当我尝试访问Docker容器外部时,我得到了空数据,并出现了下面提到的错误。我在Docker容器内使用curl和wget命令没有任何问题。容器基于Angular JS镜像。
“localhost didn't send data. ERR_EMPTY_RESPONSE”和“curl:(52)来自服务器的空答复”
请帮帮我。
对不起!忘记发布实际代码。这里是我的Dockerfile和package.json文件。

当HTTP客户端(如Web浏览器(或在本例中为curl))发送HTTP请求时,服务器需要客户端的IP地址,以便知道将响应发送到何处。当您运行本地开发服务器时,它会检查该IP地址,甚至不会响应不是来自www.example.com的请求127.0.0.1(localhost)。这可以防止网络上的其他人(比如,坐在同一家星巴克里)使用开发服务器作为入侵你的机器的一种方式。
当您在访客容器或VM中运行开发服务器,并在主机上运行客户端(curl)时,服务器会看到不同的IP地址,并拒绝响应。大多数服务器允许您指定有效客户端IP地址的掩码。0.0.0.0意味着fugetaboutit,接受所有客户端IP。它让保镖晚上休息。

我建议的理想方法是在创建时将主机IP地址绑定到容器。您不应该从Docker文件启动应用程序的运行。创建容器,与主机绑定并编写脚本来 Boot 应用程序
你可以这样做,

docker run -d -p 4545:8553--name my-container my-image my-command

其中“8553”可以是您的应用程序默认内部端口,与“4545”外部端口合并

如果您的版本不推荐使用**--host**参数,请尝试此操作

const port = process.env.PORT || 3000;
  app.listen(port, "0.0.0.0", () => {
    console.log(
      `🚀 Application is running on: http://localhost:${port} env: ${process.env.NODE_ENV}`
    );
  });
