Http Go中的Google应用程序引擎自定义IP端口

你不能那样做。应用程序引擎不允许自定义http端口。应用程序引擎环境是高度沙盒化的，并且在它们各自的应用程序引擎环境中，并不是所有可以在纯Go（或Java或Python）中执行的操作都可用 发件人： 与Java和Python环境一样，并非所有标准库的功能都在沙箱中可用。例如，尝试打开套接字或写入文件将返回os.EINVAL错误 Go应用程序在一个安全的“沙盒”环境中运行，并减少了一组库。例如，应用程序无法将数据写入本地文件系统或进行任意网络连接。相反，应用程序使用应用程序引擎提供的可扩展服务来存储数据并通过互联网进行通信
这确实是可能的，您所需要做的就是
goapp-service--port=3000goapp服务--host=0.0.0.0文档：Hmm，如我所见，我可以向GAE中的非标准端口发出请求：。我应该如何在Go for HTTP请求中获得自己的地址，以及当有人为该地址调用错误的端口时会发生什么情况（它无法通过，或者被转发到正常端口）？您现在提出的问题完全不同了。在最初的问题中，您询问了如何在AppEngine的非标准端口上运行http服务器。本页讨论如何执行http客户端请求。不同的事情。ip地址是计算机的属性，而不是Go。你不必选择appengine服务器的ip地址，谷歌会在他们选择的服务器之间跳转你的appengine代码。他们确实给了你一个稳定的DNS名称。与应用程序引擎上的非http端口的连接很可能被拒绝。
