spring cloud oauth2 feign 遇到的坑

关于oauth2相关的内容这里不重复描述，在春天的云中在管理内部美国石油学会(美国石油协会)时鉴权相信有很多人会有疑问，这里描述两种比较低的的用法，由于公司内部使用的是阿里云贴敷术这里仅仅是记录一下，如果有更好的用法在请赐教，不喜勿喷！

客户端模式

提供三方jar包

　　这里需要抽一个冲突包，需要用到假装的为服务端直接利用专家模式引入假装即可

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

/** * The interface Mdc product feign api. * @author paascloud.net@gmail.com */@FeignClient(value = "paascloud-provider-mdc", configuration = OAuth2FeignAutoConfiguration.class, fallback = MdcProductFeignHystrix.class)public interface MdcProductFeignApi {    /**     * Update product stock by id int.     *     * @param productDto the product dto     *     * @return the int     */    @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.OAuth2ClientProperties;import com.paascloud.security.core.properties.SecurityProperties;import org.apache.commons.lang3.ArrayUtils;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.security.oauth2.config.annotation.builders.InMemoryClientDetailsServiceBuilder;import org.springframework.security.oauth2.provider.ClientDetails;import org.springframework.security.oauth2.provider.ClientDetailsService;import org.springframework.security.oauth2.provider.ClientRegistrationException;import org.springframework.stereotype.Component;import javax.annotation.PostConstruct;/** * The class Rest client details service. * * @author paascloud.net @gmail.com */@Component("restClientDetailsService")public class RestClientDetailsServiceImpl implements ClientDetailsService {    private ClientDetailsService clientDetailsService;    @Autowired    private SecurityProperties securityProperties;    /**     * Init.     */    @PostConstruct    public void init() {        InMemoryClientDetailsServiceBuilder builder = new InMemoryClientDetailsServiceBuilder();        if (ArrayUtils.isNotEmpty(securityProperties.getOauth2().getClients())) {            for (OAuth2ClientProperties client : securityProperties.getOauth2().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();        }    }    /**     * Load client by client id client details.     *     * @param clientId the client id     *     * @return the client details     *     * @throws ClientRegistrationException the client registration exception     */    @Override    public ClientDetails loadClientByClientId(String clientId) throws ClientRegistrationException {        return  clientDetailsService.loadClientByClientId(clientId);    }}

bootstrap.yml配置

security:    oauth2:      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auth2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 OAuth2ClientContext context;@Override    public void apply(RequestTemplate template) {        if(context.getAccessToken() != null && context.getAccessToken().getValue() != null && OAuth2AccessToken.BEARER_TYPE.equalsIgnoreCase(context.getAccessToken().getTokenType()) ){            template.header("Authorization", String.format("%s %s", OAuth2AccessToken.BEARER_TYPE, context.getAccessToken().getValue()));        }    }

spring cloud微服务增加oauth2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

/** * 发送FeignClient设置Header信息. * http://www.itmuch.com/spring-cloud-sum/hystrix-threadlocal/ * Hystrix传播ThreadLocal对象 */@Componentpublic class TokenFeignClientInterceptor implements RequestInterceptor {  /**   * token放在请求头.   *   * @param requestTemplate 请求参数   */  @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
