Question

我是新手。我构建并部署到github页面，但是我的REST api标注均无法正常工作。我在heroku上部署了一个节点后端。这些API调用是在ngAfterViewInit（）方法内部执行的。我已将代理添加到后端节点表达服务器。这是我的angular.json

        }
      }
    }
  },
  "defaultProject": "musicsite-test2",
  "cli": {
    "analytics": false
  }
}

这是我的代理配置文件

{
    "/api/*": {
      "target": "https://village-voice-server.herokuapp.com",
      "secure": false,
      "logLevel": "debug",
      "changeOrigin": true
    }
  }

proxy conf文件位于/ src文件夹中。我究竟做错了什么？还有一个问题，我可以将我的Angular项目上传到由hostinger（网络主机）提供的普通网络服务器上吗？

第一件事！您选择了哪个选项来生成角度构建。如果通常由ng buil --prod完成，那么不用担心，但是使用```@ angular / universal之类的库将不会轻松地运行您的应用程序。对于此选项，您需要将其部署到提供node.js以便进行预渲染或服务器端渲染Web应用程序的平台。

现在，我假设您具有简单的角度构建（通过``ng build --prod”）。您需要检查开发过程中是否在运行应用程序以及将heroku作为节点后端。

下一个问题是向您的节点应用程序添加代理的需求是什么？如果您的节点api工作正常，甚至可以从其他服务器作为服务器，那么我认为没有任何必要。

最后，您询问是否要像托管服务商一样将其托管。显然，它甚至可以部署在静态托管平台中。但是缺点是基于javascript渲染。因此，这里不可能进行搜索引擎优化。

这就是为什么角度生成@angular/universal的原因。在这里，使用node，您可以得到想要的任何东西。当然，搜索引擎优化也是如此。
