = new java.util.ArrayList<ResponseMessage>();
        list.add(new ResponseMessageBuilder()
                .code(500)
                .message("500 message")
                .responseModel(new ModelRef("JSONResult«string»"))
                .build());
        list.add(new ResponseMessageBuilder()
                .code(401)
                .message("Unauthorized")
                .responseModel(new ModelRef("JSONResult«string»"))
                .build());


        return new Docket(DocumentationType.SWAGGER_2)  
          .select()                                  
          .apis(RequestHandlerSelectors.any())              
          .paths(PathSelectors.any())     
          .build()
          .securitySchemes(Collections.singletonList(securitySchema()))
          .securityContexts(Collections.singletonList(securityContext()))
          .pathMapping("/")
          .directModelSubstitute(LocalDate.class,String.class)
          .genericModelSubstitutes(ResponseEntity.class)
          .alternateTypeRules(
              newRule(typeResolver.resolve(DeferredResult.class,
                      typeResolver.resolve(ResponseEntity.class, WildcardType.class)),
                  typeResolver.resolve(WildcardType.class)))
          .useDefaultResponseMessages(false)
          .apiInfo(apiInfo())
          .globalResponseMessage(RequestMethod.GET,list)
          .globalResponseMessage(RequestMethod.POST,list);
    }


    private OAuth securitySchema() {

        List<AuthorizationScope> authorizationScopeList = newArrayList();
        authorizationScopeList.add(new AuthorizationScope("global", "access all"));

        List<GrantType> grantTypes = newArrayList();
        final TokenRequestEndpoint tokenRequestEndpoint = new TokenRequestEndpoint("http://server:port/oauth/token", clientId, clientSecret);
        final TokenEndpoint tokenEndpoint = new TokenEndpoint("http://server:port/oauth/token", "access_token");
        AuthorizationCodeGrant authorizationCodeGrant = new AuthorizationCodeGrant(tokenRequestEndpoint, tokenEndpoint);

        grantTypes.add(authorizationCodeGrant);

        OAuth oAuth = new OAuth("oauth", authorizationScopeList, grantTypes);

        return oAuth;
    }


    private SecurityContext securityContext() {
        return SecurityContext.builder().securityReferences(defaultAuth())
                .forPaths(PathSelectors.ant("/api/**")).build();
    }

    private List<SecurityReference> defaultAuth() {

        final AuthorizationScope authorizationScope =
                new AuthorizationScope(authorizationScopeGlobal, authorizationScopeGlobalDesc);
        final AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return Collections
                .singletonList(new SecurityReference(securitySchemaOAuth2, authorizationScopes));
    }



    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title(“My rest API")
                .description(" description here … ”)
                .termsOfServiceUrl("https://www.example.com/")
                .contact(new Contact(“XXXX XXXX”,
                                     "http://www.example.com", “xxxx@example.com”))
                .license("license here”)
                .licenseUrl("https://www.example.com")
                .version("1.0.0")
                .build();
    }

}

我从授权服务器获取访问令牌的方法是使用http POST到此链接，并在clientid / clientpass的标头中使用基本授权：

http://server:port/oauth/token?grant_type=password&username=<username>&password=<password>

响应类似于：

{
    "access_token": "e3b98877-f225-45e2-add4-3c53eeb6e7a8",
    "token_type": "bearer",
    "refresh_token": "58f34753-7695-4a71-c08a-d40241ec3dfb",
    "expires_in": 4499,
    "scope": "read trust write"
}

在Swagger UI中我可以看到一个授权按钮，它会打开一个对话框来发出授权请求，但它无法正常工作并指示我链接如下，

http://server:port/oauth/token?response_type=code&redirect_uri=http%3A%2F%2Fserver%3A8080%2Fwebjars%2Fspringfox-swagger-ui%2Fo2c.html&realm=undefined&client_id=undefined&scope=global%2CvendorExtensions&state=oauth

我在这里缺少什么？

Swagger UI has an Authorisation button

8个月后，最后在Swagger UI中支持密码流，这是最终的代码和设置，对我有用：

1）Swagger配置：

package com.example.api;


import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.annotation.RequestMethod;
import springfox.documentation.schema.ModelRef;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.AuthorizationScope;
import springfox.documentation.service.Contact;
import springfox.documentation.service.GrantType;
import springfox.documentation.service.OAuth;
import springfox.documentation.service.ResourceOwnerPasswordCredentialsGrant;
import springfox.documentation.service.ResponseMessage;
import springfox.documentation.service.SecurityReference;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.builders.ResponseMessageBuilder;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spi.service.contexts.SecurityContext;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger.web.ApiKeyVehicle;
import springfox.documentation.swagger.web.SecurityConfiguration;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import java.util.Collections;
import java.util.List;

import static com.google.common.collect.Lists.*;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Value("${app.client.id}")
    private String clientId;
    @Value("${app.client.secret}")
    private String clientSecret;
    @Value("${info.build.name}")
    private String infoBuildName;

    @Value("${host.full.dns.auth.link}")
    private String authLink;

    @Bean
    public Docket api() {

        List<ResponseMessage> list = new java.util.ArrayList<>();
        list.add(new ResponseMessageBuilder().code(500).message("500 message")
                .responseModel(new ModelRef("Result")).build());
        list.add(new ResponseMessageBuilder().code(401).message("Unauthorized")
                .responseModel(new ModelRef("Result")).build());
        list.add(new ResponseMessageBuilder().code(406).message("Not Acceptable")
                .responseModel(new ModelRef("Result")).build());

        return new Docket(DocumentationType.SWAGGER_2).select().apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any()).build().securitySchemes(Collections.singletonList(securitySchema()))
                .securityContexts(Collections.singletonList(securityContext())).pathMapping("/")
                .useDefaultResponseMessages(false).apiInfo(apiInfo()).globalResponseMessage(RequestMethod.GET, list)
                .globalResponseMessage(RequestMethod.POST, list);



