从 POST 请求中获取令牌

如何解决从 POST 请求中获取令牌

我正在尝试从 POST 请求中获取令牌，但我不确定我应该如何读取响应。我也不太确定如何将用户名和密码放在消息正文中。我尝试使用 httpWReq.Credentials = new NetworkCredential("myUsername","myPassword") 但这不起作用。

文档说明：

这是我的代码：

HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create(
                    "https://myportalURI.com/token");

string s = "user=myUserName,password=myPassword";
var data = Encoding.Default.GetBytes(s);

httpWReq.Method = "POST";
httpWReq.ContentType = "application/json";
httpWReq.ContentLength = data.Length;

var newStream = httpWReq.GetRequestStream();

newStream.Write(data,data.Length);

newStream.Close();
