记录传出 JBoss EAP 7/RESTEasy 请求

Question

有没有办法记录使用 ResteasyClientBuilder 创建的客户端发出的传出 HTTP 请求？

我们的一个服务向另一个服务发出的请求有问题，我们想查看 RESTEasy/JBoss EAP 7 正在创建/发送的实际 HTTP 请求的标头、正文等。

Answer 1

Resteasy 客户端使用的是 Apache HTTP 客户端。 您可以为org.apache.http package 设置级别DEBUG以查看日志：

<logger category="org.apache.http" use-parent-handlers="true">
    <level name="DEBUG"/>
</logger>

Answer 2

如果您希望在下面记录来自客户的请求

Client client = ClientBuilder.newClient();
    String url = "https://translate.googleapis.com/translate_a/single?client=gtx&sl=" + "en" + "&tl=" + "hi"
            + "&dt=t&q=" + URLEncoder.encode(msg);
    client.register(new LoggingFilter());

这里是client.register（new LoggingFilter（））; 为您记录，您可以将记录器传递给它。

同样可以通过编辑web.xml来完成，如下所示

    <web-app>
  <display-name>Archetype Created Web Application</display-name>
  <servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

    <init-param>
         <param-name>com.sun.jersey.spi.container.ContainerRequestFilters</param-name>
         <param-value>com.sun.jersey.api.container.filter.LoggingFilter</param-value>
     </init-param>
     <init-param>
         <param-name>com.sun.jersey.spi.container.ContainerResponseFilters</param-name>
         <param-value>com.sun.jersey.api.container.filter.LoggingFilter</param-value>
     </init-param>

 <init-param>
      <param-name>javax.ws.rs.Application</param-name>
      <param-value>com.webspherenotes.rest.ContactApplication</param-value>
    </init-param>

  </servlet>
  <servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>

</web-app>
