如何处理.net Core 3.1自包含单个文件的Appsettings发布 [英] How to handle Appsettings for .net core 3.1 self contained single file publish

问题描述

我有一个新的.NET Core 3.1 worker类，它作为Windows服务托管.我正在使用由模板创建的默认appsettings.json和appsettings.environment.json. 在configureServices期间从hostContext加载appsettings

I have a new .NET Core 3.1 worker class that is hosted as a Windows Service. I am using the default appsettings.json and appsettings.environment.json that were created by the template. The appsettings is loaded from the hostContext during ConfigureServices

.ConfigureServices((hostContext, services) =>
   {
      services.AddHostedService<Worker>();
      services.Configure<BasicSettings>(hostContext.Configuration.GetSection("AppSettings"));
   });

我希望能够在部署应用程序后对其进行编辑，以便可以在生产环境中更改设置.在我的机器上调试期间，它可以正常工作.我更新了csproj文件，使其具有以下代码，以尝试使appsettings.json不包含在Single文件中.

I want to be able to edit the appsettings after it is deployed so that I can change settings in production. It works correctly during debugging on my machine. I updated the csproj file to have the following code to try and make the appsettings.json not get included in the Single file.

    <None Include="appsettings.json">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      <CopyToPublishDirectory>Always</CopyToPublishDirectory>
      <ExcludeFromSingleFile>true</ExcludeFromSingleFile>
    </None>
    <None Include="appsettings.Development.json;appsettings.Production.json;">
      <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      <CopyToPublishDirectory>Always</CopyToPublishDirectory>
      <DependentUpon>appsettings.json</DependentUpon>
      <ExcludeFromSingleFile>true</ExcludeFromSingleFile>
    </None>
  </ItemGroup>

添加此选项后，发布过程会创建单个exe以及3个appsettings.json文件，但无法解决.

After adding this the publish process does create the single exe as well as the 3 appsettings.json files but does not solve it.

当Windows服务启动时，它将单个exe扩展到文件夹C:\ Users \ ServiceLogonUser \ AppData \ Local \ Temp.net \ ServiceName \ SomeRandomThing，并且具有发布时项目中存在的appsettings.json.不是复制到exe旁边的appsettings.json.如果删除此文件夹，则会重新创建该文件夹，但会再次使用发布时存在的appsettings.json进行创建.如何通过单个exe发布从同一文件夹中读取appsettings.json，以便可以在发布后对其进行编辑?

When the windows service starts up it expands the single exe to the folder C:\Users\ServiceLogonUser\AppData\Local\Temp.net\ServiceName\SomeRandomThing and this has the appsettings.json that exists in the project at publish. Not the appsettings.json that is copied next to the exe. If I delete this folder, it is recreated but again with the appsettings.json that existed at publish. How with a single exe publish can it read the appsettings.json from the same folder so that the file can be edited in after publish?

推荐答案

我也遇到了同样的问题，并通过对项目文件的简单更改解决了该问题.

I too faced the same problem and solved with this simple change in the project file.

<None Include="appsettings.json">
  <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  <CopyToPublishDirectory>Always</CopyToPublishDirectory>
  <ExcludeFromSingleFile>false</ExcludeFromSingleFile>
</None>
<None Include="appsettings.Development.json;appsettings.Production.json;">
  <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  <CopyToPublishDirectory>Always</CopyToPublishDirectory>
  <DependentUpon>appsettings.json</DependentUpon>
  <ExcludeFromSingleFile>false</ExcludeFromSingleFile>
</None>

这会将appsettings.json和其他配置JSON文件捆绑到Single文件中，并在运行时解压缩到临时位置.

This will bundle the appsettings.json and other configuration JSON files into the Single file and will be unpacked to the temp location when ran.
