You could use the the IP address of the host machine from within you container in order to send requests to the host machine.您可以使用容器内的主机 IP 地址向主机发送请求。
A better solution, however, would be to use --add-host=host.docker.internal:host-gateway or但是，更好的解决方案是使用--add-host=host.docker.internal:host-gateway或
extra_hosts:
- host.docker.internal:host-gateway
where host.docker.internal is then the host name of the host network inside your docker container.其中host.docker.internal是 docker 容器内的主机网络的主机名。 This name can of course be changed to your liking.此名称当然可以根据您的喜好更改。
