.Net Core警告未配置XML加密器 [英] .Net Core warning No XML encryptor configured

问题描述

启动服务时（Docker容器中.Net Core 2.2上的API），我收到警告：

When I start my service (API on .Net Core 2.2 in Docker container) I've got a warning:

没有XML加密器已配置。密钥
{daa53741-8295-4c9b-ae9c-e69b003f16fa}可以
的未加密形式持久存储。

No XML encryptor configured. Key {daa53741-8295-4c9b-ae9c-e69b003f16fa} may be persisted to storage in unencrypted form.

我没有配置DataProtection。我找到了配置DataProtection的解决方案，但不需要保存此密钥。对我来说，如果密钥只保留到应用程序重新启动，就可以了。但是我不需要在日志中看到此警告

I didn't configure DataProtection. I've found solutions to configure DataProtection but I don't need to save this key. For me if the key will only be persisted until the application restarts - it's Ok. But I don't need to see this warning in logs

有什么想法吗？我们该怎么做？

Any ideas? How can we do it?

我的启动类如下：

public class Startup {
  public Startup(IConfiguration configuration) {
    Configuration = configuration;
  }

  public IConfiguration Configuration { get; }

  public void ConfigureServices(IServiceCollection services) {
    services.AddMemoryCache();
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
    services.AddApiVersioning(o => o.ApiVersionReader = new HeaderApiVersionReader("api-version"));
  }

  public void Configure(IApplicationBuilder app, IHostingEnvironment env, IApplicationLifetime lifetime) {
    if (env.IsDevelopment()) {
      app.UseDeveloperExceptionPage();
    }

    app.UseMvc();

    lifetime.ApplicationStarted.Register(OnApplicationStarted);
    lifetime.ApplicationStopping.Register(OnShutdown);
  }

  public void OnApplicationStarted() {
    Console.Out.WriteLine($"Open Api Started");
  }

  public void OnShutdown() {
    Console.Out.WriteLine($"Open Api is shutting down.");
  }
}

也许也有帮助我在项目中的包裹

    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc.Versioning" Version="3.1.2" />

推荐答案

可能是权限错误，但您必须确定。尝试记录引发此错误的时间，我发现在开发环境中出现此错误的原因很多，通常是文件读取权限或找不到或没有文件。

It maybe permission error but you have to sure about. Try to log when thrown this error i see many reason to having this error on the development environment, generally file read permission or couldn't find or no file.

使用波纹管记录算法的主要功能，看看有什么问题

Wrap your main function with bellow logging algorithm and see whats wrong

public static void Main(string[] args)
        {
            CurrentDirectoryHelpers.SetCurrentDirectory();

            Log.Logger = new LoggerConfiguration()
                            .MinimumLevel.Information()
                            .MinimumLevel.Override("Serilog", LogEventLevel.Information)
                            .WriteTo.File("Logs/LogFrom_ProgramMain.txt")
                            .CreateLogger();

            try
            {
                var whb = WebHost.CreateDefaultBuilder(args).UseContentRoot(Directory.GetCurrentDirectory());

               //whb... your codes

                Log.Logger.Information("Information:blabla");

            }
            catch(Exception ex)
            {
                Log.Logger.Error("Main handled an exception: " + ex.Message);
            }
        }

不要轻易相信代码，然后看到

dont palter trust the code, and see

You can use this helper method if you need

internal class CurrentDirectoryHelpers
    {
        internal const string AspNetCoreModuleDll = "aspnetcorev2_inprocess.dll";

        [System.Runtime.InteropServices.DllImport("kernel32.dll")]
        private static extern IntPtr GetModuleHandle(string lpModuleName);

        [System.Runtime.InteropServices.DllImport(AspNetCoreModuleDll)]
        private static extern int http_get_application_properties(ref IISConfigurationData iiConfigData);

        [System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
        private struct IISConfigurationData
        {
            public IntPtr pNativeApplication;
            [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.BStr)]
            public string pwzFullApplicationPath;
            [System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.BStr)]
            public string pwzVirtualApplicationPath;
            public bool fWindowsAuthEnabled;
            public bool fBasicAuthEnabled;
            public bool fAnonymousAuthEnable;
        }

        public static void SetCurrentDirectory()
        {
            try
            {
                // Check if physical path was provided by ANCM
                var sitePhysicalPath = Environment.GetEnvironmentVariable("ASPNETCORE_IIS_PHYSICAL_PATH");
                if (string.IsNullOrEmpty(sitePhysicalPath))
                {
                    // Skip if not running ANCM InProcess
                    if (GetModuleHandle(AspNetCoreModuleDll) == IntPtr.Zero)
                    {
                        return;
                    }

                    IISConfigurationData configurationData = default(IISConfigurationData);
                    if (http_get_application_properties(ref configurationData) != 0)
                    {
                        return;
                    }

                    sitePhysicalPath = configurationData.pwzFullApplicationPath;
                }

                Environment.CurrentDirectory = sitePhysicalPath;
            }
            catch
            {
                // ignore
            }
        }
    }
