如何设置环境名称(IHostingEnvironment.EnvironmentName)?

本文介绍了如何设置环境名称(IHostingEnvironment.EnvironmentName)?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

默认的ASP.NET Core Web项目在Startup.cs中包含以下行:

Default ASP.NET Core web project contain such lines in Startup.cs:

if (string.Equals(env.EnvironmentName, "Development", StringComparison.OrdinalIgnoreCase))
{
    app.UseBrowserLink();
    app.UseDeveloperExceptionPage(ErrorPageOptions.ShowAll);
}
else
{
    app.UseExceptionHandler("/Home/Error");
}

据我了解，EnvironmentName是处理Dev/Production环境的新方法.但这在Release构建配置上没有改变.那么设置不同的EnvironmentName的方法是什么?

As I understand, the EnvironmentName is a new way to handle Dev/Production environment. But it doesn't changes on Release build configuration. So what is the way to set a different EnvironmentName?

我可以想象应该在命令"中将其设置为服务器的参数.

I can imagine that it should be set in "Commands" as a parameter for server.

推荐答案

launchsettings.json

在属性"> launchsettings.json

At Properties > launchsettings.json

就像这样:

    {
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:1032/",
      "sslPort": 0
    }
  },
  "profiles": {
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Production"
      }
    },
    "WebAppNetCore": {
      "commandName": "Project",
      "launchBrowser": true,
      "launchUrl": "http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "web": {
      "commandName": "web",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}
