如何在发布文件中设置 aspnetcore_environment? [英] How to set aspnetcore_environment in publish file?

问题描述

我有 ASP.NET Core 应用程序 (Web Api).文档已经解释了

更新 1

我知道我必须设置 ASPNETCORE_ENVIRONMENT 但是我不明白我们在哪里设置?在开发过程中，我可以在 launchSettings.json 的配置文件中设置它，但是问题是我们如何在发布到暂存或生产时设置它?我们是否在目标服务器上设置环境变量?

更新 2
我发现文章 here 解释了设置环境变量的不同方式.这部分回答了我的问题.但是，当我发布应用程序时，发布过程在发布 appsettings.{env.EnvironmentName}.json
时不遵守环境变量我为这个问题创建了单独的post

解决方案

您可以使用以下命令将所需的 ASPNETCORE_ENVIRONMENT 作为参数传入 dotnet publish 命令:

/p:EnvironmentName=Staging

例如dotnet publish/p:Configuration=Release/p:EnvironmentName=Staging

这将使用为您的项目指定的正确环境生成 web.config:

 <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Staging"/></环境变量>

I have ASP.NET Core application (Web Api). The documentation has explained working with multiple environments, however it failed to explain how to set aspnetcore_environment when publishing the web site.

So lets say if i have 3 environments Development, Staging and Production

1. In classic ASP.NET Web Application i used to create 3 build configurations. Development, Staging and Production ( Like shown in picture below). and then 3 .pubxml files, one for each configuration. Do i need to use the same approach for ASP.NET Core application as well?

2. How do i set aspnetcore_environment in .pubxml file?

3. If the approach specified in Question 1 is obsolete, then what's the alternate approach? ( I use Jenkins for CI)

Update 1

I understand that I have to set ASPNETCORE_ENVIRONMENT however I am not able to understand where do we set this? During development I can set this in profile in launchSettings.json, however question was how do we set this when publishing to staging or production? do we set environment variable on the target server itself?

Update 2
I found article here that explains different ways of setting environment variable. This partially answered my question. However when I publish the application, the publish process does not honor the environment variable while publishing appsettings.{env.EnvironmentName}.json
I have created separate post for that question

解决方案

You could pass in the desired ASPNETCORE_ENVIRONMENT into the dotnet publish command as an argument using:

/p:EnvironmentName=Staging

e.g. dotnet publish /p:Configuration=Release /p:EnvironmentName=Staging

This will generate out the web.config with the correct environment specified for your project:

    <environmentVariables>
      <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Staging" />
    </environmentVariables>
