http post action not reached in ASP.NET Core 3.1 web API controller - asp.net-core

Question

I have this controller
[ApiController]
[Route("api/[controller]")]
public class PlanningController: ControllerBase
{
public async Task<IActionResult> SaveTest([FromBody] TestData data)
{
return Ok(data);
}
public class TestData
{
public int Id { get; set; }
public string Name { get; set; }
}
This in Startup.cs
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHsts();
}
app.UseCors("default");
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
app.Run(context => context.Response.WriteAsync("Planificador API iniciada"));
}
I put a break point in the return but when I post this in postman
nothing happens in my controller the break point is not reached.
I don't understand the response received in postman
In VS 2022 I see this
Microsoft.AspNetCore.Hosting.Diagnostics: Information: Request
starting HTTP/1.1 POST
http://localhost:5001/api/planning/saveTest application/json 34
Microsoft.AspNetCore.Hosting.Diagnostics[1]
Microsoft.AspNetCore.Hosting.Diagnostics: Information: Request finished in 8.3968ms 200
Microsoft.AspNetCore.Hosting.Diagnostics[2]
Request finished in 8.3968ms 200
Any idea, please?
Thanks

Nothing happens in my controller the break point is not reached.I

Well, because of using [Route("planning")] before your PlanningController it is certainly overriding your application standard routing. So, your controller route has been changed. Thus, you shouldn't manipulate this routing [Route("api/[controller]")]
Correct Way:
[Route("api/[controller]")]
[ApiController]
public class PlanningController : ControllerBase
{
[HttpPost]
[Route("saveTest")]
public async Task<IActionResult> SaveTest([FromBody] TestData data)
{
return Ok(data);
}
}
Update:
Stratup.cs
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers();
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "TestWebAPIProject", Version = "v1" });
});
}
// 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", "TestWebAPIProject v1"));
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
Output:
Note: I would highly recommend you to have a look on our official document for Custom route constraints

The problem was tha in my controller I was injected IFileProvider wrong
Unable to resolve service for type 'Microsoft.Extensions.FileProviders.IFileProvider' while attempting to activate my controller
