我可以在 ASP.net Core 2.0 Preview 的 appsettings.json 中设置监听 URL 吗? [英] Can I set listen URLs in appsettings.json in ASP.net Core 2.0 Preview?

问题描述

我正在创建一个 ASP.net Core 2.0 应用程序以在 .net Core 2.0 运行时上运行，这两个应用程序目前都处于预览版本中.但是，我无法弄清楚如何让 Kestrel 使用默认 http://localhost:5000 侦听 URL 以外的其他内容.

I'm creating an ASP.net Core 2.0 app to run on the .net Core 2.0 runtime, both currently in their Preview versions. However, I cannot figure out how to have Kestrel use something other than the default http://localhost:5000 listen URL.

Google 提供的大多数文档都讨论了 server.urls 设置，即使在 1.0-preview 中，它似乎也已更改为 urls，但两者都不起作用(打开调试日志让 Kestrel 告诉我没有配置监听端点).

Most documentation that I could Google talks about a server.urls setting, which seems to have been changed even in 1.0-preview to just be urls, however neither works (turning on Debug logging has Kestrel telling me that no listen endpoints are configured).

很多文档也谈到了 hosting.json 并且我不能使用默认的 appsettings.json.但是，如果我比较推荐的加载新配置的方法，这看起来非常像新的 WebHost.CreateDefaultBuilder 方法可以，除了它加载 appsettings.json.

A lot of documentation also talks about a hosting.json and that I can't use the default appsettings.json. However, if I compare the recommended approach of loading a new config, this looks pretty much exactly like what the new WebHost.CreateDefaultBuilder method does, except that it loads appsettings.json.

我目前不明白 appsettings.json 和 IConfigureOptions<T> 是如何相关的(如果有的话)，所以我的问题可能源于对 codeServer/a> 确实如此.

I currently don't understand how appsettings.json and IConfigureOptions<T> are related, if at all, so it's possible that my trouble stems from a lack of understanding of what KestrelServerOptionsSetup actually does.

推荐答案

我已经解决了这个问题

public static IWebHost BuildWebHost(string[] args) => 
        WebHost.CreateDefaultBuilder(args)
            .UseConfiguration(new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("hosting.json", optional: true)
                .Build()
            )
            .UseStartup<Startup>()
            .Build();

和托管.json

{ "urls": "http://*:5005;" }
