How can I Post data using HttpWebRequest?

Solution 1
You can do by this
var request = HttpWebRequest.Create("http://example.com/api/Phrase/GetJDTO");
var postData = "Jlpt = 2";
var data = Encoding.ASCII.GetBytes(postData);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
using (var stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
but I suggest you use HttpClient
rather than HttpWebRequest
in this case
Solution 2
if (data != null)
{
request.ContentType = "application/json";
using (var stream = new StreamWriter(request.GetRequestStream()))
{
var serialized = JsonConvert.SerializeObject(data);
stream.Write(serialized);
}
}
else
{
request.ContentLength = 0;
}
where data is any object you want to send

I have this
HttpWebRequest
:var request = HttpWebRequest.Create("http://example.com/api/Phrase/GetJDTO"); request.ContentType = "application/json"; request.Method = "POST";
But I need to add a payload to the body of the request like this:
Jlpt = 2
Can someone help and tell me how I can add data to the POST ?
