spring cloud oauth3 feign 遇到的坑

关于oauth3相关的内容这里不重复描述，在spring cloud中在管理内部api时鉴权相信有很多人会有疑问，这里描述两种比较low的用法。

客户端模式

提供三方jar包

这里需要抽一个jar包,需要用到feign的为服务端直接利用maven模式引入feign即可

<dependencies>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-feign</artifactId>        </dependency>        <dependency>            <groupId>com.netflix.feign</groupId>            <artifactId>feign-okhttp</artifactId>            <version>8.18.0</version>        </dependency>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-oauth3</artifactId>        </dependency>    </dependencies>

核心类

• CustomHystrixConcurrencyStrategy.java

• Oauth3ClientProperties.java

• OAuth3FeignAutoConfiguration.java

• OAuth3FeignRequestInterceptor.java

调用端配置

引入maven依赖

<dependency>            <groupId>com.liuzm.paascloud.common</groupId>            <artifactId>paascloud-security-feign</artifactId>            <version>1.0-SNAPSHOT</version></dependency>

@FeignClient加入configuration属性

@FeignClient(value = "paascloud-provider-mdc", configuration = OAuth3FeignAutoConfiguration.class, fallback = MdcProductFeignHystrix.class)public interface MdcProductFeignApi {        @RequestMapping(value = "/api/product/updateProductStockById", method = RequestMethod.POST)    int updateProductStockById(@RequestBody ProductDto productDto);}

认证服务器配置

@Override    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {        clients.withClientDetails(restClientDetailsService);    }

package com.paascloud.provider.security;import com.paascloud.security.core.properties.OAuth3ClientProperties;import com.paascloud.security.core.properties.SecurityProperties;import org.apache.commons.lang3.ArrayUtils;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.security.oauth3.config.annotation.builders.InMemoryClientDetailsServiceBuilder;import org.springframework.security.oauth3.provider.ClientDetails;import org.springframework.security.oauth3.provider.ClientDetailsService;import org.springframework.security.oauth3.provider.ClientRegistrationException;import org.springframework.stereotype.Component;import javax.annotation.PostConstruct;@Component("restClientDetailsService")public class RestClientDetailsServiceImpl implements ClientDetailsService {    private ClientDetailsService clientDetailsService;    @Autowired    private SecurityProperties securityProperties;        @PostConstruct    public void init() {        InMemoryClientDetailsServiceBuilder builder = new InMemoryClientDetailsServiceBuilder();        if (ArrayUtils.isNotEmpty(securityProperties.getOauth3().getClients())) {            for (OAuth3ClientProperties client : securityProperties.getOauth3().getClients()) {                builder.withClient(client.getClientId())                        .secret(client.getClientSecret())                        .authorizedGrantTypes("refresh_token", "password", "client_credentials")                        .accessTokenValiditySeconds(client.getAccessTokenValidateSeconds())                        .refreshTokenValiditySeconds(2592000)                        .scopes(client.getScope());            }        }        try {            clientDetailsService = builder.build();        } catch (Exception e) {            e.printStackTrace();        }    }        @Override    public ClientDetails loadClientByClientId(String clientId) throws ClientRegistrationException {        return  clientDetailsService.loadClientByClientId(clientId);    }}

bootstrap.yml配置

security:    oauth3:      tokenStore: jwt      clients[0]:        clientId: paascloud-client-uac        clientSecret: paascloudClientSecret        accessTokenValidateSeconds: 7200        scope: "*"      clients[1]:        clientId: paascloud-browser        clientSecret: paascloudClientSecret        accessTokenValidateSeconds: 7200        scope: "*"      clients[2]:        clientId: paascloud-client-gateway        clientSecret: paascloudClientSecret        accessTokenValidateSeconds: 7200        scope: "*"      clients[3]:        clientId: paascloud-client-zipkin        clientSecret: paascloudClientSecret        accessTokenValidateSeconds: 7200        scope: "*"      clients[4]:        clientId: paascloud-client-mdc        clientSecret: paascloudClientSecret        accessTokenValidateSeconds: 7200        scope: "*"      clients[5]:        clientId: paascloud-client-omc        clientSecret: paascloudClientSecret        accessTokenValidateSeconds: 7200        scope: "*"      clients[6]:        clientId: paascloud-client-opc        clientSecret: paascloudClientSecret        accessTokenValidateSeconds: 7200        scope: "*"

到此客户端模式配置完成!

基于spring security

开放权限,利用url规范来规划客户端的url不通过auth3鉴权,这里唯一的区别是在feign拦截器里处理的逻辑改一下，代码如下

@Autowiredprivate OAuth3ClientContext context;@Override    public void apply(RequestTemplate template) {        if(context.getAccessToken() != null && context.getAccessToken().getValue() != null && OAuth3AccessToken.BEARER_TYPE.equalsIgnoreCase(context.getAccessToken().getTokenType()) ){            template.header("Authorization", String.format("%s %s", OAuth3AccessToken.BEARER_TYPE, context.getAccessToken().getValue()));        }    }

spring cloud微服务增加oauth3权限后 feign调用报null

在授权服务里，用户通过用户名密码，或者手机和验证码等方式登陆之后，在http头里会有授权的标识，在客户端调用时，需要添加当时有效的token才可以正常访问被授权的页面。

Content-Type:application/jsonAuthorization:Bearer d79c064c-8675-4047-a119-fac692e447e8

而在业务层里，服务与服务之间使用feign来实现调用，而授权的代码我们可以通过拦截器实现，在feign请求之前，把当前服务的token添加到目标服务的请求头就可以了

一般是这样实现的

@Componentpublic class TokenFeignClientInterceptor implements RequestInterceptor {    @Override  public void apply(RequestTemplate requestTemplate) {    RequestAttributes requestAttributes = RequestContextHolder.currentRequestAttributes();    if (requestAttributes != null) {      HttpServletRequest request = ((ServletRequestAttributes) requestAttributes).getRequest();      requestTemplate.header("Authorization", request.getHeader("Authorization"));    }  }}

上面的拦截器代码没有什么问题，也很好理解，但事实上，当你的feign开启了hystrix功能，如果开启了，需要把hystrix的策略进行修改，默认是THREAD的，这个级别时ThreadLocal是空的，所以你的授权不能传给feign的拦截器.

hystrix:     command:         default:             execution:                 isolation:                     strategy: SEMAPHORE
