Question

我想为webapi请求添加标头到标头。我怎样才能做到这一点？

这是我的示例代码

childDialog.setLocationRelativeTo( parentFrame );
childDialog.setVisible( true );

谢谢。

您可以使用ResponseMessageResult类：

public IHttpActionResult Authenticate(Login data)
{
    var Token = "fdsf123546fskjhf-gsuyuhsh";

    var response = new HttpResponseMessage();

    response.Headers.Add("Authentication", Token);

    return new ResponseMessageResult(response);
}

或者创建自己的结果类：

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));
}

或使用扩展方法向任何现有的IHttpActionResult对象添加标头：

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;
        }
    }
}

这段代码让我工作

    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);
            }
