如何在 Azure 中托管 TCP 侦听器? [英] How can I host a TCP Listener in Azure?

问题描述

我希望在 Azure 中构建一个应用程序，它将充当 TCP 侦听器，在指定端口上接收 TCP 消息流，然后将信息添加到数据库中.传入的 TCP 通信将使用证书进行保护.

我正在考虑以下选项:

云服务工作者角色

这看起来肯定会工作.然而，这意味着我必须使用云服务，而我错过了应用服务提供的功能和简单性.云服务文档还具体介绍了如何打开需要的TCP端口.

应用服务

在逻辑应用程序(首选)中，但是这似乎本身并不支持 TCP 侦听器，因此我希望构建自定义 API 应用程序.或者，我可以创建一个 Web 作业.

但是我不确定这种方法是否有效，我有以下问题:

• 我可以在应用服务上公开任意 TCP 端口吗?
  • 虽然云服务文档专门描述了如何执行此操作，但我找不到应用服务的类似内容.因此，要么不需要配置，要么在应用服务中无法进行 TCP 通信.
• 我可以在逻辑应用程序、API 应用程序或 Web 作业中构建 TCP 侦听器吗，例如Azure 的体系结构是否支持 TCP 侦听器所需的行为?

我可以在 Azure 应用服务中托管 TCP 侦听器吗?

解决方案

云服务工作者角色

这看起来肯定会奏效.然而，这意味着我必须使用云服务，而我错过了应用服务提供的功能和简单性.Cloud Service 文档中还专门介绍了如何打开所需的 TCP 端口.

绝对有效.

在ServiceDefinition.csdef中:

<InputEndpoint name="RawTCP" protocol="tcp" port="54321" localPort="54321"/></端点>

否和否.只有 80/TCP 和 443/TCP 公开，并且唯一有效的协议是 HTTP.您无法使用应用服务进行自定义侦听器.

查看此处列出的沙箱限制:https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#network-endpoint-listening

如果应用服务页面上未提及此限制，请随时在 Azure 文档中提出拉取请求.

Service Fabric 将是一个很酷的第三(或第一?)选项:https://azure.microsoft.com/en-us/services/service-面料/

I am looking to build an application in Azure which will act as TCP listener, receive TCP message streams on a specified port, and then add the information to a database. The incoming TCP communication will be secured with a certificate.

I'm considering the following options:

Cloud Service Worker Role

This definitely looks like it will work. However that means I have to use a Cloud Service, and I miss out on the features and simplicity offered by the App Service. The Cloud Service documentation also specifically describes how to open the required TCP ports.

App Service

In a Logic App (preferred), however this doesn't seem to natively support a TCP listener, so I would look to build a custom API App. Alternatively I could create a Web Job.

However I'm not sure this approach will work, and I have the following questions:

• Can I expose arbitrary TCP ports on the App Service?
  • Whilst the Cloud Service documentation specifically describes how to do this, I can't find anything similar for the App Service. So, either the configuration is not required or TCP communication is just not possible within the App Service.
• Can I build a TCP listener inside an Logic App, API App, or Web Job, e.g. does the architecture of Azure support the behaviour required for a TCP listener?

Can I host a TCP Listener in an Azure App Service?

Definitely works.

In ServiceDefinition.csdef:

  <InputEndpoint name="RawTCP" protocol="tcp" port="54321" localPort="54321" />
</Endpoints>

No and No. Only 80/TCP and 443/TCP are exposed publicly and the only protocol that works is HTTP. You can't do custom listeners with App Service.

See the sandbox limitations listed here: https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#network-endpoint-listening

Feel free to make a pull request in the Azure documentation if this limitation is not mentioned on the App Service page.

Service Fabric would be a cool 3rd (or 1st?) option: https://azure.microsoft.com/en-us/services/service-fabric/
