Question

我有用Angular 7编写的Web应用程序，它具有Proxy和.NET Core 2.2作为WebAPI。我的问题是本地一切正常，但是我无法从Codker容器内的WebAPI发出任何请求，因为我得到了

craftsmen.client_1  | [HPM] Rewriting path from "/api//CraftOffer/GetManyWithFilters/0/5?category=0" to "/Public//CraftOffer/GetManyWithFilters/0/5?category=0"
craftsmen.client_1  | [HPM] GET /api//CraftOffer/GetManyWithFilters/0/5?category=0 ~> https://localhost:5000
craftsmen.client_1  | [HPM] Rewriting path from "/api/CraftOffer/GetCategories" to "/Public/CraftOffer/GetCategories"
craftsmen.client_1  | [HPM] GET /api/CraftOffer/GetCategories ~> https://localhost:5000
craftsmen.client_1  | [HPM] Error occurred while trying to proxy request /Public//CraftOffer/GetManyWithFilters/0/5?category=0 from localhost:4200 to https://localhost:5000 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)
craftsmen.client_1  | [HPM] Error occurred while trying to proxy request /Public/CraftOffer/GetCategories from localhost:4200 to https://localhost:5000 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors)

如何能够从Docker容器内的客户端发出WebAPI请求？

我尝试过：
-更改以将proxy.conf.json中的目标更改为https://craftsmen.webapi:5000
-将ASPNETCORE_URLS从http更改为https
-更改为将proxy.conf.json中的目标更改为https://127.0.0.1:5000

当前proxy.conf.json

{
    "/api/*": {
      "target": "https://localhost:5000",
      "secure": false,
      "logLevel": "debug",
      "changeOrigin": true,
      "pathRewrite": {"api" : "Public"}
    }
  }

我希望能够从Angular Client向WebApi发出成功的请求

您不能在docker容器内使用localhost。您可以使用：

本地ip
公共ip
公共领域

肮脏的解决方案：使用ip代替localhost

在使用docker-compose时，所有docker应用都位于同一主机中，因此请在linux shell中执行此操作：

hostname -I

要获取ip并将其用于 proxy.conf.json 而不是localhost

还要强调： docker-compose 蚂蚁 docker网络仅用于开发。
