我有一个关于在blazor应用程序中使用框架引用的问题。
我尝试使用ProblemsDetails类，它是Microsoft.AspNetCore.Mvc共享框架的一部分。Blazor应用参考使用的库之一

标签在.csproj文件中。
当我尝试构建Blazor应用程序时，我得到：

  1. error NETSDK1082: There was no runtime pack for M 
  2. icrosoft.AspNetCore.App available for the specified RuntimeIdentifier 'browser-wasm'.

字符串
解决办法是什么？
有没有办法在blazor中引用ProblemDetails类和相关的类，比如ValidationProblemDetails？

以下是库的csproj文件：

  1. <Project Sdk="Microsoft.NET.Sdk">
  3.   <PropertyGroup>
  4.     <TargetFramework>net6.0</TargetFramework>
  5.     <ImplicitUsings>enable</ImplicitUsings>
  6.     <Nullable>enable</Nullable>
  7.   </PropertyGroup>
  9.   <ItemGroup>
  10.     <FrameworkReference Include="Microsoft.AspNetCore.App" />
  11.   </ItemGroup>
  13.   <ItemGroup>
  14.     <ProjectReference Include="..\DataLayer\DataLayer.csproj" />
  15.     <ProjectReference Include="..\BizLogic\BizLogic.csproj" />
  16.   </ItemGroup>
  18.   <ItemGroup>
  19.     <PackageReference Include="AutoMapper" Version="12.0.0" />
  20.     <PackageReference Include="Dapper" Version="2.0.123" />
  21.     <PackageReference Include="FluentValidation" Version="10.4.0" />
  22.     <PackageReference Include="Microsoft.EntityFrameworkCore" Version="6.0.10" />
  23.     <PackageReference Include="Microsoft.Extensions.Http" Version="7.0.0" />
  24.     <PackageReference Include="Newtonsoft.Json" Version="13.0.3" />
  25.   </ItemGroup>
  27. </Project>

这里是blazor wasm.csproj文件：

  1. <Project Sdk="Microsoft.NET.Sdk.BlazorWebAssembly">
  3.   <PropertyGroup>
  4.     <TargetFramework>net6.0</TargetFramework>
  5.     <Nullable>enable</Nullable>
  6.     <ImplicitUsings>enable</ImplicitUsings>
  7.   </PropertyGroup>
  9.   <ItemGroup>
  10.     <PackageReference Include="AutoMapper.Extensions.Microsoft.DependencyInjection" Version="12.0.1" />
  11.     <PackageReference Include="Blazored.FluentValidation" Version="2.0.1" />
  12.     <PackageReference Include="FluentValidation" Version="11.7.1" />
  13.     <PackageReference Include="FluentValidation.DependencyInjectionExtensions" Version="11.7.1" />
  14.     <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="6.0.8" />
  15.     <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.DevServer"
  16.       Version="6.0.8" PrivateAssets="all" />
  17.     <PackageReference Include="MudBlazor" Version="6.10.0" />
  18.     <PackageReference Include="Newtonsoft.Json" Version="13.0.3" />
  19.   </ItemGroup>
  21.   <ItemGroup>
  22.     <ProjectReference Include="..\ServiceLayer\ServiceLayer.csproj" />

问题：https://github.com/dotnet/aspnetcore/issues/36970
此分类上一篇：https://github.com/dotnet/aspnetcore/issues/30910
从前面的链接我试图取代框架参考Microsoft.AspNetCore.Mvc使用Microsoft.AspNetCore.Mvc.Core包。
似乎引用Microsoft.AspNetCore.Mvc.Core可以解决前面提到的错误NETSDK1082。
但现在我得到了一个不同的错误：

  1. error CS0234: The type or namespace name 'ApplicationPartAttributeA
  2. ttribute' does not exist in the namespace 'Microsoft.AspNetCore.Mvc.ApplicationParts' (are you missing an assembly reference?)

下面是使用ProblemDetails的库中的代码摘录：

  1. public async Task AddServiceResponsesAsync(List<ServiceResponse> responses)
  2.         {
  3.             HttpClient client = _clientFactory.CreateClient();
  5.             string uri = _configuration.GetConnectionString("web-api-uri-base-adress");
  7.             client.BaseAddress = new Uri(uri);
  9.             JsonSerializer serializer = JsonSerializer.Create();
  10.             StringWriter stringWriter = new StringWriter();
  11.             serializer.Serialize(stringWriter, responses);
  13.             StringContent content = new StringContent(stringWriter.ToString(), Encoding.UTF8, "application/json");
  15.             var response = await client.PostAsync("service-responses", content);
  17.                     var detailedError = await response.Content.ReadFromJsonAsync<ProblemDetails>();
  18. }

我好像做错了什么。请帮帮忙。谢谢。

从你的问题中，我推测你想在Blazor Wasm Client项目中解析从服务器返回的ProblemDetails，这样你就可以在客户端上检查ProblemDetails并相应地执行操作。
要记住的关键是，从服务器返回的数据只是从ProblemDetails类序列化的Json。
因此，任何具有相同属性的类都适合于示例化。
我的解决方案是创建一个ClientProblemDetails类：

  1. public class ClientProblemDetails
  2. {
  3.     [JsonPropertyName("type")]
  4.     public string Type { get; set; } = default!;
  6.     [JsonPropertyName("title")]
  7.     public string Title { get; set; } = default!;
  9.     [JsonPropertyName("status")]
  10.     public int Status { get; set; } = default!;
  12.     [JsonPropertyName("detail")]
  13.     public string Detail { get; set; } = default!;
  15.     [JsonPropertyName("instance")]
  16.     public string Instance { get; set; } = default!;
  17. }

字符串
然后，如果来自服务器的响应是BadRequest，则将其转换为ClientProblemDetails，然后将其传递给客户端应用程序。这样，您就不需要从客户端引用Microsoft.AspNetCore.App框架。

  1. if (httpResponse.StatusCode == HttpStatusCode.BadRequest)
  2. {
  3.     ClientProblemDetails clientProblemDetails = httpResponse.Content
  4.         .ReadFromJsonAsync<ClientProblemDetails>();
  6.     // Pass clientProblemDetails around the client as you wish
  7.     // or throw a custom "ApiCallException", so can catch
  8.     // exceptions from higher up the stack and inspect with
  9.     // ex.ProblemDetails.Type, etc.
  10.     // e.g.:
  11.     throw new ApiCallException(clientProblemDetails);
  12. }
  14. class ApiCallException : Exception
  15. {
  16.     public ClientProblemDetails ProblemDetails { get; }
  18.     public ApiCallException(ClientProblemDetails details) : base(details.Title)
  19.     {
  20.         ProblemDetails = details;
  21.     }
  23. }
