.NET6.0 C#共享AppSettings.json
我正在使用一个多租户.NET6.0解决方案,该解决方案有许多嵌入式项目
以保持低位维护,我想集中和使用 /链接一个单个AppSettings。{Environment}。每个项目参考适当的文件。
因此,我目前正在尝试将其设置在控制台应用程序(将被部署为WebJob)中,并且在Dotnet Run中,我会获得非常奇怪的行为。
控制台应用中,我在项目文件中的sharedSettings.json中添加了一条路径
<ItemGroup>
<Content Include="..\SharedSettings\sharedsettings.development.json">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
<Content Include="..\SharedSettings\sharedsettings.production.json">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
<Content Include="..\SharedSettings\sharedsettings.staging.json">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
</ItemGroup>
在此 必需的配置设置。
但是,当我进行dotnet运行时,所需的JSON路径(来自同一文件)的AppSettings返回null。
这是我使用过文件的程序中的代码
//load the correct environment variables, i.e. Sevelopment / Staging / Production appsettings.JSON
string deployJSON = $"sharedsettings.{environment}.json";
string[] localPath = new string[] { "..", "SharedSettings", deployJSON };
var localJSON = Path.Combine(localPath);
Console.WriteLine(Directory.GetCurrentDirectory());
Configuration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile(localJSON, true, true)
.AddJsonFile(deployJSON, true, true)
.AddEnvironmentVariables()
.Build();
string queueName = Configuration.GetValue<string>("ConnectionStrings:ServiceBusName");
string serviceBusConnection = Configuration.GetValue<string>("ConnectionStrings:ServiceBusConnectionString");
Console.WriteLine(queueName);
Console.WriteLine(serviceBusConnection);
。CSSSISTS确认我可以到达文件,但是当我尝试运行dotnet运行时结果为何无效。
I'm working away at a multi-tenant .net6.0 solution which has a number of embedded projects
to keep maintenance low, I want to centralize and use / link one single appsettings.{environment}.JSON for the entire solution and have each project reference the appropriate files.
so I'm currently trying to set this up in a console app (which will be deployed as a webjob) and I'm getting a really weird behavior with dotnet run.
in this console app, I have added a path to the sharedsettings.json in the project file, i.e.
<ItemGroup>
<Content Include="..\SharedSettings\sharedsettings.development.json">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
<Content Include="..\SharedSettings\sharedsettings.production.json">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
<Content Include="..\SharedSettings\sharedsettings.staging.json">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
</ItemGroup>
And when I run the app using the play button i.e. via a deploy build in Visual Studio I can read the contents of the file and establish the required config settings.
However, when I do a dotnet run, the appsettings for the required JSON path (from the same file) returns null.
This is the code in the program.cs
//load the correct environment variables, i.e. Sevelopment / Staging / Production appsettings.JSON
string deployJSON = quot;sharedsettings.{environment}.json";
string[] localPath = new string[] { "..", "SharedSettings", deployJSON };
var localJSON = Path.Combine(localPath);
Console.WriteLine(Directory.GetCurrentDirectory());
Configuration = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile(localJSON, true, true)
.AddJsonFile(deployJSON, true, true)
.AddEnvironmentVariables()
.Build();
string queueName = Configuration.GetValue<string>("ConnectionStrings:ServiceBusName");
string serviceBusConnection = Configuration.GetValue<string>("ConnectionStrings:ServiceBusConnectionString");
Console.WriteLine(queueName);
Console.WriteLine(serviceBusConnection);
I have used file.exists to confirm I can get to the file, but I'm stumped as to why the results are null when I attempt to a dotnet run.

然后,我可以将sharedSettings.json作为本地文件引用
我现在所做的一切;
添加外部文件(作为链接)
[在这里] https:https:https: //Andrewlock.net/cluding-linked-files-from-outside-the-projection-directory-in-asp-net-core/
在配置构建器中引用文件,就像是本地文件一样
完美,但是dotnet运行仍然具有null值引用,除非我很难添加共享集群文件,即将它们嵌入每个项目中,而不是作为链接。 :生气的:
then i shuold be able to reference the sharedsettings.json as a local file
all i'm doing now is;
add an external file (as a link)
[here]https://andrewlock.net/including-linked-files-from-outside-the-project-directory-in-asp-net-core/
reference the file in the configuration builder as if it's a local file
the build is perfect, however dotnet run still has the NULL value references unless i hard add the sharedsettings files i.e. embed them in each project not as a link. :angry:
similar issue to this one。
这与基本路径有关。
similar issue to this one.
It was all to do with the base path.
这是一个较晚的答案,但是在尝试了不同的方法之后,我在项目的
.csproj
文件中最终提出了这一点:这将在构建之前每次将AppSettings复制到项目文件夹中。
This is a late answer, but after trying different methods I ended up with this in my Project's
.csproj
file:This copies the appsettings to the project folder every time before a build.
