使用Quarkus休息数据时，Panache如何从@PrePersist中的请求标头访问用户名 [英] When using Quarkus rest data Panache how to access username from request header in @PrePersist

问题描述

我正在尝试记录修改实体的用户.反向代理在请求标头中设置用户名.

I am trying to log the user that modified the entity. The reverse proxy is setting the user name in the request header.

当使用Rest Panache公开JAX-RS CRUD时，如何从独立的类中读取请求和标头

How can the request and headers be read from an independent class when rest Panache is used to expose JAX-RS CRUD

下面是我尝试过的示例，但我得到的是null或null指针是错误提示

below an example of what I tried but I am getting null or null pointer exep

package org.acme.manrest;

import javax.enterprise.context.RequestScoped;
import javax.persistence.PrePersist;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.HeaderParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.HttpHeaders;

import org.acme.jpa.TBusiness;
import org.jboss.logging.Logger;

@RequestScoped
public class HeaderValue {
  private static final Logger LOG = Logger.getLogger(HeaderValue.class);

  @Context
  HttpServletRequest request;

  public HttpServletRequest getRequest() {
    return request;
  }

  @Context
  HttpHeaders httpHeaders;

  @HeaderParam("x-remote-user")
  String userName;

  public String getUserName() {
    LOG.info("xxx: " + getRequest().getHeader("x-remote-user"));
    LOG.info("userName: " + userName);
    LOG.info("getUserName2: " + getUserName2());
    LOG.info("getUserName3: " + getUserName3());
    return userName;
  }

  public String getUserName2() {
    return httpHeaders.getRequestHeader("x-remote-user").get(0);
  }

  public String getUserName3() {
    LOG.info("getUserName from class " + request.getHeader("x-remote-user"));
    return request.getHeader("x-remote-user");
  }

  @PrePersist
  void onPrePersist(TBusiness myEntity) {
    LOG.info("getUserName: " + userName);

    myEntity.createdBy = userName;
    myEntity.updatedBy = userName;
  }

}

是否可以在Quarkus中切换到JWT并使用JWT RBAC?

Could switching to JWT and using JWT RBAC in Quarkus be a workaround?

推荐答案

通过添加underwow依赖关系使此功能起作用:

got this to work by adding undertow dependency :

    <dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-undertow</artifactId>
    </dependency>

然后在 PrePersist 方法下面创建的 EntityListener 类中:

then in an EntityListener class created below PrePersist method:

@RequestScoped
// @Path("api/v1/Header")
public class AuditingEntityListener {
  private static final Logger LOG = Logger.getLogger(AuditingEntityListener.class);

  // Inject the bean so that Quarkus does not remove it at build time (IMPORTANT)
  @Inject
  HttpServletRequest requestNotUsed;

  @PrePersist
  void onPrePersist(TBusiness myEntity) {
    HttpServletRequest HSR = CDI.current().select(HttpServletRequest.class).get();
    LOG.info("HSR getRequestHeader user: " + HSR.getHeader("x-remote-user"));
  }
}

在Quarkus中使用JWT RBAC也可以:

using JWT RBAC in Quarkus also works:

  @PrePersist
  void onPrePersist(TBusiness myEntity) {
    JsonWebToken context = CDI.current().select(JsonWebToken.class).get();
    LOG.info("context: " + context.getClaim("preferred_username"));
  }
