Question

Ich möchte Token zu Header für Webapi-Anfrage hinzufügen. wie kann ich das tun?

das ist mein Beispielcode

      { 
       var Token = "fdsf123546fskjhf-gsuyuhsh"; 

       //here add these token to header 

       return ? 
      }

Answer 1

1. Sie könnten ResponseMessageResult Klasse für diese Verwendung:

   public IHttpActionResult Authenticate(Login data) 
   { 
       var Token = "fdsf123546fskjhf-gsuyuhsh"; 
   
       var response = new HttpResponseMessage(); 
   
       response.Headers.Add("Authentication", Token); 
   
       return new ResponseMessageResult(response); 
   } 
   

2. Oder Ihr eigenes Ergebnis Klasse erstellen:

   public class HeaderActionResult : IHttpActionResult 
   { 
       private Tuple<string, string> header; 
   
       public HeaderActionResult(Tuple<string, string> header) 
       { 
        this.header = header; 
       } 
   
       public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken) 
       { 
        var response = new HttpResponseMessage(); 
   
        response.Headers.Add(header.Item1, header.Item2); 
   
        return Task.FromResult<HttpResponseMessage>(response); 
       } 
   } 
   
   public IHttpActionResult Authenticate(Login data) 
   { 
       var Token = "fdsf123546fskjhf-gsuyuhsh"; 
   
       return new HeaderActionResult(Tuple.Create("Authentication", Token)); 
   } 
   

3. Oder einen Header, um alle vorhandenen IHttpActionResult Objekt hinzufügen, eine Erweiterung mit Methode:

   public static class HttpActionResultExtensions 
   { 
       public static IHttpActionResult AddHeader(this IHttpActionResult actionResult, string name, string value) 
       { 
        return new HeaderActionResult(actionResult, name, value); 
       } 
   
       private class HeaderActionResult : IHttpActionResult 
       { 
        private readonly IHttpActionResult actionResult; 
   
        private string name; 
   
        private string value; 
   
        public HeaderActionResult(IHttpActionResult actionResult, string name, string value) 
        { 
         this.actionResult = actionResult; 
   
         this.name = name; 
   
         this.value = value; 
        } 
   
        public async Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken) 
        { 
         HttpResponseMessage httpResponseMessage = await this.actionResult.ExecuteAsync(cancellationToken); 
   
         httpResponseMessage.Headers.Add(this.name, this.value); 
   
         return httpResponseMessage; 
        } 
       } 
   }

Dieser Code arbeitet mir

public IHttpActionResult Authenticate(Login data) 
      { 
         Status = "success"; 
         Message = "You have been Authenticated successfully"; 
         var Token = "fdsf123546fskjhf-gsuyuhsh"; 
         var Result = new { Status = Status, Message = Message }; 

         var Response = Request.CreateResponse(HttpStatusCode.OK, Result); 
         Response.Headers.Add("AccessToken", Token.AccessToken); 

         return ResponseMessage(Response); 
      }
