How to add Base Url in swagger(C#)?

How can I add a base url on swagger ui like this in C#.
Please refer the below screenshot what I actually needed in which manner.

Have you tested this?
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "API V1");
});

If you want to add "mycoolapi" to the beginning of your default swagger UI URL, like this: http:///mycoolapi/swagger, then do the following:
In your Startup.cs Configure method:
app.UseSwagger(c =>
{
c.RouteTemplate = "mycoolapi/swagger/{documentname}/swagger.json";
});
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/mycoolapi/swagger/v1/swagger.json", "My Cool API V1");
c.RoutePrefix = "mycoolapi/swagger";
});
Then, if you currently have your launchSettings to launch browser at swagger UI upon startup (for development purposes), update your launchSettings.json file profiles section similarly:
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"launchUrl": "mycoolapi/swagger",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"MyProject.Web": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "mycoolapi/swagger",
"applicationUrl": "https://localhost:5001;http://localhost:5000",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}

Getting Error 404 Not Found when deployed asp.net core web api to aws elastic beanstalk

So i built a asp.net core web api app on .NET 5.0 , it works completely fine on my machine . Today i deployed it on elastic beanstalk AWS using the aws tools .
It doesn't show any error while deploying and stuff. it just returns me code 404 not found.

Please help me 🥲

So i just made a new app without https enabling, and it just worked as i remember.

MVC Web API NET CORE 5.0 Google Auth: No webpage was found for the web address: https://localhost:44307/signin-google

Just built a brand new web api, followed this example: https://learn.microsoft.com/en-us/aspnet/core/security/authentication/social/google-logins?view=aspnetcore-5.0 as best I could understand. Not using razor pages or a database. And had to add the following because it wouldn't run otherwise:
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = GoogleDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = GoogleDefaults.AuthenticationScheme;
})
Created the auth token in https://console.cloud.google.com/apis/credentials, stored them locally, and set the redirect to https://localhost:44307/signin-google as suggested.
This is my complete code.
using Microsoft.AspNetCore.Authentication.Google;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.OpenApi.Models;
namespace WebApplication3
{
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.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = GoogleDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = GoogleDefaults.AuthenticationScheme;
}).AddGoogle(options =>
{
IConfigurationSection googleAuthNSection =
Configuration.GetSection("Authentication:Google");
options.ClientId = googleAuthNSection["ClientId"];
options.ClientSecret = googleAuthNSection["ClientSecret"];
});
services.AddMvc(options =>
{
options.EnableEndpointRouting = false;
});
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "WebApplication3", 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", "WebApplication3 v1"));
}
app.UseHttpsRedirection();
app.UseRouting();
app.UseStaticFiles();
app.UseAuthorization();
app.UseMvc();
}
}
}
And the controller:
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using System.Security.Claims;
namespace WebApplication3.Controllers
{
[ApiController]
[Route("[controller]")]
public class UserController : ControllerBase
{
[HttpGet]
[Authorize]
public string Get()
{
return User.FindFirst(ClaimTypes.Email)?.Value;
}
}
}
And this is the launchsettings.json
{
"$schema": "http://json.schemastore.org/launchsettings.json",
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:6108",
"sslPort": 44307
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"launchUrl": "swagger",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"WebApplication3": {
"commandName": "Project",
"dotnetRunMessages": "true",
"launchBrowser": true,
"launchUrl": "swagger",
"applicationUrl": https://localhost:5001;http://localhost:5000",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}
}
After authenticating with Google, I get this 404 error. The Middleware that handles the redirect is not working. What am I missing?
This localhost page can’t be found No webpage was found for the web

HTTP ERROR 404

It's missing in Startup.cs:
app.UseAuthentication();

I get an error when I use weak password on my in ASP.Net Core application

This error does not happen when I test the application in development mode on my PC, but on the remote server it does. The app verify if user exist and the password requirements, but if I use a password like "1234" the app give me this error, but it does happen if I use a password like "#juan147-lop4s785"
This is the launchSettings.json file
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:63322",
"sslPort": 44361
}
},
"profiles": {
"IIS Express": {

}
},

"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Production"
//"ASPNETCORE_ENVIRONMENT": "Development"
}
}
}
}
and this us mi Startup.cs file
namespace UniJobs

//Incluye los roles de los usuarios a la app
.AddRoles<IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>();
services.AddControllersWithViews();
services.AddRazorPages();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseDeveloperExceptionPage();
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseSession();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapRazorPages();
});
}
}
}

It's likely that when creating a user, you're not checking whether it was successful or not and therefore when your "weak password" doesn't meet the default Identity options, it fails to create the user and then the database complains about the missing foreign key, resulting in your error.
Have a look here for the default Identity password options and how to customise them.
If you're using UserManager to create the user, you just need to check if it there were any errors and respond accordingly, something like the below:
var result = await UserManager.CreateAsync(user, password);
if(!result.Succeeded)
return result.Errors.Select(x => x.Description);
var roleResult = await UserManager.AddToRoleAsync(user, "User");
if (!roleResult.Succeeded)
return roleResult.Errors.Select(x => x.Description);

ASP.NET Core Webservice as localhost functional, but in IIS it gives an 404 Not Found Error

I have a problem with my ASP.NET Core Web Service.
I needed JWT for Authentication in my Angular project. That's why I made a service where the user needs to be checked, if he is authorized. I made it with .NET Core, because I have IIS Server.
When I run it locally with "dotnet run" I can make get or put requests locally. I tested it also in YARC plugin of Google Chrome by making a POST request with Payload (JSON with 2 key value pairs).
I uploaded the service in IIS Server, started it, gave the url (this time with the domain of server where IIS located) on YARC plugin in my local maschine again for POST request with the same payload. It gives me 404-Not Found Error.
Functional local url is: http://localhost:5000/api/auth/login
URL for IIS: http://myIISMachine:7471/api/auth/login (Port number is in the launchSettings.json file as well)
ConfigureServices function in my Startup.cs file:
public void ConfigureServices(IServiceCollection services)
{
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = "http://localhost:5000",
ValidAudience = "http://localhost:5000",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("MySecretKey"))
};
});
services.AddCors(options =>
{
options.AddPolicy("EnableCORS", builder =>
{
builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod().AllowCredentials().Build();
});
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}
And Configure function:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHsts();
}
app.UseCors("EnableCORS");
app.UseAuthentication();
//app.UseHttpsRedirection();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "api/{controller=Home}/{action=Index}/{id?}");
});
}
launchSettings.json file:
{
"$schema": "http://json.schemastore.org/launchsettings.json",
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:7471",
"sslPort": 44365

}
}
}
}
What am I doing here wrong? Or maybe is this something to do with the settings in IIS server? Could you help me please?
