Net Core 6 - can post Multi Params with FormUrlEncodedContent to web api - post

Question

The Web API controller:
[AllowAnonymous]
[HttpPost("validateUser")]
public async Task<IActionResult> validateUser(string email, string password)
{
var identityUsr = await _userMgr.FindByEmailAsync(email);
if (await _userMgr.CheckPasswordAsync(identityUsr, password))
{
var issuer = _config["Jwt:Issuer"];
var audience = _config["Jwt:Audience"];
int addMinutes = (int)Convert.ChangeType(_config["Jwt:addMinutes"], typeof(int));
var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["Jwt:Key"]));
var credentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);
JwtSecurityTokenHandler handler = new JwtSecurityTokenHandler();
var token = handler.CreateJwtSecurityToken(
audience: audience,
issuer: issuer,
//notBefore: DateTime.UtcNow,
//expires: DateTime.UtcNow.AddMinutes(addMinutes),
signingCredentials: credentials
);
var tokenHandler = new JwtSecurityTokenHandler();
var stringToken = tokenHandler.WriteToken(token);
return Ok(stringToken);
}
else
{
return Unauthorized();
}
return null;
}
Sender information:
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create([Bind("Id,UserName,NormalizedUserName,Email,NormalizedEmail,EmailConfirmed,PasswordHash,SecurityStamp,ConcurrencyStamp,PhoneNumber,PhoneNumberConfirmed,TwoFactorEnabled,LockoutEnd,LockoutEnabled,AccessFailedCount")] AspNetUser aspNetUser)
{
if (ModelState.IsValid)
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("https://localhost:44327");
var values = new List<KeyValuePair<string, string>>();
values.Add(new KeyValuePair<string, string>("email", "administrator#rapsosuites.com"));
values.Add(new KeyValuePair<string, string>("password", "Pn.14024284.Fm"));
var content = new FormUrlEncodedContent(values);
var result = await client.PostAsJsonAsync("/userApi/validateUser", content);
string resultContent = await result.Content.ReadAsStringAsync();
resultContent = resultContent + "//";
}
}
return View(aspNetUser);
}
I test with Postman and it works fine.
I test with the browser and it fails.
I make a change to this line and sending the parameters in the URL works fine !
var result = await client.PostAsync("/userApi/validateUser?email=administrator#rapsosuites.com&password=Pn.14024284.Fm", content);
For any reason the content object is not working sending the parameters

Answer 1

you can not use PostAsJsonAsync for FormUrlEncodedContent, try to use PostAsync
var content = new FormUrlEncodedContent(values);
var result = await client.PostAsync("/userApi/validateUser", content);
if you want to use PostAsJsonAsync you need much more code
fix the code
var values = new
{
email= "administrator#rapsosuites.com",
password="Pn.14024284.Fm"
};
var result = await client.PostAsJsonAsync("/userApi/validateUser", values);
and fix action
public async Task<IActionResult> validateUser([FromBody] ViewModel model)
and create a class
public class ViewModel
{
public string email {get; set;}
public string password {get; set;}
}
