ASP.NET Core托管环境变量被忽略 [英] ASP.NET Core hosting environment variable ignored

问题描述

我的登台服务器上有两个网站，它们都是在IIS中运行的ASP.NET Core站点.我已将环境变量ASPNETCORE_ENVIRONMENT设置为计算机范围内的Staging.这对于其中一个站点来说效果很好，但是另一个站点会忽略该变量，而是在生产模式下运行.我必须将托管环境配置为web.config文件，才能在暂存模式下运行它.

I have two web sites on my staging server, and both are ASP.NET Core sites that run in IIS. I have set the environment variable ASPNETCORE_ENVIRONMENT to Staging machine-wide. This works well for one of the sites, however the other ignores the variable and runs in production mode instead. I have to configure the hosting environment into the web.config file to run it in staging mode.

为什么一个站点不考虑环境变量?

Why does one site not take the environment variable into account?

在我的两个Startup(IHostingEnvironment env)构造函数中，我都使用环境变量:

In both of my Startup(IHostingEnvironment env) constructors, I use the environment variables:

public Startup(IHostingEnvironment env)
{
    var builder = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
        .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
        .AddJsonFile("logging.json")
        .AddEnvironmentVariables();  //   <---
        Configuration = builder.Build();
    }

推荐答案

如这个类似的问题中所述，窍门仅仅是设置应用程序池以加载用户变量(IIS->服务器->应用程序池->右键单击池->设置应用程序池默认值...->加载用户配置文件= True).

As said in this similar question, the trick was simply to set the app pool to load the user variables (IIS -> Server -> App Pools -> Right click on pool -> Set application pool defaults... -> Load User Profile = True).

我仅相应地配置了一个应用程序池，因此只有一个站点可以访问环境变量.

I configured only one of my app pools accordingly, thus only one of the sites could access the environment variables.
