I am working with Nasdaq Fund Network Data Service first time. i am calling their one of the API where passing user id,pwd and access key but always getting 401 status code. i am not able to figure out what is wrong in my http call. please some one have a look at the code and tell me where i made the mistake for which i am getting 401 status code instead of right response.

here is my sample code where i could not share actual credentials and access key.

string url = "https://nfn.nasdaq.com/servicecall/tempsession";
 Uri u = new Uri(url);
    
 string username = "test1";
 string password = "test1";
 string accessKey = "my key";
    
 var payload = new Dictionary<string, string>
 {
   {"username", username},
   {"password", password},
   { "accesskey", accessKey}
 };
    
 string strPayload = JsonConvert.SerializeObject(payload);
 HttpContent c = new StringContent(strPayload, Encoding.UTF8, "application/x-www-form-urlencoded");
    
 var response = string.Empty;
 ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;
 using (var client = new HttpClient())
 {
  //client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessKey);
  //client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", "Bearer " + accessKey);
    
  HttpRequestMessage request = new HttpRequestMessage
  {
  Method = HttpMethod.Post,
  RequestUri = u,
  Content = c
  };
    
  var result = client.SendAsync(request).Result;
  if (result.IsSuccessStatusCode)
  {
  response = result.StatusCode.ToString();
  }
 }

ASP.NET Core MVC: How to secure token when passing with url

Mou_kol9-Aug-22 4:23

9-Aug-22 4:23

i got a application developed with asp.net core mvc where token is always passed with url. it seems if we pass token with each url then it is not secure way. so any time any other user can get url and appear before server as right user.

our token life is 24 hours.

sample url looks like http://localhost:48000/ACX/Default/Login?token=8kzRLdW8lQVIS0MrtlqdZJbmz9p22l33u1wspGOmLgCgEy2MG5XZ0JG1ovVZGiNX7KpAfBVn3[^]

This code is generating the token which would valid up to 24 hours:

 public IActionResult Login([FromBody]LoginModel user)  
 {  
     if (user == null)  
     {  
         return BadRequest("Invalid request");  
     }  
          
     if (user.UserName == "johncitizen" && user.Password == "abc@123")  
     {  
         var secretKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("KeyForSignInSecret@1234"));  
         var signinCredentials = new SigningCredentials(secretKey, SecurityAlgorithms.HmacSha256);  
    
         var tokeOptions = new JwtSecurityToken(  
             issuer: "http://localhost:2000",  
             audience: "http://localhost:2000",  
             claims: new List<Claim>(),  
             expires: DateTime.Now.AddMinutes(1440), // valid till 24 hours
             signingCredentials: signinCredentials  
         );  
    
         var tokenString = new JwtSecurityTokenHandler().WriteToken(tokeOptions);  
         return Ok(new { Token = tokenString });  
     }  
     else  
     {  
         return Unauthorized();  
     }  
 }

What can we do as a result token would be secure passing through URL? I want to change flow bit in such a way that if another user copy and paste the same URL, then he will not be able to access protected resource. So how to achieve and secure long life token?

Please guide me with approach in details. Thanks

For a user browsing your site, the token should be sent back in an HTTP-only, secure, same-site cookie.

This is driving me mad!!!

My hobby project a net core 6 Web app was running perfectly until yesterday - I'm now getting this error message whenever I try and return a view. I've obviously done something but I can't for the life of me think what. I can't catch the error either it just bombs and shows this error in the browser - any ideas ? The app runs as a daemon on a Debian box.

At a guess, you've either updated some libraries, or the .NET SDK, and something is now outdated.

Looking at the history[^], that method existed in the version of the code from November 2018:
razor-compiler/RazorConfiguration.cs at 32ff07c6d4a8037c61a5c75c26fc5f805da19b3a · dotnet/razor-compiler · GitHub[^]

But in March 2021, an optional parameter was added:
razor-compiler/RazorConfiguration.cs at f26e545a6712f186c84ed4ed956927be8ab52af6 · dotnet/razor-compiler · GitHub[^]

You have a library compiled against the 2018 version which is now running against the 2021 (or later) version.

I suspect you've updated the Microsoft.AspNetCore.Razor.Language[^] package, but not updated the Microsoft.AspNetCore.Mvc.Razor.Extensions[^] package to match. However, it's possible that your project doesn't directly reference either of these packages, and they're being pulled in as a transitive dependency of another package instead. You may need to dig through the dependency tree of each NuGet package you've referenced.

What's the difference between dotnet publish -c Release vs -c Debug?

Hi everyone,

I'm building my personal web site using ASP.Net and recently noticed something curious.
When publishing my project, it doesn't seem to matter if I use:

dotnet publish -c Release -o out

dotnet publish -c Debug -o out

Both commands will output (as far as I can tell) exactly the same binary. However shouldn't the release output be smaller/optimized?

Unfortunately I can't find much documentation regarding this config flag and as far as I can tell, the dotnet command is just passing it along to MSBuild which then select the proper configuration (profile?).

Does anyone know if it's supposed to work like that or am I doing something dumb?

PS: My csproj has nothing special in it as far as I can tell:

The output is MSIL, not machine code native to your CPU. That doesn't get generated until the code is loaded and running, call JIT Compiling. The code can be optimized for the CPU being used. Whether or not there are optimizations depends on how you've written your code and the CPU you run it on.

Debug builds do not run with optimizations, but contain more debugging information that may not be in the final executables.

Thanks but in that case I don't understand what is the purpose of the --configuration flag?

I understand that JIT will optimize things at runtime but I was expecting the --configuration to, at least, do some sort of (even if small) optimization when compiling (a la gcc compiling C code for example) to MSIL.

Many tutorials (especially Microsoft) almost always add that flag when publishing so it must do something but I can't understand what exactly.

Quote:

Yes this is exactly what I find confusing because my debug build doesn't have (as far as I can tell) any extra debugging information. It seems to be exactly the same as the release build (using -c Release)

You're also assuming that your code has stuff to optimize.

That's actually a very good point now that you mentioned it.

I didn't consider that and assumed that an ASP.Net app would be large enough to see some optimizations but I guess the libraries used are already optimized and my code doesn't have much stuff to optimize.

If you are using Entity Framework and you want to use BETWEEN, the standard way is to use => and<=.

I'd start by looking at what your SQL is trying to do and simplify it. From what I can see, your WHERE clause can be reduced to

SQL

vYear = 2022
AND EmpCode = 5229
AND NOT VacType IN (10, 15, 16, 17, 18, 19, 20, 21, 23, 24)
AND Result <> 1
AND ('12/07/2022' BETWEEN vStart AND vEnd
    OR CONVERT(DATETIME, '2022-07-13 00:00:00', 102) BETWEEN vStart AND vEnd
    )

I do not understand what the date ranges are for and why there are two different ways of representing dates unless your data has two sets of texts neither as real dates, in which case the comparisons are meaningless.
