✅ (solved) dot net cannot send post request to my endpoint

Hey guys, need some help understanding why my dotnet app is not working:

let btn = document.getElementById('submit');
let URL = 'localhost:8080/controller';
document.getElementById('result-value').value = false.toString();


btn.onclick = (e) => {
    let req = new XMLHttpRequest();
    req.open("POST", URL, true);

    req.setRequestHeader("Content-Type", "application/json;charset=UTF-8");

    req.onreadystatechange = function () {
        if (req.readyState == XMLHttpRequest.DONE && req.status == 200) {
            let answer = JSON.parse(req.response);
            if (typeof (answer.access) != 'undefined') {
                document.getElementById('result-value').value = answer.access.toString();
            }
        }
    }
    req.send(JSON.stringify({
        Login: document.getElementById('login').value,
        Password: document.getElementById('pass').value
    }));
};

let btn = document.getElementById('submit');
let URL = 'localhost:8080/controller';
document.getElementById('result-value').value = false.toString();


btn.onclick = (e) => {
    let req = new XMLHttpRequest();
    req.open("POST", URL, true);

    req.setRequestHeader("Content-Type", "application/json;charset=UTF-8");

    req.onreadystatechange = function () {
        if (req.readyState == XMLHttpRequest.DONE && req.status == 200) {
            let answer = JSON.parse(req.response);
            if (typeof (answer.access) != 'undefined') {
                document.getElementById('result-value').value = answer.access.toString();
            }
        }
    }
    req.send(JSON.stringify({
        Login: document.getElementById('login').value,
        Password: document.getElementById('pass').value
    }));
};

I have such js frontend that sends a post request to my 'localhost:8080/controller' I have such coontroller in my dotnet app:

using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;

namespace YourNamespace.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class LoginController : ControllerBase
    {
        private static readonly Dictionary<string, string> Users = new Dictionary<string, string>
        {
            {"admin", "admin"},
            {"dsfsdf", "sdfsdf"}
        };

        [HttpPost]
        public IActionResult Post([FromBody] LoginRequest request)
        {
            if (Users.TryGetValue(request.Login, out var password) && password == request.Password)
            {
                return Ok(new { access = true });
            }

            return Ok(new { access = false });
        }
    }

    public class LoginRequest
    {
        public string Login { get; set; }
        public string Password { get; set; }
    }
}

using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;

namespace YourNamespace.Controllers
{
    [ApiController]
    [Route("[controller]")]
    public class LoginController : ControllerBase
    {
        private static readonly Dictionary<string, string> Users = new Dictionary<string, string>
        {
            {"admin", "admin"},
            {"dsfsdf", "sdfsdf"}
        };

        [HttpPost]
        public IActionResult Post([FromBody] LoginRequest request)
        {
            if (Users.TryGetValue(request.Login, out var password) && password == request.Password)
            {
                return Ok(new { access = true });
            }

            return Ok(new { access = false });
        }

here is my program.cs file:

// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.UseAuthorization();

app.MapControllers();

app.Run("http://localhost:8080");

ero•2y ago

Your url is wrong

AlexeySOP•2y ago

in js file?

ero•2y ago

Your controller sits at /login Yes

AlexeySOP•2y ago

I thought: [Route("[controller]")] means /controller

ero•2y ago

No, that would be [Route("controller")] The brackets format the class name

AlexeySOP•2y ago

gotcha well, changed it and still doesn't work

AlexeySOP•2y ago

AlexeySOP•2y ago

let URL = 'localhost:8080/login';

Pobiega•2y ago

not sure you can issue requests like that from a file:// use live-server or similar to run your frontend so it uses the http protocol you're getting a CORS error because your frontend and backend have different origins atm so you'll also need to disable CORS in .NET

AlexeySOP•2y ago

hmm

AlexeySOP•2y ago

well it appears to be working if I send it by curl

Pobiega•2y ago

well yes, since CURL uses the http protocol 🙂 unlike file:// also, CURL issues a raw http request. its not a browser, so there is no CORS going on. CORS is a client-side thing built into browsers to prevent redirect attacks

AlexeySOP•2y ago

so what's the fastest way to "host" my html file?

Pobiega•2y ago

are you using VS Code?

AlexeySOP•2y ago

yup

I've never used c# before in my life

Pobiega•2y ago

app.UseCors(corsPolicyBuilder =>
{
    corsPolicyBuilder.AllowAnyOrigin();
    corsPolicyBuilder.AllowAnyMethod();
    corsPolicyBuilder.AllowAnyHeader();
});

app.UseCors(corsPolicyBuilder =>
{
    corsPolicyBuilder.AllowAnyOrigin();
    corsPolicyBuilder.AllowAnyMethod();
    corsPolicyBuilder.AllowAnyHeader();
});

this will "disable" cors by allowing everything

AlexeySOP•2y ago

well

});

app.Run("http://localhost:8080");

I put it like that still getting cors errors

Pobiega•2y ago

well yes it needs to go before any other app.Use middleware order matters

Pobiega•2y ago

looks better.

