3.3. 故障排除服务

流程

1. 要跟踪 HTTP 请求和响应，OpenShift Serverless Logic 通过设置以下属性来使用 Apache HTTP 客户端：

   # Turning HTTP tracing on
   quarkus.log.category."org.apache.http".level=DEBUG

   Copy to Clipboard Toggle word wrap

2. 在应用程序的 application.properties 文件中添加以下配置，以打开 Apache HTTP 客户端的调试：

   quarkus.log.category."org.apache.http".level=DEBUG

3. 重启应用程序以传播日志配置更改。

4. 重启后，检查 HTTP 请求追踪的日志。

5. 在请求日志后检查 HTTP 响应追踪的日志。

   追踪的 HTTP 响应的日志示例
