从另一个容器调用 API 时出错"cURL error 7: Failed to connect to localhost port"

Question

我正在对一个拥有多个不同服务的应用程序进行Docker Compose文件，我使用Docker Composer文件为所有服务实现了这个Single Docker-Compose.yml文件，为每个服务实现了一个Dockerfile。

1. 前端(角度([http://localhost:4200]
2. 后端(PHP([http://localhost:80]
3. 后端数据库(Mysql(
4. 集成服务(NodeJS([http://localhost:4433]
5. 集成服务数据库(MongoDB(
6. 身份验证层(NodeJS([http://localhost:4454]
7. 身份验证层数据库(Mysql(

到目前为止，我已经成功地将所有这些服务容器化；后端(PHP("；容器试图从"调用API；集成服务(NodeJS("；则抛出错误CCD_ 1。