    }

    private OAuth securitySchema() {

        List<AuthorizationScope> authorizationScopeList = newArrayList();
        authorizationScopeList.add(new AuthorizationScope("read", "read all"));
        authorizationScopeList.add(new AuthorizationScope("trust", "trust all"));
        authorizationScopeList.add(new AuthorizationScope("write", "access all"));

        List<GrantType> grantTypes = newArrayList();
        GrantType creGrant = new ResourceOwnerPasswordCredentialsGrant(authLink+"/oauth/token");

        grantTypes.add(creGrant);

        return new OAuth("oauth2schema", authorizationScopeList, grantTypes);

    }

    private SecurityContext securityContext() {
        return SecurityContext.builder().securityReferences(defaultAuth()).forPaths(PathSelectors.ant("/user/**"))
                .build();
    }

    private List<SecurityReference> defaultAuth() {

        final AuthorizationScope[] authorizationScopes = new AuthorizationScope[3];
        authorizationScopes[0] = new AuthorizationScope("read", "read all");
        authorizationScopes[1] = new AuthorizationScope("trust", "trust all");
        authorizationScopes[2] = new AuthorizationScope("write", "write all");

        return Collections.singletonList(new SecurityReference("oauth2schema", authorizationScopes));
    }

    @Bean
    public SecurityConfiguration securityInfo() {
        return new SecurityConfiguration(clientId, clientSecret, "", "", "", ApiKeyVehicle.HEADER, "", " ");
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder().title("My API title").description("")
                .termsOfServiceUrl("https://www.example.com/api")
                .contact(new Contact("Hasson", "http://www.example.com", "hasson@example.com"))
                .license("Open Source").licenseUrl("https://www.example.com").version("1.0.0").build();
    }

}

2）在POM中使用这个Swagger UI版本2.7.0：

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.7.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.7.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-bean-validators</artifactId>
        <version>2.7.0</version>
    </dependency>

3）在application.properties中添加以下属性：

host.full.dns.auth.link=http://oauthserver.example.com:8081
app.client.id=test-client
app.client.secret=clientSecret
auth.server.schem=http

4）在授权服务器中添加一个CORS过滤器：

package com.example.api.oauth2.oauth2server;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**
 * Allows cross origin for testing swagger docs using swagger-ui from local file
 * system
 */
@Component
public class CrossOriginFilter implements Filter {
    private static final Logger log = LoggerFactory.getLogger(CrossOriginFilter.class);

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

        // Called by the web container to indicate to a filter that it is being
        // placed into service.
        // We do not want to do anything here.
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain)
            throws IOException, ServletException {

        log.info("Applying CORS filter");
        HttpServletResponse response = (HttpServletResponse) resp;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "0");
        chain.doFilter(req, resp);
    }

    @Override
    public void destroy() {

        // Called by the web container to indicate to a filter that it is being
        // taken out of service.
        // We do not want to do anything here.
    }
}

如果您使用这些设置运行，您将获得链接http://apiServer.example.com:8080/swagger-ui.html#/中的授权按钮（如果您在8080上运行），如下所示：

enter image description here

然后当您点击授权按钮时，您将获得以下对话框，添加您的用户名/密码的数据以及客户端ID和客户端密码，类型必须是请求正文，我不知道为什么但是这个是什么适用于我，虽然我认为它应该是基本的auth，因为这是客户端密码的发送方式，无论如何这是Swagger-ui如何使用密码流和所有的API端点再次工作。快乐大摇大摆!!! :)

我不确定您的问题是什么，但授权按钮对我来说是swagger版本2.7.0，但我必须手动获取JWT令牌。

首先我为auth令牌命中，然后我插入如下的令牌，

enter image description here

这里的关键是我的令牌是JWT，我无法在 Bearer **之后插入令牌值并将** api_key 名称更改为授权并且我实现了使用以下Java配置，

@Bean
    public SecurityConfiguration securityInfo() {
        return new SecurityConfiguration(null, null, null, null, "", ApiKeyVehicle.HEADER,"Authorization",": Bearer");
    }

关于范围分隔符的招摇似乎存在一个错误，默认情况下为：。在我的配置中，我尝试将其修改为: Bearer，但这没有发生，所以我必须在UI上输入它。

答案 2 :(得分：0)

目前使用oAuth2授权的最佳方法是使用Swagger编辑器，我在Docker中快速安装了Swagger Editor（来自here），然后使用import参数下载API JSON描述符（您的API）应该包括CORS过滤器），然后我可以获得Swagger文档和一个界面，我可以使用curl，postman或Firefox rest client添加令牌。

我现在使用的链接看起来像这样

http://docker.example.com/#/?import=http://mywebserviceapi.example.com:8082/v2/api-docs&no-proxy

Swagger编辑器中输入令牌的界面如下所示：

答案 3 :(得分：0)

这是swagger-ui 2.6.1上的一个错误，它每次都会发送vendorExtensions范围。这导致请求超出范围，导致拒绝请求。由于swagger无法获取访问令牌，因此无法通过oauth2

升级maven应该可以解决问题。最低版本应为2.7.0
