OpenFeign服務調用時攜帶Token

OpenFeign服務調用時攜帶Token：

　　場景：眾所周知，OpenFigen主要的作用是替我們發送Http請求的，那么在有些場景中，需要在OpenFiegn中攜帶Token到另一個服務去，需要配置一個Fegin的配置類完成此操作

• 第一步創建FeginClient的配置類

package cn.woniu.yyyservice.nacosconfig;

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

import javax.servlet.http.HttpServletRequest;

/**
 * Created with IntelliJ IDEA.
 *
 * @Author: hui
 * @Date: 2021/12/05/17:33
 * @Description:
 */
@Configuration
public class FeignConfiguration implements RequestInterceptor {

    @Override
    public void apply(RequestTemplate requestTemplate) {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        requestTemplate.header("jwt-Token", request.getHeader("jwt-Token"));
    }

}

•  在@FeginClient注解添加Configuration

package cn.woniu.yyyservice.client;

import cn.woniu.yyyservice.nacosconfig.FeignConfiguration;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created with IntelliJ IDEA.
 *
 * @Author: hui
 * @Date: 2021/12/05/15:49
 * @Description:
 */
@FeignClient(name = "xxx-service", fallback = XxxFallBackServiceClientImpl.class, configuration = FeignConfiguration.class)
public interface XxxServiceClient {

    @RequestMapping("/all-can-do")
    public String demo7();

    @RequestMapping("/")
    public String index();
}
