通过OpenFeign远程调用同局域网的其他接口

需要的依赖

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>
        <!-- feign httpclient -->
        <dependency>
            <groupId>io.github.openfeign</groupId>
            <artifactId>feign-httpclient</artifactId>
        </dependency>

项目结构

关于Client的编写

@Repository 
@FeignClient(contextId = "PayClient", value = "ruoyi-pay",url = "192.168.31.47:9206")
public interface PayClient {
    @GetMapping("/pay/chargeable/list?pageNum=1&pageSize=10")
    TableDataInfo list(@RequestBody PayChargeable payChargeable);
}

拦截器的编写

@Component
public class FeignInterceptor implements RequestInterceptor {
    @Override
    public void apply(RequestTemplate requestTemplate) {
        RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
        if(requestAttributes != null){
            HttpServletRequest request = ((ServletRequestAttributes) requestAttributes).getRequest();
            String authorization = request.getHeader("Access-Control-Allow-Origin");
            requestTemplate.header("Access-Control-Allow-Origin", "*");

        }
    }
}

作用: 将token放入请求头中

编写Controller

先将Client自动注入
