I have problem with my simple app error handling middleware... When I tampered sql connect string, I get error but my middleware not catch it... someone know why?
{
public class ErrorHandlingMiddleware : IMiddleware // we need to add it to tell ASP that this class is middleware
{
public ErrorHandlingMiddleware()
{
}
//next - access to next middleware
public async Task InvokeAsync(HttpContext context, RequestDelegate next)
{
try
{
await next.Invoke(context); // here we call next middleware?
}
catch(Exception e)
{
context.Response.StatusCode = 500;
await context.Response.WriteAsync("Something went wrong");
}
}
}
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env,StudentSeeder seeder)
{
seeder.Seed();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseSwagger();
app.UseSwaggerUI(c => c.SwaggerEndpoint("/swagger/v1/swagger.json", "MyLibrus v1"));
}
//start of request
app.UseMiddleware<ErrorHandlingMiddleware>();
app.UseAuthentication();
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
public void ConfigureServices(IServiceCollection services)
{
services.AddScoped<ErrorHandlingMiddleware>();
...
some one can tell me why does it not work? I don't have error in my swagger but in vs...
