如何将 RequestHeader 与执行器端点一起使用? [英] How can I use RequestHeader with actuator endpoint?

问题描述

我已经自定义了我的执行器/信息端点，我想使用标头中的信息来授权对另一个服务的 RestTemplate 调用.

I have customized my actuator/info endpoint and I want to use information from the header to authorize a RestTemplate call to another service.

我在这里实现了 InfoContributor:https://www.baeldung.com/spring-boot-info-actuator-自定义

I am implementing the InfoContributor as here: https://www.baeldung.com/spring-boot-info-actuator-custom

我想在 contribute() 方法中接受请求标头.对于任何用户定义的 REST 端点，我可以定义一个 @RequestHeader 参数和访问标头.

I want to accept request headers in the contribute() method. For any user defined REST endpoint, I can define a @RequestHeader parameter and access headers.

但不幸的是，InfoContributor 的 contribute() 方法只接受一个参数.

But unfortunately, the InfoContributor's contribute() method takes only one parameter.

如何访问 contribute() 方法中的请求标头?

How can I access a request header inside the contribute() method?

推荐答案

• 您可以将 HttpServletRequest 自动连接到您的 InfoContributor
• You can autowire HttpServletRequest into your InfoContributor

    import javax.servlet.http.HttpServletRequest;

    @Component
    public class Custom implements InfoContributor {

       @Autowired
       private HttpServletRequest request;

       @Override
       public void contribute(Info.Builder builder) {
          ...
          request.getHeader("your header");
          ...
       }
    }

• 或者你可以使用RequestContextHolder来获取它

@Component
public class Custom implements InfoContributor {

    @Override
    public void contribute(Info.Builder builder) {
        ...
        HttpServletRequest request = 
           ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes())
                        .getRequest();
        request.getHeader("your header");
       ...
    }
}
