使用appsettings.json配置Kestrel监听端口Dotnet Core 2预览2 [英] Using appsettings.json to configure Kestrel listen port Dotnet core 2 preview 2

问题描述

据我了解，为ASP Dotnet Core 2预览版1/2设置监听端口的正确方法是通过在appsettings.json中以以下格式创建一个Kestrel部分：

From what I understand the correct way of setting listen ports for ASP Dotnet Core 2 preview 1/2 is by creating a Kestrel section in the appsettings.json in the following format:

"Kestrel": {
    "EndPoints": { //Could also be Endpoints, it's a bit unclear
        "Http": {
        "Address": "127.0.0.1",
    "Port": 9001 //the port you want Kestrel to run on
},

我试图在Debian机器上设置示例webapp，但是当我启动该应用程序时，它写出该应用程序在端口5000上列出，默认端口。.

I have tried to set up the sample webapp on a Debian machine, but when I start the app, it writes out that the app is listing on port 5000, the default port..

我知道已读取appsettings.json，因为当我将日志记录级别更改为Trace时，我会在启动时获得更多信息，包括没有端点找到并且该应用程序将使用标准的5000端口。

I know that the appsettings.json is read, because when I change the logging level to Trace, I get more info upon startup, including that no Endpoints are found and the app will use the standard 5000 port.

我尝试在Github上搜索aspnet源代码，并且可以找到读取Kestrel部分的区域。来自配置（ https://github.com/aspb/a1b4a4b1e7b4a1b4e1b3c3b4e1b3c IdentityOIDCWebApplicationSample / MetaPackage / KestrelServerOptionsSetup.cs ），但是正如您所看到的，它看起来像是一个示例项目。

I have tried to search the aspnet source code on Github, and I can find a area where the Kestrel section is read from configuration (https://github.com/aspnet/Identity/blob/e38759b8a2de1b7a4a1c19462e40214b43c1cf3b/samples/IdentityOIDCWebApplicationSample/MetaPackage/KestrelServerOptionsSetup.cs), but as you can see it looks like a sample project.

我丢失了什么，这不是在ASP Dotnet核心2中配置Kestrel的标准方法？

What am I missing, isn't this the standard way to configure Kestrel in ASP Dotnet core 2?

推荐答案

通过appsettings.json对Kestrel配置的支持在2.0中已删除。

Support for Kestrel configuration via appsettings.json has been dropped in 2.0.

请参见此问题注释：

kestrel配置文件的支持从2.0.0减少。配置值需要在您的初始化代码中手动读取。

kestrel config file support was cut from 2.0.0. Config values need to be read manually in your initialization code.

要解决此问题，您可以在program.cs中执行类似的操作：

To get around this, you can do something like this in program.cs:

public static IWebHost BuildWebHost(string[] args) =>
 WebHost.CreateDefaultBuilder(args)
 .UseStartup < Startup > ()
 .UseKestrel((hostingContext, options) => 
 { 
  if (hostingContext.HostingEnvironment.IsDevelopment) {
   options.Listen(IPAddress.Loopback, 9001);
   options.Listen(IPAddress.Loopback, 9002, listenOptions => {
    listenOptions.UseHttps("certificate.pfx", "password");
   });
  }

 })
 .Build();
