Using C# to utilize an Angular 4 class

How can I handle this request in my C# web API?

Request:

this._http.post(
      this.url + 'api/Test',
      { auth: this.authClass},
      { headers: this.header }
    ).map(
      (res) => res.json()
      ).subscribe(
      (res) => {
        console.log("VALUE RECEIVED: ", res);
      })

AuthClass:

export class Auth{
    username:string = "";
    password:string = "";
}

I have a similar class in C# and need to figure out how to receive the class as a whole in C#.

I attempted:

[HttpPost]
public IHttpActionResult login(HttpRequestMessage request)
{
   var jsonString = await request.Content.ReadAsStringAsync();
   var model = JsonConvert.DeserializeObject<auth>(jsonString);
   return Ok();
}

The issue is that it cannot parse the JSON to auth. The JSON string being sent currently looks like this.

{
   "auth": {
       "username": "admin",
       "password": "admin1"
   }
}

If it's just:

{
   "username": "admin",
   "password": "admin1"
}

then it works without any issues. But I need it to consume the first JSON example.

Answer №1

Discussing the process of receiving the entire class in C#.

In this scenario, you won't be directly obtaining the entire class. The suggested method is to use JSON for data transfer, which will provide you with the Object properties only.

Further Information

I recommend looking into JSON serialization. There are numerous resources online that showcase examples of using C# with AngularJS.

Answer №2

Hello Arno,

Make sure to expect a JSON object in your web API method.

Utilize Json.Net to easily convert the JSON object into the C# object of your choice.

I trust this information will be beneficial to you.

Answer №3

After some consideration, it became clear that encapsulating the auth class within another class was the solution.

public class authReq
{
    public auth request { get; set; }
}

public class auth
{
    public string username { get; set; }
    public string password { get; set; }
}

Subsequently, I deserialized the authReq as follows.

var model = JsonConvert.DeserializeObject<register>(jsonString);
