Feign调用携带Token

---

远程调用携带Token令牌，请求携带请求头信息。

OpenFeign调用微服务时RequestInterceptor或@RequestHeader传递http请求头信息

1、 触发拦截器

// 通过配置configuration进行触发拦截器.
@FeignClient(name = "admin-service", url = "${feign.property.admin-url}",
        configuration = SecurityInterceptor.class)
@Component
public interface AdminFeign {
    /**
     * 已读新闻
     *
     * @param id       新闻 ID
     * @param platform 平台
     * @return {@link Result}<{@link Void}>
     */
    @PostMapping("/sociality/news/{id}/read/platform/{platform}")
    Result<Void> newsRead(@PathVariable(value = "id") Long id,
                          @PathVariable(value = "platform") String platform);
}


// 方式2：自定义拦截器
import feign.RequestInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @Description : Feign拦截器
 * @Author : LiYan
 * @CreateTime : 2023/12/21 18:29
 */
@Configuration
public class FeignConfig {

    /**
     * 注入自定义的拦截器
     */
    @Bean
    public RequestInterceptor requestInterceptor() {
        return new SecurityInterceptor();
    }
}

2、配置拦截器

import feign.RequestInterceptor;
import feign.RequestTemplate;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

/**
 * @Description :
 * @Author : LiYan
 * @CreateTime : 2023/12/21 16:26
 */
public class SecurityInterceptor implements RequestInterceptor {

    @Override
    public void apply(RequestTemplate requestTemplate) {
        RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
        if (null!= requestAttributes) {
            HttpServletRequest request = ((ServletRequestAttributes) requestAttributes).getRequest();
            requestTemplate.header("access-token", request.getHeader("access-token"));
        }
    }
}
