Question

当我尝试连接到我的c＃app获取azure令牌时遇到问题，我测试了PostMan的url和值，所有工作正常但在应用程序中发送给我这个错误：远程服务器返回错误：（400）错误请求。

这是我用于连接的方法，主机在Azure中，但自PostMan以来一切正常，这是服务器的网址http://testinglogi.azurewebsites.net/Token

public async Task<String> Login(string username, string password) {

        HttpWebRequest request = new HttpWebRequest(new Uri(String.Format("{0}Token", BASE)));
        request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
        request.Method = "POST";


        string postString = string.Format("username={0}&amp;password={1}&amp;grant_type=password",
            HttpUtility.HtmlEncode(username), HttpUtility.HtmlEncode(password));

        try
        {
            byte[] bytes = Encoding.UTF8.GetBytes(postString);
            using (Stream requestStream = await request.GetRequestStreamAsync())
        {

                requestStream.Write(bytes, 0, bytes.Length);
        }


            HttpWebResponse httpResponse = (HttpWebResponse)(await request.GetResponseAsync());
            string json;
            using (Stream responseStream = httpResponse.GetResponseStream())
            {
                json = new StreamReader(responseStream).ReadToEnd();
            }
            TokenResponseModel tokenResponse = (TokenResponseModel)JsonConvert.DeserializeObject(json);
            return tokenResponse.AccessToken;
        }
        catch (Exception ex)
        {
            throw new SecurityException("Bad credentials", ex);
        }

这是所有日志文件