AlexeySOP•2y ago

just right after app declaration

AlexeySOP•2y ago

AlexeySOP•2y ago

just sent a post request via curl:

warn: Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3]
      Failed to determine the https port for redirect.

warn: Microsoft.AspNetCore.HttpsPolicy.HttpsRedirectionMiddleware[3]
      Failed to determine the https port for redirect.

logged this

Pobiega•2y ago

thats a different middleware, probably not related. okay, lets re-order some middleware and add another

AlexeySOP•2y ago

I'm ready

Pobiega•2y ago

app.UseHttpsRedirection();
app.UseRouting();
app.UseCors(corsPolicyBuilder =>
{
    corsPolicyBuilder.AllowAnyOrigin();
    corsPolicyBuilder.AllowAnyMethod();
    corsPolicyBuilder.AllowAnyHeader();
});

app.UseHttpsRedirection();
app.UseRouting();
app.UseCors(corsPolicyBuilder =>
{
    corsPolicyBuilder.AllowAnyOrigin();
    corsPolicyBuilder.AllowAnyMethod();
    corsPolicyBuilder.AllowAnyHeader();
});

AlexeySOP•2y ago

what parts of code should I delete to put this

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

app.UseHttpsRedirection();
app.UseRouting();
app.UseCors(corsPolicyBuilder =>
{
    corsPolicyBuilder.AllowAnyOrigin();
    corsPolicyBuilder.AllowAnyMethod();
    corsPolicyBuilder.AllowAnyHeader();
});

app.Run("http://localhost:8080");

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

app.UseHttpsRedirection();
app.UseRouting();
app.UseCors(corsPolicyBuilder =>
{
    corsPolicyBuilder.AllowAnyOrigin();
    corsPolicyBuilder.AllowAnyMethod();
    corsPolicyBuilder.AllowAnyHeader();
});

app.Run("http://localhost:8080");

like this?

Pobiega•2y ago

uhm you removed all the middleware after cors, including your controller mapping

AlexeySOP•2y ago

true

Pobiega•2y ago

dont do that :p re add everything after cors, except HttpsRedirection

looks better give it a spin

AlexeySOP•2y ago

still nope :(

Pobiega•2y ago

hang on, creating a new project to test

AlexeySOP•2y ago

by the way

yeah, CORS errors. but we already knew that can you pass me your html?

AlexeySOP•2y ago

sure

maybe something is wrong with my controller:

nah thats not it the cors is the issue for sure, but I cant seem to reproduce for some reason

AlexeySOP•2y ago

well yeah maybe something wrong with my pc after all idk

Pobiega•2y ago

I got it working when I swapped to fetch instead of using XmlRequest

AlexeySOP•2y ago

hmm unfortunately I cannot change any front end code only backend

Pobiega•2y ago

okay.

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();

app.UseHttpsRedirection();
app.UseRouting();

app.UseCors(x =>
{
    x.AllowAnyHeader();
    x.AllowAnyMethod();
    x.AllowAnyOrigin();
});

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseAuthorization();

app.MapControllers();

app.Run();

AlexeySOP•2y ago

Pobiega•2y ago

AlexeySOP•2y ago

me too hmm wait

AlexeySOP•2y ago

Pobiega•2y ago

read the top error ah I know the issue your URL let URL = "https://localhost:7242/login"; you didnt specify a protocl in your URL

AlexeySOP•2y ago

yess it works thanks man stupid error

Pobiega•2y ago

thats what we get for not reading the error message properly 🙂

AlexeySOP•2y ago

yup and it changes here to true

AlexeySOP•2y ago

yeah thanks for help man, really appreciate it

Pobiega•2y ago

I would highly suggest using fetch and async instead of XmlHttpRequest thou

AlexeySOP•2y ago

yeah but the code is not mine, that was a, let's say an "exercise"

Pobiega•2y ago

right

btn.onclick = async (e) => {
  const response = await fetch(URL, { method: "POST" });
  const content = await response.json();
  resval.value = content.access;
};

btn.onclick = async (e) => {
  const response = await fetch(URL, { method: "POST" });
  const content = await response.json();
  resval.value = content.access;
};

like, how much nicer is that 😄

AlexeySOP•2y ago

decided to take a part in hackaton and they haven't even mentioned anywhere that you would need to write code in c# yeah looks way better

Angius•2y ago

Was about to say, why would anybody use XmlHttpRequest nowadays lol
