Nestjs websocket 端口通过配置和 cors

Question

我想知道如何根据配置服务提供者的特定端口https://docs.nestjs.com/websockets/gateways ?例如，我想在生产环境中收听 8500，但在登台环境中收听 8080。

以及如何启用 cors，因为当我连接到不同域中的套接字服务器时，它显示 has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status .

Answer 1

const options = {
  cors: {
    origin: ["example1.com", "example2.com"],
    methods: ["GET", "POST"],
    credentials: true
  }
}
@WebSocketGateway(options)
