HTTP 请求标头自定义值不会发送到服务器 C#

Question

I am adding a custom header to my request. I can see it when I debug the code. But get an error that it's missing from the server.

HttpWebRequest request;
request = GenerateRequest("https://at.test.com/test/api/test/v1/TestApplications HTTP/1.1", content, "application/json", "POST");

request.Headers.Add("Custom-Signature", signature);
return GetResponseContent(request);

That is how I'm adding my header.

Answer 1

Long time ago since this question. I had the same problem using web api 2.0 and my solution was to use Request.Content.Headers instead of Request.Headers

and then i declared an extestion as below

  /// <summary>
    /// Returns an individual HTTP Header value
    /// </summary>
    /// <param name="headers"></param>
    /// <param name="key"></param>
    /// <returns></returns>
    public static string GetHeader(this HttpContentHeaders headers, string key, string defaultValue)
    {
        IEnumerable<string> keys = null;
        if (!headers.TryGetValues(key, out keys))
            return defaultValue;

        return keys.First();
    }

And then i invoked it by this way.

  var headerValue = Request.Content.Headers.GetHeader("custom-header-key", "default-value");

I hope it might be helpful
