Doubt with Webrequest get method passing token

Question

I’m trying to read the data of an order, where I send the information via get, Error: Unable to send content with this verb type.

     public string ConsultaPedido(string urlpedido, string NumeroPedido)
        {
            var request = (HttpWebRequest)WebRequest.Create(urlpedido + "/" + NumeroPedido +"/");
            request.ContentType = "application/json";
            request.Method = "GET";

            using (var streamWriter = new StreamWriter(request.GetRequestStream()))
            {
                string json = new JavaScriptSerializer().Serialize(new
                {
                    AuthToken = "8686330657058660259"
                });

                streamWriter.Write(json);
            }

            var response = (HttpWebResponse)request.GetResponse();
            using (var streamReader = new StreamReader(response.GetResponseStream()))
            {
                return streamReader.ReadToEnd();
            }
        }

Answer 1

GET method does not contain Body, or you need to send the AuthToken in Header as our colleague said. Try it like this:

public string ConsultaPedido(string urlpedido, string NumeroPedido)
    {
        var request = (HttpWebRequest)WebRequest.Create(urlpedido + "/" + NumeroPedido +"/");
        //request.ContentType = "application/json"; removendo o body
        request.Method = "GET";

        /*using (var streamWriter = new StreamWriter(request.GetRequestStream()))
        {
            string json = new JavaScriptSerializer().Serialize(new
            {
                AuthToken = "8686330657058660259"
            });

            streamWriter.Write(json);
        }Não há necessidade de adicionar um body, ao invés disso adicione no Header.*/

        request.Headers["AuthToken"] = "8686330657058660259";//Adicionando o AuthToken  no Header da requisição

        var response = (HttpWebResponse)request.GetResponse();
        using (var streamReader = new StreamReader(response.GetResponseStream()))
        {
            return streamReader.ReadToEnd();
        }
    }

I removed the Header add line from that question in English

Answer 2

You are trying to send a Body in a GET verb where it is not possible. What you can and is most common is you send the token in Header.

Example:

Normally I do so, an example method of a test I did:

private List<UserCoupon> GetUserCoupons()
{
    var client = new HttpClient { BaseAddress = new Uri(APIUrl) };

    if (Session["User"] != null)
    {
        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", GetToken());

        int userId = GetUserId();
        client.DefaultRequestHeaders.Accept.Add(
            new MediaTypeWithQualityHeaderValue("application/json"));

        var response = client.GetAsync($"api/coupon/couponlistbyuser?UserId={userId}").Result;

        if (response.IsSuccessStatusCode)
        {
            var ret = response.Content.ReadAsStringAsync();
            var list = JsonConvert.DeserializeObject<List<UserCoupon>>(ret.Result);
            return list;
        }
    }
    return null;
}
