How to read JSON Value in ASP.NET Core controller?

Question

How can I get value of request_id from the JSON inside my ASP.NET Core controller?

 { "request_id": "5nRJwCgt95yfmq9qVPrzei16568823342584", "number": "90001000000", "price": 0.028 }

I need to assign value of request_id to string ReqID .

My controller code is as follows

public async Task<ActionResult> RequestAuthenticate() { var client = new RestClient("https://api.mysmsprovider.com/v1/verify"); var request = new RestRequest("",Method.Post); request.AddHeader("Accept", "application/json"); request.AddHeader("Content-Type", "application/x-www-form-urlencoded"); request.AddParameter("application/x-www-form-urlencoded", "api_secret=123M&api_key=84545&code_length=4&from=NBL&to=90000001", ParameterType.RequestBody); RestResponse response = client.Execute(request); return Ok(response.Content); }

ASP.NET MVC already handles this. Put the model as a param to the action method.

For example, create a model the includes the data you are interested in receiving with properties matching the JSON fields:

 public class MyData { public string request_id {get;set;} }

And the controller

 public class MyController { public Result MyActionMethod(MyData myData) { // now myData.request_id contains 5nRJwCgt95yfmq9qVPrzei16568823342584 // you can use it/assign it to whatever you want var ReqID = myData.request_id; } }

Edit:

If you already have the JSON as a string, you can manually deserialize it into an object as follows:

 var myData = Newtonsoft.Json.JsonConvert.DeserializeObject<MyData>(json); // now myData.request_id will be the value you expect. var ReqID = myData.request_id;

Answer 2

you have to parse response.Content

 using Newtonsoft.Json; string ReqID= JObject.Parse(response.Content)["request_id"].ToString();
