我正在尝试从UI容器中调用API。
这是调用的URL：http://api:3000/api/search?query=ihpone&page=1&minPrice=0&maxPrice=9999
我收到了ERR_NAME_NOT_RESOLVED错误。
有人可以帮助我吗？如何解决我的问题？如何从UI容器向API容器发出请求？

当您在浏览器中打开您的UI应用程序时，实际上是将其下载到主机（安装了Docker的计算机）上，然后发出API调用。
因此，在您的示例中，您需要将UI应用程序的配置中的URL设置为：localhost:3000，而不是api:3000。
- localhost:3000 - 用于从主机中的Docker容器中访问应用程序。
- api:3000 - 用于从另一个Docker容器中的Docker容器中访问应用程序。
英文:
When you're opening your UI application on browser you're actually downloading it to host (your machine where docker is installed) and then you're making a call to API.
So in your example you need to set url in your UI application's configuration to be: localhost:3000 instead of api:3000
- localhost:3000 - is to hit an app in a docker container from a host.
- api:3000 - is to hit an app in a docker container from another docker container.
