当我使用 taghelper 触发控制器时，依赖注入不起作用
Dependency Injection not working when I using taghelper to trigger controller
我正在使用标签助手来激活控制器，但是当我专门使用 asp-controller 和 asp-action 时，它无法帮助我启用依赖注入服务和
网站崩溃了，
InvalidOperationException: Unable to resolve service for type 'Application.Interfaces.Repositories.ILessonService' while attempting to activate 'API.Controllers.LessonController'
但是当我在 <a href=" ">...</a> 中使用 href 时可以正常工作
<a class="collapse-item" asp-action="Index" asp-controller="Lesson">Reading</a>
<a class="collapse-item" href="/Lesson/Index">Listening</a>

这是控制器：

更新
用swagger可以正常使用，但是当我用另一个项目调用API时，出现了上面的错误。
我发现你的ToeicOnlineAdminApp中有一个LessonContrller，而api项目中有一个同名控制器，导致了这个问题。带有标签助手的锚生成 url 作为 api/lesson 以 api 控制器为目标。带有 href="/Lesson/Index" 的锚定位当前项目中的控制器。
我正在使用标签助手来激活控制器，但是当我专门使用 asp-controller 和 asp-action 时，它无法帮助我启用依赖注入服务和 网站崩溃了，
InvalidOperationException: Unable to resolve service for type 'Application.Interfaces.Repositories.ILessonService' while attempting to activate 'API.Controllers.LessonController'
但是当我在 <a href=" ">...</a> 中使用 href 时可以正常工作
<a class="collapse-item" asp-action="Index" asp-controller="Lesson">Reading</a>

这是控制器：
public class LessonController : ControllerBase
{
private readonly ILessonService _lessonService;
public LessonController(ILessonService lessonService)
{
_lessonService = lessonService;
}
// GET: /<controller>/
[HttpGet]
public async Task<IActionResult> Index([FromQuery] GetLessonsRequest request)
{
var lessons = await _lessonService.GetGuidelinesPaging(request);
return Ok(lessons);
}
}
Startup.cs:
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<ToeicOnlineContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("MvcToeicContext")));
services.AddApplicationLayer();
services.AddAutoMapper(typeof(Startup));
services.AddControllers().AddFluentValidation();
//DI
services.AddIdentity<User, Role>()

services.AddScoped<IUserClaimsPrincipalFactory<User>, UserClaimsPrincipalFactory<User, Role>>();

services.AddTransient(typeof(IGenericRepositoryAsync<>), typeof(GenericRepositoryAsync<>));
services.AddTransient<IUserService, UserService>();
services.AddTransient<IRoleService, RoleService>();
services.AddSwaggerExtension(Configuration);
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseSwagger();
app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "API v1"));
}
app.UseHttpsRedirection();
app.UseAuthentication();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>

});
}
更新 用swagger可以正常使用，但是当我用另一个项目调用API时，出现了上面的错误。
我发现你的ToeicOnlineAdminApp中有一个LessonContrller，而api项目中有一个同名控制器，导致了这个问题。带有标签助手的锚生成 url 作为 api/lesson 以 api 控制器为目标。带有 href="/Lesson/Index" 的锚定位当前项目中的控制器。
