如何以编程方式添加用户机密？

Question

I would like to create User Secrets from a .NET Core Application without using the dotnet executable. Is there a standard way to do it?

Answer 1

Just create secrets.json file where it should be and follow the guide you mentioned. File path (In my case directory UserSecrets did not exist, so I had to create it beforehand):

%APPDATA%\Microsoft\UserSecrets\<user_secrets_id>\secrets.json

where <user_secrets_id> is GUID.

File content:

{
  "PW": "test"
}

Edit your .csproj file to include secrets id, replace GUID with your value

<UserSecretsId>da96d8db-5651-4925-b1e9-2fdbbea03e81</UserSecretsId>

And finally modify Startup.cs file to include your secrets

public Startup(IHostingEnvironment env)
{

    var builder = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile("appsettings.json",
                        optional: false,
                        reloadOnChange: true)
        .AddEnvironmentVariables();

    if (env.IsDevelopment())
    {
        builder.AddUserSecrets<Startup>(); // this line adds secrets to configuration
    }

    Configuration = builder.Build();

    var a = Configuration["PW"]; // value: test
}
